Abstract: PURPOSE:To apply electron beam welding by giving a prescribed repeat motion to a convergence end of an electron beam, and also, melting a ring-like filler material, in an electron beam welding method of a conductor for electric conduction consisting of an Al material. CONSTITUTION:When an electron beam convergence end 9 is brought to circular motion 15 by using an emitting axis 12 as a rotation axis, a cross sectional shape of a fusion zone is improved roundly in a bottom part 11 of the fusion zone, and also, the fusion volume increases. As a result, it becomes a shape in which gas generated in the fusion bottom part 11 at the time welding comes out easily, no gas is left, and the generation of a crack in the fusion zone and a lack of penetration caused by blowoff of gas can be prevented. As for a filler material 13, the Si quantity is higher and the Mg quantity is lower than a base material. In order to improve a composition condition of the base material, the filler material 13 of the components is put into a fitting part 6 and inserted and held from both sides by an Al pipe 1 and terminal parts 3. In this state, when an electron beam 8 radiates, the filler material and the base material are melted simultaneously, and the composition of the fusion zone 5 is improved and it comes to be scarcely cracked. In such a way, electron beam welding can be applied, and that which has a high quality can be obtained.

Inventor: SAWA EIJI
IPC: G06F9/38
Filed: 1987-07-30
Abstract: PURPOSE:To carry out the arithmetic processing at a high speed by reading an arithmetic program out of a program memory based on a command given from a host computer and carrying out the arithmetic processing via a computing element with use of the data stored in a data memory. CONSTITUTION:When a command is received from a host computer 10, an arithmetic program is read out of a program memory 6. Then the arithmetic processing is carried out by a computing element 20 based on the data stored in a data memory 22. Thus the computer 10 is just required to produce a command of each arithmetic program to a status register 18. Then the computer 10 can perform the arithmetic processing via the element 20 in an arithmetic execution mode without participating in the element 20. Thus the arithmetic processing speed is increased.
