Title: Production of magnetic head
Inventor: MATSUURA SHINJI
IPC: G11B5/60
Filed: 1990-03-26
Abstract: PURPOSE:To allow the easy polishing of a rectangular surface for sliding contact with a medium to a spherical surface by pressing a rectangular head body to a polishing member, applying load to the four corner parts of the head body and polishing the surface of the head body for sliding contact with the medium by the polishing member as it is. CONSTITUTION:The surface n1 of the head body 10 for sliding contact with the medium is pressed onto the polishing member 14 while this surface n1 is positioned downward and is held mounted to a pressing jig 13 by leg parts 11a,... of sliders 11, 12. The body 10 is pressed to the member 14 via the leg part 11a of the sliders 11, 12. Then, the pressing force acts only on the four corners of the body 10 and the thinned central part of the body 10 warps upward and floats from the member 14. The four corners pressed to the member 14 of the surface n1 of the body 10 are strongly polished and the central part warped from the member 14 of the surface n1 is polished more weakly in the parts further from the four corners if the member 14 is moved while this state is maintained. The warped body 10 restores the original shape and the surface n1 of the body 10 is therefore, made into the approximately spherical shape polished mainly at the four corners when the pressing of the jig 13 is released after the completion of the polishing.

Title: Method and device for painting out polygon
IPC: G06T11/40
Filed: 1992-03-31
Abstract: PURPOSE:To prevent an error between a painted-out part and an outline part from being generated by mutually inverting the painting-out order of the 1st and 2nd parts of the polygon. CONSTITUTION:When the polygon ACDB is painted out, the polygon is divided into two left and right polygons P1 and P2 with the straight line connecting the apex A having the largest Y coordinate and the apex D with the smallest Y coordinate. One polygon P1 is painted out from the apex A in the decreasing order of Y coordinates and the other polygon P2 is painted out from the minimum Y-coordinate point D to the maximum point A, i.e., from the bottom to the top inversely to the P1. Consequently, the generation direction of straight lines between the respective apexes at the time of the painting-out process can be matched with the generation direction of the straight lines at the time of an outline drawing process. Therefore, the same drawing points are generated at the time of the painting-out process and outline drawing process to eliminate the error between the painted-out figure and the outline.
