  • Patent number: 7549271
    Abstract: An airbag module for use in a motor vehicle is manufactured by first to third steps. In the first step, the airbag is folded into a predetermined configuration, and in the second step, an entire external surface of the airbag, in an initially folded condition obtained in the first step, is wrapped in a bag-shaped film forming member. The bag-shaped film forming member includes a plurality of resin layers formed in a layer-stack manner with regard to a film cross-sectional direction. In the third step, the initially folded airbag is housed in the airbag-housing member in a condition wherein the airbag has an airbag volume reduced to less than the airbag volume at a time of being initially folded, by a compression force applied to the bag-shaped film forming member.

  • Publication number: 20040146760
    Abstract: A hydrogen supply unit which generates electric power by use of a fuel cell and concurrently generates hydrogen, taking as its object the efficient generation of hydrogen from a source gas. The hydrogen supply unit 1 comprises a reformer 2 for reforming natural gas, a fuel cell 3 for generating electric power by use of the reformed gas from the reformer 2, and a purifier 4 for purifying hydrogen from the exhaust gas discharged from the fuel cell 3. The purifier 4 comprises a PEM 9 for conducting purification on the basis of the membrane separation method, and a PSA 11 for conducting purification by use of the pressure swing adsorption method. In the present invention, the reformed gas from the reformer 2 is used, without being subjected to purification, for the electric power generation in the fuel cell 3, and the purifier 4 purifies hydrogen from the exhaust gas discharged from the fuel cell 3. The offgas from the PEM 9 is used in a heater 8, and the offgas from the PSA 11 is used in the fuel cell 3.

  • Publication number: 20030015462
    Abstract: A gas liquid centrifugal separator conducts a gas-liquid separating treatment of a mixture comprising a liquid and a gas contained in the liquid to separate the gas and the liquid from each other. The separator includes a cylindrical vessel having an axis extending in a vertical direction, an exhaust port provided in a top wall of the cylindrical vessel for discharging the separated gas, a drainage port provided in a bottom wall of the cylindrical vessel for discharging the separated liquid, and an introducing port provided in a peripheral wall of the cylindrical vessel for introducing the mixture into the cylindrical vessel in order to conduct the gas-liquid separation treatment utilizing an inverted conical liquid surface formed by causing the mixture to travel circumferentially travel along an inner peripheral surface of the cylindrical vessel. Thus, the separation of the mixture into the gas and the liquid can be conducted reliably, and the internal structure of the cylindrical vessel can be simplified.

  • Patent number: 6302484
    Abstract: In an apparatus for permitting pass-through between a vehicle compartment and a trunk room of a motor vehicle, a first hook is provided on a forward foldable portion of a seat back of the rear seat, and a second hook that is engageable with the first hook is provided on the seat back. The first and second hooks are normally biased by coil springs in such a direction as to engage these hooks with each other. A vehicle-compartment-side strap and a trunk-room-side strap are provided for rotating the first hook and the second hook, respectively, so as to release the engagement of these hooks. A lock device is also provided for limiting rotation of the first hook while the forward foldable portion is in the upright portion, thus making it impossible to release the engagement of the first hook with the second hook by pulling the vehicle-compartment-side strap.
