  • Patent number: 7417365
    Abstract: In a corner portion outside a display region of a face substrate which constitutes a face panel of a display device, an opening is formed. In the opening, a stem glass structural body which is configured by integrally forming an exhaust pipe on a center portion of a stem glass and by forming conductive leads in a peripheral portion thereof in an embedded manner, is fixed by welding using curing by heating. The exhaust pipe is evacuated and, thereafter, tipped off, thus realizing vacuum sealing of the inside thereof. A lead line is connected to a distal end of one conductive lead by welding and another end of the lead line is electrically connected with one end portion of the anode formed on an inner surface of the face substrate using a conductive adhesive agent. Further, a getter is mounted and fixed to another conductive lead line by welding.

  • Patent number: 7323813
    Abstract: Assuming an aperture diameter of an electron beam aperture formed in a shield cup as Vsc, an aperture diameter of an electron beam aperture formed in an inner electrode of a focusing electrode as V5, and a distance between the electron beam aperture formed in the shield cup and the inner electrode as L, the above-mentioned aperture diameter Vsc, the aperture diameter V5 and the distance L are determined to satisfy tan ?=(V5?Vsc)/2L?0.08. Due to such a constitution, it is possible to enhance the degree of vacuum in the inside of a cathode ray tube and, it is possible to prevent a getter for elevating the degree of vacuum in the inside of the cathode ray tube and for maintaining the elevated degree of the vacuum from being scattered to the electron gun side thus preventing the deterioration of the characteristics of the electron gun.

  • Publication number: 20060158085
    Abstract: In an image display apparatus having scanning lines and data lines mutually intersecting through an insulating layer and a cathode substrate formed with electron-emission areas, whereby electrons accelerated from the electron-emission areas impinge on fluorescent materials provided on an anode substrate to make them luminesce, an intermediate layer is provided at a portion where a scanning line overlaps a data line and the surface of the intermediate layer opposing a spacer is less uneven and flattened. The intermediate layer is, for example, an interlayer insulating film formed on the data line or a thick-film electrode layer formed between the scanning line and the spacer. Alternatively, the cathode substrate is formed with recesses in which the data lines are fitted so as to flatten an intersectional portion of the scanning line and the data line.

  • Publication number: 20030214217
    Abstract: Out of focusing electrodes which face each other in an opposed manner and constitute an electrostatic quadruple lens, one focusing electrode includes planar correction electrode plates which extend parallel to a tube axis while sandwiching electron beams from above and below. Here, the correction electrode plates include a reinforcing mechanism for suppressing the deformation or the displacement of the planar correction electrode plates. By suppressing the deformation and the displacement of the planar correction electrode plates which form the electrostatic quadruple lens, it is possible to provide a color cathode ray tube capable of exhibiting excellent focusing characteristics over an entire screen.

  • Patent number: 5564102
    Abstract: An object material to be melted (radioactive liquid waste and glass material) 16 is charged into the interior of a cold-crucible induction melting apparatus 10, and a conductor 18 the melting point of which is higher than that of the glass material is inserted into a melting furnace 12. A high-frequency current is supplied to a coil 14 so as to generate heat in the conductor and indirectly heat the glass material. The conductor is withdrawn after a part of the glass material has been put in a molten state. The glass material as a whole is thereafter kept in a molten state while maintaining the induction heating by the molten glass material. The conductor inserted into the melting furnace is, for example, a silicon carbide rod. The surface of the molten material which contacts the inner surface of the melting furnace turns into a solid layer (skull) due to cooling, so that the molten material does not directly contact the refractories.
