Patent number: 7641397Abstract: The head end surface of an optical fiber (2) and the head end surface of an optical fiber (12) are butted to each other in an alignment member (22) of an adapter (21). In the butting, because one of the members clasping the optical fiber (2) is a plate (4a) that is short, the optical fiber (2) is bent and buckled between the left end of the short plate and the right end of the alignment member. Members clasping the optical fiber (12) are a long plate (14b) and a V-grooved base plate (13), and the optical fiber (12) is therefore horizontally fixed between each of right ends of the long plate and of the V-grooved base plate (13) and the left end of the alignment member. This results that the head end surface of the optical fiber (2) and the head end surface of the optical fiber (12) are in tight contact with each other, achieving excellent optical transmission between both optical fibers.Type: GrantFiled: August 31, 2004Date of Patent: January 5, 2010Assignees: Japan Aviation Electronics Industry, Limited, Nippon Telegraph and Telephone Corporation, Hirose Electric Co., Ltd.Inventors: Yuichi Koreeda, Akihiro Onogawa, Yoshiteru Abe, Masaru Kobayashi, Ryou Nagase, Masahiro Tsuchida, Koichi Arishima

Patent number: 7397977Abstract: A wave transmission medium includes an input port 3-1 and an output port 3-2. A field distribution 1 and a field distribution 2 are obtained by numerical calculations. The field distribution 1 is a field distribution of the propagation light (forward propagation light) launched into the input port 3-1. The field distribution 2 is a field distribution of the phase conjugate light (reverse propagation light) resulting from reversely transmitting from the output port side an output field that is expected to be output from the output port 3-2 when an optical signal is launched into the input port 3-1. According to the field distributions 1 and 2, a spatial refractive index distribution is calculated such that the phase difference between the propagation light and reverse propagation light is eliminated at individual points (x, z) in the medium.Type: GrantFiled: December 25, 2003Date of Patent: July 8, 2008Assignee: Nippon Telegraph and Telephone CorporationInventors: Toshikazu Hashimoto, Ikuo Ogawa, Takeshi Kitagawa, Senichi Suzuki, Masahiro Yanagisawa, Tomohiro Shibata, Masaki Koutoku, Hiroshi Takahashi, Ryou Nagase, Masaru Kobayashi, Shuichiro Asakawa, Yoshiteru Abe, Tsutomu Kitoh, Takaharu Ohyama

Patent number: 7295746Abstract: In an optical connector for use in connecting an optical fiber, a shell member has an engaging portion. An internal member holds the optical fiber and is received in the shell member to be removable in a first direction. A stopper is engaged with the engaging portion in the first direction. A spring is engaged with the internal member and the stopper and urges the internal member towards a second direction opposite to the first direction. The shell member has a release operation portion for releasing the engaging portion from the stopper.Type: GrantFiled: April 1, 2005Date of Patent: November 13, 2007Assignees: Japan Aviation Electronics Industry, Limited, Nippon Telegraph and Telephone CorporationInventors: Yuichi Koreeda, Makoto Sanguu, Kiyoyuki Mutaguchi, Yoshiteru Abe, Masaru Kobayashi, Ryou Nagase

Patent number: 7241057Abstract: An optical connector apparatus includes a first and a second optical connector which are optically connectable to each other. The first optical connector includes a first connector body, a first light shielding device fitted to the first connector body in a first fitting direction, and a first guide portion coupled to the first light shielding device to guide fitting of the first light shielding device to the first connector body. The first guide portion has a first dimension in the first fitting direction. The second optical connector includes a second connector body, a second light shielding device fitted to the second connector body in a second fitting direction, and a second guide portion coupled to the second light shielding device to guide fitting of the second light shielding device to the second connector body. The second guide portion has a second dimension in the second fitting direction. In the optical connector, the second dimension is determined greater than the first dimension.Type: GrantFiled: March 1, 2006Date of Patent: July 10, 2007Assignees: Japan Aviation Electronics Industry, Limited, Nippon Telegraph and Telephone CorporationInventors: Yuichi Koreeda, Yoshiteru Abe, Masaru Kobayashi, Ryou Nagase

Patent number: 7149401Abstract: A disassembling tool includes a holding block having a housing portion for accommodating a plug connector, a slide block, and a handling part for sliding the slide block. The plug connector comprises an outer member and a plug frame and is accommodated in the housing portion of the holding block. When turning a handle of the handling part, the slide block is slidably moved so that projections provided on the slide block release the locking between locking portions of the outer member and locked portions of the plug frame. Following this, contact portions provided on the slide block come into contact with the plug frame so as to push it out of the outer member by a given amount.Type: GrantFiled: September 30, 2004Date of Patent: December 12, 2006Assignees: Japan Aviation Electronics Industry, Limited, Nippon Telegraph and Telephone CorporationInventors: Yuichi Koreeda, Makoto Sanguu, Kiyoyuki Mutaguchi, Yoshiteru Abe, Masaru Kobayashi, Ryou Nagase

Patent number: 5117528Abstract: To microscopically clean the ferrule end surface of an optical connector simply, uniformly and securely, the optical connector cleaner comprises a cleaning cloth woven with ultrafine fiber less than 0.1 denier; a casing formed with at least one opening for protecting the cleaning cloth from dust; and a mechanism for shifting the cleaning cloth exposed in the opening for cloth renewing, after the ferrule end surface has been rubbed with the cleaning cloth for cleaning. Further, it is preferable to provide an elastic member under the cleaning cloth for applying a constant cleaning pressure against the cloth and a guide member over the cleaning cloth for securely cleaning the ferrule end surface. The cloth shift mechanism is operated manually by the user or automatically by a motor.Type: GrantFiled: March 15, 1990Date of Patent: June 2, 1992Assignee: Nippon Telegraph and Telephone CorporationInventors: Kazunori Kanayama, Etsuji Sugita, Ryou Nagase, Shinichi Iwano
