Publication number: 20240061461Abstract: A pedal device to be pedaled by a user includes: a pedal supported to be swingable about an axis and to swing toward one side in a circumferential direction about the axis when being pedaled by the user; a housing; a reaction force generation portion disposed in the housing and to apply a force to the pedal toward another side in the circumferential direction; and a stopper. The stopper is arranged outside the housing, to swing about the axis together with the pedal while being supported by the pedal, and to stop the pedal by coming into contact with the housing in a non-pedaled state in which the pedal is not pedaled by the user.Type: ApplicationFiled: November 2, 2023Publication date: February 22, 2024Inventors: Atsushi NISHIMURA, Etsugo YANAGIDA, Yuki MATSUNAGA, Daisuke HOKUTO

Patent number: 11674416Abstract: A friction shim is configured to generate a frictional force between a first shim contact surface of the friction shim and a shaft end surface of a driven shaft and a frictional force between a second shim contact surface of the friction shim and an opposing surface of a second rotatable body after installation of a valve timing regulator to the driven shaft. A contact member has a first member contact surface configured to contact the shaft end surface. The contact member is installed to the second rotatable body such that the first member contact surface contacts the shaft end surface before occurrence of contact of the first shim contact surface to the shaft end surface at a time of installing the valve timing regulator to the driven shaft.Type: GrantFiled: February 24, 2021Date of Patent: June 13, 2023Assignee: DENSO CORPORATIONInventor: Yuki Matsunaga

Patent number: 11669217Abstract: An information processing apparatus (10) includes a receiver (111) configured to receive operation information corresponding to details of a cursor operation of allowing a user (U) to move the cursor (CUR); a controller (112) configured to cause a display (20) to display the cursor (CUR), based on the operation information, and a calculator (114) configured to, when the operation information includes an instruction to move the cursor positioned in one item image out of the item images (GI-1 to GI-9) toward another item image adjacent to the one item image, calculate an arrangement density of item images arranged in a direction of movement of the cursor from the one item image. The controller (112) reduces an amount of the cursor operation required for the user to move the cursor (CUR) from the one item image to the other item image to be within a range not below a predetermined lower limit value as the arrangement density calculated by the calculator (114) increases.Type: GrantFiled: March 4, 2020Date of Patent: June 6, 2023Assignee: NTT DOCOMO, INC.Inventors: Yuki Matsunaga, Aya Murakami
