Publication number: 20230384816Abstract: An input device includes an operation shaft extending in a first direction, linearly movable in the first direction, and having a tip portion; a force sensation generator configured to apply a force to the operation shaft; a sensor configured to detect an amount of movement of the operation shaft; a range-of-motion adjuster configured to change a maximum push-in position of the operation shaft; and a range-of-motion adjustment motor configured to operate the range-of-motion adjuster. The range-of-motion adjuster has a contact portion with which the tip portion of the operation shaft comes into contact. The range-of-motion adjuster changes the maximum push-in position of the operation shaft by being operated to change a contact position of the tip portion with respect to the contact portion in the first direction.Type: ApplicationFiled: August 8, 2023Publication date: November 30, 2023Inventors: Takashi NAKAI, Kazunari TAKAHASHI, Tatsuhiro TOMIYAMA

Patent number: 11536332Abstract: A torque generation apparatus includes a magnetic disc rotatable about a rotation axis, a first yoke, a second yoke, a magnetic viscous fluid placed between the magnetic disc and the first yoke and the second yoke, a coil, and a third yoke. The coil overlaps with the magnetic disc as viewed along the rotation axis. The third yoke constitutes a magnetic path of a magnetic field generated by the coil together with the first yoke and the second yoke. The magnetic disc includes a torque increasing portion at at least one of a surface facing the first yoke and a surface facing the second yoke. The torque increasing portion is provided in an outer circumferential area of the magnetic disc in a radial direction and causes a shearing force to a cluster of the magnetic viscous fluid to become larger than that in the inner circumferential area.Type: GrantFiled: November 2, 2020Date of Patent: December 27, 2022Inventors: Asuka Koike, Misuzu Takahashi, Kazunari Takahashi, Tatsuhiro Tomiyama

Patent number: 9799850Abstract: An organic electroluminescence (EL) device whose organic EL layer is less likely exposed to moisture. The organic EL device includes an organic EL layer; and a hygroscopic layer disposed with respect to at least one main surface of the organic EL layer. The hygroscopic layer includes: a hygroscopic film containing a base material and a hygroscopic agent mixed in the base material; and a pair of covering films each covering a different one of surfaces of the hygroscopic film in a thickness direction of the hygroscopic film. A region of the hygroscopic film that is in contact with one covering film whose distance from the organic EL layer is smaller than a distance of the other covering film from the organic EL layer contains the hygroscopic agent at a content rate lower than an average content rate of the hygroscopic agent in the hygroscopic film.Type: GrantFiled: July 10, 2014Date of Patent: October 24, 2017Assignee: PANASONIC CORPORATIONInventors: Yoichi Shintani, Tatsuhiro Tomiyama, Yasutaka Tsutsui
