Abstract: The present invention provides a substrate for photoelectric conversion devices including an undercoating film and a conductive film that are formed sequentially on a glass sheet. Chloride fine particles are present in the undercoating film or at the interface between the undercoating film and the conductive film. Convex portions are formed on the surface of the conductive film above the chloride fine particles.

Abstract: The present invention provides a method of manufacturing a glass sheet with a thin film. In the method, a coating-film forming gas including a chlorine-containing compound is supplied onto a glass containing an alkali component to generate chloride fine particles containing the alkali component while forming a thin film to allow the chloride fine particles to be included in the thin film or to adhere to the surface thereof, and thereby the surface of the thin film is provided with concavities and convexities. The present invention also provides another method of manufacturing a glass sheet with a thin film. In the another method, a coating-film forming gas including a silicon-containing inorganic compound and an organic gas is supplied onto glass to generate silicon-containing fine particles while forming a silicon-containing film and thereby the silicon-containing fine particles are allowed to adhere to the surface of the silicon-containing film.

Abstract: The present invention provides a low emissivity glass including a first layer containing silicon oxide as its main component, a second layer containing tin oxide as its main component, a third layer containing silicon oxide as its main component, and a fourth layer containing tin oxide as its main component that are formed on a glass sheet with a thickness of at least 6 mm. The low-emissivity glass has a haze ratio of 0.7% or lower. In this low emissivity glass, the glass ribbon has a surface temperature of at least 700° C. when the first layer is deposited and a surface temperature of at least 640° C. when the second to fourth layers are deposited. It can be produced by a method involving thermal decomposition of a coating-film depositing material, for instance, by a CVD method.

Abstract: Light-colored high-transmittance glass is provided which is made of a composition containing, as coloring components, on a weight percent basis, 0.02 to 0.06% (excluding 0.06%) total iron oxide based on Fe2O3, less than 0.024% FeO, and 0 to 0.5% cerium oxide and having a ratio of FeO based on Fe2O3 to the total iron oxide of less than 40%. The light-colored high-transmittance glass has a solar radiation transmittance of at least 87.5% and a visible light transmittance measured with the illuminant C of at least 90% when having a thickness of 3.2 mm. A glass sheet with a conductive film also is provided which includes a transparent conductive film formed on a surface of a glass sheet formed of the light-colored high-transmittance glass.

Abstract: A glass substrate having a transparent conductive film of SnO2 is disclosed, in which the transparent conductive film is prevented from developing hair cracks even when it has a thickness of 5,000 Å or larger. The glass substrate comprises an alkali-containing base glass plate 10 having a smooth surface and, formed thereon in this order, an undercoat 12 for imparting roughness which has a thickness of 150 Å or larger and is made of a crystalline metal oxide, a continuous alkali barrier film 14 made of SiO2 and having such a small thickness as to reflect the surface roughness of the undercoat, and a transparent conductive film 16 made of SnO2 doped with one or more appropriate impurities and having a thickness of 5,000 Å or larger. The transparent conductive film has an adhesion strength of 37 mN or higher as measured in accordance with “Adhesion Test for Thin Film Deposited on Glass Substrate ” as provided for in JIS R3255-1997.

Abstract: A light controlling device comprising a pair of substrates, a viscoelastic or elastic dispersing medium containing fine particles aligned in an approximately constant direction, and a way for applying a shear stress to the viscoelastic or elastic material. The device can control light transmission in non-stage by applying a shear stress to the viscoelastic or elastic material to incline the direction of the alignment of particles with respect to the incident light.

Abstract: A signal light comprising a light source and a liquid crystal means. The liquid crystal means is disposed between the light source and a viewing area of the signal light for blocking and transmitting light according to a given electrical input. The signal light further includes means for energizing the light source when the liquid crystal means transmits light and for de-energizing the light source when the liquid crystal means blocks light.
