  • Patent number: 5270612
    Abstract: A faceplate for a tension mask CRT has a plurality of metallic inlays embedded in the glass of an inner surface of the faceplate. The inlays have a surface substantially coplanar with the faceplate inner surface for receiving and securing thereto a tension mask frame.

  • Patent number: 4880665
    Abstract: A system for recognizing touch positions along a predetermined coordinate axis on a surface of a touch panel display apparatus comprises a substrate having a surface capable of propagating surface acoustic waves and is so characterized that a touch on that surface causes amplitude damping of a surface wave passing through the region of touch. An input surface wave transducer, coupled to the substrate surface launches a burst of surface waves on the surface in a first direction parallel to the aforesaid axis. An output surface wave transducer is also coupled to the substrate. A first surface wave reflecting means derives wave components from the launched wave and reflects them across the display surface to a second wave reflecting means that redirects the reflected components in a second direction opposite to the aforesaid first direction.

  • Patent number: 4859996
    Abstract: A system for recognizing touch positions along a predetermined coordinate axis includes a surface wave propagating substrate on which is disposed at least one surface wave transducer. An array of surface wave reflective elements directs the surface wave from the transducer. The reflective elements are composed of a frit material.

  • Patent number: 4280931
    Abstract: An improved electrically resistive arc-suppressive material is disclosed for use in a television cathode ray tube. The tube includes a funnel with a conductive coating on the inner surface thereof and a neck enclosing an electron gun having snubber springs extending from an anode electrode. The arc-suppressive material according to the invention is deposited in an area between the conductive coating and the gun and in contact with the snubber springs. The improved resistive material comprises tin oxide (SnO.sub.2) doped with an antimony compound and calcined in a semi-sealed crucible for about two hours at a temperature in the range of 1306.degree. C. to 1326.degree. C., and blended with glass frit in a weight-percent ratio range of 45-55. The doping and the temperature range and duration are effective to inbue the material with a hardness resistant to plowing by the snubber springs, and electrical resistance value effective to suppress arcing.

  • Patent number: 4153857
    Abstract: The disclosure depicts in a television cathode ray tube having a getter containing a vaporizable, electrically conductive, gas adsorptive getter material, an improvement comprising an electrically resistive element for arc suppression, an electrically resistive element for arc suppression, internal voltage division, static elimination, RC signal coupling or the like. The resistive element is composed of a high resistivity material compatible with a clean, high-vacuum environment. The element is so widely and deeply cavitated and contorted at and below its nominal surface that the real surface of the element is shadowed and very greatly extended in area relative to the nominal surface of the element. The effect of this is that when the getter is flashed, the coating of conductive getter material deposited on the element is effectively dispersed and fragmented into isolated conductive islands.
