摘要： PROBLEM TO BE SOLVED: To make a winding pitch of an optical drop cable, etc., which is wound spirally on a DV wire (polyvinyl chloride insulated drop wire), etc., for wiring constant. SOLUTION: An optical drop cable 2 is mode in coiled cylindrical shape, to form an optical drop cable coil 1. The outer circumference of the optical drop cable coil 1 is wrapped tightly with a cylindrical wrap 3, comprising an expandable sheet material. The optical drop cable coil 1 is put on the DV wire between a pole and a house. If the end of the optical drop cable coil 1 is fixed to one end of the DV wire and moved toward the other end, the optical drop cable 2 is wound spirally in the DV wire and the DV wire and the optical drop cable are wired integrally. The optical drop cable coil 1 is wrapped with the cylindrical wrap 3, so that its coiled state is stable. Since the optical drop cable 2 is supplied from the inner winding side (inner circumference side) of the optical drop cable coil 1, the winding pitch of the optical drop cable on the DV wire can be fixed.

摘要： PROBLEM TO BE SOLVED: To provide a wiring method for a drop cable, which can solve the problem that the cable is wasted, loss characteristics in an optical fiber must be considered, and an existing DV wire cannot be used, etc., and to efficiently carry out cable dropping. SOLUTION: A DV wire (polyvinyl chloride insulated drop wire) 4 and an optical drop cable 5 are dropped from an overhead distribution network, comprising a distribution wire 1 and a distribution system optical cable 2 which are installed in parallel with each other, to a house 7 according to a following procedure. First, the DV wire 4 is let through an optical drop cable ring bundle 5', formed by bundling up the optical drop cable 5 into a ring shape. Both the ends of the DV wire 4 are fixed to a pole 3 side and to a house side (a fixing point 9). The cable end of the optical drop cable ring bundle 5' is connected to an outdoor junction box 8 of the house. Then, if the optical drop cable ring bundle 5' is moved toward the pole 3 side, the optical drop cable 5 is supplied from the bundle 5' and automatically wound spirally on the DV wire 4. The neighborhood of the tip of the optical drop cable 5 is fixed to the DV wire 4, and the tip is connected to the distribution wire 1 with a closure 10.

摘要： PROBLEM TO BE SOLVED: To provide an armored submarine cable, where the damaged section of the armor body can be repaired at a lower cost, as compared with before. SOLUTION: The armored submarine cable 1 has a constitution such that many pieces of armor line materials 5 as zinc-plated wires, where corrosionproof plating is applied are wound densely at specified winding pitches in spiral form around a cable body 4 so as to make an armor 2, and that it is covered with a corrosion-proof layer 6 as coal tar. This armored submarine cable 1 is laid at the bottom of the sea, and in case where a damaged part occurs in the armor 2, being moved by waves or an ocean current, an armor member 8 is wound at smaller winding pitches than the winding pitches of the armor 2 around the section including the damaged part 7 of the armor 2 of this armored submarine cable 1, whereby a protective armor 9 is made around the section of the armor 2 in the section including the damaged part 7 so as to repair it.

摘要： PROBLEM TO BE SOLVED: To provide a doubly armored submarine cable which can prevent generation of kinks, even if a structure is employed where an inner armor body is formed with FRP wires and an outer armor body is formed with iron wires. SOLUTION: The outer periphery of a cable body 2 is doubly shielded with an inner armor body 3 and an outer armor body 4. The inner armor body 3 is formed with FRP wires 16, and the outer armor body 4 is formed with iron wires 19. The inner armor body 3 formed of the FRP wires 16 and the cable body 2 are twisted in the same direction. The outer armor body 4 formed with the iron wires 19 is twisted in the opposite direction to the winding direction of the inner armor body 3 and the cable body 2.

摘要： PURPOSE:To facilitate the dissociation of a single crystal from a crucible and a liquid sealant with a device for executing a TKM method using the liquid sealant by providing a means for removing the liquid sealant from the crucible after the solidification of a raw material melt. CONSTITUTION:Polycrystalline raw materials of polycrystal GaAs and B2O3 (liquid sealant) are put into the crucible 14 and a seed crystal 1 is attached to a pulling-up shaft 4. The inside of a high-pressure vessel 13 is evacuated to a vacuum. Ar which is an inert gas is introduced and the pressure and temp. thereof are increased to melt the raw materials. The seed crystal 1 is then brought into contact with the raw material melt 2 and the temp of heaters 5, 6 is controlled to execute seeding. While the temp. in a melt zone and a low-temp. zone is controlled to 1250 deg.C to 900 deg.C, the seed crystal 1 and the crucible 14 are moved upward and the melt 2 is fully solidified to the single crystal. The crucible 14 is moved toward a liquid sealant container 9 which is made of quartz and is provided above the heater 5. The container 9 is heated to the temp. higher than the temp. around the crucible 14 by a heater 10. The pressure in the container 9 drops and the sealant 3 is sucked into the container 9 when the nozzle at the front end of the container 9 is brought into contact with the sealant 3 and the temp. of the heater 10 is lowered.
