  • Patent number: 7871503
    Abstract: An electrochemical discharge machining device includes a base, a sensor disposed on the base, a shaft rotatably disposed on the base, an electrode disposed at one end of the shaft and contacting with a work piece, an isolating element disposed between the sensor and the shaft, and a control module connected to the sensor. Current flows to the electrode via the shaft to machine the work piece, and the force exerted on the electrode by the work piece is transmitted via the shaft and the isolating element to the sensor converting the force into a signal sent to the control module for raising or lowering the base to maintain contact between the electrode and the work piece. The sensor serves as a detecting mechanism to ensure appropriate contact between the electrode and the work piece.

  • Patent number: 7447021
    Abstract: An air conducting cover for a server includes a recess portion, a guiding portion, and a connecting portion. The guiding portion upwardly and outwardly extends from an end of the recess portion. The connecting portion horizontally extends from an end of the guiding portion and is attached to the server. The server includes a server motherboard bracket and a server motherboard installed on the server motherboard bracket. The air conducting cover is disposed on the server motherboard bracket and combined with the server motherboard bracket as an airflow channel.

  • Publication number: 20080202572
    Abstract: An automated awning comprises a main shaft connected to a screw rod through a sleeve by a screw means. The screw rod is driven by a motor to activate a first support rod and a second support rod to slide forward or backward sliding motion. A main support bracket is disposed between the main shaft and a second support rod, and a spring is disposed between the main support bracket and the main shaft. There are deep and shallow grooves and a slopped surface within the second support rod; a free rotor and a fixed rotor are inserted therein. A tube body is mounted on a motor mount and enclosing the first support rod. The tube body is then inserted into an outer tube. As the screw rod drives the first and second support rods forward, a gear teeth strip on one side of said first link rod stretches a spring so as to open a sun roof by extending the second main support rod, the second link rod and the third main support rod; the rotors are retained on the slopped surface for fixing the main support bracket.
