Patent number: 7415111Abstract: An optical network unit and an optical line terminal which efficiently control the data receiving and dechurning processes in a passive optical network. In a churning parameter memory subsystem, a first memory bank stores churning parameters that are currently used, while a second memory bank stores updates made to the churning parameters. Under the control of the churning parameter memory subsystem, those first and second memory banks change their roles with each other at a churning key updating time point. A data dechurning unit receives a data stream consisting of a plurality of frames and dechurns the information contained in the data stream, according to the stored churning parameters. When an update is done to the parameters in a certain frame, the data dechurning unit makes the update effective at the next frame, thus starting data dechurning operations from the next frame.Type: GrantFiled: October 7, 2004Date of Patent: August 19, 2008Assignee: Fujitsu LimitedInventors: Takashi Monzawa, Kenji Miura, Tamotsu Matsuo, Hideki Shiono, Yoshimi Toyoda, Toshinori Koyanagi, Setsuo Abiru, Jun Asato, Shinichi Fujiyoshi, Kazuhiro Uchida, Kazuya Ryu, Katsuhiko Hirashima, Tateo Shimaru, Mitsuharu Wakayoshi, Toshiyuki Sakai

Patent number: 7006409Abstract: It is an object of the present invention to provide an improved disc changer adapted to exactly detect whether a magazine storing a plurality of discs has been attached in the disc changer. When a magazine storing a plurality of discs is inserted into the disc changer, a detection arm and a lock arm both serving as moving members are moved by such an insertion. The lock arm, by virtue of the movement of itself, engages into an insertion groove provided on the backside of the inserted magazine and locks the magazine on the disc changer. The detection arm, by virtue of the movement of itself, actuates a lock detection switch. Here, since the detection arm and the lock arm are both urged by an urging spring, it becomes possible to exactly detect the attachment of the magazine by allowing the moving members locking the magazine on the disc changer to actuate the lock detection switch.Type: GrantFiled: August 6, 2003Date of Patent: February 28, 2006Assignee: Pioneer CorporationInventors: Jun Togashi, Hideki Kinoshita, Satoru Anada, Takashi Ota, Kiyoshi Morikawa, Toshiyuki Sakai, Shoichi Naruse

Patent number: 6901670Abstract: A scribing head 1 of this invention raises and lowers a scribing cutter by rotation of a servomotor 3. As a scribe pressure, a rotational torque of the servomotor 3 is transmitted to the scribing cutter. To form a scribe line across another scribe line which is formed earlier, the scribe pressure is raised temporarily when the scribing head passes the scribe line which is formed earlier. The rotational torque of the servomotor 3 is controlled at any of preset limits while the position of a cutter 6 of the scribing head shifts on the brittle substrate. The servomotor 3 is driven under position-control mode.Type: GrantFiled: July 18, 2002Date of Patent: June 7, 2005Assignee: Mitsuboshi Diamond Industrial Co., Ltd.Inventors: Haruo Wakayama, Toshiyuki Sakai, Keiko Hayashi, Yoshitaka Nishio, Junichi Matsumoto
