Patent number: 5336425Abstract: The stability of an acidic liquid cleaner for aluminum comprising mineral acid, oxidant, polyvalent metal ions, and surfactant is substantially improved by the presence in the cleaner of from 0.05 to 5 g/L of a component selected from the group of glycols containing from 2 to 10 carbon atoms per molecule and mixtures of such glycols. The effectiveness of the cleaner for primary cleaning and de-smutting of aluminum and its alloys is not impaired and may even be improved by the addition of the glycol component.Type: GrantFiled: December 21, 1992Date of Patent: August 9, 1994Assignee: Henkel CorporationInventors: Tomoyuki Aoki, Yasuo Iino, Yoji Ono, Shinichiro Asai

Patent number: 4980076Abstract: Problems with previously known aqueous acidic rinsing solutions for aluminum after shaping while using surface lubricants are avoided by use of a solution which contains water and (A) orthophosphoric acid in an amount to give a stoichiometric equivalent of 3.0 to 50 g/L as PO.sub.4.sup.-3, (B) an aluminum ion sequestrant component in an amount of 0.01 to 10.0 g/L; and (C) 20 to 170 ppm of ferric ion. The ferric ions act to inhibit corrosion of the stainless steel process equipment. Preferably the solution also contains 0.1 to 1.0 g/L of H.sub.2 O.sub.2, NO.sub.2.sup.-1 ions, or a mixture thereof to reoxidize ferrous ions formed by reduction of ferric ions during use of the solution and thus maintain the concentration of ferric ions above 20 ppm at all times. The solution may also contain surfactant and up to 10 g/L of dissolved aluminum ions.Type: GrantFiled: September 6, 1989Date of Patent: December 25, 1990Assignee: Nihon Parkerizing Co., Ltd.Inventors: Shigeo Tanaka, Tomoyuki Aoki, Yasuo Iino, Yoji Ono

Patent number: 4212040Abstract: A tape recorder is disclosed in which the movement of the pinch roller toward and away from the capstan, the movement of the take-up roller toward and away from the take-up reel mount and the movement of the brake plate toward and away from the take-up and supply reel mounts are performed by a single control board having three control sections. The movement of the control board is associated with that of the head base plate carrying a magnetic head and movable between a stop position and a playback position. When the head base plate moves to the playback position, the control board moves together with the head base plate by the elasticity of the spring member tensioned therebetween, whereby the three types of movements make possible the desired playback state. In response to an external operation for a pause, the control board alone is moved to the stop position, thus turning the three types of movements into a pause mode.Type: GrantFiled: July 10, 1978Date of Patent: July 8, 1980Assignee: Hitachi, Ltd.Inventors: Masashi Yoshida, Yasuo Iino
