Title: Material for joining fe-base alloy
Inventor: KAJIWARA RYOICHI
IPC: B23K20/00
Filed: 1986-12-01
Abstract: PURPOSE:To improve joining accuracy and to shorten joining time by incorporating B and Si elements into the alloy compsn. of a material to be joined thereby forming a material for joining. CONSTITUTION:The alloy prepd. by adding adequate ratios of B and Si elements to the Fe-base alloy compsn. as a material to be joined is deposited by evaporation on the joint surface of the material to be joined and the liquid phase diffusion joining is executed under the conditions of the prescribed temp. and time. Since both the elements B and Si exist in the joining material, the diffusion of Si is retarded from the diffusion of B and the extreme rise in the m.p. is suppressed. Since the joining material contains Si, the flowing property of a weld metal and the wettability with the Fe-base alloy is improved. The formation of a defect at the boundary face of an insert material is thus prevented. Since the thickness of the insert material is small, the accuracy of joining is improved and the time for joining is shortened.

Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent the particle contamination of a silicon wafer and the corrosion of a wafer conveying mechanism member by irradiating the wafer with electron beams in a vacuum. SOLUTION: A vacuum irradiation chamber 7 is set up in an X-ray shield chamber 10. Electron breams from an accelerating tube 8 of an electron beam generating part are introduced into the chamber 7 by scanning them in a magnetic field of a scanning coil 9. A load lock chamber 15 placed in the X-ray shield chamber 10 is connected to the vacuum irradiation chamber 7 through a gate valve 14. A conveying robot 16 to revolve and straightly move a fork which mounts silicon wafers 6 conveys the silicon wafer between the load lock chamber 15 and the vacuum irradiation chamber 7 and carries the silicon wafers 6 to an electron beam irradiation area. The wafers 6 are conveyed orthogonally to a scanning electron beam area.  A conveying robot 16 is placed in the vacuum irradiation chamber 7, and, as it is not installed in the X-ray shield chamber 10 made of lead, the precision in building-in, installation and conveyance of the wafers, is improved.
