[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding elements are designated by the same reference numerals, and for clarity of explanation, duplicate explanations will be omitted as necessary. Furthermore, in this specification, the numerical range indicated by "to" includes the numerical values ​​before and after it as the lower and upper limits.

[0022] <Embodiment 1> Embodiment 1 is an embodiment in which glass according to the present disclosure is applied to laminated glass with a light control function. Fig. 1 is a schematic front view showing an example configuration of glass 100 according to embodiment 1. As shown in Fig. 1, glass 100 includes glass 110, a harness 120, a noise suppression sheet 130, and a light control film 140. Glass 100 is suitable for vehicle roof glass.

[0023] The glass 110 is a laminated glass formed by stacking a plurality of glass sheets with an interlayer film sandwiched between them. FIG. 4 is a schematic cross-sectional view showing an example configuration of the glass 100. As shown in FIG. 4, the glass 110 is, for example, a laminated glass formed by sandwiching an interlayer film 150 between two glass sheets 111 and 112. The type of glass constituting the glass sheets 111 and 112 is not particularly limited. The glass sheets 111 and 112 may be inorganic glass such as soda-lime silicate glass, aluminosilicate glass, alkali-free glass, or borosilicate glass, or organic glass such as polycarbonate glass or acrylic resin glass. The glass 110 may be colorless glass such as clear glass, or colored glass such as privacy glass. The glass sheets 111 and 112 may also be tempered glass such as physically tempered glass or chemically tempered glass. The tempered glass may be, for example, untempered glass with a compressive stress layer formed on the surface.

[0024] The thickness of the plate glasses 111 and 112 is preferably 1.0 mm or more, more preferably 1.5 mm or more, and even more preferably 2.0 mm or more. The thickness of the plate glasses 111 and 112 is preferably 8.0 mm or less, more preferably 6.0 mm or less, still more preferably 4.0 mm or less, particularly preferably 3.0 mm or less, and particularly more preferably 2.5 mm or less. The thicknesses of the plate glasses 111 and 112 may be the same or different from each other.

[0025] At least one of the main surfaces of the glass sheets 111 and 112 may be provided with a coating having various functions. For example, the glass sheets 111 and 112 may have a heat-reflecting film such as an infrared-reflecting film or an infrared-absorbing film, a Low-E (Low Emissivity) film, or a water-repellent film on the surface facing the interior of the room when installed. The infrared-reflecting film is a film that selectively reflects infrared rays. The Low-E film ensures thermal insulation by suppressing heat transfer due to radiation. The water-repellent film is a film that has high water repellency. The glass sheets 111 and 112 may also have a self-cleaning film on the surface facing the exterior of the room when installed. The self-cleaning film is a film that suppresses the adhesion of organic and inorganic substances to the surface, or a film that allows the adhesion of organic and inorganic substances to be easily removed by cleaning, such as wiping, even if they do adhere to the surface.

[0026] The interlayer 150 is made of, for example, a transparent resin. Examples of the resin that makes up the interlayer 150 include polyvinyl butyral (PVB), polyvinyl chloride, ethylene vinyl acetate (EVA), cycloolefin polymer, urethane resin, and polyvinylidene fluoride (PVDF). The thickness of the interlayer 150 is preferably 0.1 mm or more, more preferably 0.2 mm or more, even more preferably 0.3 mm or more, particularly preferably 0.5 mm or more, and particularly more preferably 0.7 mm or more. The thickness of the interlayer 150 is preferably 2.0 mm or less, more preferably 1.0 mm or less, and even more preferably 0.8 mm or less. The interlayer 150 may be colorless or colored. The interlayer 150 may be colored, for example, by being made of a resin containing a colorant such as a pigment.

[0027] In the configuration example shown in Fig. 4, a light control film 140 is sandwiched between two intermediate films 150. The light control film 140 is an example of a device that operates by an electrical signal, and has a light control function in which the transmittance state changes depending on the applied voltage. The light control film 140 may be made of a suspended particle device (SPD), a polymer dispersed liquid crystal (PDLC), a polymer network liquid crystal (PNLC), a guest-host liquid crystal (GHLC), a twisted nematic (TN) liquid crystal, a phase change (PC) liquid crystal, a super twisted nematic (STN) liquid crystal, an electrically controlled birefringence (ECB) liquid crystal, an optically compensated bend (OCB) liquid crystal, an in-place switching (IPS) liquid crystal, a vertical alignment (VA) liquid crystal, a fringe field switching (FFS) liquid crystal, a field-induced photo-reactive alignment (FPA) liquid crystal, an electrochromic element, an electrokinetic element, an organic electroluminescence (EL) element, an inorganic EL element, or the like.

[0028] As shown in FIG. 1 , the harness 120 is disposed in a position overlapping the glass 110 when the glass 110 is viewed in a plan view. In the example shown in FIG. 4 , the harness 120 is disposed so as to be sandwiched between two interlayer films 150. That is, the harness 120 is disposed so as to be sandwiched between two glass plates 111 and 112. As shown in FIG. 1 , the harness 120 is disposed, for example, at the edge of the glass 110 when the glass 110 is viewed in a plan view. The harness 120 is a transmission line connected to the light control film 140. As shown in FIGS. 1 and 4 , one end of the harness 120 is connected to the light control film 140. The other end of the harness 120 is connected to a power supply unit (not shown). Power is supplied to the light control film 140 from the power supply unit via the harness 120. The harness 120 may be selected appropriately depending on the characteristics of the electrical signal to be transmitted. When transmitting a high-frequency electrical signal, the harness 120 may be a harness with a coplanar structure. The harness 120 may also be a balanced line having at least two transmission lines for transmitting differential signals, or may be a combination of a coplanar structure, a balanced line, and a power line.

[0029] 2 and 3 , a configuration example in which the harness 120 has a coplanar structure will be described. As shown in FIG. 3 , the harness 120 includes a base film 124, conductors 125, and a cover film 126. The conductors 125 are made of a conductive material, such as copper foil. A plurality of conductors 125 are arranged along the extension direction of the harness 120. The conductors 125 are arranged to form linear gaps. The shaded areas in FIG. 2 represent the conductors 125. In the example shown in FIG. 2 , five conductors 125 are arranged to form four gaps extending along the extension direction of the harness 120. In this case, the second and fourth conductors from the left end of the five conductors 125 function as two transmission lines extending from one end to the other end. The thickness of the conductor 125 is preferably 3 μm or more, more preferably 8 μm or more, even more preferably 10 μm or more, particularly preferably 15 μm or more, and particularly more preferably 18 μm or more. The thickness of the conductor 125 is preferably 40 μm or less, more preferably 30 μm or less, and even more preferably 25 μm or less.

[0030] The base film 124 and the cover film 126 are elongated films made of an insulating material. The base film 124 and the cover film 126 are made of a resin such as polyimide or polyester. The thickness of the base film 124 and the cover film 126 is preferably 5 μm or more, more preferably 10 μm or more, even more preferably 15 μm or more, particularly preferably 20 μm or more, and particularly more preferably 25 μm or more. The thickness of the base film 124 and the cover film 126 is preferably 50 μm or less, more preferably 40 μm or less, and even more preferably 30 μm or less.

[0031] As shown in Fig. 3, the dimension of the harness 120 in the thickness direction is smaller than the dimension in the width direction, i.e., the direction perpendicular to the extension direction and thickness direction of the harness 120. In other words, the harness 120 shown in Figs. 2 and 3 has two main surfaces in a direction substantially parallel to the main surfaces of the glass 110. Note that "substantially" refers to a state in which the harness 120 appears to have the same shape and dimensions when viewed by a human.

[0032] As shown in FIG. 1 , a noise suppression sheet 130 is attached to at least a portion of the harness 120. Specifically, the noise suppression sheet 130 is attached to at least one of the two main surfaces of the harness 120. In other words, when the glass 100 is viewed in plan, the noise suppression sheet 130 is attached to at least one of the surface of the harness 120 that is closest to the driver and the surface opposite the closest surface. Hereinafter, when the noise suppression sheet 130 is attached to both of the two main surfaces of the harness 120, it may be referred to as "the noise suppression sheet 130 is attached to both sides of the harness 120." Furthermore, when the noise suppression sheet 130 is attached to only one of the two main surfaces of the harness 120, it may be referred to as "the noise suppression sheet 130 is attached to one side of the harness 120."

[0033] The noise suppression sheet 130 suppresses noise generated by the harness 120. The noise suppression sheet 130 may be, for example, a sheet made of resin containing magnetic powder, which converts noise into heat through the magnetic loss of the magnetic powder. The magnetic powder may be, for example, graphite powder. Examples of resins that make up the sheet include silicone resin and acrylic resin. The noise suppression sheet 130 may be a commercially available noise suppression sheet, and specific examples of commercially available products include MF, HF1, and HF2 manufactured by Riken Corporation.

[0034] The frequency band of noise to be suppressed can be adjusted by adjusting the way the noise suppression sheet 130 is attached. As will be described in detail later, attaching the noise suppression sheet 130 to both sides of the harness 120 suppresses noise in a lower frequency band compared to attaching it to only one side. Furthermore, increasing the dimension, i.e., length, of the noise suppression sheet 130 attached to the harness 120 in the extension direction can suppress noise in a lower frequency band compared to a shorter dimension. In other words, adjusting the length of the noise suppression sheet 130 can achieve a desired cutoff frequency. The length of the harness 120 is longer than the length of the noise suppression sheet 130. Therefore, when the length of the noise suppression sheet 130 is set to a length that can suppress noise in a desired frequency band, the length of the harness 120 is longer than the length of the noise suppression sheet 130 that achieves the desired cutoff frequency.

[0035] In the example shown in Fig. 4 , the plate glass 112 side is the interior of the vehicle, and the plate glass 111 side is the exterior of the vehicle. The body 160 shown in Fig. 4 is a component constituting the vehicle. The glass 100 is adhered to the body 160 using an adhesive member 170. In the example shown in Fig. 4 , the end of the harness 120 connected to the light control film 140 is sandwiched between the intermediate film 150, and the other end extends to the interior of the vehicle and is connected to a power supply unit (not shown). In the example shown in Fig. 4 , since the harness 120 and the noise suppression sheet 130 are sandwiched between the intermediate film 150, from the viewpoint of ease of manufacture, it is preferable that the total thickness of the harness 120 and the noise suppression sheet 130 be equal to or less than a predetermined value. For example, if the thickness of the intermediate film 150 is d, then the total thickness d of the harness 120 and the noise suppression sheet 130 is d. ｈ Then, d ｈ / d is preferably 1.00 or less, more preferably 0.63 or less, even more preferably 0.38 or less, and particularly preferably 0.25 or less.

[0036] Applying the noise suppression sheet 130 only to a portion of the harness 120 reduces the amount of noise suppression sheet 130 used compared to applying it to the entire harness 120. For example, as shown in FIG. 4 , the noise suppression sheet 130 may be applied only to a portion of the harness 120 sandwiched between the interlayer films 150 that is closer to the power supply portion. In other words, the noise suppression sheet 130 may be applied only to a portion closer to the entrance of the glass 110. Applying the noise suppression sheet 130 to the portion closer to the power supply portion as shown in FIG. 4 suppresses noise at the entrance of the glass 110. Therefore, noise generated between the light control film 140 and the body 160 and between the harness 120 and the body 160 can be effectively suppressed.

[0037] <Embodiment 2> In Embodiment 1, a case where a harness and a noise suppression sheet are sandwiched between glass sheets constituting a laminated glass has been described. However, the harness and the noise suppression sheet may be attached to the main surfaces of the glass sheets. In Embodiment 2, a case where a harness and a noise suppression sheet are attached to the main surfaces of the glass sheets will be described. Fig. 5 is a schematic front view showing an example of the configuration of a glass sheet 200 according to Embodiment 2. Fig. 6 is a partially enlarged cross-sectional view of the glass sheet 200 according to Embodiment 2.

[0038] The glass 200 differs from the glass 100 in that it includes a camera heater 240 instead of the light control film 140. Other configurations of the glass 200 are similar to those of the glass 100, and therefore will not be described as appropriate. The camera heater 240 is an example of a device that operates by an electrical signal and has a heater function that generates heat when powered. A film heater, for example, can be used as the camera heater 240. A camera (not shown) is attached to the glass 200, and the camera heater 240 is disposed near the camera's mounting position. The camera heater 240 prevents glass fogging by heating the glass near the mounting position, i.e., the location where the camera is mounted. Therefore, even in conditions where glass is prone to fogging, such as low outside temperatures, the camera can clearly capture images of the outside of the vehicle through the glass. This glass 200 is suitable for a windshield equipped with a camera for an ADAS (Advanced Driving Assistance System), etc.

[0039] In the example shown in Fig. 6, the camera heater 240 is attached to the interior surface of the glass plate 212. In this case, the harness 220 and the noise suppression sheet 230 are attached to the interior surface of the glass plate 212. In the configuration examples shown in Figs. 5 and 6, noise is suppressed by attaching the noise suppression sheet 230 to the harness 220, as in the configuration examples described with reference to Figs. 1 to 4. Furthermore, the frequency band of noise to be suppressed can be adjusted by adjusting the manner in which the noise suppression sheet 230 is attached. Note that, although the configuration examples shown in Figs. 5 and 6 describe a case in which the glass plate 210 is a laminated glass including two glass plates 211 and 212, the glass plate 210 may also be a single-layer glass.

[0040] 7 and 8, a case where a glass according to the present disclosure is applied to a glass having an antenna attached thereto will be described. Fig. 7 is a schematic front view showing a configuration example of a glass 300 according to embodiment 3. Fig. 8 is a schematic front view of a harness 320.

[0041] The glass 300 differs from the glass 100 in that it includes an antenna 340 instead of the light control film 140. Other configurations of the glass 300 are similar to those of the glass 100, and therefore, description thereof will be omitted where appropriate. The antenna 340 is an example of a device that operates using an electrical signal, and has a communication function for transmitting and / or receiving signals. For example, a DAB (Digital Audio Broadcasting) antenna or the like can be used as the antenna 340. The harness 320 is connected to, for example, a receiver (not shown), and transmits a signal received by the antenna 340 to the receiver. Such a glass 300 is suitable for use as a rear window for a vehicle.

[0042] Another antenna, such as a shark antenna, may be placed near the antenna 340. When another antenna is placed, signals generated by the other antenna may be mixed into the signals received by the antenna 340, resulting in noise. Therefore, by attaching a noise suppression sheet 330 to the harness 320, noise is suppressed before the received signals are transmitted to the receiver. In the glass 300, instead of the harness 320, a coplanar line or the like printed on the glass surface using conductive ink may be used as a signal transmission line. In this case, the noise suppression sheet 330 is attached on top of the printed coplanar line.

[0043] <Modifications, etc.> In the above-described embodiment, a specific example of a device that uses an electric signal has been described. However, the device that uses an electric signal is not limited to this, and may be, for example, a display, a lighting device, etc. Furthermore, in the above-described embodiment, a case has been described in which the glass according to the present disclosure is applied to vehicle glass. However, the glass according to the present disclosure may be applied to other uses, such as residential glass, aircraft glass, and train glass.

[0044] Next, examples of the present invention will be described. Glass samples according to the examples were prepared by the following method. Fig. 9 is a schematic diagram of glass 100 prepared as a sample. As shown in Fig. 9, glass 100 includes laminated glass 110, a harness 120, and a noise suppression sheet 130.

[0045] <Laminated Glass Configuration> The laminated glass 110 was composed of two glass sheets sandwiched between one interlayer film. The glass sheets had a thickness of 2.0 mm. The interlayer film was made of PVB. The interlayer film had a thickness of 0.8 mm.

[0046] <Harness Structure> The harness 120 was a coplanar structure harness. The base film and the cover film were made of polyimide. The thickness of the base film and the cover film was 25 μm. The conductor was copper foil. The thickness of the conductor was 18 μm.

[0047] <Configuration of Noise Suppression Sheet> The noise suppression sheet 130 used was one of the following, all manufactured by Riken Corporation: HF1, thickness 0.05 mm; HF1, thickness 0.2 mm; MF, thickness 0.05 mm; and MF, thickness 0.2 mm.

[0048] Example 1 A glass sample according to Example 1 was obtained by stacking a glass sheet, a harness, an interlayer film, and another glass sheet in this order.

[0049] Example 2 A glass sample according to Example 2 was obtained by stacking a glass sheet, a harness, a noise suppression sheet (HF1, thickness 0.05 mm), an interlayer film, and a glass sheet in this order.

[0050] Example 3 A glass sample according to Example 3 was obtained by stacking a glass sheet, a harness, a noise suppression sheet (HF1, thickness 0.2 mm), an interlayer film, and a glass sheet in this order.

[0051] Example 4 A glass sample according to Example 4 was obtained by stacking, in this order, a plate glass, a noise suppression sheet (HF1, thickness 0.05 mm), a harness, a noise suppression sheet (HF1, thickness 0.05 mm), an interlayer film, and a plate glass.

[0052] Example 5 A glass sample according to Example 5 was obtained by stacking a glass sheet, a harness, a noise suppression sheet (MF, thickness 0.05 mm), an interlayer film, and a glass sheet in this order.

[0053] Example 6 A glass sample according to Example 6 was obtained by stacking a glass sheet, a harness, a noise suppression sheet (MF, thickness 0.2 mm), an interlayer film, and a glass sheet in this order.

[0054] Example 7 A glass sample according to Example 7 was obtained by stacking a glass sheet, a noise suppression sheet (MF, thickness 0.05 mm), a harness, a noise suppression sheet (MF, thickness 0.05 mm), an interlayer film, and a glass sheet in this order.

[0055] <Measurement> To evaluate the samples prepared in this manner, S21 at both ends of the harness was measured, i.e., the signal output from one end when a signal was input to the other end. The measurement results are shown in Figure 10. Example 1 is a comparative example, and Examples 2 to 7 are working examples. As shown in Figure 10, Examples 2 to 7 suppressed noise more than Example 1, confirming the effect of the noise suppression sheet in blocking wide-band transmission. This confirmed that a high-cut transmission line can be constructed by using a noise suppression sheet.

[0056] Figure 11 is an enlarged graph of Examples 2 to 7, with Example 1 used as a reference. As shown in Figure 11, when the noise suppression sheet was attached to only one side of the harness, differences in the characteristics of the noise suppression sheet were observed, but little difference was observed due to the thickness of the noise suppression sheet. Furthermore, when the noise suppression sheet was attached to both sides of the harness, the frequency at which S21 was -3 dB, i.e., the cutoff frequency, shifted to a lower frequency range of about 100 MHz. This confirmed that the frequency band to be restricted can be changed by selectively attaching the noise suppression sheet to both two sides and one side.

[0057] <Study on Noise Suppression Sheet Length> Next, glass samples were prepared with varying lengths of noise suppression sheets. Example 11 was a sample with no noise suppression sheet attached. Examples 12 to 16 were samples with noise suppression sheets (MF, thickness 0.05 mm) attached to both sides. The lengths of the noise suppression sheets in Examples 12 to 16 were 50 mm, 100 mm, 150 mm, 200 mm, and 250 mm. The measurement results of S21 for the samples in Examples 11 to 16 are shown in FIG. 12.

[0058] Figure 13 is an enlarged graph of Examples 12 to 16, with Example 11 used as a reference. As shown in Figure 13, it was confirmed that increasing the length of the noise suppression sheet shifts the cutoff frequency to a lower range. This confirms that the frequency band to be restricted can be changed by adjusting the length of the noise suppression sheet.

[0059] Next, samples were prepared using HF1 as the noise suppression sheet. Example 21 was a sample without a noise suppression sheet attached. Examples 22 to 26 were samples with noise suppression sheets (HF1, thickness 0.05 mm) attached to both sides. The lengths of the noise suppression sheets in Examples 22 to 26 were 50 mm, 100 mm, 150 mm, 200 mm, and 250 mm. Figure 14 is a graph showing the cutoff frequencies measured in Examples 12 to 16 and Examples 22 to 26. As shown in Figure 14, it was confirmed that the cutoff frequency shifted to a lower range when the sheet length was increased in all noise suppression sheets.

[0060] The present invention has been described above in accordance with the above-mentioned embodiment, but the present invention is not limited to the configuration of the above-mentioned embodiment, and naturally includes various modifications, alterations, and combinations that a person skilled in the art can make within the scope of the invention as defined in the claims of this application.
