  • Patent number: 7489143
    Abstract: A fixed electrode and a movable electrode to be used to drive each arm are formed at a drive unit. As a voltage is applied between the fixed electrode and the movable electrode, the movable electrode is caused to move by coulomb force, thereby driving the arm 3 in a closing operation. By detecting a change occurring in the electrostatic capacity between the fixed electrode and the movable electrode at this time, a decision can be made as to whether or not the sample has been gripped.

  • Patent number: 7339383
    Abstract: A fixed electrode and a movable electrode used to drive each arm are disposed at a drive unit. As a voltage is applied between the fixed electrode and the movable the electrode, a coulomb force causes the movable the electrode to move, thereby driving the arms along the closing direction. The dimensions of a sample can be measured based upon the electrostatic capacity achieved between the electrodes when the sample becomes gripped by the arms.

  • Patent number: 7048264
    Abstract: A liquid-filled engine mount is disclosed which includes a rubbery elastic member interposed between an engine and a vehicle body, a diaphragm positioned in opposed relation to the rubbery elastic member. The engine mount defines a liquid chamber therein. The liquid chamber holds an actuating liquid therein. The liquid chamber has a partition wall disposed therein. The partition wall separates the liquid chamber into primary and secondary chambers. The primary chamber is provided on a side of the elastic member while the secondary chamber is provided on a side of the diaphragm. The partition wall has first and second orifices extending therethrough. The first orifice communicates with both the primary chamber and the secondary chamber. The second orifice communicates with the primary chamber. The first and second orifices provide different resistances to the liquid flowing therethrough.
