  • Method of manufacturing an image display apparatus by supplying current to seal the image display apparatus
    Patent number: 7247072
    Abstract: An image display apparatus includes an envelope which has a front substrate and a rear substrate opposed to each other and individually having peripheral edge portions sealed together. A sealed portion is sealed by a sealing member. the sealing member has electrical conductivity and melts when supplied with current. After the sealing member in the sealed portion is supplied with current and melted during manufacture, the current supply is stopped to cool and solidify the sealing member, whereupon the respective peripheral edge portions of the front substrate and the rear substrate are selected together.
    Type: Grant
    Filed: October 23, 2003
    Date of Patent: July 24, 2007
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Masahiro Yokota, Takashi Enomoto, Takashi Nishimura, Akiyoshi Yamada, Shouichi Yokoyama

  • Process for producing an oxide superconductor from alkoxides
    Patent number: 5304533
    Abstract: A process for producing a superconductor of an oxide system, which comprises uniformly mixing metal elements for constituting the oxide system at least partly in the form of alkoxides having CN.sup.--, X.sup.-- wherein A is a halogen atom and/or an amine, with the rest, if any, being in the form of acetylacetonates, carboxylates and/or water-soluble inorganic compounds to obtain a homogeneous mixture, and sintering the mixture.

  • Process for producing a superconductor of an oxide system from acetylacetonates
    Patent number: 5004720
    Abstract: A process for producing a superconductor of an oxide system, which comprises uniformly mixing metal elements for constituting the oxide system at least partly in the form of acetylacetonates in a solvent with the rest, if any, being in the form of alkoxides, carboxylates and/or inorganic salts, hydroxides and/or oxides to obtain a homogeneous mixture, and sintering the mixture.
