Title: Vertical magnetization reproducing method and its magneto-resistance effect head
Inventor: SASAKI KIYOSHI
IPC: G11B5/39
Filed: 1982-10-14
Abstract: PURPOSE:To attain reproduction of a vertical magnetization signal, without electric leakage even with a conductive recording medium, width loss, gap loss, having high magnetic flux utilizing element of an MR element and high reproducing efficiency. CONSTITUTION:The magnetic flux generated from the signal magnetization recorded on a vertical recording medium 8 is led to the lower end of a permeability thin film 7, led to the lower end of the MR element 4 from the upper end, passes through the permeability body 1 from the upper end and returns to a soft magnetic layer 8' at the rear side of the medium 8. Thus, the width loss in the single MR head and the gap loss in the shield MR head are avoided. Further, the size of a notch groove 2 is designed to a degree that this head does not act like a gap of the so-called shield from MR head at recording wavelengths to be reproduced.

Title: Grinding finish method for ball screw groove
Inventor: HAYASHI SADAO
IPC: B23G1/38
Filed: 1992-06-17
Abstract: PURPOSE:To accomplish ball screw groove working with high accuracy and to reduce the grinding work time by moving a grinding wheel formed in a specified manner in the directions of x-axis and y-axis by a distance equivalent a grinding finishing margin. CONSTITUTION:A grinding wheel 5 is formed narrower than a ball screw groove 1, and the grinding surface thereof 7 is formed in a shape substantially equal to the final contour shape of the ball screw groove 1, so that the grinding wheel 5 is first overall brought into contact and engaged with one side surface of the ball screw groove 3. One side surface of the ball screw groove 3 is ground and finished by feeding the grinding wheel 5 in the directions of x-axis and y-axis by a distance equivalent a grinding finishing margin. After that, the grinding wheel 5 is moved in the direction of x-axis to bring the grinding surface of the grinding wheel 5 into contact with the other side surface of the ball screw groove 3, and the grinding wheel is fed in the same manner as described above only by a distance equivalent a grinding finishing margin simultaneously in the directions of x-axis and y-axis to complete grinding finish. As the grinding surface of the grinding wheel 5 is simultaneously brought into overall contact with the ball screw groove 3, no local contact is caused so as to accomplish ball screw groove working with high accuracy. Furthermore, as the moving distance of the grinding wheel 5 is small, the grinding finishing time can be reduced.
