Publication number: 20100107561Abstract: A controller that controls a registered mark sensor stores, in a storing unit, a registered mark setting (239) which indicates a setting of the detecting sensitivity of the registered mark sensor in association with a bar code number (231). Upon reception of the bar code number (231) from a bar code reader, the controller reads out the registered mark setting (239) associated with the bar code number (231). Then the controller sets the registered mark sensor to the detecting sensitivity associated with the registered mark setting (239) thus read out.Type: ApplicationFiled: June 6, 2008Publication date: May 6, 2010Applicant: SEIKO PRECISION INC.Inventors: Yuji Nakagaki, Kazue Shirota, Masao Miura

Patent number: 4849726Abstract: A circuit breaker of a current-limiting type, which is able to open quickly by using a magnetic repulsive force generated when currents of opposite direction flow through a fixed contactor and a movable contactor which are arranged in parallel to each other. The movable contactor opens or rotates around a supporting shaft. Then, a guide pin, secured at the base portion of the movable contactor, slides into a guiding longish opening and passes over a turning point formed in the longish opening. As a result, the line of action of a compressed spring force changes its direction in order to push up the movable contactor to the full open position.Type: GrantFiled: June 13, 1988Date of Patent: July 18, 1989Assignee: Fuji Electric Co., Ltd.Inventors: Masao Miura, Isamu Osima
