Patent number: 10168277Abstract: A photodiode includes semiconductor layers and a gate insulating layer provided on a buried insulating layer formed on a substrate and has a diffraction grating portion in which a plurality of groove portions are formed in a two-dimensional lattice shape, on the gate insulating layer. Measurement light is guided by an optical system including a photoelastic modulator and is incident on the photodiode. The measurement light is emitted from the light source device in a state of being linearly polarized light having a predetermined wavelength and is converted at a predetermined frequency by the optical system such that states in which the measurement light becomes linearly polarized light beams of two orthogonal directions are repeated. In addition, electric signals from the photodiode in the state in which the measurement light becomes the linearly polarized light beams of the two orthogonal directions are lock-in detected.Type: GrantFiled: February 10, 2016Date of Patent: January 1, 2019Assignees: NATIONAL UNIVERSITY CORPORATION SHIZUOKA UNIVERSITY, YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Hiroshi Inokawa, Hiroaki Satoh, Atsushi Ono

Patent number: 6283242Abstract: A compact air cleaner for a motorcycle engine has its intake duct directed in a widthwise direction of the motorcycle. The air cleaner includes an air cleaner case, an air cleaner element and a case cover. The air cleaner element partitions an inner portion of the air cleaner case and case cover into a clean room and a dirty room. The air cleaner element extends in the motorcycle's travel direction. An intake port communicates with the dirty room and opens to a space surrounded by a rear face of the clean room, a front portion of a rear fender and a bottom portion of a seat.Type: GrantFiled: September 10, 1999Date of Patent: September 4, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Akio Umeoka, Hiroshi Inokawa

Patent number: 5213991Abstract: In a method of making a MOSFET-type semiconductor device of this invention, a surface of a semiconductor substrate is covered in a predetermined pattern with an insulating layer comprising a silicon-nitride-containing film or with an insulating layer whose top surface and side surfaces bear a silicon-nitride-containing film, thereby forming on the semiconductor substrate a recess region at which the semiconductor substrate is exposed. An epitaxial silicon film and polycrystalline silicon film are formed simultaneously on the exposed semiconductor substrate and on the insulating film, respectively. A whole channel region and a part of source and drain diffused-layer regions are formed in the epitaxial silicon film, and source and drain diffused-layer regions are formed in the polycrystalline silicon film. A gate electrode of this MOSFET-type semiconductor device may be formed at the recess region by a self-align method.Type: GrantFiled: March 24, 1992Date of Patent: May 25, 1993Assignee: Nippon Telegraph and Telephone CorporationInventors: Hiroshi Inokawa, Toshio Kobayashi, Kazuhide Kiuchi
