Patent number: 10657778Abstract: The disclosure provides a door switch that improves visibility. The door switch includes an actuator and a sensor. In addition, the door switch is installed so that when a door is closed, a surface of the sensor and an opposite surface of the actuator are in contact with or close to each other, and when the door is open, the surface of the sensor and the opposite surface of the actuator are separated from each other. The actuator outputs a detection signal. A display part for indicating a reception state of the detection signal is formed on the surface of the sensor. The surface of the sensor has a non-opposite region, wherein the non-opposite region is at least a part of the display part not opposite to the opposite surface of the actuator in the reception state.Type: GrantFiled: November 14, 2018Date of Patent: May 19, 2020Assignee: OMRON CorporationInventors: Rina Su, Keishi Yayama, Kazuhiro Kudo, Kenji Shimazu

Patent number: 8993189Abstract: A heat-resistant alloy capable of effectively suppressing diffusion of Cr, as well as an alloy member for a fuel cell, a fuel cell stack device, a fuel cell module and a fuel cell device are provided. A heat-resistant alloy includes a Cr-containing alloy, and a Cr-diffusion suppression layer located on at least a part of a surface of the Cr-containing alloy, the Cr-diffusion suppression layer being made by laminating a first layer that contains a Zn-containing oxide and a second layer that does not contain ZnO but contains an (La, Sr)MnO3-based perovskite oxide in that order, so that it is possible to effectively suppress diffusion of Cr. By using the heat-resistant alloy for an alloy member for a fuel cell, a fuel cell stack device, a fuel cell module and a fuel cell device each having improved reliability can be obtained.Type: GrantFiled: January 25, 2010Date of Patent: March 31, 2015Assignee: Kyocera CorporationInventors: Masahiko Higashi, Tetsurou Fujimoto, Norimitsu Fukami, Kenji Shimazu

Patent number: 7585183Abstract: Switches for a variety of circuits for different purposes are formed by using a plurality of similarly designed contact modules each having a module case incorporating a normally closed or normally open contact mechanism and a plunger for operating this contact mechanism, a single actuator having two end parts and being biased so as to rotate around a supporting axis between these contact modules, this actuator undergoing a rotary motion if a force is applied to one of its end parts so as to operate the plunger of an associated one of the contact modules with at least one of the end parts, a switch case that contains the contact modules and the actuator, and a push button for applying a force on one of the end parts of the actuator from outside the switch case.Type: GrantFiled: August 10, 2007Date of Patent: September 8, 2009Assignee: OMRON CorporationInventors: Kenji Shimazu, Shunkichi Sasaki, Hidemitsu Takenaka, Tetsuya Fukumoto

Patent number: 7504597Abstract: A key switch has a switch part and an operating part. The switch part is activated to switch contact points as an operating key is inserted. The operating part includes a driver cam that rotates as it is pushed by the operating key and to activate the switch part and a plurality of lock cams configured to directly lock the driver cam in a normal condition when the operating key is pulled out of the operating part and to rotate as it is pushed by the operating key so as to release the driver cam from its locked condition. The key switch may further include lock cam holder for holding the lock cams in the normal condition when the operating key is pulled out.Type: GrantFiled: February 20, 2007Date of Patent: March 17, 2009Assignee: OMRON CorporationInventors: Kenji Shimazu, Shunkichi Sasaki, Hidemitsu Takenaka, Tetsuya Fukumoto, Shinya Yamamoto, Shinya Watanabe

Patent number: 7456368Abstract: In order to perform maintenance of a working robot, a worker pulls a handle of a slider and moves the slider backward to thereby withdraw a slider fitting portion from a fitting hole portion and withdraw an actuator from an operating portion of a door switch. In this case, a key inserted into a key hole of a lock is rotated through 90° to vertically orient an interference protruding portion to thereby prevent fitting of the slider fitting portion into the fitting hole portion. Only in this state, the key can be withdrawn from the key hole of the lock.Type: GrantFiled: February 21, 2007Date of Patent: November 25, 2008Assignee: Omron CorporationInventors: Tetsuya Fukumoto, Yoichi Shude, Shigeki Nakanishi, Shunkichi Sasaki, Hidemitsu Takenaka, Kenji Shimazu
