  • Multilayered photoreceptor with adhesive and intermediate layers
    Patent number: 5591554
    Abstract: An electrophotographic imaging member is disclosed including a support substrate having a two layered electrically conductive ground plane layer comprising a layer comprising zirconium over a layer comprising titanium a hole blocking layer, an adhesive layer comprising a copolyester film forming resin, an intermediate layer over and in contact with the adhesive layer, the intermediate layer comprising a carbazole polymer, a charge generation layer comprising a perylene or a phthalocyanine, and a hole transport layer, said hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from said charge generation layer and transporting said holes through said charge transport layer.
    Type: Grant

  • Electrophotographic imaging member containing zirconium in base layer
    Patent number: 4780385
    Abstract: An electrophotographic imaging member is disclosed having an imaging surface adapted to accept a negative electrical charge, the electrophotographic imaging member comprising a metal ground plane layer comprising zirconium, a hole blocking layer, a charge generation layer comprising photoconductive particles dispersed in a film forming resin binder, and a hole transport layer, the hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from the charge generation layer and transporting the holes through the charge transport layer.
    Type: Grant
    Filed: April 21, 1987
    Date of Patent: October 25, 1988
    Assignee: Xerox Corporation
    Inventors: Francis J. Wieloch, Charles C. Robinson, Frederick D. Gonyea, Harvey S. Towers, Anthony M. Horgan, Edward F. Grabowski, Satish Parikh
  • Mold for casting contact lenses utilizing and electron beam to polymerize the resin lens
    Patent number: 4017238
    Abstract: A mold for casting contact lenses from an unpolymerized resin such as silicone gum wherein the resin is polymerized by high energy radiation such as an electron beam. One part of the mold is a cap capable of transmitting such radiation. The male section of the mold is gold plated to minimize reaction between the resin and the male section under the influence of the electron beam.
