Title: Tape guide device
Inventor: KAWAGUCHI SABURO
IPC: G11B15/665
Filed: 1985-12-28
Abstract: PURPOSE:To prevent a tape from coming into contact with a tape guide periphery by controlling the drive of a pump supplying air to a tape guide in accordance with tape tension at a tape winding side. CONSTITUTION:A tension detection means 26 installed on the tape winding side T detects the tension of the tape 11 at the winding side T. The tension appears as the changing amount of a potentiometer 30 when it increases, and is transmitted to a motor drive circuit 32. It boosts the drive voltage of a power source 33 supplied to a motor 25 to increase the drive of a pump 24, whereby the pressure and flow of the air supplied to tape guides 5 and 6 are increased. Thus an air layer between the tape 11 and the peripheries 5a and 6a of the tape guides 5 and 6 can be maintained, whereby the contact of the tape 11 with the peripheries 5a and 6a can be prevented.

Title: Method for degreasing can body made of aluminum
Inventor: ISHIKAWA HIROYASU
IPC: C23G1/12
Filed: 1990-11-05
Abstract: PURPOSE:To prevent deterioration in the physical properties of a chemical conversion coating caused by the contamination with Cu atoms and to improve corrosion resistance by removing Cu, eluted from a can body material into a degreasing solution, by the prescribed method and regulating Cu ion concentration to a specific value in the course of degreasing an Al can body. CONSTITUTION:In the course of degreasing an Al can body, Cu<2+> ion concentration is kept at <=3ppm, e.g. by adding a complexing agent to an acidic degreasing solution or adding an oxysulfur compound of 2-4 oxidation number of S to precipitate Cu<2+> ions. By this method, the deposition of Cu onto the Al can body can be remarkably reduced and deterioration in the physical properties of a chemical conversion coating caused by the contamination with Cu atoms in the chemical conversion treatment stage after degreasing can be prevented. As a result, the corrosion resistance of the can body made of Al can be remarkably improved.
