Abstract

PURPOSE:To simplify the centering in a cutting work, by providing a conical semisphere recess at the center of the external surface of each disc of a ferrite core in a structure wherein discs are added to both end surfaces of a cylinder. CONSTITUTION:In the ferrite core 21, conical recesses 22 are provided at the center of the both end surfaces thereof. The conical recess 22 serves for an easy centering when working (cutting) the cylindrical ferrite into a drum. A semisphere recess has also the same effect.

Description

【発明の詳細な説明】 本発明は、ドラム型フェライトコアを使用したインダク
