    摘要: A charge control circuit for a battery charger has a sensor circuit for sensing the temperature of a battery being charged and providing an output indicative thereof. A differentiator circuit converts the output of the sensor circuit into an instantaneous time derivative of thereof which is indicative of a corresponding temperature gradient of the battery. When the time derivative is determined by a judging circuit to be below a predetermined threshold indicative of the battery reaching its full charge state, the judging circuit responds to provide a first control signal, causing the battery charger to charge the battery at a high rate. Once the time derivative exceeds the threshold, the judging circuit provides a second control signal, causing the charger to terminate the high rate charge and change to a trickle charge or zero rate charge.

    摘要: The perimeter comprises a display device 1, infrared light-emitting diodes 2, a CCD camera 3, a half mirror 4, an image processing device 5, a computer 6, and an operating switch 7. The computer 6 shows a fixed eye-target for fixing a line of sight of a subject and a light stimulus eye-target for giving a light stimulus to a pupil of the subject at a plurality of predetermined positions on the display device 1. The infrared light-emitting diodes 2 irradiate infrared light to an eye of the subject. The CCD camera 3 takes an image of the eye of the subject using the infrared light irradiated from the infrared light-emitting diodes 2. The image processing device 5 detects a pupil diameter of the subject based on the image taken by the CCD camera 3. The computer 6 measures a visual field of the subject based on the change of the pupil diameter of the subject detected by the image processing device 5. The feature of the present invention resides in that the display device 1 comprises a display device capable of adjusting background luminance of a screen and brightness of the light stimulus eye-target separately.

    摘要: An electric toothbrush with a control circuit capable of stopping the brushing operation when the brush is pressed against an user's teeth with an excessive force. The electric toothbrush comprises a housing which carries a shaft mounting a brush. The housing incorporates a rotary electric motor and a motion conversion mechanism which converts a rotational movement of the motor to a reciprocatory movement of the shaft for reciprocating said brush. A pressure sensor is provided to sense a brush pressure being applied back to the brush as a counter-action when pressing the brush against the user's teeth and to produce a stop signal when the sensed brush pressure exceeds a predetermined limit level.
