  • Publication number: 20110033755
    Abstract: It has long been recognized that replacing the Li intercalated graphitic anode with a lithium foil can dramatically improve energy density due to the dramatically higher capacity of metallic lithium. However, lithium foil is not electrochemically stable in the presence of typical lithium ion battery electrolytes and thus a simple replacement of graphitic anodes with lithium foils is not possible. It was found that diblock or triblock polymers that provide both ionic conduction and structural support can be used as a stable passivating layer on a lithium foil. This passivation scheme results in improved manufacture processing for batteries that use Li electrodes and in improved safety for lithium batteries during use.

  • Patent number: 7220456
    Abstract: A process for the patterning of a desired substance on a surface includes: (i) charging a particle formation vessel with a compressed fluid; (ii) introducing into the particle formation vessel a first feed stream comprising a solvent and the desired substance dissolved therein and a second feed stream comprising the compressed fluid, wherein the desired substance is less soluble in the compressed fluid relative to its solubility in the solvent and the solvent is soluble in the compressed fluid, and wherein the first feed stream is dispersed in the compressed fluid, allowing extraction of the solvent into the compressed fluid and precipitation of particles of the desired substance; (iii) exhausting compressed fluid, solvent and the desired substance from the particle formation vessel at a rate substantially equal to a rate of addition of such components to the vessel in step (ii) through a restrictive passage to a lower pressure whereby the compressed fluid is transformed to a gaseous state, and wherein the re

  • Patent number: 7153585
    Abstract: The invention concerns to the use of a powder comprising 99.95 to 95% of at least one polyamide and 0.05 to 5% of at least one silane for coating metals. This powder may be prepared by simple dry blending of the constituents. The silane can also be added to the molten polyamide in a mixing device and the resulting product reduced to powder. The addition of silane makes it possible to significantly improve electrostatic application by preventing a substantial portion of the powder from falling off during the electrostatic discharge which follows application, while providing lasting adhesion between the coating and metal. Advantageously, the silane is chosen from aminopropyltriethoxysilane and aminopropyltrimethoxysilane. The invention also concerns a method of coating an object with a film resulting from melting a thin layer of the powder.

  • Patent number: 7083830
    Abstract: A process for the production of special effect base coat/clear coat two-layer coatings on substrates by application of a special effect base coat layer of a liquid special effect base coat onto the substrate in one or more successive spray passes, optional drying or curing of the special effect base coat layer, followed by application of a clear coat layer and curing of the clear coat layer, wherein, at least in the final spray pass, application of the special effect base coat proceeds by electrostatically-assisted high-speed rotary application using at least one high-speed rotary coating device comprising a high-speed rotary bell, wherein an electrode ring is rotatably positioned around the high-speed rotary bell and used for external electrostatic charging of the effect base coat spray mist and performs rotational movements about the common axis of rotation with the high-speed rotary bell.

  • Patent number: 7048972
    Abstract: After forming a primary powder bed (i.e., powder layer) at a toothed portion of an article, such as a gear or a spline shaft, by electrostatic powder coating process, the powder bed/layer is removed from crests of teeth in the toothed portion by a specified thickness by scraping it off while sucking up the scraped powder. Next, the electrostatic powder coating process is performed again to form a secondary powder bed/layer over the entire surface of the toothed portion. Then, the primary and secondary powder beds/layers are melted or fused by induction heating to thereby form a coating film of a substantially uniform thickness.

  • Patent number: 6926924
    Abstract: A metal-composite hose having a wall including an innermost metal layer and a resin layer surrounding it, in which the metal layer has at each end portion of the hose an inner surface covered with a resin layer, an elastic rubber layer, or both. A process for manufacturing a metal-composite hose includes: forming a metal layer; covering the metal layer with an elastic rubber layer, if required; and after masking a specific portion of the metal layer, forming a thermoplastic resin layer thereon by powder or spray coating. The hose is preferably a corrugated one. It has high fluid impermeability, flexibility and strength, as well as high metal-rust resistance and sealing property at both ends.

  • Patent number: 6896935
    Abstract: A method of forming a coating on an inner periphery of a tube with a cylindrical barrel, a mouth on one axial end of the barrel, and a shoulder located between the barrel and the mouth. The method involves holding the tube, and subsequently jetting powder into the tube from a spray gun, through a bottom side opening on the other axial end of said barrel. A first passage guides to the spray gun a first air stream together with the powder. A second passage feeds to the spray gun a second air stream with the powder. A third passage suction collects surplus powder through the tube mouth. A fourth passage suction collects surplus powder through the bottom side opening of the tube. At least one of the passages is subject to a feedback control such that flow rate and/or internal pressure therein are maintained at target levels.

  • Patent number: 6713134
    Abstract: There is provided an apparatus for spin-coating a semiconductor substrate, including (a) a rotary table rotatable in opposite directions, (b) a nozzle dropping coating material onto a semiconductor substrate lying on the rotary table, (c) an electrode having a ring-shaped cross-section and disposed around the rotary table, and (d) a power source applying a voltage to the electrode, the voltage having an electric polarity opposite to an electric polarity of the coating material. Coating material dropped onto the semiconductor substrate is attracted to an electric field generated by the electrode around the semiconductor substrate. Hence, the coating material is not concentrated around a center of the semiconductor substrate, but is facilitated to uniformly spread over the semiconductor substrate, ensuring formation of a coating layer having a uniform thickness.
