  • Patent number: 6840833
    Abstract: In the manufacture of a gas discharge type display panel, by applying a sealing operation along with an exhausting operation, the sealing glass 14 is broken down by a pressure difference between the inside and outside of the panel, and thus, the clearance gap between the substrates can be controlled as desired. In addition, the gaseous component that is unnecessary for the discharge operation is exhausted by setting the temperature of the amorphous sealing glass to exceed its softening-point and be no more than its working point. In the structure of the gas discharge type display panel, a protruding portion having a radius of curvature between 0.1 mm and 1 mm is formed on the sealing glass to reduce the dispersion in the thickness direction of the sealing glass, or the cross-sectional shape of the sealing glass is made convex both at its inside end part and its outside end part.

  • Publication number: 20040031049
    Abstract: Multi-camera signal distribution conducted by a plurality of broadcasters has various problems of charging, video switching and copyright from the user's viewpoint. In order to solve these problems, first, a charging unit is provided for charging at a measured-rate charging to the assessment price of contents. Secondly, a program scramble is used to encrypt the whole service and a show scramble to encrypt each show, or each channel, thus making it possible to offer service according to the conditions of a contract the viewer made. Third, a show selection unit is provided to select shows on a show selection guide picture displayed on the screen of a communication terminal that has a remote control function. Use of this charging system could prevent the total amount of charging from increasing even if channels to view are frequently changed.

  • Patent number: 5610570
    Abstract: A non-linear resistor having a high impulse withstanding ability is obtained by directly applying a crystallized glass to the side surface of a sintered body of a ZnO element, and then bake-attaching the crystallized glass to the side surface of the ZnO element by heat treatment. Since the impulse withstanding ability is improved by applying the crystallized glass as the side surface high-resistivity layer of the voltage non-linear resistor, the performance and reliability of an arrester including the resistor is improved.
