Patent number: 9189724Abstract: The present invention provides a noncontact interface technique capable of performing communication operation without stopping an internal operation even when a clock signal cannot be extracted from a carrier wave. In a semiconductor device that receives a modulated carrier wave from an antenna, generates an internal clock signal on the basis of a clock signal extracted from the received carrier wave, and performs operation synchronously with the internal clock signal, a PLL circuit that receives the extracted clock signal and generates the internal clock signal is provided with a voltage control oscillation function. In the case where the clock signal extracted from the carrier wave is discretely interrupted, the function makes the internal clock signal maintained at a frequency immediately before the interruption. With the configuration, even when the clock signal extracted from the carrier wave is interrupted, internal data processes such as decoding and bus interfacing can be continued.Type: GrantFiled: November 18, 2014Date of Patent: November 17, 2015Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Shin Morita, Norihisa Yamamoto

Patent number: 9028076Abstract: In a projector, a projection unit includes a projection mechanism that projects an image and an air hole that takes in or exhausts air used to dissipate heat generated from a light source included in the projection mechanism. A housing covers the air hole when the projection unit is in a storage position in which the projection unit does not project an image and uncovers the air hole when the projection unit is in a projection position in which the projection unit projects an image. The drive mechanism moves the projection unit or a cover member. An electronic control unit controls the drive mechanism to move the projection unit to the projection position in which an image is projected when receiving a predetermined projection preparation request and move the projection unit to the storage position in which no image is projected when receiving a predetermined storage request.Type: GrantFiled: June 29, 2012Date of Patent: May 12, 2015Assignee: JVC Kenwood CorporationInventors: Ryo Nishima, Norihisa Yamamoto, Kouichi Kawamura
