  • Patent number: 6029734
    Abstract: A slat-lifting mechanism of the Venetian blind is composed of a slat set, a pull set, a slat pull cord, and a locating set. The slat set has a plurality of slats. The pull set has a pull cord member and a spring retrieving unit which is linked with the pull cord member. The slat pull cord has one end that is put through the slat set, and other end that is fastened with the pull set. The locating set is disposed in the traveling path of the slat pull cord and is capable of bringing about a friction resistance which is greater than a retrievable pull force of the spring retrieving unit for overcoming the pulling force of the slat pull cord, so as to control the pulling or the releasing of the slat pull cord. The slat set can be thus located by the locating set.

  • Patent number: 6024154
    Abstract: A Venetian blind lifting mechanism is composed of a slat set, a winding member, a slat winding cord, and a locating member. The slat set has a plurality of slats. The winding member has at least one cord pulling member and at least one spring releasing unit which is linked with the cord pulling member. The cord pulling member has one end which is extended through the slat set, and other end which is fastened with the cord pulling member. The locating member has a retaining member capable of bringing about a retaining force to overcome the rewinding force of the winding member so as to stabilize the cord pulling member.

  • Patent number: 5908603
    Abstract: An integrated ozone generator is disclosed. It includes: (a) an upper covering layer having a thin film, and a permanent magnet being installed on the thin film, the permanent magnet having a periphery which is surrounded with a coil on which a plurality of contact points are installed for inputting an oscillating signal, so as to form an electromagnetically actuating micro pump, the upper covering layer further having a hole formed on a first side of the upper covering layer and an upper thin film electrode and a discharging teethed structure installed on an inside surface of the covering layer away from the hole; and (b) a base having a groove which is connected with an inner hole of the upper covering layer to form a gas chamber, a gradually opened channel at one side of the gas chamber for inputting gas, and another gradually reducing channel at another side of the gas chamber.

  • Patent number: 5874792
    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.

  • Patent number: 5733512
    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.

  • Patent number: 5351136
    Abstract: A FAX-receiving-and-output device for secret information and method therefore, which comprises a first and a second information transmission channels for transmitting non-secret information and secret information respectively; the second information transmission channel includes a memory for storage of secret information, and a memory for storage of identifying code and memory address of a secret information. To transmit a secret information, the sender first inputs the identifying code of the intended recipient of that information before transmitting that secret information. An identifying module at an receiving terminal would recognize such identifying case, and the secret information will be stored in a memory.
