  • Electron gun for cathode-ray tube with improved beam shaping region
    Patent number: 7486009
    Abstract: An electrode gun for a cathode-ray tube, including at least a first electrode and a second electrode for shaping and focusing the electron beam emitted by a cathode is described. These electrodes are made of a non-oxidizing alloy whose coefficient of expansion between 20° C. and 300° C. lies between 4×10?6/° C. and 13×10?6/° C.
    Type: Grant
    Filed: March 18, 2005
    Date of Patent: February 3, 2009
    Assignee: Thomson Licensing

  • Low consumption cathode structure for cathode ray tubes
    Patent number: 7439664
    Abstract: Cathode structure for cathode ray tube comprising an eyelet in two separate parts positioned such that one of the parts covers, in the longitudinal direction and at least partially, the second part. The two parts are linked to each other at the shouldered ends. This structure reduces the heat losses of the cathode and reduces its consumption while it is operating.

  • Electron gun structure for a cathode-ray tube
    Patent number: 7042146
    Abstract: The disclosure describes an electron gun having cathode support structure which comprises an eyelet that surrounds a cathode and is welded to the cathode, and a metal plate 150 substantially parallel to the longitudinal axis of the gun. The metal plate has a central part 152 folded so as to partially surround the eyelet and two side arms 151 extending an each side of the central part and connected thereto by a region 155. The region has, in the direction of the longitudinal axis, a width which is greater than the width of the side arms in the same direction, thereby making it possible to use the same support for the side and central cathodes of a three-beam gun.
