  • Publication number: 20250052627
    Abstract: [Object] To provide a pressure detection panel that allows suppressing the cost required for an FPC and obtaining in-plane uniformity of a detection signal of a pressing force even when a panel size is large. [Solution] A pressure detection panel 1 of the present invention includes a surface panel 2 and one strain sensor 3 arranged on a back surface of the surface panel 2 in a strip shape along one side of the surface panel 2. The strain sensor 3 includes sensitive units R1, R2, and R3 at an intermediate portion and both end portions in a longitudinal direction. The adjacent sensitive units, that is, the sensitive units R1 and R2 and the sensitive units R2 and R3, are mutually connected in series by a wiring line 31.

  • Publication number: 20250033085
    Abstract: An ultrasonic wave converging part (12) and a waveguide (13) have a through-hole (20) penetrating the converging part and the waveguide in a front-rear direction. An inner circumferential surface (20A) forming the through-hole has inner circumferential surface (21) and deformed portion (23) located on a front-end side relative to the inner circumferential surface. The inner circumferential surface has, as a cross-sectional shape in the front-rear direction, a shape linearly extending in the front-rear direction. The deformed portion is, in a cross section in the front-rear direction, at least one of a portion located inward of the inner circumferential surface and a portion located outward of the inner circumferential surface (FIG. 1 showing the portion located inward of the first inner circumferential surface), and is formed in a part of or over an entire circumference (FIG. 1 showing the entire circumference) of the inner circumferential surface in a circumferential direction.

  • Publication number: 20240359608
    Abstract: A plurality of pressing portions 38 protrude inward in a radial direction from an inner peripheral surface of a tubular main body portion 35 (part of a tube body) and are each fixed at both ends thereof in an up-down direction to the main body portion 35. Since the plurality of pressing portions 38 are aligned in the up-down direction, a stay 22 or 23 can be inhibited from oscillating with a contact portion between one pressing portion 38 and the stay 22 or 23 as a fulcrum. As a result, rattling of the stay 22 or 23 relative to a headrest holder 30 or 31 can be suppressed.

  • Patent number: 11932152
    Abstract: An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.

  • Patent number: 11868157
    Abstract: A conductive sheet includes a transparent substrate and a plurality of thin metal wires formed in a mesh shape on one surface of the transparent substrate. The plurality of thin metal wires includes an n-sided polygon formed in a virtual pattern and an inverted virtual pattern and six connecting lines. The virtual pattern and the inverted virtual pattern obtained by flipping the virtual pattern horizontally are densely laid such that intersection points disposed on respective sides of the virtual pattern and the inverted virtual pattern are overlapped with each other and that opening regions formed by the plurality of thin metal wires are aperiodically arranged.

  • Patent number: 11762517
    Abstract: A touch panel includes: first electrodes disposed in parallel at a position corresponding to a viewing area of a panel member and have a capacitance changing according to a proximity of an object to be detected; second electrodes that intersect with the first electrodes, are disposed in parallel, and similarly change in capacitance; third electrodes disposed in parallel between the first or second electrodes and have electrical resistances changing according to posture and temperature; and fourth electrodes extending along the respective third electrodes and similarly change in electrical resistance. A resistance change rate of the fourth electrodes due to temperature is the same as for the third electrodes. The resistance change rate of the fourth electrodes due to the posture change is 90% or less than for the third electrodes due to the posture change. This allows a pressing force to be accurately measured.
