Publication number: 20090072936Abstract: Magnetic attractive force of a magnet exerted on a movable contact in a sealing case through yokes changes as a result of movement of a magnetic shunt element induced by movement of a movable element located outside the sealing case. As a result, the movable contact can be brought into or out of contact with a stationary contact without involvement of entry of the movable element into the sealing case.Type: ApplicationFiled: April 22, 2008Publication date: March 19, 2009Applicants: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHO, NEC TOKIN CorporationInventors: Tomio Yamada, Katsuhide Kumagai, Masahiko Miyata, Yoshinori Ota, Tatsumi Ide

Publication number: 20080017588Abstract: Carbon dioxide is supplied from a carbon dioxide cylinder (15) to a pressure vessel (13) through reducing valves (18 and 19). The pressure vessel (13) is also supplied with a sodium hypochlorite water solution having a desired concentration through a material supply pipe (12). The material supply pipe (12) is connected to first and second branch pipes (100 and 101) through a distribution valve (102). The sodium hypochlorite water solution supplied through the material supply pipe (12) is partially sprinkled to a gas-phase region in the pressure vessel (13) through the first branch pipe 100, while the remainder of the sodium hypochlorite water solution is supplied to a liquid-phase region in the pressure vessel (13) through the second branch pipe (101). The pressure vessel (13) is provided with a liquid level retention mechanism (25 to 29) is provided to retain the liquid level in the pressure vessel (13) within a constant range.Type: ApplicationFiled: August 22, 2007Publication date: January 24, 2008Applicants: VEETA INC., APRO CO., LTD.Inventors: Tatsuo Okazaki, Yoshinori Ota, Hiroshi Teranishi

Patent number: 6896530Abstract: A housing body is formed with an opening, and a cavity communicated with the opening and into which a mating connector terminal inserted through the opening in a first direction is fitted. An internal terminal is provided in the cavity to be electrically connected to the mating connector terminal fitted into the cavity. A pair of shutter members are disposed outside the cavity such that a part of each of the shutter members is movable in a second direction which is perpendicular to the first direction, between a first position for concealing a part of the opening and a second position for revealing the part of the opening. An urging member urges each of the shutter members toward the first position, so that the mating connector terminal moves the shutter members toward the second position against an urging force of the urging member when the mating connector terminal is fitted into the cavity.Type: GrantFiled: June 30, 2004Date of Patent: May 24, 2005Assignee: Mitsumi Electric Co., Ltd.Inventors: Atsushi Nishio, Yoshinori Ota, Yuji Tsujii

Patent number: 6437797Abstract: The image reproducing method of the present invention includes the steps of: reading captured images and GPS information relating to each captured image, recorded by a camera connected to a GPS unit; reading desired map data from a recording medium which contains map data; displaying, on a monitor, a digital map including the capturing places of the read captured images; and displaying a thumbnail of each read captured image at an appropriate position on the digital map. Thus, it is possible to easily see the capturing place of each captured image and produce the albums in accordance with the capturing places with reference to the displayed image. Markers indicating the capturing places and lines drawn between the markers may be displayed to show the image-capturing route.Type: GrantFiled: February 18, 1998Date of Patent: August 20, 2002Assignee: Fuji Photo Film Co., Ltd.Inventor: Yoshinori Ota
