The surface treatment method, comprising: a first step of forming, on a copper surface, a nobler metal than the copper discretely; a second step, subsequent to the first step, of forming copper oxide on the copper surface by oxidation with an alkaline solution containing an oxidizing agent; and third step of dissolving the copper oxide so as to be removed, thereby forming irregularities on the copper surface.

Abstract: A gas-adsorbing member is charged in low gas-permeable container (7) through its opening portion, wherein low gas-permeable container (7) is constituted by a hollow cylindrical metal member which is opened at its one end and is sealed at its other end and, also, has body portion (9) extending from the one end to the other end thereof such that the length of the body portion is equal to or larger than the maximum width of the end portions. Then, a sealing member is installed within the opening portion and near the opening portion. Then, the sealing member is molten by being heated. Thereafter, the sealing member within the opening portion is cooled to be solidified, thereby attaining sealing of the opening portion. Thus, it is possible to provide a gas-adsorbing-device fabricating method capable of suppressing degradations of the gas-adsorbing member and capable of reducing the fabrication costs.

In embedding a resistor or capacitor, a passive unit of a resistive film or a capacitive film is first made on one side of a conductive foil.

Abstract: A protective coating is applied on a local region of a surface of a component on which direct deposit of a uniform coating of protective material is impeded due to a complex shape of the region to be covered or inaccessibility or inability to apply a uniform deposition or electrical field therefor. The coating is formed by a foil having a solder backing layer with a thin layer of uniform thickness of the protective material electrolytically deposited on the backing layer, the foil being cut to size corresponding to an area of the local region of the component to be protected. The cut to size foil is positioned and held on the local region of the component to be protected; and fixed in place by melting the solder to fuse the foil to the component and cover the local region.

Abstract: Ceramic bodies are bonded together via a layer of an oxidation reaction product of a molten metal, which metal is present in one or both of the ceramic bodies prior to bonding. At least one of the ceramic bodies comprises a ceramic product formed by the oxidation reaction of molten parent metal (e.g., alumina from molten aluminum) and grown as molten metal is transported through, and oxidized on the surface of, its own oxidation product. One or both of the ceramic bodies used in the bonding process contains surface-accessible channels of residual metal, i.e., metal channels which have resulted from molten-metal transport during the ceramic growth process. When the suitably assembled ceramic bodies are heated in the presence of an oxidant at a temperature above the melting point of the residual metal, molten metal at the surface of at least one of the ceramic bodies reacts with the oxidant so to form a layer of oxidation reaction product which may or may not incorporate at least one filler material.

Abstract: Reinforced structural elements are produced by taking two or more sheets of the same or different malleable metal and applying a pattern of thermally decomposable stop-off material on an interfacial surface, solid phase green bonding the sheets one to another by squeezing them through squeezing rollers and sintering the sheets to improve the metallurgical bond therebetween. The composite can be formed into complex configurations having compound reentrant surfaces and then raised above a predetermined temperature to decompose the stop-off material to generate gas and inflate the sheets contiguous to the pattern. The stop-off material can be chosen to decompose essentially completely at a temperature above the predetermined temperature which facilitates forming prior to inflation or the material can include a portion which decomposes at the sintering temperature of the metallic sheets employed giving a two stage inflation.

Abstract: An assembly (28) of ceramic surfaces (21, 23), particularly refractory metal oxides and carbides, abutting a thin sheet (22) of metal susceptor material are placed in a chamber (10) of an enclosure (14) containing inert gas (36). An r.f. coil (24) is activated by power supply (26) to melt the susceptor (22) and adjacent zones (40, 42) of the ceramic. Reactive gas such as oxygen or a carbonizing gas (38) is then fed to the chamber (10) and reacts with the susceptor (22) to form compounds (47) which disperse and dissolve in the zones (40, 42). On cooling, a strong joint is formed. The susceptor may contain inner perforations (58) and outer perforations (56) to aid in distribution of heat.

Abstract: The present invention relates to a method for producing sandwich type structural components having a honeycomb core interposed between two cover layers. These cover layers are preferably made of fiber reinforced synthetic material. Force introduction points are formed in the structural components by insertion of a core filler mass in the form of a prepolymer which reacts to become a thermoplast. Force introducing connecting elements are connected to the force introducing points by melting these connecting elements into the core filler mass especially by using ultrasonic energy, for example, for an ultrasonic welding operation.
