  • Patent number: 8334024
    Abstract: An apparatus for single-sided bilayer formation includes a first fluid chamber including a sidewall and a second fluid chamber extending through the sidewall. A barrier wall, having at least a portion defining a hydrophobicity or hydrophilicity surface property, separates the first and second fluid chambers and includes a nanopore therein across which a planar lipid bilayer (PLB) is formed. In use, an electrolyte is added to the first and second fluid chambers and a lipid/organic solvent mixture is added to the first fluid chamber to form a lipid/organic solvent layer. The electrolyte level within the first fluid chamber is adjusted such that the lipid layer is raised above the barrier wall and a PLB is formed through single-sided spontaneous formation from the first fluid chamber across the nanopore.

    Abstract: The present invention provides a chromium-free surface treating method capable of treating a surface of a metallic member having a surface of zinc or zinc alloy so as to provide good blackness and rust inhibitive performance, and an aqueous solution for chemical conversion coating that can be applied to the treatment method. The aqueous solution contains neither trivalent or hexavalent chromium ion, and contains 5-20 g of phosphate ions per liter, 0.1-3 g of divalent iron ions per liter, 1-10 g of divalent manganese ions per liter, and 1-3 g of nitrate ions per liter. The aqueous solution has a pH of 1-3. A black coating film of Fe3O4 is formed by immersing the metallic member in the aqueous solution, then a conversion coating film of cerium oxide is formed thereon, and then a siliceous coating film is formed thereon.

  • Patent number: 7964069
    Abstract: A device for galvanic coating of a piston has a pot-shaped interior for accommodating the piston and an electrolyte fluid, a holder device for fixing the piston in place, a cover that is structured like a shutter and leaves only the surfaces of the piston that are to be coated uncovered, a first electrical contact that is connected with an anode and with the plus pole of a direct voltage source, and a second electrical contact that connects the piston with the minus pole of a direct voltage source. The piston can be simply and quickly attached to the holder device, since the holder device is in plate shape, and has an oblong centering device, the length of which corresponds to the radial inside diameter of the piston to be coated so that the piston can be pushed onto the centering device by way of its underside.

  • Patent number: 7914851
    Abstract: A spangle-free, hot-dip galvanized steel sheet, and a method and device for manufacturing the same. The hot-dip galvanized steel sheet is characterized in that a solidified zinc crystal of hot-dip galvanized layer has an average crystalline texture particle diameter of 10 to 88 ?m and there is no solidification traces of dendrites upon observing under a microscope at a magnification of 100×. The method comprises dipping a steel sheet in a bath of a zinc-coating solution containing 0.13 to 0.3% by weight of aluminum; air-wiping the steel sheet to remove an excess of the coating solution; spraying water or an aqueous solution on the air-wiped steel sheet, using a steel sheet temperature in the range of a hot-dip galvanization temperature to 419 ° C. as a spray initiation temperature and using a steel sheet temperature in the range of 417 ° C. to 415 ° C.

  • Patent number: 7879772
    Abstract: Particles each of which consists of an inorganic polyvalent metal compound as a nucleus and a coating of a metallic soap of the polyvalent metal coating the nucleus (coated particles); products and preparation processes using the particles; a lubricating coating forming agent wherein particles each of which consists of a polyvalent metal salt of phosphoric acid as a nucleus and a coating of a metallic soap of the polyvalent metal coating the surface of the nucleus are suspended in an aqueous solution of a water soluble inorganic salt and/or a water soluble organic acid salt; and a lubricating coating. The coated particles are novel particles which can be used as an ingredient of coating-type lubricating coating; are excellent in seizure resistance; can inhibit wear of tools at the time of plastic working since the friction coefficient of the surface of the particles is low; and are slow to cause pollution of working oils.
