  • Patent number: 6656523
    Abstract: A solar-control glass that has acceptable visible light transmission, absorbs near infrared wavelength light (NIR) and reflects midrange infrared light (low emissivity mid IR) along with a preselected color within the visible light spectrum for reflected light is provided. Also provided is a method of producing the improved, coated, solar-controlled glass. The improved glass has a solar energy (NIR) absorbing layer comprising tin oxide having a dopant such as antimony and a low emissivity control layer (low emissivity) capable of reflecting midrange infrared light and comprising tin oxide having fluorine and/or phosphorus dopant. A separate iridescence color suppressing layer as described in the prior art is generally not needed to achieve a neutral (colorless) appearance for the coated glass, however an iridescence suppressing layer or other layers may be combined with the two layer assemblage provided by the present invention.

  • Patent number: 6645029
    Abstract: Disclosed are color filter producing method/apparatus for producing a color filter by ejecting onto a substrate ink from an ink-jet head having a plurality of nozzles arranged substantially in a first direction while relatively scanning the ink-jet head and the substrate in a second direction substantially perpendicular to the first direction, so that filter elements adjacent in the second direction may be colored to have different colors. In the method/apparatus, before the coloring, landing locations for the plural ink dots to be ejected to color the filter elements, are measured and based on the measurement results, ejection timings for the plural nozzles are adjusted so that the plural ink dots land along the center line of each of the filter elements in the first direction. Therefore, it is possible to provide a color filter producing method whereby, during the production of a color filter using the ink-jet method, the occurrence of color mixing can be reduced, and to provide an apparatus therefor.

    Abstract: In the method of fabricating a CRT including a sputtering method for forming an anti-static layer and a spin-coating or spray-coating method for forming an anti-reflection layer on a CRT panel, a method of fabricating a low-resistance, anti-reflection CRT is characterized by applying a silicon oxide (SiO2) coating between the anti-static layer and the anti-reflection layer by a sputtering method. As a result, the CRT has enhanced strength of layers and a low surface resistance. Also, the screen is provided with a charge protection function in the surface, with reflectivity of an external light being mitigated. As a result, it is possible to enhance the contrast characteristics of the screen, to avoid leaving fingerprints on the screen, and also to eliminate unpleasant feeling of static electricity.

  • Patent number: 6071623
    Abstract: The invention relates to a hydrophilic article having (a) a substrate; (b) a first layer formed on the substrate; and (c) a second layer formed on the first substrate. The first layer contains (1) an amorphous silica and (2) at least one first amorphous metal oxide selected from titania and alumina. The second layer has (1) a matrix phase constituted of a crystalline titania and at least one second amorphous metal oxide and (2) a dispersed phase constituted of ultrafine particles made of at least one material selected from silica and alumina. The hydrophilic article is excellent in durability, since the second layer is superior in adhesion to the first layer.

  • Patent number: 6017580
    Abstract: A method is provided for making mirrors having enhanced reflective layer resistance to corrosion. The reflective layer of the mirror, typically silver, is contacted, preferably simultaneously, with a first solution containing a specific cation and a second solution containing a specific anion, or alkaline material which forms hydroxyl ions, the specific cation and specific anion or hydroxyl ion reacting to form a water insoluble precipitate on the silver surface. The mirror may then be painted to provide additional corrosion resistance to the mirror. The method eliminates the need for a copper layer on the silver surface and the method may be incorporated into existing mirror production lines as a replacement for the copper layering step. Also provided are an apparatus for making the mirrors and the mirrors made using the method and apparatus of the invention. A preferred cation containing solution contains tin (e.g., SnCl.sub.2) and a preferred anion containing solution contains hydroxyl ions (e.g., NaOH).
