摘要： PURPOSE:To improve a double pipe in property and quality by forming many parallel straight grooves on the outside of an inner pipe, laying the inner pipe in layers in an outer pipe through binder and contracting the outer pipe in diameter and clamping the outer pipe to the inner pipe. CONSTITUTION:Grooves 8 having a prescribed number and pitch are formed through machining, etc., on the outer surface of the inner pipe 2' of the grooves 8 are formed by welding square section bar material 7 having a prescribed number and pitch through brazing filler metal 9. Then, the inner pipe 2' is laid in layers in the outer pipe 1 of carbon steel, etc., on the outer pipe 1 is set an annular heating device 4, before and behind which are arranged annular devices 5 such as a showering device, etc. When the heating device 4 and the cooling device 5 are reciprocated in the axial direction of the outer pipe 1 all over the length, the outer pipe 1 is plasticized and strongly clamped to obtained a double pipe having many fine paths 8. Hereby, special properties and qualities of the double pipe such as heat exchanging properties, wire passing properties, etc., are improved.

摘要： PURPOSE:To improve the quality of a multiple bundled tube and to enlarge its length by bundling many fine diameter tubes through filler, arranging them in an outer pipe and traveling annular heating and annular coating alternately on the outer part of the outer pipe. CONSTITUTION:Many fine tubes 2' having prescribed size each are bundled previously and filled with brazing filler metal 7 as filler. Then, the outer pipe 1' is put on these bundled tubes to form a raw pipe 3' and a high frequency induction device, etc., at an annular heating device 4 and an annular cooling device 5 are arranged at prescribed sites of the outer pipe 1' under this state. When the heating device 4 and the cooling device 5 are traveled relatively in the axial direction, the heated outer pipe 1' is plasticized as its front and rear are constrained by the cooling device 5, clamped and rolled by a bending moment. Hereby, the heating device 4 and the cooling device 5 are reciprocated all over the length of the outer pipe 1 to obtain a multiple bundled tube strongly clamped through brazing filler metal 7. Therefore, the multiple bundled tube is improved in the quality.

摘要： PURPOSE:To continuously form a long-sized triplicate pipe of conductors by bonding a plurality of conductors between an inner pipe and an outer pipe through filler in an annular arrangement. CONSTITUTION:A plurality of conductors 6 having a prescribed fine diameter each are fixed tightly in a close state to each other and in an annular arrangement on the outer surface of the inner pipe 2 through brazing filler metal 7. The outer pipe 1 is put on the conductors and an annular heating device 4 such as a high frequency inductance heating device, etc., is set at a prescribed site of the outer pipe 1 and before and behind it or behind it at least are set annular cooling devices 5, 5 to perform showering. The annular heating device 4 and the annular cooling devices 5, 5 are moved relatively in the axial direction of the outer pipe 1, the brazing filler metal 7 is melted by the annular heating device 4, the diameter of the outer pipe 1 is expanded to the outer direction, the annular cooling before and behind the expanded part constrains the expansion of the diameter, the diameter is contracted to the inner pipe 1 through the conductors 6 and the inner pipe 2 is bonded tightly with the conductors 6. The brazing filler metal 7 is solidified by annular cooling, the conductors 6 are fixed to the inner pipe 2 and the outer pipe 1 to form a triplicate pipe of conductors 8.

摘要： PURPOSE:To prevent formation of an intermetallic compd. and to obtain satisfactory joint strength by cutting the surface layers of the soft metals at the end edges of hard metal joint furfaces to form fresh surfaces and bringing the joint surfaces and the fresh surfaces into press contact with each other thereby enabling joining at a low temp. CONSTITUTION:A jig 10 set therein with blocks 1, 7, 7 is introduced into a chamber and the atmosphere is maintained in a vacuum. While the respective blocks are kept heated, a hard metal block 1 is pressurized and depressed. The surface layers in the tapered parts 8, 8 of soft metal blocks 7, 7 are cut by the edges 5, 6 of the block 1 according to the descending of the block 1 by which fresh surfaces are formed on the blocks 7, 7 and are brought into tight contact with the surfaces in the tapered parts 2, 3 of the block 1. The pressurizing force is then decreased and after this state is maintained, the jig is cooled, by which the diffusion joining between both is completed.

摘要： PURPOSE: To make destruction of microdefects possible and to make segregation elements near grain boundary uniform by heating materials to be welded having microdefects in the inside at high temp. and applying high pressure.
CONSTITUTION: By heating materials to be welded in which microdefects such as cracks and pores etc. are generated in the inside of welding part at high temp., base materials are allowed to sufficiently cause plastic flow or creep behavior. Therewith, by pressing mechanically from each directions for uniaxial, biaxial, and triaxial or by applying high pressure such as hydrostatic pressure from all directions, the base materials are accelerated to behave plastic deformation. By holding enough time at such heated and pressured state and performing heat treating process or metallurgical reaction, the microdefects are desturcted. Then, by performing of unloading and cooling, the welding microdefects are extinguished. According this method, a disk of gas-turbine wheels and blades etc. are joined surely by meltwelding.

摘要翻译：目的：通过在高温下加热内部具有微缺陷的被焊接材料，可以破坏微观缺陷，并使晶界附近的分离元素均匀。并施加高压。构成：通过加热在高温下在焊接部件内部产生微裂纹，孔等的待焊接材料，使基材充分引起塑性流动或蠕变性能。因此，通过单向，双轴和三轴从各个方向机械地压制，或者通过施加来自各个方向的静水压力的高压，基材被加速以发生塑性变形。通过在这种加热和加压状态下保持足够的时间并进行热处理或冶金反应，微缺陷被破坏。然后，通过进行卸载和冷却，焊接微缺陷被熄灭。根据该方法，通过熔融焊接可靠地连接燃气轮机叶轮等的盘。

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a high pressure seal and ensure a long lifetime. SOLUTION: A high pressure seal 20 comprises a seal body 21 and a seal ring 22, and a first back-up ring 23 and a second back-up ring 24, so as to seal a high pressure fluid. The lip portion 21a is tapered, and the rubber seal ring 22 having a square cross section can be contacted therewith. The seal body 21 and the seal ring 22 have polygonal cross sections by combining the straight-line portions, which results in the easy processing of a lathe and the reduction in the manufacturing cost. The seal ring 22 can easily judge the twisting condition where it is not fitted with the lip portion 21a, which prevents the lifetime from being shortened. The first back-up ring and the second back-up ring 23, 24 deviate at the inner peripheral side or the outer peripheral side, so as to improve the adhesiveness for sealing the high pressure fluid.
