Abstract: Proposed is a high temperature superconducting wire manufacturing method and a high temperature superconducting wire having multiple superconducting layers formed by applying the method. The method includes a stacking process in which a pair of protective layers of superconducting wires including a substrate, a superconducting layer, and the protective layer are stacked such that the protective layers face each other, a joining process in which the protective layers facing each other are diffusion joining together by thermal treatment and become a joining protective layer, an exfoliating process in which a layered structure of an upper portion of the corresponding superconducting layer is removed such that one side of the superconducting layer is exposed to the outside, and an outermost protective layer forming process in which an outer protective layer formed of the same material as the joining protective layer is formed on the upper portion of the exposed superconducting layer.

Abstract: A high frequency signal transmission cable includes a conductor, an insulator provided over a periphery of the conductor, a plating layer provided over a periphery of the insulator, and a sheath provided over a periphery of the plating layer. A crack suppressing layer includes a non-cross-linked polyethylene is provided between the insulator and the plating layer, in such a manner as to remain in contact with the insulator while being provided with the plating layer over an entire periphery of a roughened outer surface of the crack suppressing layer. The crack suppressing layer is unadhered to the insulator. The plating layer is adhered to the crack suppressing layer. The crack suppressing layer suppresses an occurrence of a cracking in the plating layer by bending together with the plating layer while being integral and moving with the plating layer in a longitudinal direction of the cable.

Abstract: Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.

Abstract: A multicore cable inspection method of specifying a correspondence relationship among ends of insulated electric wires exposed from both ends of a multicore cable, the method including: inputting, by capacitance coupling, an inspection signal to the end of the insulated wire to be inspected among the ends of the insulated wires exposed at the one end of the multicore cable; inputting, by the capacitive coupling, each of first and second signals, each of which has a phase different from the inspection signal, to the ends of the two insulated wires other than the insulated wire to be inspected; measuring a voltage of an output signal outputted from the capacitive coupling from each end of the insulated wires exposed at the other end of the multicore cable; and specifying the other-side end of the insulated wire to be inspected. At this time, an amplitude of a signal obtained by adding the inspection signal and the first and second signals is smaller than that of the inspection signal.
