  • Patent number: 8287995
    Abstract: The invention seeks to increase the sealing property and the reliability of an electronic device by suppressing cracks, fractures and the like of a glass substrate at the time of laser sealing. A glass substrate 3 has a sealing region. On the sealing region, a sealing material layer 5 comprising a glass material for sealing containing a low-expansion filler and a laser absorbent is provided. The glass material for sealing contains no low-expansion filler particles having particle sizes exceeding the thickness T of the sealing material layer 5 and contains low-expansion filler particles having particle sizes within a range of from 0.5T to 1T based on the thickness T of the sealing material layer 5 in a volume ratio of from 0.1 to 50%. Such a glass substrate 3 and a glass substrate 2 having an element-formed region provided with an electronic element are laminated, and the sealing material layer 5 is irradiated with a laser light 6 and melted to bond the glass substrates 2 and 3.

  • Publication number: 20110209813
    Abstract: Laser sealing property and reliability of a glass panel are increased by suppressing cracks, fractures, separation and the like of glass substrates and a sealing material layer at the time of laser sealing. A first paste for a sealing material containing no laser absorbent and a second paste for a sealing material containing a laser absorbent are applied in this order on a sealing region 2a of a glass substrate 2. A laminate film of a coating layer 11 of the first paste for a sealing material and a coating layer 12 of the second paste for a sealing material is fired, to form a sealing material layer 3 having a laminated structure of a layer 4 of the first glass material for sealing and a layer 5 of the second glass material for sealing.

  • Patent number: 4841267
    Abstract: A deflection apparatus for cathode ray tube is provided, which comprises deflection yoke with guide grooves, deflection windings for scanning in one direction in said grooves, deflection windings for scanning in the other direction and an insulator between both types of windings. It attains high accuracy deflection with less distortion without any induced heating problem due to protuberances made relatively between grooves.

  • Patent number: 4208318
    Abstract: A thermoplastic resin is colored with a carbon black pigment in the presence of a sulfonamide-substituted metal phthalocyanine dyestuff of the general formula ##STR1## wherein MePc is a metal phthalocyanine residue, R.sub.1 is a hydrogen atom or an alkyl group, R.sub.2 is an alkyl group, R.sub.3 is a hydrogen atom or an alkoxyalkyl group, R.sub.4 is an alkoxyalkyl group, m is an integer of 0 to 4, n is an integer of 0 to 4, and m+n is an integer of 1 to 4. The use of the specified metal phthalocyanine dyestuff affords a completely black or bluish black thermoplastic resin free from a reddish hue which is inherent to coloration with carbon black.
