Abstract

PURPOSE: To avoid the strain caused by the melt-sticking with other cores as well as the cracking, melt-sticking previously the gap forming glass to the side of the gap opposing face of a core block and also setting both the glass surface and the gap opposing face at the same level through the finishing into the mirror surface.
CONSTITUTION: A pair of U-shaped blocks 6 and 6' made of the Mn- and Zn- ferrites are jointed together by fusing glass rods 7 and 7' and then divided vertically into two parts. Then both glass melt-stuck surfaces 8/8' and reinforcement glass surfaces 9/9' are set at the same level through the simultaneous finishing into the mirror surface. In this case, the glass relief groove 10 is formed on surface 8 to be used when forming the gap. At the same time, sputtering films 11 and 11' equal to the gap length are formed on surfaces 8 and 8' with SiO2 or the like. Then the block is cut off to obtain core 12. On the other hand, slider groove 14 is formed to block 13 made of the I-shaped Ni- and Zn- ferrites, and then slider 15 is cut out with end face 16 finished into a mirror surface. Then core 12 is put accurately onto the center of slider 15, and a weight is put on core 12 after fixing the core to guide tool 19 via the instant adhesive. Then reinforcement glass 9 and 9' are poured into the gap through the heat treatment to be melt-stuck. And the finishing process is given.
