摘要： A position sensor includes a longitudinally extending permanent magnet member at least two longitudinally extending arc-shaped projecting elements respectively projecting from the opposite ends toward the inside space to confront each other at a distance and a pair of compatible main magnetic sensors disposed in the inside space along the longitudinal axis at an interval so as to generate a pair of output signals when the permanent magnet member shifts along the longitudinal axis. The opposite ends of the permanent magnet member are configured to surround a common inside space and polarized to have opposite magnetic poles so as to provide in the inside space a magnetic field whose magnetic flux density becomes a maximum at a longitudinal center of the inside space and gradually becomes smaller as a position of the inside space shifts from the longitudinal center along a longitudinal axis of the permanent magnet members. The arc-shaped projecting elements are arranged so that the magnetic flux density and each of the output signals can be expressed by a cosine of a shift value from the longitudinal center, and the interval is ¼ of the cycle of the cosine.

摘要： A linear displacement detection apparatus is configured to convert a linear displacement of a shaft into a rotary displacement of a sensor rotor of a rotary displacement sensor so as to detect the linear displacement. A sensor lever is fixed to the sensor rotor and rotatable about an axis of the sensor rotor. A sensor rod is located closer to the shaft than the sensor lever and configured to transmit the linear displacement of the shaft to the sensor lever. A bearing member is located closer to the shaft than the sensor rod and configured to release rocking of the shaft.

摘要： A liquid mixing ratio detecting apparatus is designed so that an oscillation voltage generated by an oscillation unit is applied to one of a differentiating circuit and an integrating circuit, which is constituted by a combination of a capacitor composed of a pair of opposite electrodes for detecting a mixing ratio of a mixed liquid and a resistor, and a mixing ratio detecting unit produces a signal relating to an inclination rate of one of a differential waveform signal and an integration waveform signal, which is generated by one of the differentiating circuit and the integrating circuit, respectively, thereby obtaining a signal representing the mixing ratio of the mixed liquid on the basis of the produced signal relating to the inclination rate of the waveform signal.
