  • Publication number: 20110247929
    Abstract: A diamond electrode having an oxidation resistant diamond film which will not separate from the electrode during electrolysis with highly oxidizing materials. The thickness of the diamond film is 20 pm or more and the diamond film should preferably cover opposite side surfaces of a substrate in such a manner as to also cover end surfaces 2a of the substrate. The surfaces of the substrate are covered with a plurality of diamond layers to form the film using repeated steps of forming separate diamond layers with each diamond layer having a thickness of 10 to 30 pm on one of the surfaces of the substrate and then forming a diamond layer having a thickness of 10 to 30 pm on the other surface of the substrate. Thus, it is possible to form a nonporous surface of diamond layer and prevent deterioration of an electrode caused by the separation of a diamond film.

The metal stearate is applied either as a solid layer on the solder particles or as contact surfaces or is present as a dispersion or solution in a binder. Advantageously, such materials allow one to avoid the use of classical fluxes. In particular, non-resin solder materials can be provided. A simplified storage and processability of the solder materials results, while at the same time producing comparatively better solder connections. The ability to use metal stearates as a flux is achieved if the first oxide of the metals used is formed from pure metal at lower oxygen activity (ao) than the first chromium oxide of chromium, preferably lower than the first titanium oxide of titanium, and if the metal stearate is present in a sufficient amount.

  • Publication number: 20110005808
    Abstract: Hybrid conductors capable of achieving enhanced conductivity and current capacity over a wide range of frequencies are disclosed. The hybrid conductors may be used in electrical or thermal applications, or combinations of both. One method of fabricating such hybrid conductors includes complexing conductive metal elements (e.g., silver, gold, copper), transition metal elements, alloys, wires, or combinations thereof, with carbon nanotube materials. In the alternative, the hybrid conductors may be formed by doping the carbon nanotube materials in salt solutions.

  • Publication number: 20100294537
    Abstract: To produce an aluminum wire covered with copper, capable of retaining its original electrical and mechanical properties when used in environments in which the temperatures exceed 150° C., the wire is produced by a method during which a material foreign to copper and to aluminum is introduced in a small amount at the interface between the aluminum core and the copper layer. The material has the effect of retarding the precipitation of copper in the aluminum and the growth of Guinier-Preston zones. The wire is produced by a known method of reducing the diameter of a composite bar and the foreign material is introduced into the interface between the copper and the aluminum during production of the composite bar so as to be present in trace amounts after reduction of the diameter.

    Abstract: Provided is a composite electric wire, which is intended to realize a light weight and improve a mechanical strength at the same time and which is enabled to improve the reliability by avoiding the problem of oxide coating or electric erosion so that the electric wire may be easily handled for use as a car-mounted wire harness. The composite electric wire comprises an electric wire body (W) composed of center conductors (AL) and outer-layer conductors (CU) arranged to extend in a Z-direction along the outer circumferences of the center conductors (AL) and to enclose the center conductors (AL). In the electric wire body (W), the center conductors (AL) composed of copper-coated aluminum element wires (20) of a (1+6) number are sectionally positioned at the center portion of the electric wire body (W) in an X-Y plane, and the outer-layer conductors (CU) composed of twelve copper element wires (10) are positioned in the outer circumference portion arranged around the center portion of the X-Y plane.
