摘要： A stepping motor includes a rotor formed of ferromagnetic material having a plurality of circumferentially alternately arranged poles of opposite polarities and a stator having main poles which are polarized in opposite polarities by successive drive pulses of opposite senses. An auxiliary stator pole is provided between adjacent main stator poles to give rise to a thrust that causes the rotor to rotate a small angle in the direction of rotation during the interval between successive drive pulses so that upon polarization of the stator by a subsequent drive pulse the rotor is easily caused to rotate in the same direction of rotation.

摘要： A laser-radar type distance measuring equipment for a motor vehicle is shown, which comprises a probe unit including a laser emitting device and a reflected laser receiving device. The probe unit is mounted on the vehicle body. A steering angle sensor is used for producing an information signal representative of the steered angle of the vehicle. A so-called performance changing device is employed for changing the performance of the probe unit. A control unit controls the performance changing device in accordance with the information signal issued from the steering angle sensor.
