    • The test apparatus is composed of a clock signal generating circuit, a patterned pulse generating circuit operated in synchronism with the clock signal generating circuit, with the output of the patterned pulse generating circuit being furnished to an integrated circuit to be tested, a reference voltage generating circuit, a comparator circuit to compare the output pulses from the integrated circuit to be tested with the output from the reference voltage generating circuit, a function pulse generating circuit synchronized with an output from the comparator circuit, a circuit for detecting coincidence between the output from the comparator circuit and the output from the function pulse generating circuit, and a displaying circuit to display the output of the coincidence detecting circuit, whereby the validity of the integrated circuit is determined from the coincidence of the output pulses from the integrated circuit with the expected pulse patterns obtained from the function pulse generating circuit.

    • A photoelectric transducer comprising at least a light-transmissive substrate having a relatively flat surface provided on its light-receiving side and an uneven surface provided on its opposite side, and a photoelectric transducing layer provided on the uneven surface of the substrate. The photoelectric transducing layer comprises at least a light-transmissive conductive layer, a semiconductor layer, and a back conductive electrode layer. The back conductive electrode layer comprises a second light-transmissive conductive layer and a conductive layer. The uneven surface on the substrate includes numerous projections, each projection having a triangular section and a shape of pyramidal, ridged roof, or conical type. The projections and the second light-transmissive conductive layer of the uneven back conductive electrode layer elongate the optical path of light beams in the photoelectric transducing layer, and prevent the adherence of dust particles and the abrasion of the photoelectric transducing layer.
