Publication number: 20250052627Abstract: [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.Type: ApplicationFiled: March 23, 2023Publication date: February 13, 2025Applicant: NISSHA CO.,LTD.Inventor: Takashi YOKOYAMA

Publication number: 20250033085Abstract: 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.Type: ApplicationFiled: November 21, 2022Publication date: January 30, 2025Applicant: NITERRA CO., LTD.Inventors: Shinsuke ITOH, Kota YOKOYAMA, Satoshi SUZUKI, Ryo SUZUKI, Takashi KASASHIMA

Publication number: 20240359608Abstract: 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.Type: ApplicationFiled: April 25, 2024Publication date: October 31, 2024Applicant: TACHI-S CO., LTD.Inventors: Keita Myochin, Takashi Yokoyama, Atsushi Koike, Shogo Suzuki

Patent number: 11762517Abstract: 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.Type: GrantFiled: June 10, 2020Date of Patent: September 19, 2023Assignee: NISSHA CO., LTD.Inventors: Yuji Watazu, Takashi Yokoyama, Yuichiro Yonemura
