Title: Ecr plasma work
Inventor: OBA KAZUO
IPC: H05H1/46
Filed: 1992-10-09
Abstract: PURPOSE:To enable highly accurate etching and coating work in ECR plasma work by focusing an ion current while giving pulse voltage to a rotating magnetic field, and giving next the pulse voltage also to a deflecting plate. CONSTITUTION:Pulse voltage is given to a rotating magnetic field of a rotating magnetic field generator having a focusing electromagnetic lens 4, and an ion current is focused, and next, the pulse voltage is given also to a deflecting plate electrode 3, and acceleration voltage is also impressed in plasma. The rotating magnetic field is generated by impressing the pulse voltage upon respective coil terminals after coils are wound separately round iron cores. Thereby, since the ion current is focused in the central part of a passing hole, ion scattering is reduced, so that highly accurate work becomes possible. The deflecting plate electrode 3 increases further speed of an ion beam going toward a material 1 to be worked from the center of the focusing lens 4, and increases etching work speed. Coating speed is also increased, and an effect of heightening working accuracy can be obtained by squeezing the ion beam.

Title: Stud welding method
Inventor: SEKIGUCHI TAKAMASA
IPC: B23K11/00
Filed: 1993-10-05
Abstract: PURPOSE:To easily weld a part to be welded on the metal sheet surface of thin thickness base metal by welding as non metal sheet is integrated on the rear face of welding surface of base metal sheet at executing stud welding of a part to be welded a bolt, etc., on the surface of base metal sheet. CONSTITUTION:Welding is executed as non metal sheet is integrated on the rear surface of welding surface of base metal sheet. Non metal sheet prevents the molten pool formed the surface of metal sheet from falling off before a part to be welded is studded. Non metal sheet is of various plastic sheet, ceramic sheet, non organic sheet. Plastic sheet is most preferable for forming flat smooth surface. The effect of non metal sheet is significant by integrating molten pond in closely contact with non metal sheet surface not so as to leak the molten pool from the rear surface of metal sheet. By this method, a part to be welded of bolt, etc., is welded on the metal sheet of thin thickness welding base metal.

Title: Paper accumulator
Inventor: SAKURAI TOSHIO
IPC: B65H31/20
Filed: 1986-11-17
Abstract: PURPOSE:To prevent jamming, inversion, breaking, etc. of paper, by arranging a base section for guiding the tip portion of paper advancably/retreatably on a mounting table between a feed roller and the mounting table, thereby making the length of a paper accumulation area in the carrying direction variable. CONSTITUTION:When papers of intermediate size are accumulated by means of a paper accumulator 1, plates 8, 9 are moved downward while resisting against a spring 10, then only the plate 8 is rotated and projected from a base section 4 so as to form a paper accumulation area 7b on a paper mounting table 3 between a stopper 5. Consequently, a paper 6b being carried through a pair of feed rollers 2 slides over the base section 4 and guided by the plate 8 onto the mounting table 3, thereby the front end thereof is contacted against the stopper 5 by means of an energizing roller 11 while the rear end thereof approaches closely to the plate 8 so as to accumulate the paper sequentially at a position lower than the upper face thereof. In case of a large size paper, both plates 8, 9 contain the paper while in case of small size paper, the plate 9 is projected. Consequently, jamming, inversion, breaking, etc., of paper can be prevented when accumulating various size of papers.

Title: Manufacture of high strength aluminum or aluminum alloy bar
Inventor: ANADA HIROSHI
IPC: B21C37/04
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a high strength, high hardness aluminum or its alloy easily without using an expensive drawing die by applying a twisting processing to an aluminum or aluminum alloy bar in one direction and after then twisting it back to a reverse direction. SOLUTION: An aluminum or aluminum alloy bar is prepared as a raw material. This bar may be an extrusion bar, a continuous cast rolling bar, a drawing bar and, also, any one thereof for which annealing or stability treat heating is applied. As an aluminum, an industrial pure aluminum, for example, 1060, 1050 and the like may be used. When a higher strength is required, it is preferable that an Al-Mg system alloy is selected out of the aluminum alloy. For these bars, a twisting processing is applied first in one direction. Then, the same number of twisting back is applied in a reverse direction. Thus, the status of a surface roughness and a metal flow are restored to almost the same level as before the twisting in a manner that it becomes hardly distinguishable from appearance.

In addition, the resin skin layer is of a matter whose friction coefficient is low and even if a thin film layer of TiN is formed through, for example, sputtering, a similar effect become effective. Since the skin layer, whose friction coefficient is low, is formed on the inside of the cavity, high release properties are obtained. Therefore, elimination of a restriction on a design following to a reduction of a draft of a molded product or shortening in a molding cycle becomes possible.
