Abstract: A controller determines the state of the range detector on the basis of the detection signals detected by the range detector, then when the range detector is determined to be in an abnormal condition, the controller moves the shift-changing valve until the movement is inhibited by the restriction member, thereby establishes the position of one end, and controls the actuator with respect to the established one end position and on the basis of the amount of operation to move the shift-changing valve to the position corresponding to an instructed shift range. Even when the range detector is in an abnormal condition, it is possible to make a change to the shift range corresponding to a shift range changing command.

Abstract: By utilizing a mechanical backlash generated between an electric actuator and a shift range switching mechanism, a specific region is obtained, in which a variation in the output shaft angle is relatively small with respect to a variation in rotor angle. In this specific range, an actual shift range position is calculated, whereby the rotor angle that the motor controller recognizes is corrected so as to relate the actual shift range position. A deviation between the rotor angle and the actual shift range is corrected, so that the shift range switching is precisely performed.

Abstract: A position shift control apparatus is provided which includes an electrical motor joined to an object through an output shaft and a torque transmission mechanism, a detent mechanism producing elastic pressure to hold the object at a target position, and a motor controller. When torque, which is created by the elastic pressure produced by the detent mechanism and acts on the output shaft during rotation of the motor, is opposite in orientation to that outputted by the motor, the motor controller determines the angular position of the motor, as sampled upon a change in an output from an output shaft position sensor, as a reference angular position of the motor for use in controlling the position of the motor, thereby resulting in a decrease in mechanical load on the detent mechanism and the torque transmission mechanism to ensure the durability and operation accuracy of the apparatus.

Abstract: A flat acoustic conversion device includes two magnets disposed so that their magnetic poles face upward arid are adjacent to or in contact with one another, and the magnetic pole faces of different polarities arc disposed alternately; a vibrating member disposed on the top surface of the yoke; coil pairs wound in helical form and disposed at front and reverse surfaces of the vibrating membrane; such that magnetic flux traveling in a direction substantially parallel to a surface of the vibrating membrane becomes a maximum, and interlinks with the coil pairs. When current is supplied to the coils, a direction of force which the current receives from a magnetic field is substantially orthogonal to the surface of the vibrating membrane, and force in a direction along the surface of the vibrating membrane becomes extremely low. Thus, noise components can be reduced such that sound quality can be improved.
