  • Patent number: 7635950
    Abstract: A short-arc type high pressure discharge lamp in which durability is improved and a lamp apparatus including the same is provided. Glass material portions 52A into which glass material enters respectively are provided on both sides of an electrode axis 5402 between the outer circumferential surface 5406 thereof and a curved portion 58 of a sealed metal foil 56, and a gap S3 being continuous with a sealed space 60 remains among the glass material portion 52A, the outer circumferential portion 5406 of the electrode axis 5402, and the curved portion 58. An angle formed by a surface 52-1 of the glass material portion 52A facing the gap S3 and the curved portion 58 is an obtuse angle ?. In other words, an angle formed by the surface 52-1 of the glass material portion 52A facing the gap S3 and a surface 5602 of the curved portion 58 of the sealed metal foil 56 is the obtuse angle ?.

  • Patent number: 5277640
    Abstract: A mount for supporting a cathode-ray tube is employed in a frit sealing furnace. The frit seal furnace (1) comprises a furnace body (3) and conveyor belts (5) disposed in the furnace body (3) for feeding mounts (21) which each support a panel (31) and a funnel (32) that are superposed one on the other with a frit glass (33) interposed therebetween. Each of the conveyor belts (5) is composed of a pair of chain belts (4a, 4b). The mount (21) is placed on the conveyor belts (5) in the frit seal furnace (1) through a space which comprises a mesh screen (26), so that the mount (21) is suitable for use in the frit seal furnace (1). When the tube body of a cathode-ray tube is broken, glass pieces are prevented from falling onto the furnace floor by the mesh screen. The mesh screen does not obstruct air flows in the furnace.

  • Patent number: 5167555
    Abstract: A method and an apparatus for manufacture of a cathode-ray tube where an electron gun for emitting a plurality of electron beams is enclosed in a tube body with discrete electrodes disposed individually to such beams and joint electrodes disposed commonly to the beams. The method comprises the steps of incorporating the electron gun in the tube body and applying high-frequency induction heat principally to the joint electrodes to thereby evacuate and seal up the tube body; flashing a getter material; and disposing at least a pair of cored coils on both sides of the tube body at positions opposite to the discrete electrodes disposed individually to the plurality of beams, and applying high-frequency induction heat principally to the discrete electrodes.
