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 Fe O , less than 0.024% FeO, and 0 to 0.5% cerium oxide and having a ratio of FeO based on Fe O 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.

Light-colored glass of high transmittance and method for production thereof, glass plate with electrically conductive film and method for production thereof, and glass article

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

Glass substrate having transparent conductive film

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.

Light controlling device and process for controlling light transmission

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.
