Abstract
PURPOSE: To make it possible to form an accurate gap efficiently and easily by forming a lamination core block by using a lamination plate of two kinds of thin- plate magnetic materials joined by turns and then by slicing the block.
CONSTITUTION: In magnetic-substance ferrite block 8, notch grooves 11 keeping constant interval (t) are made at constant interval T, and this block and metal magnetic-substance thin-film ribbon 12 are alternatively joined by glass to obtain a lamination plate. At the same time or after joining, grooves 11 are molded by glass 10. Next, the plate is cut at equal-distance positions 14, 15...20 between adjacent notch grooves and end parts 13 and 21 and then each surface is smoothed. This lamination block is cut like 22 and 23 and in each block, coil winding window groove 26, coil frame grooves 27 and glass-joining galss sink 28 are made. The glass mold part should have (m), greater than the gap depth, left. Core half blocks formed in this way are joined together by melting glass 10 and 38 with magnetic thin plates 12 agreeing. Next, a munufactured gaped bar is sliced at fixed positions to remove guide parts 40 and front faces are polished to obtain head cores.
