Patent number: 7460749Abstract: The first and second light-emitting regions are provided on the light source. When the first optical fiber having the first core diameter is connected, the light emitted from the first light-emitting region enters the first core. When the second optical fiber having a greater core diameter than the first core diameter is connected, the lights emitted from the first and second light-emitting regions enter the second core. It is thus possible to connect the optical transmission device with multiple optical fibers having different core diameters. It is thus possible to provide the optical transmission device and the communication device, which are low in cost and high in convenience.Type: GrantFiled: January 25, 2005Date of Patent: December 2, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Osamu Ueno, Masao Funada, Masaaki Miura, Tsutomu Hamada, Shinya Kyozuka, Osamu Takanashi, Hideo Nakayama, Jun Sakurai, Akira Sakamoto

Patent number: 7324225Abstract: A multifunction system has advanced functions and high speed capability and is excellent in expandability. The multifunction system includes a controller, an IIT, an IOT, and a light distributing device. For a print job, print data outputted from the controller is converted into optical signals, which enter a light distributing device and are transmitted to the IOT of the emission side. The IOT prints the received data onto a printer. For a copy job, copy data outputted from IIT is converted into optical signals, which enter the light distributing device, and are transmitted to the IOT of the emission side. For a scan job, scan data outputted from the scanner is converted into optical signals, which enter the light distributing device, and are transmitted to the controller of the emission side. The controller processes the received data.Type: GrantFiled: May 29, 2001Date of Patent: January 29, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Shinobu Ozeki, Tsutomu Hamada, Junji Okada, Masao Funada, Takeshi Kamimura, Hidenori Yamada, Kazuhiro Sakai, Shinya Kyozuka, Hiroki Ishida, Osamu Takanashi, Masaaki Miura, Kenichi Kobayashi, Tsuyoshi Yaguchi, Kazuhiro Hama, Toshiki Matsui, Yasuhiro Arai, Hirotaka Mori

Patent number: 7308205Abstract: In an optical transmission apparatus in which a plurality of nodes are optically connected to one another via an optical transmission path, a light signal which is coded so that a mixture ratio of 1 and 0 constituting data is made close to 50% is transmitted through the optical transmission path. When a light signal is not emitted from all of the nodes, a dummy signal which is an AC-like signal is emitted to the optical transmission path. Therefore, an optoelectric conversion section can be always set to an active state, and the signal recognizability can be prevented from being lowered.Type: GrantFiled: March 27, 2003Date of Patent: December 11, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Shinobu Ozeki, Akira Toshima, Masao Funada, Kenichi Kobayashi, Hidenori Yamada, Takeshi Kamimura, Yoshihide Sato, Junji Okada, Takehiro Niitsu, Shinya Kyozuka, Kazuhiro Sakai, Kazuhiro Suzuki, Tomo Baba, Tsutomu Hamada, Masaru Kijima, Osamu Takanashi, Masaaki Miura, Osamu Ueno

Patent number: 7039274Abstract: In a device of the present invention for allowing signal light to enter a light guide body using an optical fiber, a light guide body, which is constituted by dispersing particles for scattering the signal light in an optical medium, is selected as a light guide path which requires an area where a light diffusing function is performed just after incidence of the signal light. An optical connecting material intervenes between one end of the optical fiber from which the signal light is output and opposed one end surface of a particle dispersing light guide body and a desired diffusing function is obtained.Type: GrantFiled: October 30, 2003Date of Patent: May 2, 2006Assignees: Fuji Xerox Co., Ltd., Fuji Photo Film Co., Ltd.Inventors: Junji Okada, Takehiro Niitsu, Tsutomu Hamada, Masao Funada, Hidenori Yamada, Shinya Kyozuka, Tomo Baba, Shinobu Ozeki, Osamu Takanashi, Masaaki Miura
