Disclosed is a method for producing an electro-photographic photoreceptor capable of repeated copying without one imagewise exposure for every one copying and which is superior in stability, sensitivity, resolution and tone reproduction. This method comprises converting to an insulator, by irradiation with energy ray, any selected area of a surface of an electrophotographic photoreceptor comprising a conductive substrate, a carrier generation layer and a carrier transport layer composed mainly of a compound which is converted to an insulator by irradiation with energy ray.

Disclosed is a method and apparatus for feeding a material to a hot forging machine in a forging line in which a coiled material is uncoiled, straightened, fed intermittently by pinch rollers through a heating device, cut by a cutting device and then fed into a hot forging machine. The method has the steps of preparing a driving device which drives the pinch rollers mechanically independently from the hot forging machine; picking up the timing of forging conducted by the hot forging machine as an electric signal, and controlling the driving device in accordance with the electric signal.

摘要:
A NTCDA single crystal is used as a photoelectric current multiplier layer, and Au thin films are formed as electrodes on the opposite surfaces of the multiplier layer by a vapor deposition method to form a sandwich type cell. When a voltage is applied to the NTCDA single crystal by the electrodes from a dc power source and a monochromatic light is applied, a multiplied photoelectric current flows between the electrodes. A rise of this element at light-on is considerably faster than when a vapor-deposited layer is used as a photoelectric current multiplier layer to permit a faster response.
