Patent number: 9966212Abstract: The blinking device includes multiple power terminals, multiple load terminals, multiple contact switches, a control circuit, and multiple mounting substrates, and a case in a box shape for accommodating these therein. The multiple contact switches are individually associated with multiple power supply paths individually connected to multiple pairs each defined as a pair of one power terminal of the multiple power terminals and one load terminal of the multiple load terminals. At least one power supply path of the multiple power supply paths is formed on at least one of a front face, where at least one contact switch is mounted, and a rear face, where no contact switch is mounted, of each of the multiple mounting substrates. The case is configured to accommodate the multiple mounting substrates so that the multiple mounting substrates are stacked in a thickness direction.Type: GrantFiled: December 6, 2013Date of Patent: May 8, 2018Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Yasuhiro Sumino, Kiwamu Shibata

Patent number: 9812803Abstract: A socket includes power-supply blade receivers and a grounding blade receiver for retaining power-supply plug blades and a grounding plug blade of a plug, respectively. Each of the power-supply blade receivers includes a power-supply retaining portion and a power-supply contact portion. The grounding blade receiver includes a grounding retaining portion and a grounding contact portion which is installed further on the upstream side in the insertion direction of the plug than a position which is spaced away from the power-supply contact portion to the downstream side in the insertion direction by less than the certain distance. The grounding retaining portion is spaced away by the certain distance or more from the power-supply retaining portion to the downstream side in the insertion direction.Type: GrantFiled: January 15, 2016Date of Patent: November 7, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hiroyuki Toyoda, Satoru Tanaka, Kiwamu Shibata, Noboru Hashimoto, Kazuya Baba

Patent number: 6252185Abstract: In the setting operation conducted by the handle 90 which is an operating section, an upper portion of the portion 26a′ of the slidable T-post 26 is pushed by the end portion of the cam 90b, and the slidable T-post 26 is moved. In accordance with the movement of the card 26, the suction cup block 23 is elastically deformed, and the suction cup 23b is held by the body 24 by a holding force of the suction cup 23b. The body 24 is composed of a porous body, and air flows from the ventilation hole 29 into a space formed between the suction cup 23b and the body 24, via the body 24. The slidable T-post 26 is biased ahead by the return spring 27. When the releasing operation is conducted by the handle 90, the cam 90b is rotated, and the end portion of the cam 90b is separated from the end of the portion 26a′ to be pushed.Type: GrantFiled: May 31, 2000Date of Patent: June 26, 2001Assignee: Matsushita Electric Works, Ltd.Inventors: Kiwamu Shibata, Hideya Kondo, Takaaki Chuzawa, Jun Saito, Nobuhiro Kitamura, Tetsuyasu Kawamoto, Satoshi Kajiyama, Takeshi Ono

Patent number: 5389905Abstract: A damper is provided by a plurality of chambers defined between stacked thin sheet members and containing a fluid for flowing therein through a communicating section, the chambers being made to be of a small height in the direction perpendicular to the plane of the sheet members and to form a buffer section with at least one of the chambers. With such damper employed in electromagnet assemblies and eventually relays including the assemblies, they can be sufficiently minimized in size, and their manufacture can be also made extremely easier.Type: GrantFiled: April 15, 1993Date of Patent: February 14, 1995Assignee: Matsushita Electric Works, Ltd.Inventors: Kiwamu Shibata, Yoichi Yokoyama, Manabu Yano, Nobuhiro Kitamura, Naoki Kanemoto, Tetsuyasu Kawamoto
