Filed: 1988-09-20
Abstract: PURPOSE:To obtain the lightness of weight further with excellent wear resistance by providing a metal molybdenum explosion bonding covered layer of specific thickness in the internal surface of a member molded in a cylinder shape by an aluminum alloy of specific composition. CONSTITUTION:Constitution of this cylinder 3 is such that an explosion bonding covered layer of 30 to 200mum thickness, consisting of metal molybdenum, is provided in internal surfaces of a member molded in a cylindrical shape by an aluminum alloy composed of 5 to 25% silicone, 0.3 to 5% copper, 0.3 to 3% magnesium and the rest of aluminum by the reference of weight as the essential component. Then, of these components, action of the silicone improves wear resistance and decreases a coefficient of linear expansion, and action of the copper improves wear resistance and high temperature strength. While action of the magnesium, similar to the copper, improves the wear resistance and the high temperature strength. And the molybdenum, forming the covered layer by explosion bonding, uses metal single substance molybdenum. Thus, the cylinder 3 for use of a compressor enables even its weight to be reduced with sufficient durability.

Title: Hydrophilic coating film and method for forming the same
Inventor: YAMAMURA NOBUHIRO
IPC: B05D5/00
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To make a hydrophilic coating film which is highly hydrophilic, stainproofing, and resistant to acid rain by forming a hydrophilic membrane on the surface of the coating film of the top layer. SOLUTION: When a melamine type coating film or an enamel type coating film is irradiated with ultraviolet rays in the presence of oxygen, the surface of the coating film reacts with oxygen to produce hydrophilic carboxyl, carbonyl, or hydroxyl groups so that a hydrophilic membrane is formed on the surface. For a hydrophilic coating film, the hydrophilic membrane is formed on the surface of the coating film of the top layer. Accordingly, the adhesion of lipophilic carbonaceous stains is checked. Since the surface of the coating film is hydrophilic, rain drops on the coating film are spread to flow and fall easily not only to reduce the absolute amount of rain drops left on the surface of the coating film but also to decrease the contact angle of the rain drop and to increase the contact area.  Therefore, even when acid components are concentrated by the evaporation of water from remaining rain drops, the absolute amount of the acid components per unit area is extremely low, preventing the deterioration of the coating film.
