Diffusion barrier for implantable electrode leads
A process for producing an electrical conductor structure that involves embedding at least one metallic conductor track and at least one heating conductor in an electrically insulating substrate, and producing an electric current in the heating conductor so that a first layer of the substrate and a second layer of the substrate fuse in an area surrounding the heating conductor, to seal an interface between the two layers. A conductor structure is also disclosed, in particular in the form of an implantable electrode lead.
PHOTOELECTRIC COMPOSITE CABLE AND COMMUNICATION SYSTEM

METHOD FOR MANUFACTURING TERMINAL-EQUIPPED ELECTRIC WIRE
A method for manufacturing a terminal-equipped electric wire includes a step of crimping a first terminal to one end of an electric wire, a step of crimping a second terminal to the other end of the electric wire with a tubular seal member, a first waterproofing step of providing, at the one end of the electric wire, an anticorrosion member that covers an element wire bundle of the electric wire, and a second waterproofing step of providing, at the other end of the electric wire, a sealing member so as to fill gaps between conductive element wires of the element wire bundle in a tubular insulating sheath. The second waterproofing step is performed after the first waterproofing step is performed.

METHOD FOR MANUFACTURING TERMINAL-EQUIPPED ELECTRIC WIRE
A method for manufacturing a terminal-equipped electric wire includes a step of crimping a terminal to one end of an electric wire, a step of crimping another terminal to the other end of the electric wire, and a waterproofing step of providing a sealing member at the other end of the electric wire so as to fill gaps between conductive element wires of an element wire bundle. The waterproofing step includes, in this order, a step of applying a resin to the element wire bundle to block at least a part of an inner portion of a tubular insulating sheath, a step of waiting during curing of the resin or until the curing is completed, and a step of applying the moisture curable resin to the element wire bundle, blocking a remaining portion of the inner portion of the insulating sheath, and curing the resin.
ELECTRIC ENERGY TRANSMISSION ALUMINUM PART AND MACHINING PROCESS THEREFOR
An electric energy transmission aluminum part and a machining process therefor including an aluminum conductive device (1) and an aluminum cable, with the aluminum cable including an aluminum conductive core (2) and an insulation layer (3) cladding a surface of the aluminum conductive core (2). An exposed section of the aluminum conductive core (2) with the insulation layer (3) stripped from the aluminum cable and at least part of the aluminum conductive core (2) clad with the insulation layer (3) are crimped inside the aluminum conductive device (1).
