Abstract:
A method of moving alkali metal ions in a glass substrate to form a glass substrate having an intrinsic alkali metal barrier layer or an enhanced alkali metal layer by applying voltage to at least one of the surfaces of the substrate such that at least a portion of the alkali metal ions, alkaline earth metal ions, or the combination thereof in the at least one surface move into the thickness of the glass substrate.
Abstract:
A method (100) for creating an optical structure for infrared applications includes forming (102) a layer of chalcogenide glass material upon a substrate (210), and applying (106) a patterned stamper (214) to the layer of chalcogenide glass material, in the presence of heat, the patterned stamper (214) causing the layer of chalcogenide glass material to reflow (108) such that stamped features of the patterned stamper (214) are transferred onto the layer of chalcogenide material. The stamped features onto the layer of chalcogenide glass material are used to form one of an optical waveguide, an optical mirror, digital video disk data, compact disk data and combinations comprising at least one of the foregoing. The substrate can be plastic, silicon, silicon dioxide or oxidized silicon. Preferably the chalcogenide glass material is AsxSey.

Abstract:
The invention relates to a method of fastening lamellae of an at least partially conducting lamellar material to an insulating substrate (2) containing oxides capable of dissociating into mobile ions of a given charge and into fixed ions of opposite charge, which method comprises the steps of: placing a specimen (1) of the lamellar material against a flat surface of the substrate; causing the oxides of the substrate to dissociate; and subjecting the substrate and the specimen to an electric field by means of an electrode in contact with the substrate and an electrode in contact with the specimen.

Abstract:
Apparatus (12, 12a) and a method for depositing a material on a substrate (G) utilizes a distributor (22) including a heated permeable member (24) through which a carrier gas and a material are passed to provide a vapor that is deposited on a conveyed substrate. The permeable member (24) is tubular and has an electrical voltage applied along its length to provide the heating, and the carrier gas and the material as a powder are introduced into the tubular permeable member for flow outwardly therefrom as the vapor. A shroud (34) extending around the tubular permeable member (24) has an opening (36) through which the vapor flows for the deposition. In one embodiment of apparatus (12), the vapor is deposited on an upwardly facing surface (56) of the substrate, while another embodiment of the apparatus (12a) deposits the vapor on a downwardly facing surface (54) of the substrate.
