Abstract: A structure for a thin-film electroluminescent (TFEL) device includes an EL phosphor layer sandwiched between a pair of insulator stacks, at least one of the stacks including a thin layer of silicon oxynitride in direct contact with the last grown side of the phosphor layer and a second thicker layer of barium tantalate. The silicon oxynitride layer has high resistivity, and when combined with a second insulator having a high dielectric constant, such as barium tantalate, produces an increase in luminance of the phosphor layer at conventional voltages. Both insulator stacks may include a silicon oxynitride layer, but this layer is in contact only with the last grown side of the EL phosphor layer. On the other side of the EL phosphor layer the high dielectric constant layer lies between the silicon oxynitride and the EL phosphor layer.

Abstract: The invention is a method of manufacturing a dental restoration from a polymerizable resin or composite resin with an alloy structure, or a method of manufacturing an alloy substructure-reinforced dental restoration. An alloy structure or substructure is first coated with a liquid, vitrifiable ceramic layer. To ensure against crazing in the ceramic layer upon vitrification, the ceramic and alloy have generally similar coefficients of thermal expansion. After vitrification, the ceramic becomes a ceramic bonding layer. Micropores are then formed on that layer, as by sandblasting or by etching with a suitable etching acid. A silane coupling agent is then applied to the micropore-containing ceramic bonding layer. Finally, the silane coupling agent is overlain with a polymerizable resin or composite resin material, and the resin or composite resin is polymerized.

Abstract: Bent and/or toughened silver coated glass having light transmission is produced by depositing layers of additional metal over, or both under and over, the silver layer. When the additional metal is used over the silver layer, it is selected from aluminium, titanium, zinc and tantalum. When the additional metal is used both under and over the silver, it is selected from aluminium, titanium, zinc, tantalum and zirconium. The additional metal is used in an amount such that the light transmission of the coated glass increases on bending and/or toughening. The bent and/or toughened coated glass is useful for architectural glazing and as vehicle windows.
