    摘要： Disclosed herein is a magnetic head in which the sliding surface is constructed of a transducing gap, a pair of soft magnetic metal films opposite to each other through the transducing gap, and a substrate holding the soft magnetic metal film. The substrate is 20-200 times as wear-resistant as the soft magnetic metal film. The magnetic head has a gap depth of 1-5 .mu.m and produces an overall high head output.

    摘要： A grinding machine including a grinding wheel spindle motor for rotating a grinding wheel, a workpiece spindle motor for rotating a workpiece such as a gear to be ground in mesh with the grinding wheel, and a traverse motor for moving a table supporting the workpiece spindle motor. A power detector and a comparator are connected to a driver circuit for the grinding wheel spindle motor. When a load on the grinding wheel in mesh with the workpiece is increased, such a load increase is detected by the power detector and applied to a comparator. If the load signal is in excess of a reference level, then the application of a drive signal to the traverse motor is interrupted or a speed at which the workpiece is traversed relatively to the grinding wheel is reduced.
