摘要： A potentiometer includes a magnetoresistive element made of ferromagnetic material. A device applies a magnetic field to the magnetoresistive element. An absolute value of the magnetic field applied to the magnetoresistive element is equal to or greater than a saturation magnetic field with respect to the ferromagnetic magnetoresistive element. The magnetic field applying device is movable relative to the magnetoresistive element.

摘要： When applying a bias field in the direction of the easy axis of magnetization of a signal field-detecting MR element assembly, a leakage magnetic field of a magnetic recording medium adapted to generate a signal field is applied as the desired bias field without using any exclusive bias field application device. The magnetic recording medium and the thin-film MR element assembly are arranged in a manner that they make a predetermined angle.

摘要： A vibratory angular rate sensor comprises a vibrator having a vibrating element arranged to oscillate along a first direction, the element being arranged to further oscillate along a second direction perpendicular to the first direction when subjected to angular rate about a third direction perpendicular to the first and second directions. The vibrating element is caused to oscillate at a predetermined frequency along the first direction. An oscillation detector generates a voltage representing oscillations of the vibrating element along the second direction. A first synchronous detector synchronously detects a primary frequency component of the generated voltage using clock pulses of the predetermined frequency to produce an output signal. A second synchronous detector synchronously detects an odd-numbered harmonic of the generated voltage using clock pulses of the odd-numbered harmonic frequency. A residual odd-numbered harmonic component contained in the output signal of the first synchronous detector is cancelled with the detected odd-numbered harmonic.

摘要： A switching apparatus is provided which may be used for power window control systems of automotive vehicles. The switching apparatus includes an operating knob, a magnet, a magnetoresistive element, and a position determining circuit. The operating knob is manually shifted between a plurality of switching positions. The magnet moves according to the movement of the operating knob. The magnetoresistive element is placed in a magnetic field applied from the magnet and changes an electrical resistance thereof according to a variation in orientation of a magnetic flux applied to the magnetoresistive element resulting from the movement of the magnet. The position determining circuit monitors a change in electric resistance of the magnetoresistive element to determine the switching position of the operating member.
