Patent number: 8773253Abstract: A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits a movement notification sound to outside of a vehicle to inform a person in an area surrounding the vehicle that the vehicle is moving at a low speed. The notification sound control device operates the sound emitting device to selectively emit the movement notification sound. The notification sound control device includes a notification sound prohibiting section and a prohibition cancelling section. The notification sound prohibiting section prohibits an emission of the movement notification sound by the sound emitting device. The prohibition cancelling section cancels a notification sound emission prohibition imposed by the notification sound prohibiting section either upon a vehicle speed of the vehicle exceeding a prescribed vehicle speed or based on position information of the vehicle.Type: GrantFiled: February 7, 2011Date of Patent: July 8, 2014Assignee: Nissan Motor Co., Ltd.Inventors: Hideo Yoshino, Tsuyoshi Kanuma, Yoshiro Tateishi, Hironori Saito, Katsumi Kimura

Patent number: 8404547Abstract: Provided is a manufacturing method for an offset MOS transistor capable of operating safely even under a voltage of 50 V or higher. In the offset MOS transistor which includes a LOCOS oxide film, the LOCOS oxide film formed in a periphery of a drain diffusion layer, in which a high withstanding voltage is required, is etched, and the drain diffusion layer is formed so as to spread into a surface region of a semiconductor substrate located below a region in which the LOCOS oxide film is thinned. As a result, end portions of the drain diffusion layer are covered by an offset diffusion layer, whereby electric field concentration occurring in a region of a lower portion of the drain diffusion layer can be relaxed.Type: GrantFiled: July 28, 2009Date of Patent: March 26, 2013Assignee: Seiko Instruments Inc.Inventors: Yuichiro Kitajima, Hideo Yoshino

Publication number: 20120228721Abstract: In a gate electrode (40) provided on a gate insulating film (30), a depletion layer (42) is formed at a junction surface between a P-type semiconductor layer (41) and a gate insulating film (30). Since a region of the depletion layer (42) inside the gate electrode (40) changes due to temperature change, inducing a change in an effect of a gate voltage to channel formation, a threshold voltage changes to a larger extent than in a case of a typical MOS transistor. This is used to control the MOS transistor to have a desired temperature characteristic. A temperature compensation circuit may be eliminated and the circuit scale may be reduced.Type: ApplicationFiled: March 8, 2012Publication date: September 13, 2012Inventor: Hideo YOSHINO
