Patent number: 6899916Abstract: A composite substrate includes a substrate, an electrode formed on the substrate, a first dielectric layer of thick film dielectric formed on the electrode, a second dielectric layer formed on the first dielectric layer by a solution coating-and-firing technique, and a buffer layer formed below and/or within the first dielectric layer. The composite substrate keeps the thick-film dielectric layer fully insulating and enables functional thin films formed thereon such as a light emitting layer to perform stable operation, especially stable light emission. An EL panel using the same and a method for preparing the same are also provided.Type: GrantFiled: October 29, 2002Date of Patent: May 31, 2005Assignee: The Westaim CorporationInventors: Yoshio Saita, Jun Hagiwara, Yukihiko Shirakawa, Masato Susukida

Patent number: 6614460Abstract: A thermal head including a protection layer having mutually opposed first and second surfaces, said first surface having a flat or protruded printing surface which is brought into contact with a heat sensitive record medium, a heat generating section including resistors and electrodes connected to the electrodes and provided on said second surface of the protection layer, and a reinforcing member made of a low melting pint glass and provided on a side of the heat generating section remote from the protection layer. The reinforcing member improves a mechanical strength of the thermal head. The reinforcing member made of a glass also serves as a heat storage member, and thus a thermal property of the thermal head is improved. The reinforcing member may be formed by an aggregate of ceramic particles. The reinforcing member may contain a heat storage layer made of a low melting point glass and a heat conduction layer provided on the heat storage layer.Type: GrantFiled: November 26, 2001Date of Patent: September 2, 2003Assignee: TDK CorporationInventors: Masato Susukida, Katsuto Nagano, Yoshio Saita, Jun Hirabayashi, Jun Hagiwara

Patent number: 6407764Abstract: An wear-resistant layer 50 constituting a printing surface which is brought into contact with a thermal record medium is formed on a provisional substrate 70 having a groove formed in its surface, said groove having a substantially semicircular cross section, and a heat generating layer 51, electrically conductive layers 52a and 52b electrically connected to the heat generating layer, a protection layer 54a and a heat storage layer 58 are stacked in turn to form a printing section. Next, a driving IC 55 for controlling a heating electric power to be supplied to the printing section is connected to the electrically conductive layer and a wiring section 53 for connecting the driving IC to an external circuit is provided. Thereafter, the printing section is secured to a heat dissipating member 59 by means of a resin 62, and a common electrode 84 and wires 56 are secured to the heat dissipating member by means of both-sided adhesive tapes 82 and 83.Type: GrantFiled: August 18, 1998Date of Patent: June 18, 2002Assignee: TDK CorporationInventors: Masato Susukida, Katsuto Nagano, Atsushi Yoshida, Jun Hirabayashi, Yoshio Saita, Jun Hagiwara

Publication number: 20020030728Abstract: A thermal head including a protection layer having mutually opposed first and second surfaces, said first surface having a flat or protruded printing surface which is brought into contact with a heat sensitive record medium, a heat generating section including resistors and electrodes connected to the electrodes and provided on said second surface of the protection layer, and a reinforcing member made of a low melting pint glass and provided on a side of the heat generating section remote from the protection layer. The reinforcing member improves a mechanical strength of the thermal head. The reinforcing member made of a glass also serves as a heat storage member, and thus a thermal property of the thermal head is improved. The reinforcing member may be formed by an aggregate of ceramic particles. The reinforcing member may contain a heat storage layer made of a low melting point glass and a heat conduction layer provided on the heat storage layer.Type: ApplicationFiled: November 26, 2001Publication date: March 14, 2002Applicant: TDK CorporationInventors: Masato Susukida, Katsuto Nagano, Yoshio Saita, Jun Hirabayashi, Jun Hagiwara

Patent number: 5078909Abstract: A moisture-absorbent composition contains 100 parts by weight of thermoplastic resin and 5 to 400 parts by weight of at least one among the group consisting of magnesium sulfate (represented generally by MgSO.sub.4.NH.sub.2 O (O.ltoreq.n.ltoreq.3), aluminum oxide, calcium oxide, silicon oxide, zeolite, barium oxide, and cobalt chloride. A moisture-absorbent molded item is formed of this composition in a shape of a film, a sheet, a plate, a bag, a pellet, or a container. The molded item may be used as a cushion insert, etc. which requires moisture absorption properties. A moisture-absorbent composition and an molded item made of the composition are provided with an indicator function, by specifying the amount of anhydrous cobalt chloride.Type: GrantFiled: May 22, 1990Date of Patent: January 7, 1992Assignees: Sasaki Chemicals Co., Ltd., Tomita PharmaceuticalInventors: Katsumi Shigeta, Hisao Mukai, Eiji Isojima, Yoshio Saita
