Abstract: The present invention relates to a glass for freezers and refrigerators and a glass article formed of the glass, and its technical problem to be solved is to secure a sufficient thermal insulating ability, reduce the cost, prevents dew condensation without consuming extra power energy as well as secure desired transparency. In the glass for freezers and refrigerators, a tin oxide film and a silicon oxide film are laminated on a surface of the glass substrate in this order, and a tin oxide film with fluorine added (low-radiation layer) is formed on the silicon oxide film. The glass is installed in a freezer or refrigerator such that a surface of the glass formed with the low-radiation layer faces onto the inside of the freezer or refrigerator. A glass article in which is used one or more sheets of the above glass, such as a multi-layered glass, with improved thermal insulation can be obtained.

Abstract: When a ZnO layer is formed as a dielectric layer on an amorphous layer, a columnar crystal structure of ZnO is put into disorder whereby not only the amorphous layer but also the dielectric layer function as a barrier for preventing the invasion of moisture and gas from outside whereupon durability of a metal layer (Ag) is improved.

Abstract: In an automotive window glass having a pair transparent sheet glasses that are stuck to each other with a transparent resin film, the inner surface of one of the pair of sheet glasses, which faces the transparent resin film, is coated with a heat-ray intercepting film that is composed of any one of the following chemical formulas whose atomic ratios are defined.(A) ZrN.sub.x O.sub.y : 0.5.ltoreq.x.ltoreq.0.8, and 0.8.ltoreq.x+y.ltoreq.1.2(B) TiN.sub.x O.sub.y : 0.2.ltoreq.y.ltoreq.0.8, and 1.4.ltoreq.x+y.ltoreq.1.8(C) CrN.sub.x O.sub.y : 0.1.ltoreq.y.ltoreq.0.8, and 1.4.ltoreq.x+y.ltoreq.1.

Abstract: A cathode-ray tube having a face plate which includes a phosphor layer provided at the inner surface side of a glass plate and an optical interference filter provided between the phosphor layer and the inner surface of the plate. The optical interference filter is constituted by high- and low-refractive index layers. The outermost layer of the optical interference filter in contact with the phosphor layer is an Al.sub.2 O.sub.3 layer or a ZrO.sub.2 layer having a physical thickness of 10 nm or more. The high-refractive index layer of the optical interference filter preferably consists of TiO.sub.2, and its low-refractive index layer preferably consists of Al.sub.2 O.sub.3.

Abstract: A heat ray screening glass according to this invention comprises a sheet glass, a first layer covered on the sheet glass and which is 55 nm to 70 nm thick and has a refractive index of 1.8 to 2.1 at a wavelength of 550 nm, a second layer covered on the first layer and consisting of a TiO.sub.2 film which is 30 nm to 55 nm thick and has a refractive index of 2.3 to 2.5 at a wavelength of 550 nm, and a third layer covered on the second layer and which is 45 nm to 60 nm thick and has a refractive index of 1.8 to 2.1 at a wavelength of 550 nm, wherein the change in color of the light transmitted through and reflected on the sheet ray screening glass is very little, and a comparative high visible light transmittance and a low visible light reflectivity in the glass can be obtained.
