Abstract: An improvement to electrical bicycles is provided. The bicycle is improved by directly securing a one-way driving assembly to the left side of the driving wheel's hub and forming a one-piece unit with the hub. By having an inserting body protruding from a rotating body, a large bevel gear wheel of the driving assembly is joined with the rotating body. An output bevel gear wheel of a D.C. motor is engaged with the large bevel gear wheel to directly drive the hub in a forward direction. The hub may also be pedal driven so the function of the pedals is not changed.

Abstract: A three dimensional module for housing a plurality of integrated circuit chips is shown. The IC chips are mounted in rows on a plurality of substrates. Parallel to each row are communications bars which provide signal paths allowing chips on one substrate to communicate with those on another substrate. The communications bars also serve as spacers between substrates, thereby forming cooling channels. The IC chips are disposed in the cooling channels so that they come into direct contact with the cooling fluid. Signal lines to and from the IC chips are kept as separated as possible from the power lines so as to minimize noise. To this end, relatively thick power supply straps are mounted to each substrate below each row of IC chips. The power supply straps are, in turn, connected to power feed straps such that a very low impedance power supply path to the IC chips is maintained.

Abstract: 1,4-butanediol is prepared from allyl alcohol containing allyl acetate and water. The allyl alcohol is subjected to a hydroformylation reaction in the presence of an organic solvent, a rhodium complex, and a phosphorous compound under an atmosphere of carbon monoxide and hydrogen, to produce a hydroformylation product, which is extracted with an alkaline aqueous solution in the presence of carbon monoxide and/or hydrogen. After the extraction, an extracted raffinate solution containing the rhodium complex in the organic solvent is recycled through the same hydroformylation process, while the extracted aqueous solution containing the hydroformylation product is subjected to a hydrogenation reaction in the presence of hydrogen, with a hydrogenation catalyst added, to produce 1,4-butanediol.

Abstract: A three dimensional thin-film interconnector is fabricated by depositing a dielectric layer onto the surface of a substrate, depositing a layer of conductive material onto the dielectric layer to form a signal plane, depositing a dielectric layer onto the surface of the signal plane, forming a plurality of through holes in the dielectric layer that extend to the signal plane, and filling the through holes with an electrically conductive material to form vias. The sequence of forming a signal plane, depositing a dielectric layer, forming a plurality of through holes, and filling the through holes is repeated until a predetermined number of signal planes and a predetermined arrangement of vias are obtained. The through holes are formed at locations in the dielectric layers corresponding to both predetermined electrical connections and the vias in a preceding dielectric layer. The signal planes are formed at different locations on the substrate.
