Description

Technical Field

[0001] This application claims priority based on Japanese Patent Application No. 2023-191897, filed on November 10, 2023, the contents of which are incorporated herein by reference.

[0002] This disclosure relates to a humidity regulating device. Background Technology

[0003] Previously, a method for adjusting humidity was disclosed.

[0004] For example, Patent Document 1 discloses the method of first preparing a water-saturated gas, then mixing the water-saturated gas with a dry gas to obtain the desired humidity-regulating gas.

[0005] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 2004-44867 Summary of the Invention The problem the invention aims to solve However, in the method described in Patent Document 1, when the humidifying gas is introduced into a predetermined moisture-importing device after exiting the mixing container, the humidity of the humidifying gas will change if any one of its pressure, temperature, or flow rate changes for some reason. To prevent humidity changes, water needs to be dispersed in a mist during humidification, and dry gas needs to be prepared for dehumidification. The amount of water used for humidification is determined based on parameters such as flow rate, pressure, and temperature. Furthermore, the amount of water dispensed needs to be precisely controlled for spraying. Therefore, it is difficult to adjust to the desired humidity.

[0006] Therefore, in view of the above-mentioned problems, the present invention aims to provide a humidity control device that can easily control humidity.

[0007] Solution for solving the problem In one aspect of this disclosure, the device is characterized by comprising: a moisture-regulating material capable of absorbing and releasing moisture; and a first temperature control element for controlling the temperature of the moisture-regulating material.

[0008] Invention Effects As described above, according to this disclosure, a humidity control device that allows for easy humidity control can be provided. Attached Figure Description

[0022] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Furthermore, the embodiments described below do not unreasonably limit the content of the present disclosure as described in the technical solution, and not all configurations described in these embodiments are necessary as solutions provided in the present disclosure.

[0023] Figure 1 This is a schematic diagram of the humidification device 100 according to the first embodiment. Figure 1 As shown, the humidity control device 100 of the first embodiment includes a humidity control material 10 and a first temperature control element 21.

[0024] The humidity-regulating material 10 is capable of absorbing and releasing moisture. The humidity-regulating material 10 absorbs and releases moisture based on its own temperature. This will be discussed later.

[0025] The first temperature control element 21 controls the temperature of the humidity-regulating material 10. Examples of the first temperature control element 21 include a Peltier element and a heater.

[0026] By controlling the temperature of the humidity-regulating material 10 using the first temperature control element 21, the humidity-regulating material 10 can control the amount of moisture absorbed and released, thus achieving the desired humidity level for the air passing through it. Therefore, the humidity-regulating device 100 includes at least the humidity-regulating material 10 and the first temperature control element 21, enabling easy humidity control. Furthermore, the humidity-regulating device 100 simplifies the process compared to devices that use different mechanisms to prepare and control the humidity of the humidified and dehumidified gases.

[0027] The following describes the humidity-regulating material 10.

[0028] Figure 2 This is a schematic cross-sectional view of the humidity-regulating material 10. For example... Figure 2 As shown, the humidity-regulating material 10 includes: an absorbent material 11 containing resin and / or clay minerals; and a humidity-regulating liquid 12, which is a humidity-regulating component that absorbs or releases moisture to regulate humidity. The humidity-regulating liquid 12 is impregnated in the absorbent material 11. Figure 3 As shown, the humidity-regulating material 10 absorbs moisture from the air in the environment where it is placed, or releases moisture from the material into the air to humidify it. Additionally, the absorbent material 11 may contain at least one component selected from the group consisting of absorbent resins and clay minerals.

[0029] The moisture-regulating material 10 can be in the form of powder, beads (granules), or blocks. Alternatively, the absorbent material 11 and the moisture-regulating liquid 12 can be dispersed in an adhesive and formed into a sheet.

[0030] The absorbent material 11 functions to retain the humidity-regulating liquid 12. Because the absorbent material 11 retains the humidity-regulating liquid 12, a humidity-regulating material 10 with a high surface area to volume ratio can be achieved. Therefore, the rate of moisture absorption or release can be increased. Thus, a humidity-regulating material 10 with a high humidity-regulating rate can be obtained.

[0031] The absorbent material 11 is preferably a water-absorbing resin (granules, powder). This allows the absorbent material 11 to appropriately impregnate the humidity-regulating liquid 12, further improving the humidity-regulating effect. Specific examples of the water-absorbing resin material are preferably ionic or nonionic resins. Examples of ionic resins include alkali metal salts of polyacrylic acid and starch-acrylate graft polymers. Specific examples of alkali metal salts of polyacrylic acid include sodium polyacrylate. Nonionic resins include, for example, at least one selected from the group consisting of vinyl acetate copolymers, maleic anhydride copolymers, polyvinyl alcohol, and polyepoxides. More preferably, the metal salt component forms hydrate crystals within a specified humidity range, thereby promoting rapid moisture absorption and release with a specific humidity range as a threshold.

[0032] The humidity-regulating liquid 12 absorbs moisture from the air, and preferably contains at least one selected from the group consisting of salts (hygroscopic substances) and polyols. This further enhances the humidity-regulating effect.

[0033] Specific examples of polyols include at least one selected from the group consisting of glycerol, propylene glycol, butylene glycol, pentanediol, trimethylolpropane, glycerol, ethylene glycol, diethylene glycol, triethylene glycol, and lactic acid, preferably polyols having three or more hydroxyl groups such as glycerol. Furthermore, polyols can form dimers or polymers.

[0034] As deliquescent substances, they are classified into salts and water-soluble organic compounds. Specific examples of salts are metal salts, such as sodium formate, potassium formate, ammonium formate, sodium acetate, potassium acetate, lithium acetate, ammonium acetate, sodium lactate, potassium lactate, sodium benzoate, potassium benzoate, sodium propionate, potassium propionate, calcium chloride, lithium chloride, magnesium chloride, calcium chloride, lithium chloride, potassium chloride, sodium chloride, zinc chloride, aluminum chloride, lithium bromide, calcium bromide, sodium hydroxide, sodium pyrrolidone carboxylate, potassium carbonate, calcium citrate, sodium citrate, potassium citrate, lithium citrate, etc. These salts may contain only one type or two or more. Among them, sodium formate, potassium formate, sodium acetate, potassium acetate, and potassium carbonate with a higher hygroscopic and hygroscopic water content per unit weight are preferred. Specific examples of water-soluble organic compounds include sugars such as sucrose, amylopectin, glucose, p-xylene, fructose, mannitol, and sorbitol, carboxylic acids such as citric acid, and amides such as urea.

[0035] The amount of the humidifying liquid 12 relative to the amount of the absorbent material 11 is preferably 1 part by weight or more and 1000 parts by weight or less relative to 100 parts by weight of the absorbent material. In this way, the amounts of the absorbent material 11 and the humidifying liquid 12 are appropriate, which can further improve the humidification function. In addition, the absorbent material 11 is preferably in the form of powder or beads (granules).

[0036] Figure 3 This diagram illustrates the configuration where the humidity-regulating material 10 is supported on the carrier 13. (See diagram below.) Figure 3 As shown, the humidity-regulating material 10 can also be carried or impregnated in the carrier 13. The carrier 13 carrying the humidity-regulating material 10 is preferably selected based on the application. When a large moisture absorption / desorption capacity is desired for humidity control purposes, the raw material that wets and retains the humidity-regulating liquid 12 is preferred. For example, it can be formed from hydrophilic fibers such as porous materials, nonwoven fabrics, or woven fabrics. Nonwoven fabrics with high water vapor permeability are particularly preferred. Furthermore, the carrier 13 may also contain an adhesive.

[0037] For example, the shape of the support 13 can be sheet-like, or it can be formed into various shapes such as flat, pleated, or honeycomb. For instance, the sheet material is first corrugated into a wave-like shape, and then bonded and integrated with a flat pad made of the same or different material as the sheet using an adhesive. Furthermore, the support 13 can also be flexible. The support 13 can be deformed. In other words, it can be maintained in any shape (bent shape, curved shape, etc.).

[0038] In addition to the above, the humidity conditioning material 10 can also be type A silica gel, type B silica gel, polymer adsorbent materials, etc.

[0039] Furthermore, the humidity-regulating component may contain the aforementioned metal salts. Additionally, other components may be added as additives to adjust the humidity threshold for crystallization. For example, components that form nucleating materials that are other metal salts, polyols, or hydrate crystals can be cited. Specific examples of nucleating materials include carboxylic acids having two or more carboxyl groups and amides having two or more amide groups. Carboxylic acids may be the aforementioned substances. The humidity threshold refers to the humidity level at which the humidity-regulating material 10 sometimes crystallizes when the humidity is low.

[0040] Furthermore, "humidification" refers to adjusting the relative humidity to bring it closer to a specified humidity range. Specifically, for example, when setting 50%RH as the specified relative humidity, such as... Figure 4 As shown, when the relative humidity is higher than 50%RH, the humidity-conditioning material 10 absorbs moisture (hygroscopic) to bring the humidity-conditioning material 10 to a specified relative humidity of 50%. On the other hand, when the relative humidity is lower than 50%RH, the humidity-conditioning material 10 releases moisture (dehumidifies) to bring the humidity-conditioning material 10 to a specified relative humidity of 50%. In this way, the humidity-conditioning material 10 is close to the specified relative humidity of 50%. In addition, the specified relative humidity range is generally related to the material and moisture content of the humidity-conditioning material 10. Specifically, for example, the specified relative humidity range is related to the moisture content in the humidity-conditioning liquid 12. Furthermore, the specified relative humidity refers to the baseline humidity at which the humidity-conditioning material 10 absorbs and releases moisture, and varies depending on the type and capacity of the humidity-conditioning material 10.

[0041] The humidity-regulating material 10 can be in the form of powder, beads (granules), blocks, or flakes, and can be used directly in the humidity-regulating device 100 of the first embodiment. Alternatively, the humidity-regulating material 10 can be carried on a ventilated substrate or filled into a container such as a column made of aluminum.

[0042] The preferred ventilation substrate is made of a material with high thermal conductivity. The internal structure of the ventilation substrate can also be corrugated, honeycomb, etc.

[0043] Thus, the humidity control device 100 of the first embodiment includes a humidity control material 10 and a first temperature control element 21. Therefore, the humidity control material 10 can absorb and release moisture, and the air passing through the humidity control material 10 can achieve the desired humidity.

[0044] As described above, the humidity conditioning material 10 can be a humidity conditioning material comprising an absorbent material 11 and a humidity conditioning liquid 12, a humidity conditioning material 10 formed into beads, a humidity conditioning material 10 formed into powder, a humidity conditioning material 10 formed into sheets, or other silica gels. The humidity conditioning material 10 is a material capable of absorbing and releasing moisture. Examples of humidity conditioning materials 10 include... Figure 4 The humidity curve shown indicates a humidity-regulating material with a rising trend to the upper right, and a humidity-regulating material whose humidity remains constant based on temperature.

[0045] The humidity-regulating material 10 can also be a liquid, but is preferably a solid. Examples of humidity-regulating materials 10 include beads.

[0046] The humidity-regulating material 10 is preferably a material whose initial equilibrium temperature is in the range of 35%RH-99%RH at room temperature. Furthermore, the humidity-regulating material 10 is preferably a material whose equilibrium humidity change due to temperature changes is within the range of ±10%RH from 0°C to 50°C.

[0047] The humidity control material 10 can be replaced or multiple different types of humidity control materials can be provided.

[0048] The humidity control device 100 of the first embodiment may also have the following structure: it includes a package containing a humidity control material 10 and a first temperature control element 21 wrapped with heat insulation material, wherein the heat of the first temperature control element 21 is not transferred to the humidity control material 10 and is not released to the outside.

[0049] In addition, such as Figure 1 As shown, the humidity control device 100 of the first embodiment preferably further includes: a temperature and humidity meter 30, which measures the humidity control space 50; a temperature and humidity meter 31, which measures the air passing through the humidity control material 10; and a calculation unit 40.

[0050] A temperature and humidity meter 31, which measures the air passing through the humidity-regulating material 10, measures the temperature and humidity of the air passing through the humidity-regulating material 10. Thus, the temperature and humidity meter 31, which measures the air passing through the humidity-regulating material 10, is installed downstream of the humidity-regulating material 10 in the circulating air.

[0051] The temperature and humidity meter 30 measuring the temperature and humidity within the humidity-controlled space 50 and the temperature and humidity meter 31 measuring the air passing through the humidity-controlled material 10 are both known temperature and humidity meters.

[0052] The arithmetic unit 40 obtains temperature and humidity from the temperature and humidity meter 30 installed in the humidity-controlled space 50 and the temperature and humidity meter 31 that measures the air passing through the humidity-controlled material 10, and determines the temperature of the first temperature control element 21 based on the temperature and humidity. The temperature of the first temperature control element 21 is set according to the desired humidity. The arithmetic unit 40 uses a computer (processor) or the like.

[0053] The humidity control device 100 of the first embodiment includes a temperature and humidity meter 30, 31 and an arithmetic unit 40, thereby enabling a more desired humidity and more detailed humidity control.

[0054] Alternatively, when installing the humidity-regulating material 10, the calculator 40 can automatically determine the type of the humidity-regulating material 10 and automatically set the control parameters based on the measurement results of the temperature and humidity meter 30 measuring the humidity in the humidity-regulating space 50 and the temperature and humidity meter 31 measuring the air passing through the humidity-regulating material 10.

[0055] Preferably, the humidity control device 100 of the first embodiment also includes a humidity control space 50 for air to flow into through the humidity control material 10. This allows for humidity control of the humidity control space 50. The humidity control space 50 can be a space of various sizes, such as a room. Furthermore, the air within the humidity control space 50 can also be sent to the humidity control material 10. That is, the air can be recirculated between the humidity control material 10, the humidity control space 50, and the humidity control material 10.

[0056] In addition, fan 60 can be used to circulate air. Fan 60 can be a fan that takes pressure loss into account.

[0057] Figure 5 This is a schematic diagram of a humidification device 100 equipped with two temperature control elements. (See diagram below.) Figure 5 Therefore, the humidity control device 100 of the first embodiment preferably also includes a second temperature control element 22.

[0058] The second temperature control element 22 is located downstream of the hygrometer 31 and controls the temperature of the air passing through the hygrometer 31, which measures the air upstream of the humidity conditioning space 50 and passing through the humidity conditioning material 10. This temperature-controlled air flows into the humidity conditioning space 50. This suppresses temperature fluctuations in the humidity conditioning space 50. Furthermore, the arithmetic unit 40 determines the temperature of the second temperature control element 22 based on the temperature and humidity obtained from the hygrometer 31 measuring the air passing through the humidity conditioning material 10 and from the hygrometer 31 located within the humidity conditioning space 50.

[0059] Figure 6 This is a graph showing the changes in temperature, humidity, and absolute humidity over time within a humidity-controlled space 50 when a humidity-controlled material 10 at 50% RH is cooled. Figure 7 This is a graph showing the changes in temperature, humidity, and absolute humidity over time within a humidity-controlled space 50 when a 50% RH humidity-controlled material 10 is heated. Figure 8 This is a graph showing the changes in temperature, humidity, and absolute humidity over time within a humidity-controlled space 50 when a 90% RH humidity-controlled material 10 is cooled.

[0060] Figure 6 ,exist Figure 7 and Figure 8 In this process, the humidity-regulating material 10 is filled inside the column. Additionally, air is circulated through the humidity-regulating material 10 and the humidity-regulating space 50 via a fan 60. Furthermore, a temperature and humidity meter is installed inside the humidity-regulating space 50, at the column outlet, and around (outside) the humidity-regulating space 50. The humidity-regulating material 10 is in bead-like (granular) form.

[0061] like Figure 6 As shown, when the humidity-regulating material 10 is cooled and air is circulated using 50% RH, the temperature inside and around the humidity-regulating space 50 remains constant or changes little, but the humidity inside the humidity-regulating space 50 decreases by approximately 15% RH over time. On the other hand, the humidity at the column outlet remains constant, that is, it can be controlled to approximately 15% RH. Furthermore, the absolute humidity inside the humidity-regulating space 50 and at the column outlet also decreases over time. If the temperature inside and around the humidity-regulating space 50 is the same, it can be controlled to 29% RH.

[0062] like Figure 7As shown, when the humidity-regulating material 10 is heated to 50% RH and air is circulated, the temperature inside and around the humidity-regulating space 50 remains constant or changes little, but the humidity inside the humidity-regulating space 50 increases by about 20% RH over time. On the other hand, the humidity at the column outlet remains constant, that is, it can be controlled at about 20% RH. In addition, the absolute humidity inside the humidity-regulating space 50 and at the column outlet also increases over time. If the temperature inside and around the humidity-regulating space 50 is the same, it can be controlled at 83% RH.

[0063] like Figure 8 As shown, when the humidity-regulating material 10 is used with 90% RH and cooled to circulate air, the temperature inside and around the humidity-regulating space 50 shows a constant or slightly varying value, but the humidity inside the humidity-regulating space 50 decreases by approximately 25% RH over time. On the other hand, the humidity at the column outlet remains constant, that is, it can be controlled to approximately 25% RH. Furthermore, the absolute humidity inside the humidity-regulating space 50 and at the column outlet also decreases over time. If the temperature inside and around the humidity-regulating space 50 is consistent, it can be controlled to 45% RH.

[0064] according to Figure 6 and Figure 7 As a result, the humidity control material 10 achieved a temperature control range of -7.6 to 11.6°C and a humidity control range of 32 to 63% RH at 50% RH and an ambient temperature of 17°C. If the temperature inside the humidity control space 50 is the same as the ambient temperature, the humidity control range can be achieved within the range of 29 to 83% RH.

[0065] In addition, according to Figure 8 As a result, the humidity control material 10 achieved a temperature control of -10.3°C at 90% RH and an ambient temperature of 16°C, with humidity control reaching 50~75% RH. If the temperature inside the humidity control space 50 is the same as the ambient temperature, the humidity control can be achieved within the range of 45~90% RH.

[0066] In addition to the materials mentioned above, the moisture conditioning material 10 is preferably a material with a fast moisture absorption and release rate, a material with no lag during moisture absorption and release, a material with a steep inclination of the adsorption isotherm, and a material with a large adsorption capacity per unit weight.

[0067] Figure 9 This is a graph showing the relative humidity and moisture absorption rate of the various types of humidity-regulating materials 10. For example... Figure 9 As shown, the moisture absorption rate for relative humidity is highest for humidity-regulating beads formed into beads, followed by humidity-regulating powder formed into powder. Additionally, humidity-regulating sheets, silica gel A, and silica gel B formed into sheets also absorb moisture from the relative humidity.

[0068] Figure 10This is a schematic diagram of the humidity control device 200 according to the second embodiment. In the humidity control device 100 of the first embodiment, air from the humidity control space 50 is supplied to the humidity control material 10, and the humidity control material 10 uses air from the humidity control space 50. However, in the humidity control device 200 of the second embodiment, as... Figure 10 As shown, the air inside the dehumidification space 50 is exhausted to the air outside the dehumidification material 10. In addition, the dehumidification material 10 uses the outside air outside the dehumidification space 50. Due to the humidity of the outside air, the moisture content of the dehumidification material 10 may change significantly. However, in this case, the dehumidification material 10 can be replaced with a new dehumidification material, or the dehumidification material 10 can be regenerated by using outside air.

[0069] Figure 11 This is a schematic diagram of the humidity control device 300 according to the third embodiment. Figure 11 As shown, the humidity control device 300 of the third embodiment includes a three-way valve 70 and a thermometer and hygrometer 32 upstream of the humidity control material 10. In the humidity control device 300 of the third embodiment, air from the humidity control space 50 is discharged outside the humidity control material 10, and the humidity control material 10 uses outside air from the humidity control space 50.

[0070] A three-way valve 70 is positioned upstream of the humidity-controlled space 50 and downstream of a hygrometer 31, which measures the air flowing through the humidity-controlled material 10. The hygrometer 31, which measures the air flowing through the humidity-controlled material 10 upstream of it, measures the temperature and humidity of the air flowing into the humidity-controlled material 10. The three-way valve 70 utilizes valves such as those used in other applications.

[0071] The three-way valve 70 is used to switch the flow path of the saturated humidity-regulating material 10, which is then regenerated by releasing the absorbed moisture through heating or other means. The three-way valve 70 switches during temperature-controlled regeneration of the humidity-regulating material 10 to discharge air passing through the humidity-regulating material 10 out of the humidity-regulating space 50. That is, during humidity control, air is supplied from the humidity-regulating material 10 into the humidity-regulating space 50, but during the regeneration of the humidity-regulating material 10, air is supplied from the humidity-regulating material 10 out of the humidity-regulating space 50. Regarding the regeneration of the humidity-regulating material 10, when the equilibrium humidity is low, the humidity-regulating material 10 is cooled, reducing the absolute humidity of the air flowing into the humidity-regulating material 10 (air upstream of the humidity-regulating material 10) and the air passing through the humidity-regulating material 10 (air downstream of the humidity-regulating material 10), thereby restoring the equilibrium humidity. When the equilibrium humidity is high, heating can lower the equilibrium humidity.

[0072] Figure 12This is a schematic diagram of the humidity control device 400 according to the fourth embodiment. In the humidity control device 300 of the third embodiment, air from the humidity control space 50 is discharged to components other than the humidity control material 10, and the humidity control material 10 uses external air from outside the humidity control space 50. However, the humidity control device 400 of the fourth embodiment... Figure 12 As shown, air from the humidity-conditioning space 50 is supplied to the humidity-conditioning material 10, and the humidity-conditioning material 10 uses the air from the humidity-conditioning space 50. A three-way valve (first three-way valve 70) is provided during the supply of air from the humidity-conditioning material 10 to the humidity-conditioning space 50, and a separate three-way valve (second three-way valve 71) is also provided during the supply of air from the humidity-conditioning space 50 to the humidity-conditioning material 10.

[0073] The humidity control device 400 of the fourth embodiment is effective when it is easier to control humidity by taking in air from outside the humidity control space 50 than by taking in air from the humidity control space 50.

[0074] Figure 13 This is a schematic diagram of the humidity control device 500 according to the fifth embodiment. (As shown) Figure 13 As shown, the humidity regulating device 500 of the fifth embodiment has a first humidity regulating material 10a and a second humidity regulating material 10b, so that air passing through the first humidity regulating material 10a and the second humidity regulating material 10b flows into the humidity regulating space 50.

[0075] The humidity control device 500 of the fifth embodiment uses a first humidity control material 10a and a second humidity control material 10b as multiple humidity control materials. Furthermore, the humidity control device 500 of the fifth embodiment includes temperature and humidity meters 32 and 34 for measuring the air before it passes through the first humidity control material 10a and the second humidity control material 10b, temperature and humidity meters 31 and 33 for measuring the air after it passes through, and a temperature and humidity meter 30 for measuring the temperature and humidity within the humidity control space 50. The arithmetic unit 40 determines the temperature of each temperature control element installed on the first humidity control material 10a and the second humidity control material 10b based on the temperature and humidity readings from these temperature and humidity meters 30, 31, 32, 33, and 34.

[0076] Furthermore, the humidity control device 500 of the fifth embodiment is equipped with multiple three-way valves 70, 72, 74, and 76 during the supply of air from the first humidity control material 10a and the second humidity control material 10b to the humidity control space 50. Moreover, the humidity control device 500 of the fifth embodiment is equipped with multiple independent three-way valves 71, 73, and 75 during the supply of air from the humidity control space 50 to the first humidity control material 10a and the second humidity control material 10b.

[0077] By setting multiple humidity-regulating materials 10 (first humidity-regulating material 10a and second humidity-regulating material 10b) and multiple three-way valves 70, 71, 72, 73, 74, 75, and 76, humidity control can be performed using the second humidity-regulating material 10b during the saturation regeneration of the first humidity-regulating material 10a.

[0078] In addition, fans 60 and 61 are respectively provided upstream of the first humidity-regulating material 10a and the second humidity-regulating material 10b.

[0079] Alternatively, the first humidity-regulating material 10a and the second humidity-regulating material 10b can be made of materials with different temperature and humidity zones. In order to achieve different temperature and humidity zones, the first humidity-regulating material 10a and the second humidity-regulating material 10b can be made of different materials.

[0080] For example, the first humidity-regulating material 10a uses a high humidity zone, and the second humidity-regulating material 10b uses a low humidity zone. As a result, the range of variation from room temperature is reduced, and therefore the energy required for temperature control is reduced.

[0081] In summary, the humidity control devices 100, 200, 300, 400, 400, and 500 disclosed herein can easily control humidity.

[0082] Furthermore, while the various embodiments and examples of this disclosure have been described in detail above, those skilled in the art will readily understand that many modifications can be made without substantially departing from the new aspects and effects of this disclosure. Therefore, all such modifications should be included within the scope of this disclosure.

[0083] For example, at least once in the specification or drawings, a term described together with a different term that is more general or synonymous may be replaced with a different term at any point in the specification or drawings. Furthermore, the configuration and operation of the device are not limited to the descriptions of the various embodiments and examples of this disclosure, and various modifications can be implemented.
