Tadahiro Furukawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20020093610
    Abstract: The present invention includes the steps of forming a reflecting member having roughness on a surface thereof above a substrate and of transferring the reflecting member onto a film with an adhesive layer interposed therebetween. For example, an organic insulating layer having roughness on a surface thereof is formed above a glass substrate as removable, and then a metal layer is formed on a rough surface of the organic insulating layer, thus forming a reflecting member. Then the reflecting member is transferred onto the film with the adhesive layer interposed therebetween.

  • Patent number: 6413693
    Abstract: A method for transferring a transparent conductive film onto one surface of a sheet base material made of a plastic material, wherein the transparent conductive film as an object to be transferred is preliminarily formed on a substrate side which is superior in heat resistance to the plastic material, the transparent conductive film being sandwiched between a peelable layer which can be peeled off at the time of transfer and a protective film for protecting the transparent conductive film on the substrate side which is superior in heat resistance to the plastic material.

  • Patent number: 6340545
    Abstract: A photosensitive resin composition and a photosensitive liquid for forming colored images are produced from (1) a resin comprising molecules having carboxyl groups and (2) an arene compound, [(Ar)(CpM)n]n+nX− wherein Ar denotes an aromatic compound; M denotes a metal cation; Cp denotes an anion of cyclopentadiene; X denotes an anion; and n denotes a positive integer. Especially, an arene compound, [(Ar)(CpM)2]2+2X−, can realize a photosensitive resin composition with excellent stability and photosensitivity, a photosensitive liquid for forming colored images with excellent light resistance, and color filters.

  • Patent number: 6203951
    Abstract: A reflection-type color filter (30) is disclosed, in which light coming into one surface of a color filter layer (36) is reflected by a reflective layer (40) and allowed to pass through the color filter layer (36) twice. Colored patterns of the color filter layer (36) include resin such as polyimide and dye for dyeing the resin. The thickness of the colored patterns is 0.7 &mgr;m or less. In order to enhance light resistance, it is effective to increase the content of dye with respect to resin. The value of 0.7 &mgr;m is established in consideration of enhancement of optical characteristic and light resistance of the color filter used in the reflection type liquid crystal display device. In order to enhance light resistance, more preferably, a metal complex is added to the resin.

  • Patent number: 5246804
    Abstract: The invention relates to a technique for retouching a pattern which is formed on one side of a substrate and which partially has defects. A method of retouching the pattern, according to the invention, comprises coating the one side of the substrate including the pattern, with a retouching protective membrane, exposing the one side of the substrate, with reference to portions having defects, filling the portions of the exposed one side of the substrate, with retouching material, and removing the retouching protective membrane. One of the retouching protective membrane and the retouching material is made of water-soluble material, while the other is made of oil-soluble material.

  • Patent number: 5176971
    Abstract: A technique related to color filters to be arranged on the light-receiving surface of a color liquid crystal display device, color video camera, and the like. The color filter consists of a substrate (10) and a colored filter layer (12) formed thereon. The colored filter layer (12) comprises, for example, three groups of filter picture elements (14R), 14G, 14B) having spectral characteristics respectively corresponding to red, green and blue. Each group of filter picture elements are made of polyimide resin and dye contained therein. Further, each group of the filter picture elements (R, G, B) are arranged in direct contact with one surface of the substrate (10) without using any intermediate protecting film. The first group of filter picture elements patterned on one surface of the substrate (10) are subjected to heat treatment at a high temperature of about 250.degree. C., for example, to increase their resistance against the solvent.
