摘要： A first sensor element outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element outputs a second output signal associated with the first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A first conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into a signal representing the rotation angle of the motor.

摘要： A small-sized and low-cost phase detection circuit which has improved noise immunity. The phase detection circuit comprises a multiplier for multiplying an input signal by a reference signal and outputting a first signal, an integration circuit for integrating the first signal and outputting a second signal, a phase estimation circuit for estimating phase information based on the second signal, and a reference signal generation circuit for generating the reference signal based on the estimated phase information. Since the phase is detected based on information representing an entire waveform, the influence of local noise can be diluted and noise immunity can be improved.

摘要： A highly accurate displacement sensor using GMR elements for detecting a displacement of a physical quantity such as angle is to be provided wherein a waveform distortion of output voltage is diminished.There are installed at least two Wheatstone bridge circuits having a predetermined angular offset and each comprising a plurality of GMR elements, the GMR elements each having a fixed magnetic layer set to a predetermined magnetization direction. An AC power supply is use as a power supply of the Wheatstone bridge circuits and a displacement of a physical quantity such as a rotational angle is detected on the basis of AC-modulated outputs from the Wheatstone bridge circuits.An anisotropic self-bias effect of a free magnetic layer in each GMR element can be diminished and hence it is possible to remedy a waveform distortion of an output signal based on the anisotropic self-bias effect of the free magnetic layer.

摘要： A system for directly measuring tire grip conditions is provided which can measure a skidding condition with no need of applying a vibration. A tire rotation speed sensor comprising a detection gear and a magnet sensor is mounted to a rotating shaft of a tire. An output of the tire rotation speed sensor is analyzed in time-frequency domain to detect vibrations caused by slips, thereby determining tire grip conditions, such as a slip ratio and a slip angle. By detecting fluctuations in rotation based on the cause-effect relation between the occurrence of tire slips and the occurrence of fluctuations in rotation, the tire slips can be directly detected. Therefore, the tire grip conditions can be confirmed with high accuracy.

摘要： An engine electronic control unit is inserted through a through hole provided in an intake pipe and mounted in an intake air passage in a direction substantially perpendicularly with respect to a plane of the intake pipe forming the intake air passage. This unit is then secured to the intake pipe using a fixing flange provided at a connector portion. A fixing rail is protruded inside the intake pipe and leading edges of a metal base and a metal cover of the unit are inserted into this rail, thereby securing in position an end opposite to a side of the connector portion of the unit. This realizes an engine electronic control unit offering an outstanding heat radiation performance and vibration resistance, without having to provide special heat radiating parts or without involving an increase in an intake air resistance within the intake air passage. By using such an engine electronic control unit, it is possible to provide a low-cost, compact engine air intake system.
