  • Publication number: 20030008169
    Abstract: Disclosed is a composite sliding material having a steel plate and a sintered copper alloy layer which is bonded to the steel plate. The copper alloy contains, 1.5 to 15 mass % Sn, 1.5 to 15 mass % Bi, 1.5 to 20 volume % of a solid lubricant, and balance of Cu and incidental impurities. The volume ratio of Bi to the solid lubricant is in a range of 0.5 to 2.0. Bi and the solid lubricant improves the copper alloy in sintering property, since Bi melts when sintering because of a low melting point resulting in improved sintering property, and the solid lubricant ensures good anti-seizure property, and deterioration of mechanical strength is prevented by virtue of a phenomenon that the solid lubricant is entrained in Bi.

  • Publication number: 20030008177
    Abstract: In a thin film magnetic disk, a crystalline CrNi pre-seed layer is sputtered onto a substrate such as glass, followed by a RuAl seed layer. The CrNi pre-seed layer reduces grain size and its distribution, and improves in-plane crystallographic orientation, coercivity (Hc) and SNR. In a preferred embodiment the RuAl seed layer is followed by a Cr alloy underlayer. In a preferred embodiment the Cr alloy underlayer is followed by an onset layer and a magnetic layer, or by two or more magnetic layers antiferromagnetically coupled through one or more spacer layers. The crystalline CrNi pre-seed layer allows use of a thinner RuAl seed layer which results in smaller overall grain size, as well as a reduction in manufacturing cost due to relatively high cost of ruthenium. The CrNi pre-seed layer also allows use of a thinner Cr alloy underlayer which also contributes to reduce overall grain size.

  • Publication number: 20030008178
    Abstract: A thin film magnetic media structure with a pre-seed layer of CrTi is disclosed. The CrTi pre-seed layer presents an amorphous or nanocrystalline structure. The preferred seed layer is RuAl for use with the CrTi pre-seed layer. The use of the CrTi/RuAl bilayer structure provides superior adhesion to the substrate and resistance to scratching, as well as, excellent coercivity and signal-to-noise ratio (SNR) and reduced cost over the prior art. One embodiment of the invention sputter-deposits a CrTi pre-seed layer and a RuAl seed layer followed by at least one underlayer and at least one magnetic layer on a circumferentially polished substrate structure to achieve an Mrt orientation ratio greater than one. Two methods according to the invention allow the Mrt orientation ratio of the disk to be adjusted or maximized by varying the thickness of the RuAl seed layer and/or altering the atomic percentage of titanium in the pre-seed layer.

    Abstract: A new capping multilayer structure for EUV-reflective Mo/Si multilayers consists of two layers: A top layer that protects the multilayer structure from the environment and a bottom layer that acts as a diffusion barrier between the top layer and the structure beneath. One embodiment combines a first layer of Ru with a second layer of B4C. Another embodiment combines a first layer of Ru with a second layer of Mo. These embodiments have the additional advantage that the reflectivity is also enhanced. Ru has the best oxidation resistance of all materials investigated so far. B4C is an excellent barrier against silicide formation while the silicide layer formed at the Si boundary is well controlled.

  • Publication number: 20030008183
    Abstract: The trend in personal and light commercial transportation vehicle choices is heading toward electric or fuel cell vehicles capable of zero emission. Their demand for electricity to re-charge batteries or hydrogen to operate fuel cells can best be met by variable onsite production of electricity and hydrogen from conventional transportation fuel by an on-site energy supply system employing a conversion device. This approach can result in minimum changes in the present day infrastructure of the automobile and truck service station industry and can avoid any disturbances to the normal operation of the electric power industry. The onsite hydrogen/electricity hybrid conversion device is a reformer and/or a fuel cell. The output of the system can be varied to either meet the demand of hydrogen fuel for fuel cell vehicles or to provide electricity for charging batteries used on the electrical vehicles.

The container may have a generally flat and thin profile, formed as a pouch or envelope with substantially planar top and bottom faces of flexible film material, such that the container holding the reservoir structure and filled with liquid fuel can be bent or shaped.

  • Publication number: 20030008194
    Abstract: A manifold for a fuel cell system comprises a plurality of first ports for connecting to fuel cell peripherals; a plurality of ports for connecting to a fuel cell stack; and a plurality of fluid passages within the manifold in communication with the said plurality of ports connecting to the fuel cell peripherals and with the first and second ports for providing, communication of fluids between the fuel cell stack and fuel cell peripherals. The manifold provides a higher degree of system integration, considerably reduced piping, fittings and associated hardware and hence generally reduces the size and weight of the fuel cell system. Thermal-fluid related system losses are also minimized.

  • Publication number: 20030008199
    Abstract: An electrocatalyst based on a highly electroconducting polymer and a transition metal, in which transition metal atoms are covalently bonded to heteroatoms of the backbone monomers of the polymer. The covalently bonded transition metal atoms are nucleation sites for catalytically active transition metal particles. The complex is prepared by complexing a highly electroconducting polymer with transition metal coordination ions and then reducing the transition metal ions to neutral atoms. An electrode for a fuel cell is made by impregnating an electrically conducting sheet with the catalytic complex and drying the impregnated sheet. A fuel cell with a liquid anolyte uses the electrode as its cathode. The anolyte includes an aqueous solution of conjugate polybasic acids buffer, such as H3PO4—NaH2PO4—Na2HPO4, and an alcohol such as methanol as a reductant.

    Abstract: A method for recycling a battery pack is provided that enables a degraded battery pack to be replaced at a low cost while maintaining the advantages of a conventional sealed-type nickel-metal hydride secondary battery as being free from maintenance or leak of an electrolyte. The battery pack accommodates a battery module having a plurality of cells, which are a sealed-type nickel-metal hydride secondary battery, combined with each other. When the battery pack is judged as being degraded in a market, the battery pack is collected from the market as a battery to be replaced; a cell or battery module judged as being degraded is renewed by adding an electrolyte thereto; the battery module is installed in the battery pack again; and the battery pack is supplied as a replacement battery.
