    摘要: A device for measuring the imbalance of a disc-like object has at least three load sensors having cantilevers for supporting the object at their corresponding measuring points selected, with a same angular distance therebetween, on a measuring circle which is concentric with a circular through-hole of the object. Each of the caltilevers is extended tangential to the measuring circle and directed perpendicular to the line of sight in the same sense when viewed from the center of the through-hole. A positioning device positions the center of the through-hole in the object relative to the load sensors, and a calculator device for calculating the imbalance of the object using the data supplied from the plural load sensors.

    摘要: A plurality of bar-like magnets are arranged in a vacuum chamber at an equal space interval to form a plurality of strong magnetic fields in a stripe-pattern form and the magnets are moved reciprocally in the direction of arrangement of the magnetic fields while changing gradually the stop points of the magnets over a work to be processed by etching or sputtering in a step-like manner so that the integral effect of each magnetic field acting on the work is uniform over the entire region of the work.
