Abstract

PURPOSE: To obtain a core simply and efficiently, by eliminating the need for complicated machinework by manufacturing a vessel conforming to an external form of a fixed core with synthetic resin and by filling and enclosing ferromagnetic substances into the vessel.
CONSTITUTION: A fixed core 1 is composed of a vessel 5 in synthetic resin according with an external shape of the fixed core and ferromagnetic substances 6 filled in the vessel. Thermoplastic synthetic resin, such as polypropylene, polyethylene, etc. is used as synthetic resin constituting the vessel 5, and the separateness or its mixture of an oxide of metal, such as nickel, chrome, etc. is employed as the ferromagnetic substances 6 in a powdered or granular shape. These ferromagnetic substances 6 are admitted from an inlet 7 of the vessel 5, and the ferromagnetic substances are enclosed by screwing a screw 8 into the inlet 7 after filling the ferromagnetic substances while contact among the ferromagnetic substance 6 is compacted by the push force of the screw 8. Thus, the fixed core can be acquired simply and efficiently because complex machinework becomes useless.
