摘要： PURPOSE:To allow a solder to flow smoothly and concentratedly to a predetermined brazing portion by providing solder flowing grooves in the vicinities of end sides of solder placing grooves, and also providing a plurality of small slits communicating with the brazing portion in solder placing grooves. CONSTITUTION:In a pipe shaped joint 10 for use in brazing, solder placing grooves 4 are formed at the upper end portion and its lower end portion. Solders having suitable sizes are applied to both grooves 4. Solder flowing grooves 7 are formed at the upper end portion side and the lower end portion side in the vicinities of both solder placing grooves 4. Further, a plurality of small slits 8 extending on the central side in communication with solder placing grooves 4, are formed on both solder placing grooves 4. In a case where a damaged portions has been formed on the heat transfer tubes, a small-size reinforced pipe which is a joint 10 for use in brazing is inserted therein, and the damaged portion is brazed by high-frequency heating to coat and repair the damaged portion with solders. Upon this occasion, the solder flowing grooves 7 prevent the solders from unnecessarily diffusing and the slits 8 allow solders to easily flow toward the brazing portion.

摘要： PURPOSE:To prevent a molten brazing filler metal from staying in a brazing filler metal reservoir, and to expand a ratio by which said metal expands to a brazing gap, by covering at least the bottom face of the brazing filler metal reservoir with a material whose wettability to the brazing filler metal is bad, and also, whose melting point is higher than that of the brazing filler metal. CONSTITUTION:As for the bottom face of a brazing filler metal reservoir part 3, alumina, titanium oxide, and zirconium oxide of the same material as that of a flow stopper 7 are used, or these film are formed by coating by their application or thermal spraying. A sleeve which has been treated ion this way is inserted into a pipe, 1, and a brazing filler metal is melted by executing its brazing heating. The molten brazing filler metal expands into a narrow brazing gap 5 by a surface tension. In this way, the brazing quality can be improved.

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 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 method and apparatus for joining different kinds of material, which can maintain high strength in joining portion composed mainly of a soft material, in a joining method of different kinds of metal using a friction stir joining.
SOLUTION: The joining method of different kinds of material comprises the steps of: butting together a hard metallic material plate 2 and a soft material plate 1 that is composed of different kinds of metallic material with lower hardness than the hard metallic plate 2; inserting a pin 12 of a rotary tool 10 in the soft material plate 1 at the butting point 5; rotating and moving a shoulder 11 and a pin 12 while pressing a plate surface by the shoulder 11 of the rotary tool; and joining the plates together through plastic fluidization of the soft material plate 1 caused by frictional heat attributed to rotation. At the butting point 5, a stepped part 3 where the thickness of the soft material plate 1 is larger than that of the hard material plate 2 is prepared to generate an aperture between the shoulder 11 and the hard material plate 2, so that the soft material 4 softened and fluidized due to rotation of the rotary tool 10 can penetrate into the aperture.
