20090054024 | Radio receiver device - A radio receiver device includes a radio signal processing section and a digital processing section. The radio signal processing section converts a received radio signal into a digital signal, demodulates the digital signal and detects a S/N ratio of the radio signal. The digital processing section digitally processes digital signals and switches over its operation mode based on the detected S/N ratio, thereby controlling a digital noise generated in the digital processing. The radio processing section checks whether the S/N ratio is lowered by a digital noise of the digital processing section or a shielding body external to the radio receiver device. The digital processing section switches over its operation mode to reduce the digital noise only when the cause of the fall of the S/N ratio is caused by the digital noise. | 02-26-2009 |

20130213365 | FUEL VAPOR LEAKAGE SENSING APPARATUS AND FUEL VAPOR LEAKAGE SENSING METHOD USING THE SAME - An operation of a change valve is changeable between a valve closing state, in which the change valve is closed to close connection between a pump passage and a canister passage and to open connection between an atmosphere passage and the canister passage, and a valve opening state, in which the change valve is opened to open the connection between the pump passage and the canister passage and to close the connection between the atmosphere passage and the canister passage. An ECU determines that the change valve is abnormal when a value, which is obtained by subtracting a second reference pressure measured in an (n-1)th execution of a fuel vapor leakage sensing process from a first reference pressure measured in an nth execution of the fuel vapor leakage sensing process, is equal to or larger than a predetermined threshold value. | 08-22-2013 |
20140299081 | VALVE TIMING CONTROL APPARATUS - A valve timing control apparatus includes a temperature sensing member which expands at a main lock phase when a temperature of an engine is higher than or equal to a predetermined temperature so as to prohibit a main lock component from moving out of a main lock hole to a guide slot. The temperature sensing member shrinks at the main lock phase when the temperature of the engine is lower than the predetermined temperature so as to allow the main lock component to move out of the main lock hole toward the guide slot. | 10-09-2014 |
