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 permanent magnet is fixed to a stationary portion. A yoke made of magnetic material is provided to a rotating portion. The yoke is tube-shaped to surround the permanent magnet and has a chord portion into which a magnetic flux generated by the permanent magnet preferentially flows. The chord portion is arranged in such a manner as to be close to the permanent magnet. A Hall element is arranged at a specified position of the stationary portion relative to the permanent magnet 20. The Hall element outputs a signal which corresponds to a density and an angle of a magnetic flux generated between the chord portion and the permanent magnet.

摘要： A magnetic sensing surface of a stroke sensor is placed in an angular range between a first imaginary line and a second imaginary line. The first imaginary line is an imaginary line that coincides with a center line between first and second magnets of a magnetic movable body when a wastegate valve is placed to have a full close degree of the wastegate valve. The second imaginary line is an imaginary line that coincides with the center line between the first and second magnets when the wastegate valve is placed to have a half degree between the full close degree and a full open degree of the wastegate valve.

摘要： A rotational angle detecting device includes a magnetic member, a magnetic sensor and a processing unit. The magnetic sensor includes a sensor element disposed to rotate relative to the magnetic member in accordance with a rotation of a rotating object and outputting signals according to a change in a magnetic field caused as rotating relative to the magnetic member. The processing unit is capable of processing output values of the sensor element. The processing unit acquires the output value at every angle of rotation of the rotating object, estimates a waveform for one cycle of the signals as an estimation waveform from the acquired output values, and normalizes an amplitude of the estimation waveform. Further, the processing unit calculates a rotational angle of the rotating object by a trigonometric function operation based on the output value and the normalized amplitude.
