  • Patent number: 7955662
    Abstract: An aligned metal-particle film, in which metal particles are aligned in a polymer as a layer with a certain interval in parallel with a substrate is disclosed. The aligned metal-particle film is manufactured by forming a polymer film containing a metal component on a reflecting substrate; and irradiating the polymer film with light at a particular wavelength, whereby metal particles are aligned in parallel with the substrate in the polymer.
    Type: Grant
    Filed: March 20, 2007
    Date of Patent: June 7, 2011
    Assignees: The University of Tokyo, UBE Industries, Ltd.

  • Patent number: 7132373
    Abstract: The present invention provides a method for producing a crystalline metal oxide thin film by first depositing a substantially amorphous metal oxide film, and thereafter, as a post treatment, exposing the film to low temperature plasma in a high frequency electric field at 180° C. or less, and the crystalline metal oxide thin film produced by this method. Because the producing method according to the present invention allows a dense and homogenous crystalline metal oxide thin film to be formed onto a substrate at a low temperature without requiring active heat treatment, a metal oxide thin film having desirable characteristics can be formed without damaging the characteristics of a substrate even if the substrate has comparatively low heat resistance.

  • Patent number: 7005189
    Abstract: A laminate having improved visible light transmittance and abrasion resistance, which comprises a substrate, and a titanium oxide layer, a metal layer and a titanium oxide layer laminated alternately in this order on the substrate in (2n+1) layers (wherein n is a positive integer), wherein an interlayer having a refractive index of less than 2.4 at a wavelength of 550 nm is interposed at at least one interlaminar boundary between the titanium oxide layer and the metal layer.

  • Patent number: 5976684
    Abstract: An organic substrate provided with a light absorptive antireflection film, which contains an organic substrate, and a light absorbing film and a low refractive index film formed in this order on the substrate, to reduce reflection of incident light from the low refractive index film side, wherein the organic substrate has its surface plasma-treated, and a layer made essentially of at least one member selected from the group consisting of silicon, a silicon nitride, a silicon oxide and a silicon oxy-nitride, is formed between the plasma-treated substrate surface and the light absorbing film.

  • Patent number: 5543229
    Abstract: A method of making a heat treated coated glass comprising the steps of: forming a solar control layer or an electroconductive layer on a glass substrate; forming a first protective layer composed of a non-oxide or not completely oxidized, which is transparent in a region of visible light, and which remains transparent even when oxidized, to provide a glass coated with a multi-layer comprising at least two layers including said solar control layer or an electroconductive layer and said first protective layer; and performing heat-treatment for said coated glass.
