Abstract: In a method of producing a device having at least one optical waveguide on a substrate, two transparent layers are formed one on top of the other on the substrate. The material of the two layers is selected so that the melting point of the material of the second layer is lower than that of the material of the first layer, but has a higher refractive index than the first layer.

Consistent reproductions of a composite image are produced on a paper web, and registry between the image and an embossed screen is maintained, by preshrinking (e.g., reducing the moisture content of) the paper prior to printing the composite image on the paper web. Preshrinking the paper prevents the subsequent ink drying operation from causing shrinkage of the paper and concomitant variations in the image, permitting inline formation of a screen in accurate registry with the image.

Abstract: An x-ray imaging screen is disclosed comprised of a thermoplastic film support having a planar coating surface and a fluorescent layer coated on that surface. The film support includes an integral lip at its outer boundary extending above the planar coating surface and along peripheral edge portions of the fluorescent layer to protect the fluorescent layer from wear and delamination from the film support. After coating the fluorescent layer on the planar surface of a film support in forming the screen, the coated film support is cut to size by locally heating the film support above its softening point. A softened portion of the film support is caused to flow over the peripheral edge of the fluorescent layer to form the integral lip while cooling the softened portion of the film support immobilizes the integral lip along the peripheral edge of the fluorescent layer, thereby providing a lateral protective buffer for the fluorescent layer along its peripheral edge.

Abstract: A method is described for the vacuum-coating of substrates, such as glass plates, foils, plastics substrates for optical discs etc., in which the substrates are introduced into a vacuum-coating arrangement and are vacuum-coated in accordance with a PVD (physical vapour-deposition) process such as for example cathode sputtering or vapour-deposition. In order to avoid pinholes in the coating the method is carried out in three steps, namely a first PVD step, in which the substrates and any particles adhering thereto are coated; a particle-displacement step in which the coated particles are displaced from their initial positions on the substrate; and an additional, second PVD step, in which the substrates are coated a second time to cover the defects formed in the coating by adhering particles in the first coating step.

Abstract: A method for producing a light-transmissive printed substrate is provided. The substrate is printed with a predetermined pattern of a light-transmissive phase change ink which initially transmits light in a non-rectilinear path. When the pattern of solidified phase change ink is subsequently reoriented to form an ink layer of substantially uniform thickness, a printed image layer is formed which will transmit light in a substantially rectilinear path and is suitable for overhead projection.In some instances the adhesion between the ink image layer and the substrate is not as high as is desired. This problem can result in delamination of the ink from the film under certain conditions. In order to overcome this problem, an intermediate optically clear adhesion promoting layer is introduced between the light-transmissive phase change ink and the base substrate.
