  • Patent number: 7002100
    Abstract: A laser assisted machining method and device comprise a tool mount on which a laser head is disposed. A digital thermometer is disposed in a machining tool or on the tool mount for feeding data to a system controller. A laser is used to enable the blade of the machining tool to heat and soften a workpiece instantaneously. As the machining process is in progress, the chip is rapidly removed. The temperature of the tool tip is monitored by the digital thermometer for automatic control of the temperature of heating the workpiece by the laser, thereby keeping the temperature of the tool tip in a specific allowable range. The efficiency of the machining process and the surface precision are thus enhanced.

  • Patent number: 6935213
    Abstract: A mechanism for changing direction of exerted force of wrench having a ratchet wheel is disclosed. In an enclosed box portion of the wrench there are provided an opening, a C-shaped seat on a bottom of the opening, the C-shaped seat having a C-shaped groove, a ratchet wheel disposed in the opening, a pawl in a first cavity, an upright swing assembly in a second cavity, and a ring for retaining the ratchet wheel in place. Counterclockwise turning the swing assembly will bias one steel ball against the pawl for engaging the pawl with the ratchet wheel, thereby causing the wrench to exert force toward a direction. Alternatively, a clockwise turning of the swing assembly will cause the wrench to exert force toward a reverse direction. Further, clockwise turning the wrench will cause the ratchet wheel to be inoperative, thereby adjusting an angle of the exerted force.
