Abstract

PURPOSE: To obtain a contactless, high prescision and high resolution resistor in which belt-shaped photo conductive films are provided among three lines of parallel electroees and incident light is controlled by an opaque material sliding on the film in the longitudinal direction, and output is taken up from an intermediate electrode.
