Patent number: 8837895Abstract: A fiber holder which can wind an optical fiber easily and accurately, and hold an optical fiber in a wound state is provided. The optical fiber is accommodated in the groove (introduction portion) formed on the fiber bobbin, after that, the bobbin cover is rotated in the rotational direction of the helical groove while the optical fiber is kept in contact with the cutout formed in the bobbin cover. With this, the optical fiber can be accommodated in the groove. Thus, the optical fiber can be wound easily and accurately, and the optical fiber can be held on the fiber bobbin.Type: GrantFiled: May 23, 2012Date of Patent: September 16, 2014Assignee: Omron CorporationInventors: Fumihiko Nakano, Tadamasa Yokoi, Yuichi Ishizu, Masao Yoshioka

Publication number: 20140198377Abstract: A single mode semiconductor laser includes a first optical resonator, which is formed by a total reflection surface and a partial reflection surface. Light emitted from the partial reflection surface of the single mode semiconductor laser enters a fiber Bragg grating, which includes a diffraction grating formed therein. The diffraction grating forms a second optical resonator in combination with the total reflection surface of the single mode semiconductor laser. A fiber amplifier amplifies a laser beam emitted from the fiber Bragg grating.Type: ApplicationFiled: December 9, 2013Publication date: July 17, 2014Applicant: OMRON CORPORATIONInventors: Masao YOSHIOKA, Takuya TOGAWA

Patent number: 8398813Abstract: The present invention provides a processing apparatus and a processing method, both of which can carry out a low-temperature process to allow active gas species to react with an oxide film on an object to be processed to form a product film and a heating process to heat the object to a predetermined temperature to evaporate the product film, in succession. This processing apparatus 12 is provided with a shielding plate 103 capable of entering a gap between the object W and a transparent window 28 and also withdrawing from the gap. On condition that the shielding plate 103 is closed to cut off irradiation heat from the transparent window 28, the product film is formed by allowing the active gas species of NF3 gas to react with a native oxide film on the object under the low-temperature condition. After that, upon closing the shielding plate 103, the native oxide film is removed by applying heat irradiated from a heating lamp 36 to the product film through the transparent window 28.Type: GrantFiled: October 31, 2007Date of Patent: March 19, 2013Assignee: Tokyo Electron LimitedInventors: Yasuo Kobayashi, Masao Yoshioka
