Patent number: 7375429Abstract: Disclosed are an integrated circuit component capable of simply mounting at low cost a chip part which adjusts impedance of wiring patterns as well as capable of effectively reducing switching noise from an integrated circuit, and a method for mounting the chip part. The integrated circuit component of the present invention has a constitution that a bypass capacitor is mounted on a wiring board side of a gap between the wiring board and an LSI chip. Therefore, as compared with a case where the capacitor is mounted on the LSI chip side, a transmission path through the capacitor can be extremely shortened. As a result, inductance components of the feeder line can be reduced, so that a response delay of power transmitted through the feeder line can be sufficiently suppressed.Type: GrantFiled: December 29, 2005Date of Patent: May 20, 2008Assignee: Fujitsu LimitedInventors: Yasuhiro Teshima, Noboru Nakama

Publication number: 20040235319Abstract: A shelf-type telecommunications device has a back wired board assembly mounted on a back of a shelf unit into which a plurality of plug-in units are inserted side by side. The back wired board assembly has a main back wired board to which at least one plug-in unit is connected and a sub back wired board to which at least one external cable is connected, the outer surface of the main back wired board and the inner surface of the sub back wired board opposing each other. The main back wired board and the sub back wired board are fitted together by using a plurality of relay connectors or pin terminals so as to electrically connect the main back wired board and the sub back wired board to each other without the need for coaxial cables, thus reducing the size of the device.Type: ApplicationFiled: March 11, 2002Publication date: November 25, 2004Inventors: Shozo Shimada, Hirofumi Imabayashi, Mitsuo Kaetsu, Noboru Nakama, Takashi Sekiguchi

Publication number: 20030089514Abstract: A power supply terminal that prevents damage to capacitors included in a noise filter circuit therein which may occur due to a BWB's warp or thermal stresses at soldering time. The noise filter circuit is formed on a noise filter circuit substrate, being a substrate separate from the BWB. The noise filter circuit substrate is connected conductively to part of each of press fit terminals.Type: ApplicationFiled: December 12, 2002Publication date: May 15, 2003Inventors: Junichi Hayama, Noboru Nakama, Tetsuya Murayama, Kenji Tsutsumi, Satoshi Tojo, Hiroshi Kadoya, Kiyonori Kusuda, Kenji Toshimitsu

Patent number: 5513995Abstract: An electrical connecting arrangement is provided for establishing electrical connections of electronic printed-circuit boards detachably mounted in a cabinet of an electronic installation at a front side thereof. For the establishment of electrical connections, at least one connector is used, and a connector support member is attached to a rear side of the cabinet. The connector includes two connector halves to be coupled to each other. One of the connector halves is detachably attached to and supported by the support member, and is joined to an end of an electrical cable. The other connector half is securely attached to and by a rear side of the printed-circuit board. The connector halves are aligned with each other upon mounting the printed-circuit board in the cabinet, to thereby ensure coupling of the connector halves.Type: GrantFiled: April 22, 1994Date of Patent: May 7, 1996Assignee: Fujitsu Ltd.Inventors: Fumio Kurotori, Norihiro Takahashi, Hideo Miyazawa, Noboru Nakama, Shozo Shimada, Norio Suzuki, Kazuya Oorui

Patent number: 5412497Abstract: An optical communication device comprising a horizontally rectangular main shelf, and a horizontally rectangular sub-shelf arranged in a vertically overlapping relationship with the first shelf. The main shelf and the sub-shelf have parallel guide rails in register with each other. Unit plates comprising optical modules for optical-electrical signal conversion are inserted in the main shelf in upright positions for engagement with the respective guide rails. Optical fiber supporting plates having means for supporting the optical fiber having a surplus length portion coiled in a freely extendable manner are inserted in the sub-shelf in upright positions for engagement with the respective guide rails. Accordingly, the surplus length portions of the optical fibers are orderly arranged in correspondence with the optical modules so as to prevent an incorrect connection between the optical fibers and the optical modules.Type: GrantFiled: February 22, 1993Date of Patent: May 2, 1995Assignee: Fujitsu LimitedInventors: Mitsuo Kaetsu, Noboru Nakama, Kazuaki Kashiwada

Patent number: 4896317Abstract: A supervisory system for a primary group digital transmission line wherein a terminal repeater transmits, over a supervisory line, address information designating an intermediate repeater and line within the intermediate repeater to be monitored while the line is in a normal, in-service condition. The terminal repeater and intermediate repeaters are cascade connected by way of the supervisory line. The terminal repeater and each of the intermediate repeaters include amplifiers that receive and send information along the transmission line, and have a monitor output. The monitor output is processed by an error monitor within the terminal repeater and in each of the intermediate repeaters and the results of the error monitoring provided to the supervisory line in response to polling by the terminal repeater.Type: GrantFiled: February 11, 1988Date of Patent: January 23, 1990Assignee: Fujitsu LimitedInventors: Noboru Nakama, Hideyuki Motoori, Atsushi Suzuki, Eiji Sugawara, Naoyuki Kato
