Patent number: 6900851Abstract: The invention features a photoconductively addressed display and a method of photoconductive addressing in a display. The method includes providing an electro-optic imaging layer that extends in an X direction and a Y direction and comprises an array of image elements. A column electrode layer is provided adjacent to one side of the electro-optic imaging layer. The column electrode layer includes a plurality of column electrodes that each extend in the Y direction and are spaced from one another in the X direction. A photoconductive layer disposed between the electro-optic imaging layer and the column electrode layer is provided. An elongate portion of the photoconductive layer is illuminated in the X direction while scanning the illumination in the Y direction to translate a location of the illuminated elongate portion.Type: GrantFiled: February 8, 2002Date of Patent: May 31, 2005Assignee: E Ink CorporationInventors: Ian D. Morrison, Rachael A. Forgit, Peter J. Valianatos, Craig A. Herb, Guy M. Danner

Patent number: 5942360Abstract: A photoreceptor includes a supporting substrate and an outer layer on the photoreceptor, the outer layer including silicone oil uniformly dispersed as vesicles in a continuous film forming polymer matrix. This photoreceptor is used in a xerographic copier/printer machine and contributes to a longer operating life of the machine by providing continuous lubrication, decreased friction and decreased wear of the interaction of the photoreceptor and other machine parts. This photoreceptor is prepared by incorporating silicone oil and at least one film forming polymer in at least one solvent, removing the solvent and forming a dried outer layer in which the silicone oil is phase separated from the other components of the top layer forming small vesicles which are uniformly dispersed in the continuous film forming polymer matrix.Type: GrantFiled: March 31, 1998Date of Patent: August 24, 1999Assignee: Xerox CorporationInventors: Roger T. Janezic, William W. Limburg, Mark Petropoulos, Rachael A. Forgit, Mark S. Thomas, Russell N. Gillmeister

Patent number: 5820897Abstract: This invention discloses a method of holding and transporting a hollow flexible belt throughout a coating process. The method includes placing an expandable insert into the hollow portion of a seamless flexible belt, and expanding the insert until it forms a chucking device with a protrusion on at least one end. A mechanical handling device is then attached to the protrusion, and will be used to move the chuck and the belt through the dipping process, as materials needed to produce a photosensitive device are deposited onto the surface of the belt, allowing it to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, the belt is cut to the desired width, and the chuck is removed from the inside of the photoreceptor.Type: GrantFiled: July 27, 1995Date of Patent: October 13, 1998Assignee: Xerox CorporationInventors: John S. Chambers, Eugene A. Swain, Ronald E. Godlove, Rachael A. Forgit, Huoy-Jen Yuh

Patent number: 5788774Abstract: There is disclosed an assembly for selectively coating a hollow, cylindrical first substrate defining a first open end region having an outer surface and an inner surface and a second open end region, the assembly including a first plug member fabricated from a nonwetting material, wherein the plug member has a bottom surface defining a pallet coupling feature and a top surface defining a cavity region encompassed by a circumferentially extending rigid side wall having an outer surface and an inner surface, wherein the first end region of the substrate is disposed in the cavity region where the inner surface of the side wall grips the outer surface of the first end region of the substrate to couple the first plug member to the first end region, whereby the plug member minimizes coating of the outer surface and the inner surface of the first end region of the substrate by a coating solution.Type: GrantFiled: January 21, 1997Date of Patent: August 4, 1998Assignee: Xerox CorporationInventors: Robert E. Mccumiskey, John S. Chambers, Rachael A. Forgit
