Abstract: A bicycle generator including a coil stator and a magnetic rotor. The coil stator includes a planar support, and an induction coil portion formed by a plurality of series-connected coil units which are evenly spaced along the circumference of the planar support. The magnetic rotor is rotatable relative to and substantially parallel to the coil stator, and includes a permanent magnet having a plurality of magnetic pole pairs formed on its circumference. The number of coil units in the induction coil portion is equal to the number of magnetic pole pairs in the magnetic rotor, and the coil units is winded into trapezoid or sector shape, and the span angle of each of the magnetic pole in the magnetic rotor is substantially equal to the span angle of each of the coil units in the coil stator. Alternatively, the bicycle generator may comprises a cylindrical coil stator and a cylindrical magnetic rotor.

Abstract: The present invention relates to an ozone generating device, comprising: a main body, having a cavity, on the lateral sides further having a plurality of inlet holes, which connect the cavity to the exterior to let in air, and on the top side having a plurality of outlet holes, which connect the cavity to the exterior to let out air with ozone; two electrodes, attached to the bottom and the top side of the cavity, for generating an electric discharge, so as to generate ozone in the cavity; and a heating device, installed below the electrode at the bottom side of the cavity, so as to heat the electrode and, indirectly, air in the cavity; wherein heating the first electrode by the heating device allows the operating voltage for generating an electric discharge to be reduced and heating the air with ozone within the cavity causes it to drift upward and to flow out of the cavity through the outlet holes.

Abstract: An improved swinging type generator for use in automatic wrist watches is disclosed. It contains: (a) a base with a center shaft hole, (b) a stator mounted on the base containing at least one layer of ring-shaped coil plate having at least one periodic-wave-shaped induction coil arranged on and along a circumference of the ring-shaped coil plate; (c) an unbalanced-and-weighted swinging magnetic rotor having a central rotary shape. The rotary shaft is mounted in the shaft hole of the base, and the unbalanced-and-weighted swinging magnetic rotor includes a magnetic ring having a plurality of magnets arranged in a head-to-tail manner along a circumference of the magnetic ring.

Abstract: A method for making molds for use in manufacturing multiple-lead microstructures is disclosed. Each of the molds comprises a set of punch head molds and a set of matching die plate molds, and the method comprises the steps of (a) dividing the multiple-lead microstructure into a plurality of portions, each portion is to be prepared by a pair of a punch head, which contains a plurality of prutrusions, and a die plate, which contains a plurality of matching recesses; (b) preparing each of the punch head molds using a first lithographic technique; and (c) preparing each of the die plate molds using a second lithographic technique.
