Patent number: 7317658Abstract: A semiconductor integrated circuit has a memory which can enter active state or standby state, and the memory has voltage generation circuits for bit lines and source lines with which memory cells are connected. The voltage generation circuits make the potential of the bit lines and the potential of the source lines equal to each other in response to an instruction to transition from active state to standby state. The voltage generation circuits produce a potential difference between the bit lines and the source lines in response to an instruction to transition from standby state to active state. In standby state, the potential of the bit lines and that of the source lines are equal to each other. Therefore, sub-threshold leakage does not occur between the source and drain of each memory cell. In active state, the source line potential is not varied.Type: GrantFiled: March 17, 2006Date of Patent: January 8, 2008Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Yoshio Takazawa, Toshio Yamada, Shinichi Ozawa, Takeo Kanai, Minoru Katoh, Koudou Yamauchi, Toshihiro Araki

Patent number: 5796430Abstract: When defective pixels of a solid state image pickup device of a video camera are corrected by signal processes, a white spot noise is detected by closing an iris and by comparing the signal level and a level of only a dark current. Further, in this case, a gain of an AGC circuit for controlling a gain of a video signal is raised and a precise detection is executed. By executing such a detecting operation at the time of turn-on or turn-off of a power source, the user is not annoying. In the ordinary photographing, a reference level in detection of a white spot noise is set to an optimum value in accordance with a temperature of the solid state image pickup device or its peripheral temperature or the gain of the AGC circuit so that the white spot noise detection is not influenced by the temperature of the solid state image pickup device or the operating state of the AGC circuit.Type: GrantFiled: January 27, 1997Date of Patent: August 18, 1998Assignee: Hitachi, Ltd.Inventors: Minoru Katoh, Kenji Itoh, Hiroyasu Ohtsubo

Patent number: 5787318Abstract: A camera in which lenses in a lens system can be easily adjusted and manufacturing steps can be eliminated. The camera is equipped with an aperture which regulates the exposure region of a film, and a pressure plate with a tool insertion aperture hole formed in a region opposite the aperture. The tool insertion hole is disposed at the back surface of the aperture. This tool insertion hole allows for easy and efficient adjustment of the lenses making up the camera's lens system. Usually, the lens system is a zoom lens system.Type: GrantFiled: November 12, 1997Date of Patent: July 28, 1998Assignee: Nikon CorporationInventors: Minoru Katoh, Hiroshi Wakabayashi, Kiyosada Machida

Patent number: 5734943Abstract: To avoid making a device body larger through positioning of a rotation shaft of a cartridge cover, a device having a device body containing a cartridge chamber into which a film cartridge can be inserted and removed in a axial direction, a cartridge cover provided on the device body which opens and closes the cartridge chamber by rotating about a predetermined axis of rotation, and a device-composing component positioned to the side of the cartridge chamber to extend in a first direction orthogonal to the direction of insertion and removal of the cartridge, the axis of rotation of the cartridge cover extends in a second direction inclined to the first direction from a position near device-composing component. The positioning of the axis of rotation of the cartridge cover in the camera body and not along an edge or corner also improves the camera's aesthetic and ergonomic qualities.Type: GrantFiled: March 25, 1996Date of Patent: March 31, 1998Assignee: Nikon CorporationInventors: Minoru Katoh, Kiyosada Machida, Junichi Omi
