  • Patent number: 5513040
    Abstract: A solar control film having low visible light transmittance and low visible light reflectance is comprised of two or more transparent substrates each bearing a thin, transparent, discontinuous, incoherent film of metal having low visible light reflectance and a degree of visible light blocking capacity, the substrates being so assembled and laminated into a composite that the visible light blocking capacities of the metal films are effectively combined to provide a composite having low visible light transmittance. Performance characteristics are enhanced by providing on one or more of the substrates a transparent coating of high refractive index underlying the metal film. The material of high refractive index is preferably a synthetic high oxygen content oxide of bismuth, which facilitates efficient and economical production of the solar control film.

  • Patent number: 5376455
    Abstract: A high performance, durable sputter coated, heat-treatable glass which after heat-treatment exhibits about 76% or more visible transmittance, a hemispherical emissivity (E.sub.h) of about 0.16 or less, and a normal emissivity (E.sub.n) of about 0.12 or less is formed by sputter coating a layer system on a glass substrate which includes an undercoat and overcoat of Si.sub.3 N.sub.4, a silver layer, and two nickel or nichrome layers on opposite sides of the silver layer, and wherein the lower nickel-based layer is about three times as thick as the other nickel based layer. The increased thickness of the lower nickel-based layer allows the coated glass article to be both heat-treatable, and "low-E" after the heat-treatment. This allows matching with other known glasses in the family of layer components by way of the heat-treatment process.

  • Patent number: 5246787
    Abstract: A coated tool or instrument has a wear-resistant hard coating (7) which is preferably titanium nitride for working organic material which is disposed on a separating layer (9) applied on a basic body (3). The separating layer (9) comprises a ceramic electrically non-conducting material. Such a material is preferably an oxide, nitride or oxynitride of silicon. The separating layer (9) protects the basic body (3) of the tool or instrument of e.g. a non-corrosion resistant steel. During the coating of the basic body (3) with the ceramic material, a pulsating dc voltage is applied to the basic body (3) or its holders. The pulse height is changed during the vapor deposition from high negative values to low negative values.

  • Patent number: 5236791
    Abstract: A magnetic recording medium that uses, as a protective coating layer provided on a magnetic layer for magnetically recording signals, a layer made of a nonmagnetic material consisting of two ore more elements of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W, and one or more elements of N, C, O, and B, or made of a magnetic material consisting of one or more elements of Co, Fe, Ni, and Gd, one or more elements of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W, and one or more elements of N, C, O, B, and Si is excellent in sliding endurance. When the protective coating layer is made of the nonmagnetic material, the magnetic recording medium is also excellent in corrosion resistance, and when the protective coating layer is made of the magnetic material, the spacing between a magnetic head and the magnetic recording medium can advantageously be made large. Both the cases are high in reliability, and suitable for high density magnetic recording.

  • Patent number: 5215832
    Abstract: Mirrors are formed in an environmentally compatible and substantially pollution-free manner by a sputtering process in which a transparent substrate such as glass has first sputtered upon it a primer layer and then a reflective layer of silver or other bright reflective metal. A barrier layer is provided over the reflective layer to protect the latter from corrosive environments. If the transmittance of the reflective layer is greater than zero percent, the barrier layer includes a different bright reflective metal sufficient to reduce the transmittance of the combined reflective and barrier layers to zero percent. The mirror includes a lead free polymeric protective layer spaced further from the transparent substrate than the barrier layer. The inclusion of zinc pigment in the polymeric coating provides sulfiding protection, and the use of an outer sputtered on film of zinc or zinc oxide provides substantial adhesion thereto of the polymeric coating.
