Abstract: 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.

Abstract: 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.

Abstract: After the periphery of the magnetic sensitive element is surrounded by an elastic member, the magnetic sensitive element is mold-formed with resin material. Soft epoxy or gel resin is employed as the elastic member, poured in an element-mounting space and solidified. The magnetic sensitive element is surrounded by silicone rubber. Such construction allows the magnetic sensitive element not to be affected by vibration and allows the elastic member to absorb the stress which is created due to the thermal deformation of the molded resin.
