The present invention is a cable, which carries signal, having an integrated coiling and reinforcing wrapper. The cable has a segment near an end that is stiffer than the cable generally. This segment can be bent by hand, and once bent, will retain its bent shape. If the flexible part of the cable is wrapped into a coil, or otherwise gathered together, then the stiffer portion can be bent around the gathered portion to secure it in its gathered form.

An electrically conductive wire for deep water transmission includes a first wire portion and a second wire portion. The first wire portion makes up one end of the wire, and is formed from a first metal. The second wire portion is formed from a second metal. The first metal has a higher ultimate tensile strength than the second metal. The first wire portion is used to support the weight of the second wire portion, thereby allowing the electrically conductive wire to be used in underwater or subsea power cables which may be freely suspended from their origin for providing electricity to electrical devices located in deep water or ultra-deep water.

The present invention relates to a composition for forming conductive patterns and a resin structure having a conductive pattern, capable of forming a conductive micropattern on various polymer resin products or resin layers using a simplified process and exhibiting excellent heat dissipation characteristics. The composition for forming conductive patterns comprises: a polymer resin; a non-conductive metal compound represented by a specific chemical formula; and a heat-dissipating material, wherein a metal nucleus is formed from the non-conductive metal compound by the irradiation of electromagnetic waves.

A copper alloy wire rod includes a copper parent phase and short fiber-shaped composite phases which are dispersed in the copper parent phase and which contain Cu.sub.8Zr.sub.3 and Cu, wherein the content of Zr is within the range of 0.2 atomic percent or more and 1.0 atomic percent or less. This copper alloy wire rod can be obtained by including the steps of melting a raw material in such a way that a copper alloy having a Zr content within the above-described range of is produced so as to obtain a molten metal in a melting step, casting the molten metal so as to obtain an ingot in a casting step, and subjecting the ingot to cold wire drawing in a wire drawing step, wherein the wire drawing step and a treatment after the wire drawing step are performed at lower than 500 C.

A method is provided for preparing a wire for installation of a terminal. The method comprises removing an insulating layer from a conductor to expose a portion of a conductor. The method further includes attaching a conductive foil layer to a portion of the exposed portion of the conductor by applying pressure to the conductive foil layer. Terminated wires are also provided.
