PROBLEM TO BE SOLVED: To reduce the possibility of fracture of a pipe used for evacuation and a seal, when at least two stacked metal components are joined by diffusion bonding. SOLUTION: Edges of metal components 30, 36 are sealed each other, except for an aperture 49 where a connector 51 having a pipe 50 is connected. The connector 51 has a first end 52 and a second end 53. The first end 52 has a smaller diameter than the second end 53 and a bore 54 extends through the connector 51 from the first end 52 to the second end 53. The second end 53 of the connector 51 is joined to a stack. The pipe 50 is joined to the first end 52 of the connector 51. The interior of the sealed assembly is evacuated via the pipe 50 and the pipe is sealed. Heat and pressure for diffusion bonding are applied to the metal components 30, 36 so as to form an integral structure. The connector 51 reduces the possibility of fracture of the pipe 50 and/or seal 57 during diffusion bonding. COPYRIGHT: (C)2005,JPO&NCIPI |
