摘要： In a brushless motor of the kind not employing a sensor for detecting rotor position, a rotational reference position of the rotor is detected based on an induction voltage in a stator excitation coil, and an energization switching point of the stator excitation coil is determined to occur a delayed time from the reference position. The time delay is increased or decreased in response to the rotational speed of the motor, so that energization switching of the excitation coils is performed at the optimum position in accordance with corresponding changes in the rotational speed of the motor. Signal masking is performed so that noise generated by the excitation coil switching does not interfere with the detection of the rotor reference position.

摘要： A cam timing control device in an antomotive engine which used in a valve timing correcting device of a type wherein an electromagnetic force is used to change a cam timing. The cam timing control device is so designed that, in the event that a resistance to the change of the cam timing is high, the length of time during which an electric power is continuously supplied to the electromagnetic coil is prolonged.

摘要： An automatic equalizer for use with a recording and/or reproducing apparatus or with a communication transmission channel, wherein equalizer parameters are rendered variable and the degree of change of the error rate is extracted to set the parameters to optimum values based on the degree of change of the error rate. Output signal error rates are sequentially detected at a plurality of measurement points corresponding to preset plural characteristic parameters to find a minimum error rate measurement point. An initial parameter setting operation is performed for providing characteristic parameters for this measurement point to the equalizer as the initial parameter.

摘要： A valve timing control system for varying a valve timing determines whether an engine operating condition falls within a specific valve timing range established for a specific valve timing or a standard valve timing range, other than the specific valve timing range, established for a standard valve timing. A valve timing device is activated so as to change a valve timing to the standard valve timing when the engine operates in the standard valve timing range. The valve timing device is also deactivated so as to change a valve timing to the specific valve timing when the engine operates in the specific valve timing range.

摘要： A fuel control system for an engine has a fuel injector which injects fuel into an intake manifold of the engine. A fuel injector controller determines the amount of fuel to be injected from the fuel injector so that the sum of the amount of the direct delivery part of the injected fuel which is directly fed to a combustion chamber of the engine from the injector and the amount of the drawn part fuel which has adhered to the well surface of the intake manifold, evaporates and then flows into the combustion chamber is a target amount of fuel to be actually fed to the combustion chamber and causes the fuel injector to inject the target amount of fuel. When the controller increases the amount of fuel to be injected during acceleration, the amount of part of fuel injected from the injector which part is robbed by the wall surface of the intake manifold near the injector and does not contribute to the air-fuel ratio in intake air fed to the combustion chamber during acceleration is estimated, and the fuel injector controller increases the amount of fuel increase by an amount corresponding to the estimated amount of the part of fuel which is robbed by the wall surface of the intake manifold near the injector and does not contribute to the air-fuel ratio in intake air fed to the combustion chamber.
