Patent number: 8677421Abstract: An object of the present invention is to provide a digital broadcast reception apparatus that allows a stable viewing even if a reception environment changes along with a movement. In the present invention, based on current position information indicating a current position detected by a current position detection section and broadcast area information stored in a broadcast area information storage section, a search-mode switching control section instructs a tuning control section to select a diversity operation mode if the current position is close to a boundary of a broadcast area, and select an independent reception operation mode if the current position is not close to the boundary of the broadcast area. In the diversity operation mode, a first system and a second system are tuned to the same physical channel, and cooperate with each other to demodulate a digital broadcast signal and a make an output through a diversity process.Type: GrantFiled: May 11, 2010Date of Patent: March 18, 2014Assignee: Mitsubishi Electric CorporationInventors: Keiichi Shirasuka, Kazuya Takaki

Patent number: 4729354Abstract: A fuel supply control system for use in an engine includes a feeder for supplying fuel to the engine in an amount suitable for operating conditions of the engine, a detector for detecting a decelerating state of the engine, and a correcting device for, upon detecting the deceleration, increasing a rate of fuel supply so that combustion may be stabilized to prevent car-bucking. The system further includes a brake detector for detecting an operative state of a brake device of the vehicle, and a limiter for, upon operation of the brake device, limiting the increase of fuel supply whereby the fuel consumption efficiency can be improved. During operation of the break device, car-bucking is restricted by a braking force so that substantially no vibration is transmitted to a driver.Type: GrantFiled: March 2, 1987Date of Patent: March 8, 1988Assignee: Mazda Motor CorporationInventors: Hideki Tominaga, Kazuya Takaki
