Patent number: 9698662Abstract: A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.Type: GrantFiled: March 15, 2012Date of Patent: July 4, 2017Assignee: OMRON CorporationInventors: Masaki Sugihara, Kazuyuki Tsukimori, Makoto Wada, Kenshi Nagata

Patent number: 9419496Abstract: A return mechanism is achieved which requires only a small force for operation. In one aspect of the present invention, a return mechanism (10) includes: a first spring (1) that acts between an operating section (11) and a working section (12); and a second spring (2) that acts between the operating section (11) and a base (13). A direction in which the second spring acts when the operating section (11) is in a first position is not parallel to a direction in which the second spring (2) acts when the operating section (11) is in a second position. A component which, of a force of the second spring, acts in a direction of motion of the operating section (11) is smaller when the operating section (11) is in the second position than in the first position.Type: GrantFiled: May 30, 2014Date of Patent: August 16, 2016Assignee: OMRON CorporationInventors: Yohei Tsukanaka, Satoru Nishimaki, Makoto Wada, Kazuyuki Tsukimori

Publication number: 20160189894Abstract: One aspect of the present invention provides a limit switch that is returned to an original position even if a turning angle of a turning lever becomes 90 degrees. In a section perpendicular to a turning shaft, a cam is formed such that a whole contact surface of the cam with a cam receiver is located on a side of the cam receiver with respect to a shaft center of the turning shaft when the external force does not act on the turning lever.Type: ApplicationFiled: November 23, 2015Publication date: June 30, 2016Inventors: Kazuyuki TSUKIMORI, Manabu TAKAHASHI, Yuki YAMAMOTO

Publication number: 20160141118Abstract: A limit switch includes fixed contacts and a movable contact, the fixed contacts and the movable contact formed from an Au—Ni metal alloy of no less than 97% Au by weight. The limit switch detects position, change, movement, number of passes, or the like and outputs an “on” signal or an “off” signal depending on whether a detection occurred.Type: ApplicationFiled: November 17, 2015Publication date: May 19, 2016Inventor: Kazuyuki TSUKIMORI

Publication number: 20150213977Abstract: It is an object of the present invention to provide a switch with which heat resistance and cold resistance can both be increased inexpensively. This switch comprises a bearing member, a shaft, a manipulation member, and a switch main body. The shaft is slidably supported by the bearing member. The manipulation member is linked to the shaft. The switch main body switches a contact according to displacement of the shaft. The shaft or the bearing member includes a sliding face having a groove.Type: ApplicationFiled: January 9, 2015Publication date: July 30, 2015Inventors: Yuki YAMAMOTO, Makito MORII, Kazuyuki TSUKIMORI, Manabu TAKAHASHI

Publication number: 20150114806Abstract: A switch has a switching mechanism, a housing in which the switching mechanism is disposed, and a slidable actuator that causes the switching mechanism to operate. At least one connection which can be in direct contact with outside air, out of connections between members of the switch, is provided with a sealing member. Rubber contained in the sealing member includes fluorocarbon rubber and does not include silicone rubber.Type: ApplicationFiled: September 29, 2014Publication date: April 30, 2015Inventors: Kazuyuki Tsukimori, Manabu Takahashi, Yuki Yamamoto, Hidenori Yamamoto

Publication number: 20150114805Abstract: A switch has a rotary shaft that rotates in response to an external force, a cam provided on the rotary shaft and including a cam action section, wherein the cam rotates in response to the rotation of the rotary shaft, a displacement member including a cam support section that contacts the cam action section, wherein the displacement member is displaced in response to the cam support section being pressed by the cam action section rotating, and a switch module that performs an on-off action in response to the displacement of the displacement member. The cam action section is made of a metal. The cam support section is made of a resin softer than the cam action section.Type: ApplicationFiled: September 25, 2014Publication date: April 30, 2015Inventors: Kazuyuki Tsukimori, Manabu Takahashi, Hiroyuki Moriyama, Shinya Katsube, Yuki Yamamoto
