Abstract: PROBLEM TO BE SOLVED: To provide a color display device showing a bright image with improved luminance and improved definition. SOLUTION: In an achromatic polarizing plate 2, an undesirable polarized light component suffers multiple reflection on the phosphor face of an FED1 and light polarization disappears. A desired polarized light component as part of the light which is reflected and retroreflectively enters the achromatic polarizing plate 2 is transmitted while the rest of undesirable polarized light is reflected again. By the repetition of the process, the amount of transmitted light increases to improve the luminance. By controlling the gap between the achromatic polarizing plate 2 and the phosphor screen of the inner glass of the FED 1 to 0.7 mm, a clear image can be obtained even for small characters with almost no influences of blurring even when the image contains a picture and characters.

Abstract: PROBLEM TO BE SOLVED: To simultaneously realize higher image quality, larger screen size and smaller thickness, by forming light emitting pixels near display element boundaries in positions corresponding to the thickness of a transparent display plate. SOLUTION: A unit display 1 is formed by arranging plural phosphor pixels 22aa to 22jj of nearly a square shape in a matrix form as the light emitting pixels on the inside surface of front surface glass 21 having a flat surface. The light emitted from the phosphor pixels 22aa to 22jj of the large-sized flat display arranging plural unit displays 1 in a matrix form is released without scattering at the boundaries with the adjacent glass up to nearly about 45 deg. from forward within the front glass surface glass 21. At the time of forming the large-sized screen in such a manner, the phosphor pixels 22aa, 22ab, 22ba, 22aj, etc., at the peripheral edges are formed in the positions on the side inner by the distances nearly equal to the thickness of the front surface glass 21 from the boundary between the unit displays 1. As a result, higher image quality equal to the image quality of the case where one sheet of the seamless glass is used can be obtd.

Abstract: PURPOSE:To obtain a highly reliable moisture sensor by making a copolymer layer of poly methylglutaminate and polyurethane hard near a melting temperature on an inorganic insulating substrate to laminate the same copolymer layers in such a manner that they can be hardened by heat. CONSTITUTION:SiO2 and SiN3 are laminated on an Si substrate 1 by a CVD method. A copolymer of poly methylglutaminate and polyurethane is diluted by demethylformamide DMF and applied on the substrate in rotation and hardened near a melting point to form a ground layer 4. Then, an Au electrode 5 is deposited on the layer and the same copolymer is diluted to 50% by volume by DMF and applied on the electrode 5 to form a moisture sensitive film 6 by drying at 80 deg.C. An Au electrode 7 is deposited on the film 6. The work is separated into elements with a dicer. The moisture sensor thus obtained provides a higher response speed and a smaller hysteresis and allows combination with an Si element in a process. It also has a long-time reliability with a better adhesion to the substrate.

Abstract: PURPOSE:To enhance durability by preventing the heat shock destruction of a protective layer at the time of high speed printing by a method wherein the constitutional material of the protective layer formed on a heat generating resistor consists of two kinds of materials and the component ratio of two kinds of materials is changed over three layers upwardly from the surface of a resistor. CONSTITUTION:A glaze layer 2 is formed on a ceramic substrate 1 and a heat generating resistor layer 3, an electric conductor layer 4 and protective layers 5-1, 5-2, 5-3 are successively laminated on the glaze layer 2. When the materials constituting the protective layers are Al2O3 and SiO2, each of the layers is set to a thickness of 5,000Angstrom or more and the composition ratios of the respective layers are set so that the first layer 5-1 in contact with the resistor layer consists of 10-30mol% of Al2O3 and 90-70mol% of SiO2, the intermediate layer 5-2 consists of 40-60mol% of Al2O3 and 60-40mol% of SiO2 and the uppermost layer 5-3 consists of 70-90mol% of Al2O3 and 30-10mol% of SiO2. By this method, the protective layers are not destructed by a heat shock even when high speed printing is performed and the life of a thermal head can be extended.
