Patent number: 8758087Abstract: In a wafer processing method, an ingot is sliced into a wafer and the wafer is planarized by polishing a surface of the wafer. When the wafer is planarized, the wafer is disposed on a wafer holder and the wafer is rotated, a heat quantity is applied to a portion of the wafer so as to form a reformed layer at the portion of the wafer, and a polishing tool is brought into contact with the portion of wafer while rotating so as to polish the portion of the wafer.Type: GrantFiled: May 24, 2011Date of Patent: June 24, 2014Assignee: DENSO CORPORATIONInventors: Kyohei Koutake, Hiromichi Morita, Fumiyoshi Kano, Tetsuji Yamaguchi, Sumitomo Inomata, Masatake Nagaya

Patent number: 7732784Abstract: An OCT technique that permits tomographic observation of biological body parts that are difficult to restrain, and also provides a tomographic observation technique for the observation of a constrainable part that does not require constraint and thus removes a burden on the biological body. A wavelength-tunable light generator (wavelength-tunable light source) is employed as the light source of the optical coherence tomography device. The wavelength-tunable light generator has a wave number tunable range width of at least 4.7×10?2 ?m?1 and an emitted-light frequency width of no more than 13 GHz, for example, and is capable of changing the wave number stepwise at wave number intervals of no more than 3.1×10?4 ?m?1 and time intervals of no more than 530 ?s.Type: GrantFiled: October 5, 2007Date of Patent: June 8, 2010Assignee: School Juridical Person Kitasato InstituteInventors: Kimiya Shimizu, Kohji Ohbayashi, Takuji Amano, Hideaki Hiro-Oka, DongHak Choi, Hiroyuki Furukawa, Motoi Nakanishi, Fumiyoshi Kano, Takeo Miyazawa, Ryoko Yoshimura

Patent number: 5325392Abstract: The distributed reflector includes a substrate and at least one optical waveguide formed on the substrate and having a refractive index larger than the substrate and at least one optical confinement layer having a refractive index smaller than the optical waveguide layer. A diffractive grating is formed in at least one layer constituting the optical waveguide. The diffractive grating has a structure of which at least one parameter defining optical reflectivity varies depending on its position, and is formed continuously for at least two periods, the period being approximately defined by the length of repeating unit region. The parameter may be pitch, coupling coefficient, bandgap composition, phase shift, etc. The semiconductor laser includes the distributed reflector which may be of a distributed reflector type or distributed feed back type and has distributed reflector regions and a phase adjustment region.Type: GrantFiled: March 3, 1993Date of Patent: June 28, 1994Assignee: Nippon Telegraph and Telephone CorporationInventors: Yuichi Tohmori, Yoshikuni, Hiroyuki Ishii, Fumiyoshi Kano, Toshiaki Tamamura
