Title: Mold for injection molding
Inventor: KOYANAZU TOMOHIRO
IPC: B29C45/26
Filed: 1985-12-24
Abstract: PURPOSE:To easily obtain a highly accurate product by a method wherein a jetty is provided at the peripheral edge of the opening of each secondary sprue and in addition a chamber part of molten material is formed on the outer peripheral side of the jetty so as to once stock the inflowing molten material in the chamber part in order to flow the material through a gap, which is made between the tip of the jetty and a runner stripper plate, into the secondary sprue. CONSTITUTION:Molten material flowed through a sprue 8 in a runner 9 is obstructed by a jetty 13 and stocked in a chamber part. The molten material overflowed the jetty 13 flows through a gap S into a secondary sprue 12. The molten material stocked in the chamber part 14 flows in the secondary sprue 12 through any portion of the inner periphery of the jetty 13 of the peripheral edge of the opening of the secondary sprue 12 under nearly the same condition as one another so as to be filled in a cavity 10. Due to the time lag, which is produced in the molted material by the obstruction with the jetty 13 and the stocking in the chamber part 14, the difference between the times required for the molten material to reach the respective secondary sprues 12 is eliminated.

Between the transformer 10 and electrodes 50a, 50b, welding current is caused to flow through secondary cables 60a, 60b and beds 40a, 40b. In order to press a material to be welded by the electrodes 50a, 50b, one of electrodes is driven in the axial direction by a cylinder 30. Accordingly, at pressing the material to be welded between the electrodes 50a, 50b, the reaction force is transmitted to the transformer through the arms 20a, 20b. The transformer 10 has enough mechanical strength, overcoming the reaction force, it functions as a structural member/strength member of spot welding machine. Thus, the machine can execute robot welding, etc., of thick plate.

Title: Perpendicular magnetic recording tape
Inventor: KIMURA TAKAYUKI
IPC: G11B5/64
Filed: 1989-11-10
Abstract: PURPOSE:To improve the preservable stability of the tape without receiving the influence of the vinyl chloride binder of a back coating layer by forming the magnetic layer of the magnetic recording tape of a Co-Cr-W-C alloy film having excellent corrosion resistance. CONSTITUTION:The Co-Cr-W-C alloy film is formed as the magnetic layer on one surface of a base. This alloy film is formed by sputtering using an alloy target or composite target. On the other hand, the back coating layer is formed on the other surface by applying and drying of a nonmagnetic coating compd. mixed with a binder, nonmagnetic powder, hardener, and solvent. Since the alloy film forming the magnetic layer has the excellent corrosion resistance, the generation of the corrosion by the influence of the binder of the vinyl chloride system is obviated even if such binder is used for the back coating layer of the tape. The magnetic recording tape having the high preservable stability is thus obtd.
