Patent number: 6677700Abstract: A color cathode-ray tube has an evacuated envelope with an electron gun therein for generating an electron beam. The envelope further includes a faceplate panel having a luminescent screen with phosphor elements on an interior surface thereof. A focus mask, having a plurality of spaced-apart first conductive strands, is located adjacent to an effective picture area of the screen. The spacing between the first conductive strands defines a plurality of apertures substantially parallel to the phosphor elements on the screen. Each of the first conductive strands has a substantially continuous insulating material layer formed on a screen-facing side thereof. A plurality of second conductive wires are oriented substantially perpendicular to the plurality of first conductive strands and are bonded thereto by the insulating material layer. The insulating material layer is partially or slightly conductive to an extent sufficient to prevent an accumulation of a significant electrical charge.Type: GrantFiled: December 22, 2000Date of Patent: January 13, 2004Assignee: Thomson Licensing S. A.Inventors: Samuel Paul Benigni, Wilber Clarence Stewart, Philip Michael Heyman, Richard William Nosker

Patent number: 6541901Abstract: A tension mask frame assembly for a color cathode-ray-tube including a frame having four respective sides, two of the sides paralleling each other and having insert receiving brackets for supporting strand termination inserts therein and vertical mask strands welded to said termination inserts. The strands have a plurality of cross-wires extending perpendicular to the strands and attached thereto by a conductive bonding material. The wires and termination inserts are composed of materials having a first coefficient of thermal expansion. The frame and receiving brackets are composed of materials having a second coefficient of thermal expansion. The termination inserts thermally expand and contract independently of the frame and receiving brackets, whereby movement of the strands in the horizontal dimension is controlled by thermal expansion and contraction of the termination inserts and cross-wires.Type: GrantFiled: February 26, 2001Date of Patent: April 1, 2003Assignee: Thomson Licensing S.A.Inventors: Istvan Gorog, Joey John Michalchuk, Richard William Nosker, Philip Michael Heyman

Patent number: 6246164Abstract: A color picture tube has a tensioned mask supported by a support frame mounted within said tube. The mask has a significantly lower coeffiecient of thermal expansion than the frame. Intermediary members are located between the mask and the frame. The intermediary members are of a material similar to that of the mask. Each of the members is attached to the frame at a single location and the mask is attached to edges of the intermediary members. Further included are guides for holding the intermediary members to the frame while permitting expansion of the frame relative to the intermediary members.Type: GrantFiled: April 1, 1999Date of Patent: June 12, 2001Assignee: Thomson Licensing S.A.Inventors: Philip Michael Heyman, Richard William Nosker, Joey John Michalchuk, Istvan Gorog

Patent number: 3981560Abstract: An electrochromic display device includes an electrolyte and at least one transparent electrically conductive electrode. An organic insulating layer e.g. a photoresist material, is disposed between the transparent electrode and the electrolyte such that no portion of the transparent electrode is in contact with the electrolyte. The insulating layer protects the transparent electrode from deterioration so as to increase the lifetime of the transparent electrode.Type: GrantFiled: June 16, 1975Date of Patent: September 21, 1976Assignee: RCA CorporationInventors: Philip Michael Heyman, Robert Leon Quinn, Istvan Gorog
