  • Patent number: 5830252
    Abstract: Amorphous metal oxide barrier layers of titanium oxide, zirconium oxide and zinc/tin oxide are effective as alkali metal ion barrier layers at thicknesses below 180 Angstroms. The amorphous metal oxide barrier layers are most effective when the density of the layer is equal to or greater than 90% of the crystalline density. The barrier layers prevent migration of alkali metal ions such as sodium ions from glass substrates into a medium e.g. electrolyte of a photochromic cell, liquid material of a liquid crystal display device contacting the glass surface. The properties of the medium, particularly electroconductive metal oxide coatings, are susceptible to deterioration by the presence of sodium ions migrating from the glass.

  • Patent number: 5512148
    Abstract: A substrate is treated prior to use to induce a near-parallel orientation of a liquid crystal director relative to the substrate. A layer of silica is deposited on the substrate by in-line magnetron sputtering as the substrate is moved past the sputtering target, and the silica-coated substrate is thereafter treated with an alcohol that is selected from one of two classes of alcohols: (1) alcohols having an aromatic ring structure on one end of an aliphatic chain and a hydroxy group on the other end, with or without at least one ether group in the chain, and (2) an aliphatic chain having a hydroxy group at one end and at least one ether linkage in the chain. An example is 2-phenylethanol. The alcohol-treated substrate is covered with a layer of the liquid crystal. The process of the invention induces a tilt to the director of the liquid crystal. The tilt is about 0.5.degree. to 4.degree., as measured parallel to the surface of the substrate.

  • Patent number: 5491379
    Abstract: The method and structure for providing a pair of electrical contact terminals on the back side of an electroluminescent (EL) lamp. The EL lamp has a first conductive layer, a layer of EL material, a first insulating layer, a second conductive layer, a second insulating layer and a film of conductive material, all disposed on a transparent substrate, respectively. The film of conductive material extends around the second insulating layer to come in electrical contact with the first conductive layer. This allows an electrical contact terminal to be established on the film of conductive material, rather than directly on the first conductive layer. The other electrical contact terminal is positioned on the second conductive layer. The second insulating layer serves to electrically separate the two contact terminals.

  • Patent number: 5470606
    Abstract: An antistatic coating was provided on a substrate 10 by dispersing latex particles 12 from a polypyrrole compound in an aqueous solution of a hydrolyzed alkoxysilane compound, after which the dispersion was applied to the substrate. The hydrolyzed alkoxysilane compound was converted to silicon dioxide by means of a treatment at an elevated temperature, thereby forming a matrix 14 in which the latex particles 12 axe dispersed and by means of which the latex particles are adhesively secured to the substrate 10. The antistatic coating can particularly be used on the display screen of a cathode ray tube, and, if desired, said coating can simultaneously be used to reduce the light transmission of the display screen.

  • Patent number: 5464657
    Abstract: A method for coating a moving substrate provides a coating having a chemical composition which varies continuously from the interface with the substrate to the opposite surface of the coating. The method involves directing a vapor coating composition toward a substrate surface and moving portions of the vapor in opposite directions. A vapor coating mixture may include a tin-containing precursor and a silicon-containing precursor. An accelerant, e.g. a phosphorus-containing precursor, may be used with the metal-containing precursors to increase the deposition rate of the coating. The coating deposited on the substrate has regions of continuously varying weight percent of silicon oxide and tin oxide as the distance from the substrate-coating interface increases, with the surface of the coating farthest from the substrate-coating interface being predominantly tin oxide.

  • Patent number: 5403700
    Abstract: A biocompatible thin film electrical component is configured for use in a human body or other ionic liquid environment. A polyimide substrate is bonded to a glass carrier plate sized for handling by automatic equipment and a multiple-layer metal conductor is deposited on the substrate and patterned to define an electrical circuit or biosensor. The polyimide and the glass establish a bond therebetween that withstands handling yet is broken using biocompatible releasing agents and techniques. The polyimide substrate and glass carrier plate preferably have similar thermal expansion properties to reduce the likelihood of fracture and delamination problems during release of the substrate from the carrier plate. An insulation layer covers the metal conductor and, in one embodiment, is made of a polyimide having a cure temperature lower than the temperature at which interdiffusion occurs in the metal layers in the conductor.
