A multicore cable includes a plurality of cables in parallel and is formed by fusion-welding the plurality of cables with a resin jacket. Each of the plurality of cables is formed by winding a shield around a signaling core wire, which is covered with an insulating material, and a grounding core wire. The resin jacket and the shield are stripped so that a stair portion is formed. The stair portion is coated with an electrically conductive adhesive. A vibration is exerted on the grounding core wire, thereby connecting the shield with the grounding core wire with the electrically conductive adhesive. Eventually, the shield and the grounding core wire are bonded with the electrically conductive adhesive. This allows an electrical connection between the shield and the grounding core wire to be maintained in a desirable condition, thus making it possible to suppress a characteristic impedance variation of the signaling core wire caused by an external factor.

Multicore cable and a method of manufacturing thereof

A method of determining supply sequence of products to be processed to an N-step flow shop type production line, where N is an integer N greater than or equal to 2, is disclosed. To optimize the production time of all the products in the N-step flow shop type production line with high precision, the supply sequence of products to be processed to the N-step flow shop type production line is determined by virtually dividing the N steps to 2 virtual steps on the basis of a total number of necessary man-hour of products to be processed, sequencing the supply of the products to be processed in one of the virtual steps to a first step of the N steps in the order of smallness of the required man-hours for the product, storing the product to be processed in the other virtual step in a stack memory as products for which a new supply sequence is to be determined and repeating the supply sequence determining processing recurrently as long as N is greater than or equal to 2 and the stack memory contains stored virtual steps.

Method and apparatusa for determining supply sequence of products ot be

According to the method for terminating a cable and the apparatus used therefor of the present invention, first the thermosetting resin layer of the cable is heat-cured, for example, by laser beam. The heat-cured thermosetting resin layer is lowered in stress and strain at rupture and hence can be easily cut and then this thermosetting resin layer is cut and peeled off.

Method for terminating cables and apparatus therefor

An apparatus for forming and cutting a flat type multi-core cable is disclosed, in which core conductors of a flat type multi-core cable, whose core conductors are previously exposed by exfoliating a part of a jacket therefor, are divided into a plurality of units; the core conductors are formed and cut separately for every unit; and at the same time the pitch of the core conductors is corrected. Further the number and/or the pitch of the core conductors are calculated by using information obtained by the scanning of the core conductors and cables, for which the number of the core conductors is not in agreement with predetermined one, or cables, for which errors in the pitch of the core conductors exceed a certain limit, are excluded as deficiencies.
