Abstract: A multifunctional material having a carbon-doped titanium oxide layer, which has carbon doped in the state of Ti—C bonds, is excellent in durability (high hardness, scratch resistance, wear resistance, chemical resistance, heat resistance) and functions as a visible light responding photocatalyst, is provided. The multifunctional material of the present invention is obtained, for example, by heat-treating the surface of a substrate, which has at least a surface layer comprising titanium, a titanium alloy, a titanium alloy oxide, or titanium oxide, in a combustion gas atmosphere of a gas consisting essentially of a hydrocarbon such that the surface temperature of the substrate is 900 to 1,500° C.; or by directly striking a combustion flame of a gas consisting essentially of a hydrocarbon, against the surface of the substrate for heat treatment such that the surface temperature of the substrate is 900 to 1,500° C.

Abstract: An improved infrared detector element and an improved method for manufactng same is provided. A commercially available rough art wafer of ferroelectric material is ion milled under conditions which provide an extremely thin element with a near flawless detection surface.

Abstract: A duplex coating for substrates that comprises an undercoat of tungsten carbide-cobalt having a strain-to-fracture of greater than 4.3.times.10.sup.-3 inch per inch and a top coat of a ceramic material such as alumina in which the ratio of the thickness of the top coat to the undercoat is from 6:1 to 1:3.

Abstract: A tool having an extended service lift and including a hard metal body, and at least one surface layer composed of at least one hard substance selected from the group consisting of carbides, nitrides, and carbonitrides of titanium and zirconium, and having a chlorine content ranging from a finite amount up to 4 mass percent, the tool being produced by plasma-activated CVD process including: a. positioning the hard metal body in a CVD chamber having means for supplying direct voltage thereto, the hard metal body being connected to the direct voltage supplying means as a cathode thereof, b. introducing into the CVD chamber a reactive gas mixture including a nitrogen-containing substance, a carbon-containing substance, and at least one compound containing at least one of titanium and zirconium, and c.

Abstract: The present invention is a coffee carafe, having a thin base and thin sidewalls formed of a polymer such as polyetherimide, polyethersulphone, or other high temperature polymer having a heated thermally conductive coating applied to a coat receiving portion of the carafe and having characteristics permitting heating of the resinous carafe on a hot plate.

Abstract: There are disclosed a diamond-coated sintered body, comprising a film of diamond and/or diamond-like carbon deposited on the surface of a sintered body of a hard phase composed mainly of a mixture of W.sub.2 C and WC and inevitable impurities and a process for preparing the same.

Abstract: The invention is generally accomplished by mixing non-phosphorous containing metal resinates and phosphorous resinates, forming a coating of the mixture on a substrate and heating the mixture to recover a thin film coating of metal phosphate. The metal resinates and phosphorous resinates are defined as metal-ligand compounds where the ligand is thermally separable. The preferred ligands are carboxylates, alcoholates, and acetylacetonates. The heating decomposes the metal phosphate precursor coating materials to yield a metal phosphate. The phosphorous resinate may comprise an alkyl phosphate, arylphosphate, or a carboxylate substituted alkyl or aryl phosphate. The substituting carboxylic acids may be pure, such as 2-ethylhexanoic acid, mixtures of acids, such as neodecanoic acid, and naturally occurring acids, such as rosin (abietic acid). The metal resinate may be a metal carboxylate, a carboxylate substituted alkoxide, or carboxylate substituted acetylacetonate.

Abstract: A heat treatment sputter-coated glass having on its glass substrate a coating system consisting essentially of a high nickel alloy overcoated with tin oxide and, optionally, undercoated with tin oxide with, or without, a layer of metallic aluminum located between the high nickel alloy layer and the overcoat of tin oxide.
