Abstract: A free-wheel hub transmission mechanism includes an axle, and an aluminum hub barrel and a driving barrel which are rotatably mounted on the axle. The driving barrel which carries a sprocket wheel has a threaded body portion extending into the hub barrel to connect to a coupling socket which transmits the rotation of the driving barrel to a reinforcing hollow body. The reinforcing hollow body is provided in and fixedly coupled to the hub barrel. The coupling socket is movable toward and frictionally engageable with the reinforcing hollow body upon rotation of the driving barrel in one direction and is disengageable from the reinforcing hollow body upon rotation of the driving barrel in another direction.

Abstract: A free-wheel hub transmission mechanism which includes a threaded axle coupled to the seat stays of a bicycle, a hub barrel fastened to the free-wheel spokes of the bicycle and disposed around the threaded axle, a driving barrel sleeved onto the threaded axle and having one end inserted into the hub barrel and an opposite end fastened to the free-sprocket of the bicycle, a coupling socket mounted within the hub barrel around the threaded axle, a conical spring mounted within the hub barrel around the coupling socket, a conical bushing and a cup mounted within the hub barrel to stop the conical spring inside the hub barrel, a plurality of ball bearings mounted around the threaded axle, and two lock nuts respectively threaded onto two opposite ends of the threaded axle, wherein the coupling socket is forced forwards into engagement with an inside annular flange of the hub barrel, causing the threaded axle and the hub barrel to be turned with the driving barrel when the driving barrel is rotated clockwise by the

Abstract: A foldable assembly cabinet having the parts thereof formed by injection molding can be collaped into a compact size without disassembly thereof for effective reduction of the packing volume so as to facilitate the delivery thereof in one aspect and lower the cost of transportation in another. The cabinet includes a case body, a left and a right side board, a top lid and a bottom board and a number of partition boards. The left side board and the right side board are pivotally secured to the case body and the right side board is made wider than the left side board so that the former can be folded in superposition on top of the latter; and the two side boards are located in abutment against the folded top lid and bottom board in the collapsing of the cabinet. Each of the side boards and top lid and the bottom board and the partition boards of the cabinet is provided with a grid-like reinforcement structure.

Abstract: This invention is directed to a method for making multiphase copper oxide based materials which have a phase having a zero resistance transition temperature above about 200K. The method comprises subjecting a copper oxide based material precursor to an oxygenation in an atmosphere comprising more than about 20% oxygen by volume at a temperature less than about 200.degree. C. for a time sufficient to form the material. The invention also is directed to maintaining the properties of a copper oxide based material having a zero resistance transition temperature above 150K.

Abstract: Superconducting films and devices are provided which exhibit an AC to DC conversion effect of an RF AC input signal. The films can be microscopically inhomogeneous with granular or columnar microstructures in layered or nonlayered structures, which provide the conversion effect with and without an applied magnetic field. The films also can be multilayer films which provide the conversion effect with a magnetic field applied to the films. The multilayer films are substantially compositionally homogeneous within the layers and the microscopically inhomogeneous films are substantially compositionally homogeneous throughout, but include structural inhomogeneities.
