  • Patent number: 9206014
    Abstract: A plurality of relatively long wires having the same diameter are bundled together to obtain a bundle wire in a continuous wire bundling process. A wire bundling device includes a plurality of reels rotated by a rotating drive and wind a wire while a first end is engaged. A wire second-end pressing device collects and presses a second end of each of a plurality of wires having a predetermined length which is fed from a single spool and individually wound around each of a plurality of reels. The wires are withdrawn in a collected state from the reels by a withdrawing device between the plurality of reels and the wire second-end pressing device. The wire second-end press includes first and second pressing devices. The reels are rotated by an electric motor with a contact roller that rotates in contact with an outer circumference of the reel. The motor can be moved so that the contact roller selectively makes contact with the outer circumferences of the reels.

  • Patent number: 9067175
    Abstract: Disclosed are a method and an apparatus for removing methane from a gas which contains the methane at such a low concentration as not to be rendered into a combustible range with whatever ratio of air mixed therewith. In order to ensure satisfactory methane removal performance even in the coexistence of sulfur compound and in order also to provide stable methane removal performance for an extended period of time without performance deterioration even when the methane concentration varies significantly, the gas is fed to a heat exchanger for preheating and methane is exposed to an oxidation catalyst which oxidizes the methane through contact therewith. Then, the resultant gas is fed again to the heat exchanger for heat recovery through heat exchange with un-reacted gas. Further, the flow rate of gas to be treated is varied, according to a concentration of the methane contained in this treated gas.

  • Patent number: 8945246
    Abstract: An object of the present invention is to provide a method for producing a liquefied fuel oil using biomass as a feedstock, in which a relatively inexpensive liquefaction apparatus is used; a good balance is maintained between the liquefaction of water-insoluble lignin and the liquefaction of water-soluble cellulose to achieve a high yield of the liquefied fuel oil based on the biomass solids content; and the amount of ash derived from an alkali catalyst and the like is low. The method for producing a liquefied fuel oil using biomass as a feedstock is characterized by adding, to biomass comprising lignocellulose, a solvent comprising an organic solvent and having a moisture content adjusted to 10 to 25 wt %, including moisture contained in the biomass, and liquefying the biomass at a temperature of 250 to 350° C.

  • Patent number: 8430020
    Abstract: A piston allowing a lubrication layer of a resin coating with a low friction coefficient to be tightly adhered to a skirt portion of a piston for an internal combustion engine, with low friction, superior wear resistance, and superior anti-seizing properties and that can reduce wear of a cylinder inner wall even if the lubrication layer is peeled off or abraded, is provided. Metal or ceramic fine particles having an average particle diameter of 20 ?m to 400 ?m are injected with compressed air or compressed nitrogen as a mixture fluid onto the skirt portion of the piston, made of an aluminum alloy and produced by a method such as casting or forging, at an injection speed of 80 m/s or more or an injection pressure of 0.2 MPa or more to be collided with the skirt portion, thereby uniformly making a microstructure of a piston base material fine-grained in a depth range of 1 ?m to 15 ?m from a surface of the skirt portion and forming a modified layer with an activated surface.

  • Patent number: 7929517
    Abstract: A VoIP adapter module for a VoIP phone system switches the phone connection from a broadband connection to a wired connection when a power outage or a broadband disconnection is detected. The switch is accomplished by establishing a connection from a telephone connected to an RJ11 port on the module to a wired channel connected to a backup RJ11 port on the module. Detection for power outage is by comparing the device voltage with a reference voltage, and detection for broadband connection is by sending out a PING packet and waiting to see if a return packet is received.
