  • Patent number: 6468599
    Abstract: An organic polymer film can be completely decomposed and removed from a substrate surface by exposing the film to ultraviolet radiation having a wavelength of 180 nm or less. Also, ultraviolet radiation not longer than 180 nm in wavelength is scarcely transmitted through a transparent conductive oxide such as ITO and, thus, can be used for eliminating a defective polyimide alignment film formed on a color filter substrate and an array substrate having a transparent electrode pattern of ITO formed on the surface of a pigment portion and a TFT structure, respectively. According to the present invention, the defective alignment film on the substrates can be removed completely without any damage such as discoloring of the pigment portion and/or changing the TFT characteristics.

  • Publication number: 20020150722
    Abstract: Disclosed are an antiglare film having a high level of anti-scintillation properties, high sharpness of transmitted images, high light transmittance (total light transmittance), and a high level of external light reflection preventive properties, and a process for producing the antiglare film. A resin and non-agglomerative particles having a specific particle diameter are selected so that the difference in refractive index between the resin and the particles is 0.05 to 0.15. The resin and the non-agglomerative particles are brought to a coating composition using, as a solvent, a good solvent for the resin and a poor solvent for the resin. The coating composition is coated onto a substrate film to form a coating which is then dried. In the course of the drying, as the amount of the good solvent in the coating decreases, the poor solvent acts to cause the gelation of the particles and the resin. Thus, good concaves and convexes can be advantageously formed on the surface of the coating.

    Abstract: A glass substrate is ion beam milled in order to smoothen the same and/or reduce or remove nano-cracks in the substrate surface before a coating system (e.g., diamond-like carbon (DLC) inclusive coating system) is deposited thereon. It has been found that such ion beam milling of the substrate prior to deposition of the coating system improves adherence of the coating system to the underlying milled substrate. Moreover, it has surprisingly been found that such ion beam milling of the substrate results in a more scratch resistant coated article when a DLC inclusive coating system is thereafter ion beam deposited on the milled substrate. Amounts sodium (Na) may also be reduced at the surface of the substrate by such milling.

    Abstract: A vacuum deposition system has been designed to produce thin film based demultiplexers with high throughput and production yields of greater than 25% for use in Dense Wavelength Division Multiplexer (DWDM) systems. The system employs a dense array of high yield fixtures and an ion assisted movable dual electron beam evaporation system. The fixture array increases acceptable yields of narrow band pass filters to 25-75% compared to less than 5% in conventional coating systems used for DWDM. The movable e-beam system allows critical symmetry to be maintained while eliminating significant delays resulting from deposition of two materials from a single electron gun. The vacuum deposition system will enable production of more than 15,000 50-200 GHZ filters which meet specifications for DWDM demultiplexers every 48 hours.

    Abstract: A substrate is coated with a hydrophobic layer(s) that includes, for example, highly tetrahedral amorphous carbon that is a form of diamond-like carbon (DLC), or any other suitable material. In certain embodiments, the exterior surface of the resulting coated article exhibits a surface roughness sufficient so that the article has an initial contact angle &thgr; of at least about 100 degrees. In certain embodiments, the layer has a surface energy of no more than about 20.2 mN/m and/or an average hardness of at least about 10 GPa.

  • Patent number: 6319549
    Abstract: Provided is an improved optical glass fiber, ribbon unit having the capability of providing mid-span access to individual color-coated optical glass fibers contained therein by application of finger pressure from a human hand. The ribbon unit is made of a plurality of coated optical glass fibers each further coated with a cured color-composition; and a matrix material which binds the plurality of color-coated optical glass fibers together, wherein a bonding force between the cured color-composition and the coated optical glass fibers is greater than a bonding force between said cured color-composition and said matrix material, and wherein the matrix material has been selected or formulated to provide a modulus and Tg sufficiently high such that when opposing pressure is applied to the ribbon unit using the fingers of a human hand, the matrix material buckles and separates from said color-coated optical glass optical fibers instead of compressing and absorbing the opposing pressure.

  • Patent number: 6309692
    Abstract: A substrate is placed on a support surface of a table. The support surface has a flatness of 2 &mgr;m or less. The table has a plurality of holes in the surface. A vacuum is created in the holes to bring the substrate into close contact with the support surface. This eliminates deformations of the substrate, such as twisting and curving. A coating die is moved above the table to apply a coating material onto the substrate. Consequently, a coating having a constant thickness is formed on the substrate.

  • Publication number: 20010028918
    Abstract: The method and formula for tinting glass described herein employs a transparent acetate lacquer. The transparent acetate lacquer is derived from a base of cellulose acetate dissolved in an appropriate solvent. Preferably, additional ingredients are added to the formula to provide a lacquer that is easy to apply and which provides superior adhesion to the glass. The method of this invention includes applying a transparent acetate lacquer to glass and allowing the lacquer to dry. Application of the lacquer may be conducted by any conventional method including spraying and brushing. When dried, the lacquer provides excellent tinting properties.

  • Patent number: 6296707
    Abstract: In an apparatus for coating a surface of at least one lens having pair of opposed major surfaces, al least one lens support is coupled to a frame and is rotatable relative thereto. A lens is releasably mounted to the lens support leaving one of the major lens surfaces exposed. A mounting plate is coupled to the frame and is positioned proximate to the lens support. A series of work stations are carried by the mounting plate for sequentially performing work operations on the exposed major surface of the lens. The lens support is indexable relative to the mounting plate to position the exposed lens surface adjacent to each of the work stations in response to commands issued from a controller.

  • Patent number: 6287636
    Abstract: A coating apparatus comprising a plurality of paint supply devices, a mouthpiece for dispensing a paint supplied from the paint supply devices, and a stage for holding a coated object. The mouthpiece comprises a plurality of outlet ports. Also, a coating method comprising relatively moving a mouthpiece and a coated object to coat the coated object with paint in which a diluent is added to the paint to form a paint/diluent mixture upon the start of the coating process. This paint/diluent mixture is used to coat the coated object upon the start of the coating process and until the process reaches a steady state. The flow of diluent is then stopped and the coating process is continued using only the paint in a steady state coating process. The flow of diluent is then started again to form a paint/diluent mixture as the coating process ends. A coating with a highly uniform thickness along the entire length of the coated object is produced by this method.
