    • PROBLEM TO BE SOLVED: To provide a joining method in which there is no leakage of fluid between a metal tube and other members.SOLUTION: A motor 8 rotates a metallic glass tube 1 and stainless steel tubes 2a and 2b attached to a jig 4 through a motor rotary shaft 9, a flange 6b, and a flange 6a. 12 is a nickel anode. The metallic glass tube 1, the stainless steel tube 2a and 2b attached to the jig 4 are put in a nickel electroforming tank 13 that puts in an electrolytic solution 11 for nickel electroforming. They are rotated in the electrolytic solution 11 for the nickel electroforming by motor 8, and an electroforming layer 14 is formed. In this case, the electrolytic solution 11 for the nickel electroforming in the nickel electroforming tank 13 is warmed to about 45°C. When the nickel electroforming layer 14 reaches a prescribed thickness, the switches of a power source 10 and the motor are turned off. The flanges 6a and 6b are separated, the jig 4 or the like is taken out from the nickel electroforming tank 13, the connected metallic glass tube 1 and stainless steel tubes 2a, and 2b are taken out of the jig 4 made of a resin, and resist is removed by a solvent or the like afterwards.
    • 要解决的问题:提供在金属管和其它部件之间不存在流体泄漏的接合方法。 解决方案:马达8通过马达旋转轴9,凸缘6b和凸缘6a旋转金属玻璃管1和附接到夹具4的不锈钢管2a和2b。 12是镍阳极。 将金属玻璃管1,安装在夹具4上的不锈钢管2a和2b放入镍电铸槽13中,镍电铸槽13放入用于镍电铸的电解液11中。 它们通过电动机8在用于镍电铸的电解液11中旋转,形成电铸层14。 在这种情况下,将用于镍电铸槽13中的镍电铸的电解液11加热至约45℃。 当镍电铸层14达到规定厚度时,电源10和电动机的开关被断开。 凸缘6a和6b被分离,夹具4等从镍电铸槽13中取出,连接的金属玻璃管1和不锈钢管2a和2b从由树脂制成的夹具4中取出, 然后用溶剂等去除抗蚀剂。 版权所有(C)2013,JPO&INPIT
