Patent number: 10133296Abstract: A multidirectional operating device includes an operational knob including a knob body and plural ribs, and a bezel portion disposed around a rotational axis of the operational knob. The bezel portion includes plural limiting portions formed standing from a top surface side so as to limit the inclination operation of the operational knob by being opposite to a contact surface of the ribs when the operational knob is located at a neutral position, and plural permitting portions arranged between the limiting portions so as to permit the inclination operation of the operational knob while avoiding a contact with the contact surface of the ribs when the operational knob is located at an operational position that allows the inclination operation by being rotated from the neutral position to a right or left position.Type: GrantFiled: September 18, 2017Date of Patent: November 20, 2018Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Masahito Hisada, Yusuke Kumakiri

Patent number: 9959998Abstract: A switch device includes an operation part, a first push mechanism that, by a rotation operation of the operation part, selects and activates a first push switch part, a second push mechanism that, by a tilt operation of the operation part, activates a second push switch part, a circuit board including the first push switch part and the second push switch part mounted thereto, and a contact rubber interposed between the circuit board and the first and second push mechanisms. The contact rubber includes contacts corresponding to the first push switch part and the second push switch part and is configured such that the contacts contact with or separate from the corresponding switch parts by a movement of the first push mechanism and the second push mechanism. The contact rubber is formed so as to cover an entire upper surface of the circuit board.Type: GrantFiled: June 2, 2016Date of Patent: May 1, 2018Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Masahito Hisada, Makoto Kobayashi

Patent number: 9336972Abstract: A switch device includes a lever and a pusher. The pusher includes a surface that contacts the lever. When force is applied from the lever to the pusher, an inclined surface of the pusher produces a force that moves the pusher from a one-side pushing position to a two-side pushing position. This allows for a user to apply a smaller force to the lever in order to move the pusher from the one-side pushing position to the two-side pushing position and thereby push two switch units.Type: GrantFiled: August 29, 2013Date of Patent: May 10, 2016Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Masahito Hisada, Makoto Kobayashi, Nobuhiko Kitagawa

Patent number: 9129764Abstract: A switch device includes a lever. A switch body is arranged in the lever. The switch body supports the lever in a tiltable manner. At least one pusher is moved by contact with the lever when the lever is tilted. At least one switch unit is pushed when the pusher moves. A resiliently deformable sealing member is arranged between the lever and the switch body where air including dust may enter. The sealing member is separated from a location where the pusher comes into contact with the lever, and the sealing member is resiliently deformed when the lever is tilted.Type: GrantFiled: August 29, 2013Date of Patent: September 8, 2015Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Masahito Hisada, Makoto Kobayashi

Patent number: 8967021Abstract: An operating device includes a dial that has a first engagement portion, a rotational body that is formed in an annular shape, and has a second engagement portion so as to be engaged with the first engagement portion of the dial. Rotation of the dial is transmitted to the rotational body through an engagement of the first and second engagement portions. The operating device also includes gear teeth that are provided on an inner circumferential portion of the rotational body, a gear that is meshed with the gear teeth and is rotated in an inner space of the rotational body, and a rotation response member that is directly coupled to a rotation shaft of the gear and varies in accordance with a rotation angle of the dial.Type: GrantFiled: January 4, 2013Date of Patent: March 3, 2015Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Masahito Hisada, Yoshinori Takano, Yoshiyuki Aoki

Publication number: 20060145385Abstract: Production of a yarn, using a spinneret having numerous spinning holes arranged in a straight line(s), and a spinning tube installed below it, spaced from it, and having a filament passage rectangular in cross section with its long side direction agreeing with the direction in which the spinning holes are arranged side by side, wherein gas is injected from the injection holes formed on both the long sides of the filament passage for injecting gas obliquely downward to the filaments, for disposing the numerous filaments in a row and for forming a gas stream flowing downward in the filament passage, characterized in that the speed of the gas stream flowing downward in the filament passage is not less than 60% of the take-up speed of the numerous filaments, or that the gas generated from the numerous filaments is sucked and discharged outside, in the range between the spinneret and the spinning tube. Even if the yarn runs at a high speed, the obtained yarn can have a high elongation.Type: ApplicationFiled: May 28, 2003Publication date: July 6, 2006Inventors: Takashi Fujii, Takao Sano, Hiroki Furuta, Masahito Hisada
