Patent number: 6100909Abstract: An apparatus for forming an image comprising a substrate with a plurality of high voltage transistors on the substrate. The transistors include a source electrode, a drain electrode and a gate electrode. Each transistor switches a marking potential of several hundred volts between the source and drain by a gate potential of at least an order of magnitude lower than the source to drain potential. There are a plurality of high voltage capacitors on the substrate. One of each capacitor is connected to one of the drain electrodes and each capacitor stores a charge potential approximately equal to the marking potential. The charge potential on each capacitor controls the forming of the image. A first data input on the substrate selectively loads a gate potential on gate the electrodes. A second data input located on the periphery of the substrate selectively loads a source potential on the source electrodes.Type: GrantFiled: March 2, 1998Date of Patent: August 8, 2000Assignee: Xerox CorporationInventors: Werner E. Haas, Joel A. Kubby

Patent number: 5708950Abstract: Printing machines which incorporate a transfusing station having a transfusing member with a resistive heater layer, a substrate, and a release layer. The transfusing station is entrained between at least two electrically conductive contact members, such as rollers, which electrically contact the heater layer. An electrical source sends current through the conductive rollers and the heater layer, heating that layer, the substrate, the release layer, and any toner on the release layer. A backup roller adjacent the transfusing member and the conductive rollers induces pressure on marking substrates which pass between the backup roller and the transfusing member. The combination of heat from the heater layer and pressure induced by the backup roller causes any toner image on the transfusing member to fuse onto the marking substrate. The release layer assists in transferring the toner onto the marking substrate.Type: GrantFiled: December 6, 1995Date of Patent: January 13, 1998Assignee: Xerox CorporationInventors: Santokh S. Badesha, Werner E. Haas, Rasin Moser, Henry R. Till, Anthony M. Wallace, William H. Wayman

Patent number: 5408299Abstract: A printing machine in which a recording medium has a latent image recorded thereon. A housing stores a supply of liquid developer material therein. The housing is operatively associated with a donor member for substantially uniformly coating liquid developer material thereon. The donor member is spaced from the recording medium. As the donor member moves, it transports the developer material to a development zone wherein the latent image recorded on the recording medium attracts at least the toner thereto to form a developed image thereon. A multicolor image may be formed by repeating this process for different developer materials.Type: GrantFiled: October 28, 1993Date of Patent: April 18, 1995Assignee: Xerox CorporationInventor: Werner E. Haas

Patent number: 5103325Abstract: A holographic display includes "segmented" images configured as if positioned in separate viewing "cells" corresponding spatially to preselected subareas of a desired display area with invisible segmenting cell sides. In one embodiment, a polarized conjugate reference light source projects the segmented hologram images form a light-transmissive recording medium into the display area, a multi-element nematic 90.degree. twisted shutter assembly changes the polarization of light emanating from subareas corresponding to the images to be blocked while keeping unchanged the polarization of the segmented images to be displayed, and a sheet polarizer positioned between the multi-element shutter and the viewer blocks from view images from those subareas which the polarization direction has been changed by the multi-element shutter. In other embodiments, light-reflective recording mediums and multi-element nematic shutters having an appropriate guest-host dyes are used.Type: GrantFiled: October 1, 1990Date of Patent: April 7, 1992Assignee: Xerox CorporationInventors: John R.

Patent number: 4920364Abstract: A variable attenuator for controlling scanning beam intensity having a twisted nematic liquid crystal for rotating the beam, a polarization analyzer for detecting the degree of alteration in the polarization of the beam by the crystal comprising a polarizing beam splitting plate separating the beam into primary and secondary beams, a photocell providing a signal reflecting the intensity of the secondary beam, a control for adjusting power to the crystal in response to the signal, a glass plate at an angle of incidence equal to but opposite from that of the beam splitting plate for correcting aberrations to the primary beam, and an anti-reflective coating on the optical surfaces of the crystal.In a second embodiment, the plates are replaced by a polarizing cube. In a third embodiment, to obviate fluctuations in the attenuator output, the glass plate instead serves as the source of the beam component to the photocell.Type: GrantFiled: May 10, 1989Date of Patent: April 24, 1990Assignee: Xerox CorporationInventors: John R.

Patent number: 4786858Abstract: A voltage sensing device having a liquid crystal cell electrically connected to a charged surface and having a light transmissivity varying with applied voltage. A light source is directed through the liquid crystal cell, and a light detector, detects changes in the intensity of light directed through the cell and providing an output indicative of variations in voltage on the charged surface. Polarizers, which polarize light from the light source directed through the liquid crystal cell, and analyze light exiting the cell, convert electro-optically induced phase changes into intensity changes. A saturation level biasing voltage is periodically applied to the liquid crystal cell to set the cell to a reference level, clearing the cell of transient polarization effects. A second reference liquid crystal cell may be provided, electrically coupled to a reference voltage.Type: GrantFiled: December 18, 1986Date of Patent: November 22, 1988Assignee: Xerox CorporationInventors: Werner E. Haas, John R. Andrews

Patent number: 4752806Abstract: A multi-mode imaging system provides the capability of reproducing documents in a conventional COPY mode wherein a document is placed on a platen and scanned to create an exposed latent image on a photosensitive member. The system is adapted to operate in a second, print (WRITE) mode wherein an image bar, such as a light-emitting diode (LED) array or a liquid crystal shutter (LCS), is placed into optical alignment with a fixed optical system including a linear lens array. The image bar is electrically addressed to create a light output in an image-wise pattern (LCD) or to change the state of the LCS. The image output is optically coupled into the lens array which projects the image onto the photosensitive member. In one embodiment, the image bar is partially within the end portion of a movable plate.Type: GrantFiled: June 23, 1986Date of Patent: June 21, 1988Assignee: Xerox CorporationInventors: Werner E.

Patent number: 3951519Abstract: An imaging system wherein an imaging member comprises a layer of a homeotropically aligned nematic liquid crystalline material which is optically uniaxial residing on a photoconductive insulating layer. When the liquid crystal layer is subjected to an electrostatic charge and the photoconductive insulating layer is exposed to an imagewise pattern of activating electromagnetic radiation, the liquid crystalline material is subjected in selective areas to an electrical field which has components both in the plane of the layer and normal to the plane of the layer thereby inducing optical biaxiality in those areas of the imaging material. In a preferred embodiment of the invention a layer of a suitable overcoating material is arranged over the liquid crystal layer.Type: GrantFiled: August 19, 1974Date of Patent: April 20, 1976Assignee: Xerox CorporationInventors: Fred W. Schmidlin, Werner E. Haas, James E. Adams
