Title: Photoelectron image reduced projection type electron beam exposure method
Inventor: YASUDA HIROSHI
IPC: H01L21/027
Filed: 1983-09-21
Abstract: PURPOSE:To reduce the adverse effect of a proximity effect by forming a reticle with a pattern consisting of a photoelectron generating film brought ot a porous state so that the mean electron-beam generating efficiency of the pattern is minimized with the increase of pattern size and executing reduced exposure. CONSTITUTION:A large number of holes (circular holes from which gold is removed) are formed to a large pattern 14 for a gold thin-film to shape a porous film, and a small pattern 13 is left as it is a conventional compact film. The hole diameter is formed in size such as approximately 0.2mumphi one, and formed in size in an extent that the hole is not made sure when a reticle with these patterns is reduction-projected. Accordingly, a proximity effect is reduced because the number of photoelctrons discharged per the unit area of the large pattern 14 is made smaller than that of the small pattern 13. The gold thin- film having the porous film quality can be formed by adjusting a sputtering method, through which gold is applied, or etching (containing lift-off) the film after coating.

Abstract: PURPOSE:To detect an angle accurately, by exciting two three-phase winding series circuits different in the array sequence with the same voltage. CONSTITUTION:In a three-phase variable reluctance type resolver 20, a series circuit 21 of three-phase windings (a), (b) and (c) is connected in parallel to a series circuit 22 of the windings (b), (c) and (a) arranged in the array sequence of being shifted by one phase.

Title: Upset welding method
Inventor: NAKANE YUTAKA
IPC: B23K11/25
Filed: 1982-10-05
Abstract: PURPOSE:To perform titled welding without any welding defect by determining the position of a moving base at the point of the time when the initial movement of the moving base right after starting of conduction of electricity to objects to be welded ceases as a reference point and changing over a heating stage to an upsetting stage at the point of the time when the moving base moves by a set extent from the reference point. CONSTITUTION:The displacement of a moving base is shown by a curve I , the change in welding current by a curve II and the change in a welding force by a curve III respectively. The moving base that clamps objects to be welded starts moving from a position P0 and stops in a position P1 where the butt end faces of the objects are pressed to each other. Conduction of welding current is started in a position P2 and the moving base moves to a position P3 where the objects come into uniform contact with each other. The position where the initial movement of the moving base ceases is determined as a reference point Ps0. The position Ps1 of the moving base where it moves by a preset moving extent l1 from the point Ps0 is determined as the point of the time when a heating stage is changed over to an upsetting stage. The welding current is interrupted in a position Ps2 and the moving base is stopped by bringing said base into contact with a stopper in a position Ps3.
