Abstract:
     The main feature is to effect variation of photosensitive resistance by regulating the light shield for the photocell, thus obtd. the same result of conventional adjustable resistor. It can be used under vibration conditions and the illumination of the luminous element can be adjusted to change the resistance range of the photocell for better adjusting precision of each resistance section. It can be applied to industrial automation and electric appliances for family use.
