[0031] The details of the embodiments of the present disclosure are described with reference to the accompanying drawings. In the following drawings, the same or corresponding parts are marked with the same reference numerals, and repeated descriptions are not repeated. The following embodiments can also be appropriately combined and applied. Implementation method 1.

[0032] The carbon dioxide recovery device according to Embodiment 1 will be described. The carbon dioxide recovery device according to Embodiment 1 is assumed to be a carbon dioxide recovery device 100A.

[0033] (Structure of Carbon Dioxide Recovery Device 100A)

[0034] Next, the structure of the carbon dioxide recovery device 100A will be described.

[0035] Figure 1 It is a front view of the carbon dioxide recovery device 100A. Figure 2 It is a side view of the carbon dioxide recovery device 100A. Figure 3 It is a perspective view of the adsorbent 30 included in the carbon dioxide recovery device 100A. Figure 4 yes Figure 1 Cross-sectional view at IV-IV in FIG. Figure 5 is from Figure 1 The direction of the arrow V in the figure is observed. Figures 1 to 5 As shown, the carbon dioxide recovery device 100A includes a plurality of guide rails 10 , a clamp 20 , and an adsorbent 30 .

[0036] The guide rail 10 includes a first side plate 11 , a second side plate 12 , a plurality of shafts 13 , and a plurality of rollers 14 .

[0037] The first side plate 11 and the second side plate 12 are arranged to face each other at a distance in a second direction DR2 perpendicular to the first direction DR1. The first direction DR1 is a vertical direction (vertical direction). The second direction DR2 is a direction perpendicular to the first direction DR1. The third direction DR3 is a direction perpendicular to the first direction DR1 and the second direction DR2.

[0038] exist Figure 1 In the example shown, the number of the plurality of guide rails 10 is four. Figure 1 The four guide rails 10 shown are guide rails 10A, 10B, 10C, and 10D. In the guide rails 10A and 10C, the first side plate 11 and the second side plate 12 are connected at one end ( Figure 1 The right end in the third direction DR3) is larger than the other end in the third direction DR3 ( Figure 1In the guide rail 10B and the guide rail 10D, the first side plate 11 and the second side plate 12 are inclined so that the other end in the third direction DR3 is more upward than the one end in the third direction DR3.

[0039] The other end of the guide rail 10B in the third direction DR3 is closer to the other side in the third direction DR3 than the other end of the guide rail 10A in the third direction DR3. One end of the guide rail 10C in the third direction DR3 is closer to one side in the third direction DR3 than one end of the guide rail 10B in the third direction DR3. The other end of the guide rail 10D in the third direction DR3 is closer to the other side in the third direction DR3 than the other end of the guide rail 10C in the third direction DR3.

[0040] The shaft 13 is rotatably supported at one end by the first side plate 11 and rotatably supported at the other end by the second side plate 12. The plurality of shafts 13 are arranged in a row along the extending direction of the first side plate 11 (the second side plate 12). A roller 14 is arranged on the outer peripheral surface of the shaft 13. The roller 14 rotates around the central axis of the shaft 13.

[0041] The clamp 20 is plate-shaped. The clamp 20 is disposed on the guide rail 10. More specifically, the clamp 20 is disposed on the plurality of rollers 14 between the first side plate 11 and the second side plate 12. The clamp 20 is rotatable on the guide rail 10 (roller 14).

[0042] The clamp 20 has a first surface 20a and a second surface 20b. The first surface 20a and the second surface 20b are end surfaces of the clamp 20 in the thickness direction. The first surface 20a is a surface in contact with the roller 14. The second surface 20b is the opposite surface of the first surface 20a. The upper end of the first side plate 11 and the upper end of the second side plate 12 preferably protrude more than the second surface 20b. When viewed from a direction orthogonal to the second surface 20b, the clamp 20 is, for example, circular. However, the planar shape of the clamp 20 is not limited thereto.

[0043] The adsorbent 30 has a skeleton 31 and an adsorbent 32 (not shown). The skeleton 31 has, for example, a honeycomb structure. The adsorbent 32 is formed of a material that can adsorb carbon dioxide. The adsorbent 32 carries, for example, amines, zeolites, silica gel, diatomaceous earth, alumina, activated carbon, and the like. The adsorbent 32 is attached to the inner wall surface and the outer wall surface of the skeleton 31. Therefore, regardless of the direction of the airflow toward the adsorbent 30, the adsorbent 30 can adsorb the carbon dioxide contained in the airflow. The adsorbent 30 is arranged on the fixture 20. More specifically, the adsorbent 30 is arranged on the second surface 20b.

[0044] The adsorbent 30 moves downward together with the clamp 20 through the plurality of guide rails 10. More specifically, the clamp 20 and the adsorbent 30 move on the guide rail 10A from one end side on the third direction DR3 of the guide rail 10A toward the other end side on the third direction DR3 under the action of gravity. The clamp 20 and the adsorbent 30 that have reached the other end side on the third direction DR3 of the guide rail 10A fall onto the guide rail 10B.

[0045] Similarly, the jig 20 and the adsorption body 30 move on the guide rail 10B from the other end side in the third direction DR3 of the guide rail 10B toward one end side in the third direction DR3 and fall on the guide rail 10C. By repeating the above operation, the jig 20 and the adsorption body 30 move downward.

[0046] The carbon dioxide recovery device 100A may further include a conveying unit 40. The conveying unit 40 moves the clamp 20 and the adsorbent 30 that have moved downward through the plurality of guide rails 10 upward. More specifically, the conveying unit 40 moves the clamp 20 and the adsorbent 30 that have reached one end of the third direction DR3 of the guide rail 10 (guide rail 10D) located at the bottom upward. As a result, the clamp 20 and the adsorbent 30 return to the guide rail 10 (guide rail 10A) located at the top.

[0047] The conveying unit 40 includes, for example, a conveying chamber 41, a wire 42, and a driving unit 43. The conveying chamber 41 contains the clamp 20 and the adsorbent 30. The wire 42 is connected to the conveying chamber 41 at one end and to the driving unit 43 at the other end. The driving unit 43 is, for example, a motor. The driving unit 43 moves the conveying chamber 41 upward by winding the wire 42, and accordingly, the clamp 20 and the adsorbent 30 also move upward.

[0048] The carbon dioxide recovery device 100A also has a frame 50. The internal space of the frame 50 has a first space SP1 and a second space SP2. A plurality of guide rails 10 are arranged in the first space SP1. Therefore, the clamp 20 and the adsorber 30 move downward in the first space SP1. More specifically, the driving unit 43 moves the conveying chamber 41 upward in the second space SP2 by winding the wire 42. In this way, the conveying unit 40 passes through the second space SP2 to move the clamp 20 and the adsorber 30 upward.

[0049] The frame 50 is installed, for example, in the outdoor unit 53 of the air conditioner. The frame 50 has openings on the front surface (the surface of the frame 50 located on the opposite side of the outdoor unit 53 of the air conditioner) and the back surface (the surface of the frame 50 located on the side of the outdoor unit 53 of the air conditioner). A fan (not shown) is arranged in the outdoor unit 53 of the air conditioner, and the air flow flows in the first space SP1, for example, along the second direction DR2 by the rotation of the fan. That is, the air flow is introduced into the frame 50 (first space SP1) from the opening located on the front surface of the frame 50, and is discharged from the opening located on the back surface of the frame 50. The air flow flowing in the first space SP1 is discharged to the outside of the outdoor unit 53 of the air conditioner after passing through the inside of the outdoor unit 53 of the air conditioner from the exhaust port 52 of the outdoor unit 53 of the air conditioner. However, the flow direction of the air flow in the first space SP1 is not limited to this. A plurality of ventilation holes 51 may also be formed in the frame 50. The ventilation holes 51 penetrate the frame 50 to connect the second space SP2 with the outside of the frame 50. The airflow is also introduced into the second space SP2 through the ventilation holes 51. When the ventilation holes 51 are formed, the adsorbent 30 is transported in the second space SP2 and is also exposed to carbon dioxide. The airflow is a flow of gas containing carbon dioxide.

[0050] (Effects of the Carbon Dioxide Recovery Device 100A)

[0051] Next, the effects of the carbon dioxide recovery device 100A will be described.

[0052] As described above, since there is airflow in the first space SP1, the airflow collides with the adsorbent 30 while the adsorbent 30 moves downward through the guide rail 10, and the adsorbent 30 adsorbs carbon dioxide in the airflow. In the case where the airflow collides with the adsorbent 30 only from one direction, it is difficult for the portion of the adsorbent 30 located on the downstream side of the airflow to adsorb carbon dioxide, and the recovery efficiency of carbon dioxide is reduced. However, in the carbon dioxide recovery device 100A, since the clamp 20 can be rotatably arranged on the guide rail 10, different portions of the adsorbent 30 face the upstream side of the airflow while the adsorbent 30 moves downward. Therefore, according to the carbon dioxide recovery device 100A, the recovery efficiency of carbon dioxide can be improved.

[0053] In the carbon dioxide recovery device 100A, the upper end of the first side plate 11 and the upper end of the second side plate 12 protrude from the second surface 20b. Therefore, the movement of the clamp 20 in the direction orthogonal to the moving direction of the clamp 20 is restricted by the first side plate 11 and the second side plate 12. That is, the clamp 20 is prevented from falling off the guide rail 10. As a result, in the carbon dioxide recovery device 100A, the mesh member covering the guide rail 10 is no longer required, and the ventilation resistance when the airflow flows in the first space SP1 can be reduced.

[0054] In the case where the carbon dioxide recovery device 100A has a conveying part 40, the clamp 20 and the adsorber 30 that move downward through the guide rail 10 return to the guide rail 10 located at the top again. Therefore, in the case where the carbon dioxide recovery device 100A has a conveying part 40, the adsorber 30 is repeatedly exposed to the airflow, further improving the recovery efficiency of carbon dioxide. When the ventilation holes 51 are formed in the frame 50, the adsorber 30 is also exposed to the airflow while moving upward and returning to the guide rail 10 located at the top. Therefore, when the ventilation holes 51 are formed in the frame 50, the recovery efficiency of carbon dioxide is further improved. Implementation method 2.

[0055] The carbon dioxide recovery apparatus according to Embodiment 2 will be described. The carbon dioxide recovery apparatus according to Embodiment 2 is referred to as a carbon dioxide recovery apparatus 100B. Here, points different from the carbon dioxide recovery apparatus 100A will be mainly described, and duplicate descriptions will not be repeated.

[0056] (Structure of Carbon Dioxide Recovery Device 100B)

[0057] Next, the structure of the carbon dioxide recovery device 100B will be described.

[0058] Figure 6 It is a front view of the carbon dioxide recovery device 100B. Figure 7 is from Figure 6 The direction of arrow VII in the figure is observed. Figure 7 In the figure, the adsorbent 30 is omitted. Figure 6 as well as Figure 7 As shown, the carbon dioxide recovery device 100B includes a plurality of guide rails 10, a jig 20, an adsorbent 30, a conveyor 40, and a frame 50. In this respect, the structure of the carbon dioxide recovery device 100B is the same as that of the carbon dioxide recovery device 100A.

[0059] In the carbon dioxide recovery device 100B, a plurality of ventilation holes 21 are formed in the jig 20. The ventilation holes 21 penetrate the jig 20 in the thickness direction. In these respects, the structure of the carbon dioxide recovery device 100B is different from that of the carbon dioxide recovery device 100A.

[0060] (Effects of the Carbon Dioxide Recovery Device 100B)

[0061] Next, the effects of the carbon dioxide recovery device 100B will be described.

[0062] In the carbon dioxide recovery device 100B, since the vent holes 21 of the clamp 20 are formed, the airflow can pass through the vent holes 21, and the ventilation resistance becomes small. In addition, the carbon dioxide contained in the airflow passing through the vent holes 21 is also adsorbed by the adsorbent 30, thereby further improving the recovery efficiency of carbon dioxide. Implementation method 3.

[0063] The carbon dioxide recovery apparatus according to Embodiment 3 will be described. The carbon dioxide recovery apparatus according to Embodiment 3 is referred to as a carbon dioxide recovery apparatus 100C. Here, points different from the carbon dioxide recovery apparatus 100A will be mainly described, and duplicate descriptions will not be repeated.

[0064] (Structure of Carbon Dioxide Recovery Device 100C)

[0065] Next, the structure of the carbon dioxide recovery device 100C will be described.

[0066] Figure 8 It is a front view of the carbon dioxide recovery device 100C. Fig. 9 is from Figure 8 The direction of the arrow IX in the figure is observed. Figure 8 as well as Fig. 9 As shown, the carbon dioxide recovery device 100C includes a plurality of guide rails 10, jigs 20, adsorbents 30, a conveyor 40, and a frame 50. In this respect, the structure of the carbon dioxide recovery device 100C is the same as that of the carbon dioxide recovery device 100A.

[0067] In the carbon dioxide recovery apparatus 100C, the friction resistance between the first side plate 11 and the clamp 20 is different from the friction resistance between the second side plate 12 and the clamp 20. In this respect, the structure of the carbon dioxide recovery apparatus 100C is different from that of the carbon dioxide recovery apparatus 100A.

[0068] The first side plate 11 is formed of, for example, a material different from that of the second side plate 12. The surface roughness of the surface of the first side plate 11 in contact with the clamp 20 may be different from the surface roughness of the surface of the second side plate 12 in contact with the clamp 20. Either the surface of the first side plate 11 in contact with the clamp 20 or the surface of the second side plate 12 in contact with the clamp 20 may be subjected to a surface treatment that increases or decreases the friction with the clamp 20. That is, the structure that makes the friction resistance between the first side plate 11 and the clamp 20 different from the friction resistance between the second side plate 12 and the clamp 20 is not particularly limited.

[0069] (Effects of the Carbon Dioxide Recovery Device 100C)

[0070] Next, the effects of the carbon dioxide recovery device 100C will be described.

[0071] In the carbon dioxide recovery device 100C, the friction resistance between the first side plate 11 and the clamp 20 is different from the friction resistance between the second side plate 12 and the clamp 20. Therefore, the friction force F1 (refer to Fig. 9 ) and the friction force F2 (refer to Fig. 9 ) creates an imbalance between them.

[0072] The uneven friction force promotes the rotation of the clamp 20 on the guide rail 10 (see Fig. 9 As a result, in the carbon dioxide recovery device 100C, various parts of the adsorbent 30 are easily oriented toward the upstream side of the airflow flowing in the first space SP1, and the carbon dioxide recovery efficiency is further improved. Implementation method 4.

[0073] A carbon dioxide recovery device according to Embodiment 4 will be described. The carbon dioxide recovery device according to Embodiment 4 is referred to as a carbon dioxide recovery device 100D. Here, points different from the carbon dioxide recovery device 100A will be mainly described, and duplicate descriptions will not be repeated.

[0074] (Structure of carbon dioxide recovery device 100D)

[0075] Next, the structure of the carbon dioxide recovery device 100D will be described.

[0076] Fig.10 It is a front view of the carbon dioxide recovery device 100D. Fig.11 yes Fig.10 Cross-sectional view at XI-XI in FIG. Fig.12 is from Fig.11 The direction of arrow XII in the figure is observed. Figures 10 to 12 As shown, the carbon dioxide recovery device 100D includes a plurality of guide rails 10, jigs 20, adsorbents 30, a conveyor 40, and a frame 50. In this respect, the structure of the carbon dioxide recovery device 100D is the same as that of the carbon dioxide recovery device 100A.

[0077] In the carbon dioxide recovery device 100D, the first side plate 11 and the second side plate 12 face each other at a distance in the fourth direction DR4. The fourth direction DR4 is orthogonal to the third direction DR3, but is not orthogonal to the first direction DR1 and the second direction DR2 (inclined relative to the first direction DR1 and the second direction DR2). In other words, from another point of view, the first side plate 11 faces the second side plate 12 at a distance and is above the second side plate 12. In these aspects, the structure of the carbon dioxide recovery device 100D is different from that of the carbon dioxide recovery device 100A.

[0078] (Effects of the CO2 Recovery Device 100D)

[0079] Next, the effects of the carbon dioxide recovery device 100D will be described.

[0080] In the carbon dioxide recovery device 100D, since the first side plate 11 is located above the second side plate 12, the friction force F1 (see Fig.12 ) is greater than the friction force F2 (refer to Fig.12 )Small.

[0081] The uneven friction force promotes the rotation of the clamp 20 on the guide rail 10 (see Fig.12 As a result, in the carbon dioxide recovery device 100D, various parts of the adsorber 30 are easily oriented toward the upstream side of the airflow flowing in the first space SP1, and the carbon dioxide recovery efficiency is further improved. Implementation method 5.

[0082] The carbon dioxide recovery apparatus according to Embodiment 5 will be described. The carbon dioxide recovery apparatus according to Embodiment 5 is referred to as a carbon dioxide recovery apparatus 100E. Here, points different from the carbon dioxide recovery apparatus 100A will be mainly described, and duplicate descriptions will not be repeated.

[0083] (Structure of the carbon dioxide recovery device 100E)

[0084] Next, the structure of the carbon dioxide recovery device 100E will be described.

[0085] The carbon dioxide recovery device 100E includes a plurality of guide rails 10, jigs 20, adsorbents 30, a conveyor 40, and a frame 50. In this respect, the structure of the carbon dioxide recovery device 100E is the same as that of the carbon dioxide recovery device 100A.

[0086] Fig.13 It is an exploded perspective view of the adsorbent 30 included in the carbon dioxide recovery apparatus 100E. Fig.14 FIG. 1 is a perspective view of the adsorbent 30 included in the carbon dioxide recovery device 100E. Fig.13 as well as Fig.14 As shown, in the carbon dioxide recovery device 100E, the frame 31 has a plurality of flat plate members 31a and a plurality of corrugated plate members 31b. The flat plate members 31a and the corrugated plate members 31b are alternately stacked. In other words, a corrugated plate member 31b is arranged between two adjacent flat plate members 31a, and a flat plate member 31a is arranged between two adjacent corrugated plate members 31b.

[0087] The corrugated plate member 31b has a plurality of grooves 31ba. The grooves 31ba extend in a straight line. The plurality of grooves 31ba are arranged in a direction perpendicular to the extending direction of the grooves 31ba. The extending direction of the grooves 31ba on one side of two adjacent corrugated plate members 31b is perpendicular to the extending direction of the grooves 31ba on the other side of two adjacent corrugated plate members 31b. It should be noted that, although not shown in the figure, an adsorbent 32 is attached to the surface of the skeleton 31.

[0088] (Effects of the CO2 Recovery Device 100E)

[0089] Next, the effects of the carbon dioxide recovery device 100E will be described.

[0090] In the carbon dioxide recovery device 100E, the frame 31 is formed by alternately stacking the flat plate members 31a and the corrugated plate members 31b, so that no matter from which direction the airflow collides with the adsorbent 30, the airflow enters the interior of the frame 31. Therefore, according to the carbon dioxide recovery device 100E, the recovery efficiency of carbon dioxide is further improved. Implementation method 6.

[0091] The carbon dioxide recovery apparatus according to Embodiment 6 will be described. The carbon dioxide recovery apparatus according to Embodiment 6 is referred to as a carbon dioxide recovery apparatus 100F. Here, points different from the carbon dioxide recovery apparatus 100A will be mainly described, and duplicate descriptions will not be repeated.

[0092] (Structure of carbon dioxide recovery device 100F)

[0093] Next, the structure of the carbon dioxide recovery device 100F will be described.

[0094] The carbon dioxide recovery device 100F includes a plurality of guide rails 10, jigs 20, adsorbents 30, a conveyor 40, and a frame 50. In this respect, the structure of the carbon dioxide recovery device 100F is the same as that of the carbon dioxide recovery device 100A.

[0095] Fig.15 FIG. 1 is a perspective view of the adsorbent 30 included in the carbon dioxide recovery device 100F. Fig.15 As shown, in the carbon dioxide recovery device 100F, the adsorbent 30 has a plurality of adsorbents 32 and a container 33. In the carbon dioxide recovery device 100F, the adsorbent 32 is in a bead shape. The container 33 is in a mesh shape. The adsorbent 32 is accommodated in the container 33. In these aspects, the structure of the carbon dioxide recovery device 100F is different from the structure of the carbon dioxide recovery device 100A.

[0096] (Effect of the Carbon Dioxide Recovery Device 100F)

[0097] Next, the effects of the carbon dioxide recovery device 100F will be described.

[0098] In the carbon dioxide recovery device 100F, since the container 33 is in a mesh shape, no matter from which direction the airflow collides with the adsorbent 30, the airflow enters the interior of the container 33, and the carbon dioxide contained in the airflow is adsorbed by the bead-shaped adsorbent 32. Therefore, according to the carbon dioxide recovery device 100F, the recovery efficiency of carbon dioxide is further improved. Implementation method 7.

[0099] The carbon dioxide recovery apparatus according to Embodiment 7 will be described. The carbon dioxide recovery apparatus according to Embodiment 7 is referred to as a carbon dioxide recovery apparatus 100G. Here, points different from the carbon dioxide recovery apparatus 100A will be mainly described, and duplicate descriptions will not be repeated.

[0100] (Structure of carbon dioxide recovery device 100G)

[0101] Next, the structure of the carbon dioxide recovery device 100G will be described.

[0102] Fig.16 It is a front view of the carbon dioxide recovery device 100G. Fig.17 is from Fig.16 The direction of arrow XVII is observed in Fig. Fig.16 as well as Fig.17 As shown, the carbon dioxide recovery device 100G includes a plurality of guide rails 10, jigs 20, adsorbents 30, a conveyor 40, and a frame 50. In this respect, the structure of the carbon dioxide recovery device 100G is the same as that of the carbon dioxide recovery device 100A.

[0103] In the carbon dioxide recovery apparatus 100G, the guide rail 10 is configured to vibrate the jig 20 and the adsorbent 30 while moving the jig 20 and the adsorbent 30 downward. In this respect, the structure of the carbon dioxide recovery apparatus 100G is different from that of the carbon dioxide recovery apparatus 100A.

[0104] In the carbon dioxide recovery device 100G, the interval between two adjacent shafts 13 is longer than that in the carbon dioxide recovery device 100A. Therefore, in the carbon dioxide recovery device 100G, the clamp 20 and the adsorbent 30 are easily vibrated when they move downward on the guide rail 10. In addition, in the carbon dioxide recovery device 100G, it can be configured so that a part of the plurality of shafts 13 protrudes from the remaining part of the plurality of shafts 13 arranged in a row. Therefore, when the clamp 20 and the adsorbent 30 pass over a part of the plurality of shafts located at the protruding position, vibration is easily applied. That is, in the carbon dioxide recovery device 100G, the structure attached to the clamp 20 and the adsorbent 30 is not particularly limited on the guide rail 10.

[0105] (Effect of the carbon dioxide recovery device 100G)

[0106] Next, the effects of the carbon dioxide recovery device 100G will be described.

[0107] In the carbon dioxide recovery device 100G, vibration is applied to the clamp 20 and the adsorbent 30 while the clamp 20 and the adsorbent 30 are moving downward through the guide rail 10, thereby promoting the rotation of the clamp 20 and the adsorbent 30 on the guide rail 10. Therefore, according to the carbon dioxide recovery device 100G, the recovery efficiency of carbon dioxide is further improved. Implementation method 8.

[0108] The carbon dioxide recovery apparatus according to Embodiment 8 will be described. The carbon dioxide recovery apparatus according to Embodiment 8 is referred to as a carbon dioxide recovery apparatus 100H. Here, points different from the carbon dioxide recovery apparatus 100A will be mainly described, and duplicate descriptions will not be repeated.

[0109] (Structure of the carbon dioxide recovery device 100H)

[0110] Next, the structure of the carbon dioxide recovery device 100H will be described.

[0111] Fig.18 FIG. 1 is a front view of the carbon dioxide recovery device 100H. Fig.18 As shown, the carbon dioxide recovery device 100H has a plurality of guide rails 10, a clamp 20 and an adsorbent 30. The carbon dioxide recovery device 100H may further have a conveying unit 40. In this regard, the structure of the carbon dioxide recovery device 100H is common to the structure of the carbon dioxide recovery device 100A. The carbon dioxide recovery device 100H does not have a frame 50. In this regard, the structure of the carbon dioxide recovery device 100H is different from the structure of the carbon dioxide recovery device 100A. It should be noted that in the carbon dioxide recovery device 100H, the plurality of guide rails 10 are installed, for example, on the outdoor unit 53 of the air conditioner.

[0112] (Effect of 100H of CO2 recovery device)

[0113] Next, the effects of the carbon dioxide recovery device 100H will be described.

[0114] Since the carbon dioxide recovery device 100H does not include the frame 50, the airflow containing carbon dioxide contacts the adsorbent 30 from all directions except the direction blocked by the guide rail 10. Therefore, according to the carbon dioxide recovery device 100H, carbon dioxide can be recovered efficiently.

[0115] The embodiments disclosed this time should be considered as illustrative in all aspects and not restrictive. The basic scope of the present disclosure is shown by the claims rather than the above embodiments, and is intended to include all modifications within the meaning and scope equivalent to the claims.
