  • Patent number: 6841009
    Abstract: Disclosed is a reaction vessel used for oxidizing and decomposing equipment suitable for processing with supercritical water, and methods of manufacturing the reaction vessel. The reaction vessel comprises an oxide film containing a platinum group metal oxide for example having a fine crystalline structure, and a high corrosion resistance in both oxidizing and reducing atmosphere. The film is formed on a surface of the vessel by performing a pyrolysis reaction in an atmosphere containing water vapor. The oxide film is comprised of at least one platinum group metal oxide selected from Ir, Ru or Rh oxide, and at least one oxide of a metal selected from Ti and Ta.

  • Patent number: 6723281
    Abstract: The present invention relates to a metal material for electronic parts, electronic parts, electronic apparatuses, a method of processing metal materials, and electro-optical parts. For example, the present invention is applied to liquid crystal display panels, various semiconductor devices, wiring boards, chip parts, and the like. The present invention proposes a metal material for electronic parts which is characterized by lower resistivity, higher stability, and more excellent processability than the prior art. The present invention also proposes electronic parts and electronic apparatuses which use this metal material. An applicable metal material is an alloy containing Ag as a main component, 0.1 to 3 wt % of Pd, and 0.1 to 3 wt % in total of elements such as Al.

  • Patent number: 6228457
    Abstract: There is disclosed an optical data storage medium in which the weather resistance of the semitransparent reflective film is improved and the adhesive property between the semitransparent reflective film and a substrate is enhanced, and which has a higher reliability. In an optical data storage medium (6), on the side on which a reproduction light (8) is incident, a first information layer (9) is located while on the side opposite to the side on which the reproduction light (8) is incident, a second information layer (10) is located. A semitransparent reflective film (3) of first information layer (9) is AgPdCu alloy thin films containing 0.5 to 3.0 weight % Pd and 0.1 to 3.0 weight % Cu or AgPdTi alloy thin films containing 0.5 to 3.0 weight % Pd and 0.1 to 3.0 weight % Ti. At the wavelength 650 nm, the optimum film thickness of AgPdCu alloy thin film is 5 to 18 nm and the optimum film thickness of AgPdTi alloy thin film is 10 to 25 nm.
