  • Patent number: 7645401
    Abstract: Disclosed is a modified electroconductive polymer material, which comprises a metal filled in a space between the chains of an electroconductive polymer. The metal is oxidized (partially formed as a hydroxide) through a chemical reaction between three substances consisting of the metal, a cation radical/dication, and absorbed water. The metal has a work function less than that of the electroconductive polymer. The contact between the metal and the electroconductive polymer is kept in the state of coexistence between three substances consisting of the metal, the cation radical/dication and the absorbed water. This allows an electroconductive polymer material to have enhanced durability against oxidation/reduction, and controlled conductivity.

  • Patent number: 7357884
    Abstract: A conductive ink composition is obtained by dispersing, in an organic solvent, a solid material made from metal fine particles each coated with protective colloids each made of at least two organic compounds, the metal fine particles consisting of an alloy containing at least a noble metal. Each of the protective colloids is made from, e.g., a raw material containing an (A) amine and a (B) carboxylic acid. By applying and baking the conductive ink composition, grain growth is restrained. This allows acquirement of a metal film whose surface smoothness is excellent, and whose adhesiveness to an application target is improved as compared with that of a metal film made from a conventional conductive ink composition.

  • Publication number: 20080035896
    Abstract: The glass ceramic plate for a cooking apparatus is transparent to visible light and IR radiation and has a noble metal film on its underside. The noble metal film is composed of an alloy of gold, platinum and/or palladium, which imparts a reflective property to it. It contains from 0 to 5 percent by weight, in relation to a total metal content, of silver, copper, silicon, bismuth and other metals that are not noble metals. The glass ceramic plate coated with the noble metal film has a spectral transmission of 0 to 12% in the infrared region of the spectrum. When a decoration consisting of a grid of unsymmetrically distributed elements is provided on the topside of the glass ceramic plate, defects in the glass ceramic material can be concealed. The invention also includes a method of coating.

  • Patent number: 7049009
    Abstract: A method of sputter depositing silver selenide and controlling the stoichiometry and nodular defect formations of a sputter deposited silver-selenide film. The method includes depositing silver-selenide using a sputter deposition process at a pressure of about 0.3 mTorr to about 10 mTorr. In accordance with one aspect of the invention, an RF sputter deposition process may be used preferably at pressures of about 2 mTorr to about 3 mTorr. In accordance with another aspect of the invention, a pulse DC sputter deposition process may be used preferably at pressures of about 4 mTorr to about 5 mTorr.

  • Patent number: 6855196
    Abstract: An ink for a display panel effective in reducing the uneven adhesion of the ink is applied by an ink application apparatus using an inkjet method to form a structural layer (e.g. reflective layer, phosphor layer) of a display panel such as a plasma display panel. The ink is delivered through a nozzle of the ink application apparatus and includes a powder material used in forming the structural layer, water or a water-miscible solvent, a binder formed from a water-soluble resin, and a plasticizer. The flexibility retained by the ink, even after the ink is applied, allows for leveling of the applied ink to occur and uneven adhesion to be reduced as a result.
