  • Patent number: 8534167
    Abstract: An open end wrench includes a jaw portion having first and second jaws. The first jaw includes a sliding groove slideably receiving a slide. When the jaw portion is not engaged with a workpiece, the slide is in a free position. When the jaw portion receives the workpiece but does not drive the workpiece, a buffering space is formed between an abutting end of the guiding slot and a guide fixed in the sliding groove. When the jaw portion drives the workpiece and deforms elastically, the body rotates relative to the workpiece, but the slide does not rotate together with the body due to the buffering space such that the end of the slide remains in surface contact with a face of the workpiece. Also, a buffering angle can be formed between a wrenching face on the slide and the face of the workpiece when the jaw portion receives the workpiece but does not drive the workpiece.

  • Publication number: 20080048489
    Abstract: A bicycle rim assembling structure includes a plurality of through holes disposed equidistantly at a concave surface on an external side of a rim, and a corresponding number of eyelets are engaged into the through holes by a pressing machine. The eyelet is T-shaped with a distal edge of its broadened circular section at the top bent into an internal wall of a cannular hole, and the lowest section of its linear flat body section at the bottom bent into another cannular hole, and both upper and lower cannular holes have the same diameter, and the eyelets are engaged into the through holes. The space of the linear flat body section under the eyelet provides a function of adjusting the spokes, and the thickness of the eyelet provides sufficient strength to accept the pulling force applied to the eyelet after the spoke is installed to the rim to prevent accidents.

  • Patent number: 7266398
    Abstract: The present invention is a circuit that is set in a communication apparatus. The circuit is co-operated with a button of an audio receiving/transmitting device for triggering an on-hook or off-hook function when the communication apparatus receives an incoming call. The button is normally closed. The on-hook and off-hook functions are triggered by a triggering signal which is higher than a threshold value. Thus, the present invention doesn't execute the on-hook or off-hook function by an on/off button set in the communication apparatus but directly execute the button set in the audio receiving/transmitting device, which improved the convenience of the communication apparatus.

  • Publication number: 20070084279
    Abstract: An apparatus for controlling micro-fluid temperature is provided. The apparatus includes a chip, a fixed stand, a heat-absorption block, and an actuator. The chip has a reaction chamber for disposing a micro-fluid, and the temperature of the micro-fluid rises by heating the chip to reach the required reaction temperature. In the cooling-down operation, the heat-absorption block can contact the chip when pushed by the actuator, so as to dissipate the heat from the chip by way of heat conduction. Moreover, in the heating operation, the heat-conductive block is out of contact with the chip such that the micro-fluid in the chip is quickly heated, so as to reach the required reaction temperature of the micro-fluid rapidly.
