Title: Corrosion preventive treatment of aluminum coated steel wire
Inventor: MAEJIMA SEIJIYU
IPC: C23C22/66
Filed: 1980-12-05
Abstract: PURPOSE:To improve the corrosion resistance of a coating layer and prevent the formation of red rust in exposed parts by treating an Al coated steel wire in heated water of pH of a specific range. CONSTITUTION:An Al coated steel wire is subjected to a boiling treatment in heating water controlled to 8-10pH. Amines, alcohol amine, amides, ammonia and the like are used for this. Thereby, a boemite film is formed on the surface of the coating layer, and the corrosion resistance is considerably improved. The reason for limiting the pH here lies in that below 8pH it is undersirable in terms of passivation effect upon the exposed parts of the steel core. Above pH 10, the dissolution of Al takes place excessively on account of alkalinity simultaneously with boemite film formation, and this is not advantageous in the formation of the boemite film. In this treatment, the exposed parts of the steel core are passive, and are formed with lower oxide such as Fe(OH)2 and FeO, and since these are in a boiling state, they are converted to Fe2O3 of good corrosion resistance and adhesive strength, thereby preventing red rust.

Filed: 1989-06-30
Abstract: PURPOSE:To control mutual interference by making a distance between a central shielding member which partitions between a transfer electrifying part and a separation electrifying part and a transfer electrode, and also the distance between the central shielding member and a separation electrode respectively shorter than the height of the central shielding member. CONSTITUTION:The distances r2 and s2 between the central shielding member 403 which partitions between the transfer electrifying part and the separation electrifying part and the transfer electrode 91 and the separation electrode 92 are respectively and substantially made shorter than the height C of the central shielding member 403. The transfer electrode 91 is positioned so as to be offset to the side of a transfer outer shielding member 501 and the separation electrode 92 is positioned so as to be offset to the side of a separation outer shielding member 502, the electrodes 91 and 92 are positioned so as to be offset to the side of insulated shielding members. Thus, the distribution of corona discharging is offset to the side of a ground shielding member and the interference area becomes small, so that the optimum performance of the transfer and the separation is obtained.

Title: Preparation of grooved wadding material
Inventor: MORIOKA MASAYUKI
IPC: D06N7/00
Filed: 1985-08-02
Abstract: PURPOSE:To obtain a grooved wadding material having volume feeding, by grooving the urethane foam adhered to a face sheet to form not only two almost perfectly cut-out parts between unprocessed parts but also a part cut out so as to leave a part between said parts and drawing two parts near to each other to adhere a lining sheet and the part cut out so as to leave a part. CONSTITUTION:Grooving processing is applied to the urethane foam part 2 of a sheet having a two-layered structure by a knife or a rubstone so as to leave a reguired part. Grooving is performed so that two almost perfectly cut- out parts 4 are generated between unprocessed parts 3 and a part 5 cut out so as to leave a part is generated between two almost perfectly cut-out parts 4. The almost perfectly cutting-out grooving width (a) is set to the difference between the thickness (b) of the almost perfectly cut-out part and the thickness (c) of the part cut out so as to leave a part. The face sheet of thus obtained groove sheet is drawn near to form a groove in the side of the face sheet. Because the almost perfectly cutting-out grooving width (a) is set as mentioned above, the face sheet is made almost flush with the surface of urethane form 2 by drawing-near and a lining sheet 6 is adhered to this flattened surface.
