摘要： A PLL frequency synthesizer includes a reset circuit which determines whether or not an oscillator starts to normally generate an oscillation signal in response to a power save signal which intermittently operates the oscillator in a standby mode and which outputs a reset signal to a prescaler when it is determined that the oscillator normally generates the oscillation signal. A hold circuit prevents a frequency-divided signal being output from the prescaler to a programmable counter and an initial phase detection circuit until the prescaler is reset to an initial state in response to the reset signal and starts to normally generate the frequency-divided signal.

摘要： The present invention provides a valve timing regulating device which controls the opening/closing timing of an exhaust valve of an internal engine combustion engine so that upon starting the engine a rotor member is rotated relative to a housing member for reaching in shorter time duration a region in which a lock mechanism functions. The valve timing regulation device includes a fluid pressure circuit controlling the supply and drainage of operating fluid to and from each of the advance angle fluid chamber and the retard angle fluid chamber. The fluid pressure circuit has a fluid pump driven by the internal combustion engine, a control valve controlling, by adjusting the operating fluid supplied from the fluid pump, the supply and draining of operating fluid to and from each of the advance angle fluid chamber and the retard angle fluid chamber, and a check valve disposed between the control valve and the fluid pump such that the check valve is placed close to the control valve for preventing entrance of the operating fluid into the fluid pump.

摘要： A variable valve timing system is provided with a relative rotation controlling mechanism allowing relative rotation of the housing member and the rotor member by an unlock operation through the supply of operation fluid, and restricting the relative rotation of the housing member and the rotor member at an intermediate angle phase between a most retarded angle phase and a most advanced angle phase by a lock operation through the discharge of the operation fluid. A hydraulic pressure circuit controls the supply and discharge of the operation fluid to the relative rotation controlling mechanism and also controls the supply and discharge of the operation fluid to the advanced angle chamber and the retarded angle chamber. The hydraulic pressure circuit is adapted to discharge the operation fluid from the advanced angle chamber, the retarded angle chamber and the relative rotation controlling mechanism when the combustion engine is started.
