摘要： A rotation angle detecting device is rotated by a rotating object via a gear mechanism to detect a rotation angle of the rotating object. The rotation angle detecting device includes a housing, a magnet rotor unit having a permanent magnet and a central hole, a magnetic sensor unit including a pair of magnetic sensor elements each of which detects magnetic flux density of a magnetic field generated by the permanent magnet in a direction different from the other, and a signal processor that calculates a rotation angle of the rotating object from the magnetic flux density. The magnetic rotor unit includes a mechanism for changing the magnetic flux density as the number of turns of the magnet rotor unit changes.

摘要： A rotation angle of a shaft is detected based on changes in levels of magnetic flux from a single magnet that is mounted on the shaft and is moved axially in accordance with rotation of the shaft. Respective detected variations in level of X-direction and Y-direction magnetic flux components (each at right angles to the shaft axis) are used to obtain a first quantity that varies monotonically, and a second quantity that varies periodically, in accordance with increased rotation angle. An accurate value of the shaft rotation angle is calculated based on the first and second quantities, in combination.

摘要： A rotation angle detecting device includes a columnar permanent magnet that has a generally ring-shaped cross-section and a pair of magnetic poles, a pair of semi-cylindrical yokes disposed in a circumferential direction opposite the permanent magnet, a rotary shaft fixed to the permanent magnet at a shifted rotation axis and a magnetic sensor disposed in one of circumferential gaps between the yokes. The rotation axis and the magnetic poles are arranged so that the magnetic flux density becomes maximum at portions of the yoke less than 90 degrees angled from the circumferential gap in which the magnetic sensor is disposed.

摘要： A relay (20) receives a battery information acquisition time from each battery module (10) and calculates measurement time differential information Δt, that is, a time difference between the battery information acquisition time as a reference and the battery information acquisition time of another battery module (10) among the received battery information acquisition times, for each battery module (10). A measurement time correction unit (115) of each battery module (10) corrects a measurement time by the measurement time differential information Δt, using the measurement time differential information Δt received from the relay (20) to adjust the battery information acquisition time of each battery module (10) to the same time.

摘要： A turbine wheel of a turbocharger has a turbine blade. The turbine blade has a fin shape of which width in the rotation direction of the turbocharger is narrow, and is projected from the base portion of the turbine wheel. An inclined part of the turbine blade is inclined with respect to the rotation direction of the turbocharger. A coil is disposed so that the inclined part passes nearby as the turbine wheel rotates in a posture that an end in the center axis direction is directed toward the turbocharger. A detector detects a change in inductance, which occurs when the inclined part of the coil passes nearby.
