Abstract: PURPOSE:To enable to judge the possibility of stable starting with excess margin by calculating the temperature of a rotor by monitoring a stator current. CONSTITUTION:The output of a current transformer 3 for detecting a current supplied to a motor is converted by an A/D converter 4 to a digital signal, and the temperature T(t) of a rotor is always calculated at a time (t) by a calculator 6 on the basis of the output of the converter 4. When the measured value of the AC current exceeds an aligned starting current value, whether the total temperature rising value produced by adding the predetermined rising starting temperature value DELTAT to the rotor temperature T(t) of the motor 1 exceeds the predetermined allowable temperature rising value or not is judged. When the total temperature rising value exceeds the allowable temperature rising value, a restart stop signal is output.

Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a failure diagnostic device which can easily diagnose a failure of an actuator before its operation is stopped. SOLUTION: The operating time of an actuator is calculated from the start and the end of operation of the actuator (110-130) and the normal operating time of the actuator that is previously measured is read (140).

Meanwhile, a light failure is judged when the difference is small between both operating times (170). This decision may be also obtained on the basis of the drive power value in place of the operating time.

The state (c) indicates the distorted image of a front pin state in which the image is distorted to the inner side near the center of the image pickup region.  The focusing detection or the driving to the automatic focusing is resulted if the distortions are detected by a focusing detecting element and are compared before and after the movement of the imaging lens and the imaging lens is moved so as to eliminate the distortions.
