Abstract: A connection method for connecting an end of a signal wire (53) of a cable (51) to the connecting face of a contact (59) of a connector (52). The lengthwise direction of the connecting face of the contact (59) and the lengthwise direction of the signal wire (53) are mutually matched in connection. The end of the signal wire (53) is pressured against the connecting part by a pair of electrodes (69A, 69B) disposed in mutual separation in the lengthwise direction of the signal wire (53), and an electric current is passed between the pair of electrodes (69A, 69B). Thereby, the end of the cable (51) and the connecting part are mutually welded.

Abstract: A conductive pattern made of copper foil is formed on a base material in each of a plurality of laminated flexible printed circuit boards, and a land is formed to expose the conductive pattern at a predetermined position in the base material. The plurality of flexible printed circuit boards are laminated to adjust each land, and the conductive pattern of each flexible printed circuit board is connected through the each land.

Abstract: In a connection method for connecting an end of a signal wire (53) of a cable (51) to the connecting face of a contact (59) of a connector (52) the cable (51), in which the lengthwise direction of the connecting face and the lengthwise direction of the conductor (53) are mutually matched in connection, the end of the signal wire (53) is pressured against the connecting part by a pair of electrodes (69A, 69B) disposed in mutual separation in the lengthwise direction of the signal wire (53) and an electric current is passed between the pair of electrodes (69A, 69B), and thereby the end of the cable (51) and the connecting part are mutually welded.

Abstract: A wire harness includes a flat cable having a trunk portion formed by covering a plurality of parallel electric wires with an insulating coating by integral molding, a plurality of branch portions formed by branching the trunk portion, and a joint device for connecting not less than two electric wires of the plurality of electric wires constituting the trunk portion to electrically short-circuit the branch portions.

Abstract: A junction between the portion of wiring of an FPC, which is not covered with a cover layer, is directly connected to a connection plate tip incorporated in a terminal attachment by one of resistance welding, ultrasonic welding and laser welding.

Abstract: A network system for transmitting vehicle data has a bidirectional multidrop ring in which data communication between data transmitting nodes and corresponding data receiving nodes is carried out even if a breakage or some other trouble occurs at a portion of the multidrop ring. This system ensures safe and reliable control of various vehicle loads for a long period of time. At least one multidrop bus or at least one further bidirectional multidrop ring may be electrically connected to the first-mentioned bidirectional multidrop ring, thereby widening the applicability of the system to the control of vehicle loads.

Abstract: A laminated insulation paper of the type having two cellulose layers separated by a plastic layer is formed with through holes in the plastic layer such that the respective cellulose layers may contact one another through the through holes. The insulation paper is formed by pressing heated, rounded pins into one of the cellulose layers while backing the other layer until the two cellulose layers are contacted through the hole thus formed in the plastic layer.

Abstract: A POF cable line which comprises a steel pipe and three cable cores drawn in the steel pipe. At least one curved offset section is arranged on the steel pipe at a part spaced from a cable joint at a predetermined distance, with a straight portion of the steel pipe interposed therebetween. The curved offset section prevents the cable cores in the part of the steel pipe from snaking hard and consequently prevents the insulation paper in the part from making soft spots or creases. The snaking occurs easily in the offset section when the cable core thermally expands.
