  • Patent number: 11947766
    Abstract: A touch panel device includes a first conductive film having first and second regions, at least a part of the first conductive film between the first and the second regions being removed, a second conductive film laminated on the first conductive film across a gap, first and second terminals that output signals, a first electrode electrically connected to the first terminal, a second electrode facing the first electrode across the first region, a first resistor provided on the first conductive film in the second region and having a pair of electrodes, the pair of electrodes facing each other across a first resistance region in the first conductive film, one of the electrodes being electrically connected to the second electrode, the other of the electrodes being electrically connected to the second terminal, and a first switch electrically connecting the first conductive film to the second conductive film, in the second region.

  • Patent number: 10307972
    Abstract: Provided herein is an apparatus of manufacturing a molding material that can significantly reduce the frequency of replacement of a bottom member without increasing the drainage time longer. A bottom member (39) is constituted of two layers of wire meshes including an annular dutch-woven wire mesh (39A) made of stainless steel and an annular plain-woven wire mesh made of stainless steel. The two layers of wire meshes are secured to each other by sintering. A support plate (40) made of stainless steel is disposed between the bottom member (39) and a lower hollow compression mold (2). The support plate (40) has a plurality of through holes (41) formed therein, and is configured to support the bottom member (39).

  • Patent number: 10265886
    Abstract: Provided herein is a molding material that attains little fluctuation in amount of short fibers and powdery resin among individual products and that allows continuous production without damaging a die. In the step of pouring, slurry is poured onto a slurry diffusion member 7 from above the slurry diffusion member 7. The slurry diffusion member 7 extends in an upward direction, and is shaped such that the area of a transverse section taken along a direction orthogonal to the upward direction becomes smaller as the slurry diffusion member 7 extends in the upward direction. In the step of cleaning, a dispersion medium that is the same as the dispersion medium used in the step of pouring or water is poured onto the slurry diffusion member 7 from above the slurry diffusion member 7 to cause the short fibers and the powdery resin adhering to a slurry diffusion portion 71 of the slurry diffusion member 7 to fall down.

  • Patent number: 9962887
    Abstract: There is little fluctuation in amount of short fibers among individual products of fiber substrate. No damage is caused to a mold for the fiber substrate. Continuous production of the fiber substrates is possible. A method of manufacturing a fiber substrate includes the steps of: preparing slurry by dispersing short fibers in a dispersion medium; pouring the slurry into a cylindrical mold from above the cylindrical mold, the slurry being directed to a slurry diffusion member disposed in the center of the cylindrical mold and having an upward pointing conical or pyramidal shape; pouring the dispersion medium or water onto the slurry diffusion member from above the slurry diffusion member to cause the short fibers adhering to the slurry diffusion member to fall down, after the step of pouring the slurry; and discharging the dispersion medium from the cylindrical mold to accumulate the short fibers in the cylindrical mold to obtain a fiber aggregate.

  • Patent number: 9925700
    Abstract: Provided herein is an apparatus of manufacturing a molding material for use in a method of manufacturing a molding material that can prevent a crack from occurring in the molding material. A cylindrical die (3) is slid downward along an upper hollow compression mold (4) and a lower hollow compression mold (2) with a molding material (35) held between the upper hollow compression mold (4) and the lower hollow compression mold (2). After that, the upper hollow compression mold (4) is moved upward to relatively move the upper hollow compression mold (4) and the lower hollow compression mold (2) away from each other. After a slurry diffusion member (7) is removed, the molding material (35) is taken out.
