    摘要: A device for controlling an amount of light of a lighting unit for use in an endoscope, used to view an image of an object. The device includes a light shield for shielding light generated by a light source and transmitted to the endoscope. A stepping motor drives the light shield for a series of predetermined time intervals. Brightness of the image is detected during each of the time intervals and a predetermined number of pulses are generated during each of the time intervals. An angular position of the light shielding system is determined and the phase of excitation of the motor is varied in response to the angular position. The pulses generated are used to drive the stepping motor in each of the plurality of time intervals.

    摘要: An apparatus for displaying monitoring data of a continuously varying operation condition of a drive mechanism driven by an actuator, in which data of one operation cycle of the drive mechanism is detected preliminarily as reference data and displayed on a coordinate axis on a monitor to show deviation between the reference data and the detected data of each operation cycle. Allowable uppermost and lowermost limit data of the reference data are also calculated and displayed on the same coordinate axis of the displaying surface of the monitor.
