A machining system includes an application device that applies a photocurable resin to surfaces of a plurality of linear objects provided in a workpiece; a curing device that brings the linear objects, to which the photocurable resin has been applied by the application device, into close contact with each other in radial directions and that radiates light onto the photocurable resin, which has been applied to the linear objects brought into close contact, thus curing the photocurable resin; and a machining device that machines the workpiece, in which the plurality of linear objects have been bound together through the curing of the photocurable resin performed by the curing device.

The present invention provides a connection structure and a manufacturing method therefor capable of increasing reliability of a connection part compared to the prior arts. A connection structure according to the present invention includes a plurality of conductive members, a connection part that electrically connects the conductive members, and an electrically insulating molded body in which the connection part is embedded. It is thereby possible to physically reinforce the connection part of the conductive members, keep the connection part in a hermetically sealed condition, thereby prevent corrosion and increase reliability compared to the prior arts.

The invention relates to a method for manufacturing a cable bundle. At least one provided first cable is completely coated circumferentially on an outer side of the insulating sheath of the first cable with a hot-melt adhesive. In a further step, the first cable is positioned so that it touches a provided second cable over at least a partial length of the cables. In a further step, at least one local adhesive connection is produced between the first cable and the second cable along a partial length of the cables by locally melting the hot-melt adhesive on the first cable.

Disclosed are a joining structure of different kinds of conductors, a joining method of different kinds of conductors, and a joint of power cables capable of improving joining reliability of a junction of the different kinds of conductors.

A method of forming a plurality of individual heating cables sets includes creating at least a portion of a master cable set by coupling alternating sections of cold and hot cable section, each section of cold cable section having a length twice a model cold cable section length and each section of hot cable section having a length twice a model hot cable section length. A continuous metallic ground sheath is applied about substantially all of the master cable set and a continuous outer jacket is applied about the continuous metallic ground sheath. The master cable set is segmented at defined locations to create a plurality of individual heating cable sets having an overall length of the model hot cable section length plus the model cold cable section length.

Bundled cables and methods for preparing bundled cable are disclosed herein. In the method, a plurality of subunits is wound about a central member. The subunits include a subunit jacket made of a first thermoplastic composition and has a first outer surface, and the central member includes a central member jacket made of a second thermoplastic composition and has a second outer surface. A metal element is provided at an interface of the second outer surface and the first outer surface of the subunits. The metal element is heated such that at least one of the first thermoplastic composition or the second thermoplastic composition forms bonds with the other of the first thermoplastic composition or the second thermoplastic composition.

An electrical cable manufacturing method includes: in a joining device including a first facing surface and a second facing surface facing each other in a first direction, and a pressing member and a vibrating member facing each other in a second direction, setting an interval between the first facing surface and the second facing surface to a first distance; placing core wires between the first facing surface and the second facing surface having the interval set at the first distance; and joining the core wires by ultrasonic vibration. The core wires include core wires having different outer diameters. The first distance is larger than a maximum value between values of outer diameters of the core wires and smaller than the sum of the maximum value and a minimum value.

A system, apparatus and method for thermal treatment of surface bonding optical is provided. An optical patch cord is surface bonded via thermal treatment with a tracer optical fiber which provides patch cord tracing in a bonding apparatus. During the process, the optical patch cord is also thermally treated to have the mechanical stress contained in its jacket relieved by rollers in the bonding apparatus to solve the patch cord shrink-back problem.
