摘要： The present invention comprises various embodiments of a power vise in which a supplementary power source is used to open and close the jaws. All embodiments may be actuated by a remote control, so the operator may have both hands free to hold the workpiece as it is placed in or removed from the vise. All embodiments may also include means for regulating the pressure developed between the jaws. A first embodiment is an electrically operated vise. The output shaft of an electric motor is connected to the advance screw of the vise to turn the screw and close or open the jaws. A second embodiment includes a hydraulic ram, with a first jaw affixed to the hydraulic cylinder and a second jaw affixed to the piston rod of the hydraulic device. Hydraulic pressure is used to retract and extend the piston rod, thereby closing and opening the jaws.

摘要： A synchronous demodulator is configured so as to extract gyroscope positionnformation in a polar coordinate format and then resolve it into position information in a more useful cartesian coordinate format. The technique involves integration of a gyroscope cage coil signal over integration intervals controlled by spin reference signals rather than by the commonly noisy cage coil signal. Integration of the cage coil signal over intervals controlled by the spin reference signals yields outputs of .lambda. cos .theta. and .lambda. sin .theta. which are subsequently sampled and held and then summed to produce a precession coil drive signal whose phase is in the proper relationship to make the gyroscope precess in the correct direction.
