  • Patent number: 6280454
    Abstract: A head acupuncture instrument is disclosed. The head acupuncture instrument includes headgear with electrode probes mounted thereon, a wire dispenser, a plurality of wires extending from an electricity supply to the electrode probes via the wire dispenser, and a column with a bottom end secured to the headgear and a top end extensively received in the wire dispenser. The electrode probes offer stimulating current to acupuncture points needed to be stimulated in a patient's head.

  • 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: 6012506
    Abstract: A Venetian blind is provided with a slat-lifting mechanism consisting of a slat set, a slat pull cord, and a constant torque pull set. The slat set has a plurality of slats. The slat pull cord is connected with each of the slats of the slat set and is put through the bottommost end of the slat set. The constant torque pull set is disposed at the top end of the slat set and composed of a pull cord member and a constant torque spring unit which is linked with the pull cord member and provided with a constant torque spring which has a constant retrieving force enabling the pull cord member to rewind. The constant retrieving force of the constant torque spring must meet the condition of W-Fs<R<W+Fs, in which W stands for a total weight of the slat set; Fs, a system static friction force; and R, a retrievable elastic force of the constant torque spring.
