Title: Vane pump
Inventor: MASUDA KOUSAKU
IPC: F04C2/344
Filed: 1983-03-29
Abstract: PURPOSE:To improve resistance to abrasion and lubricating property and reduce cost by a method wherein a cam ring is formed by an outer peripheral member, having a center hole showing a configuration corresponding to the surface of a cam, and a belt-like member, fitted into the center hole and forming the surface of the cam. CONSTITUTION:The cam ring 7, having a cam surface 6 to which the tip end of a vane 4 at the side of a rotor 5 is inscribed, is formed by the outer peripheral member 20, having the center hole 20a showing the shape of an ellipse substantially, and the belt-like member 21, fitted into the center hole 20a and forming the cam surface 6. In this case, the cam surface 6, for which resistance to abrasion, lubricating property and the like are requested since the tip end of the vane 4 of the rotor 5 contacts therewith and slides thereon at all times, is formed by the belt-like member 21 capable of being formed simply and properly. The outer peripheral member 20 may be made of a comparatively low class material and formed simply without applying finishing machining or the like. According to this method, the manufacturing cost of the cam ring 7 may be reduced remarkably.

Title: Protecting method for surface of metallic sheet for deep drawing work
Inventor: NAKAO KIYOSHI
IPC: B21D22/20
Filed: 1980-04-21
Abstract: PURPOSE: To firmly adsorb the adhesive film to the metallic sheet for preventing the release of  adhesive film from the metallic sheet during the drawing work, and to protect the metallic sheet,  by sticking an adhesive film prepared by copolymerizing acrylic ester with a limited mol% of  acidic group monomer upon the metallic sheet and by applying the humidification treatment.   
     CONSTITUTION: A mixture of one kind or ≥2 kinds of acrylic acid, methacrylic acid and itaconic  acid functioning as a monomer having unsaturated ethylenic bond and acidic group is coplymerized together with acrylic ester such as ethylacrylate and butylacrylate, which functions as the  main component, at 1W10mol% to total components. This copolymer solution is applied to the  film and is dried up to finish the adhesive film which then stuck to the surface of metallic sheet  that is thereupon subjected to the humidification treatment. Thereby the water molecules diffused  in the adhesives approach the acidic group which is thereupon partly electrolytically dissociated  and is adsorbed by the metallic sheet, so that this metallic sheet can be subjected to the deep  drawing work without causing release of the adhesive film during the work proceeds. The reason  of limiting the mol% monomer is because the purpose can not be achieved by ≤1mol% and the  copolymerization reaction does not smoothly proceed by ≥10mol%.
