摘要： PURPOSE:To ensure good reliance upon the shield effect by constructing a tape forming jig so that the incoming side has a semicircular opening, while the outgoing side has a spiral opening, which makes the end of a shield tape spiral. CONSTITUTION:A tape forming jig 1a has a semicircular opening 1a1 on the incoming side and a spiral opening 1a2 on the outgoing side, and a conductor 3 and conductor 3 electrically insulated with an insulative substance 4 are parallelly inserted in the M direction, and an Al tape 2 is inserted so as to enwrap them. Tape formation is made while only this Al tape 2 is put alongside the outlet configuration, which is spiral, on the outgoing side of the tape forming jig 1a. Accordingly there is no fear of generation of Al tape 2 forming turbulence owing to the tape forming jig 1a, and it is possible for the Al tape 2 to enwrap the whole cores, which ensures good reliance upon the shield effect.

摘要： PURPOSE:To facilitate the manufacturing of a shield line wire for press welding connection using an asymmetric cross sectional line body by mounting a positioning line on the asymmetric cross sectional line body, and by guiding the asymmetric cross sectional line body by the positioning line. CONSTITUTION:A positioning line 3 is mounted on an asymmetric cross sectional line body 2 made of a conductive resin having an asymmetric cross sectional form, by bonding using a bonding agent, and so on. The asymmetric cross sectional body 2 is guided by the positioning line 3, which is removed from the asymmetric cross sectional line body 2 and wound up, while the asymmetric cross sectional line body 2 is positioned in a predetermined direction by the winding force. Rotation of the asymmetric cross sectional line body 2 can thus be prevented, and its position can be constantly maintained in the same direction, whereby the manufacture of a pressure welding connection shield line can be facilitated and a yield can be improved.

摘要： PURPOSE:To improve the operability in hand of a catheter by burying a laterally wound shield made of metal in a catheter body. CONSTITUTION:A layer of a laterally wound shield 15 made of stainless, for example, is applied on a catheter tube body part 13 to form a highly operable catheter 6. This is formed by burying a stainless wire in the catheter tube body part 13 in such a manner that it is wound thereon in a coil form, and on the top end part 11, the laterally wound shield 15 is not applied to eliminate the rigidity of the catheter. By making the stainless wire into the laterally wound shield type, the delicate motion of the catheter can be easily operated in hand, and the catheter can be easily handled.

摘要： PURPOSE:To obtain a catheter having satisfactory strength and flexibility such that braided element wires never protrude into the inner cavity of the catheter by providing a first inner layer consisting of a hard material and a second inner layer consisting of a soft material on the outside to form an inner layer, burying the braided element wires in the second inner layer, and providing an outer layer on the outside thereof. CONSTITUTION:A catheter is formed of a first inner layer consisting of a hard material such as high density polyethylene, a second inner layer 2 consisting of a soft material such as low density polyethylene on the outside, which has braided element wires 4 buried therein, and an outer layer 3 consisting of a soft material such as low density polyethylene on the outside. To manufacture the catheter, the first inner layer 1 is extruded on a core wire to apply a coat, and then the second inner layer 2 is extruded on the outside of the inner layer 1 to apply a coat. Braiding is applied on the outside of the second inner layer 2, and the braided element wires 4 are throttled by a die and buried in the internal part of the second inner layer 2. As the braided element wires 4 are never buried in beyond the hard first inner layer 1, they never protrude into an inner cavity 5.

摘要： PURPOSE:To manufacture supereccentric drain wire stably and efficiently by supplying conductive resin to a shaping mouth by means of extrusion with missing part at the periphery of the drain wire. CONSTITUTION:A supply path 16 for covering material is formed as a gap bounded by a core 10 and a base metal 13, and a molten and pressurized conductive resin 2 is fed by pressure to this supply path 16 by a screw, not illustrated. A drain wire 1 is supplied while penetrating a through hole 12 in the core 10, and at a shaping mouth 15 the periphery of this wire 1 is covered with the conductive resin 2 extruded. In this extrusive covering process, the resin 2 is not fed evenly over the periphery of the drain wire 1, but is extruded in the condition missing at a part of the periphery, that will enable stable and highly efficient protrusive manufacturing of supereccentric drain wires.

摘要： PURPOSE:To enable a wide improvement in the workability of a terminal by superposing metal tapes between insulation cores and between the insulation cores and conductive cores, and sealingly integrating the superposed parts by welding, thereby forming a shield layer. CONSTITUTION:Metal tapes are superposed between insulation cores and between the insulation cores and conductive cores and a shield layer 9 is formed by sealingly integrating the superposed parts by welding. As a result, at the time of processing of a terminal of shield wire for the force-contact connection thereof for separating the jacket 10 at the terminal part, the metal tapes are not separated from each other. It is thus possible to connect the force-contact connector easily without irregularity of the pitches between the respective cores and to improve the processability of terminal remarkably.

摘要： PURPOSE:To make it possible to take up a filamentary body without entailing its bending nature by making a filamentary body fall in a receiver box through a guide member from a guide roll after lifting the filamentary body up to a specific height by the rotative power of the guide roll and taking up the filamentary body by way of winding and filling it in a coil shape on the bottom of the receiver box. CONSTITUTION:A filamentary body 3 is lifted up to a specific height by the rotative power of a lower part guide roll 4 and an upper part guide roll 5. Subsequently, this filamentary body 3 is guided to fall in a receiver box 7 through a guide disk 6 from the upper guide roll 5 and taken up after it is wound in a coil shape and filled on the bottom of the receiver box 7. By taking it up in such a way, it is possible to have a larger radius of curvature of the winding and to take-up the filamentary body 3 in such a condition to leave little bending nature.

摘要： PURPOSE:To enable continuous printing of a filament body at high speed and stably without use of a doctor knife by providing an ink supply part which feeds ink to tiny holes in a printing roll through a passage in a shaft for rotation of the printing roll. CONSTITUTION:Ink 1 is supplied to tiny holes 10 in a printing roll through a shaft 9 by driving a pump 11, and is allowed to penetrate the internal layer 7 of the printing roll. The ink penetrating the internal layer 7 is supplied to the periphery 8 of the printing roll by a centrifugal force caused by rotation of the shaft 9 and the pumping force of the pump 11, so that the ink is stored in a character recessed part formed on the periphery 8. This stored ink is transferred to a filament body (e.g. electric wire) by a pressing force of a holding roll 5, and characters are continuously printed on the filament body.
