Abstract

PURPOSE:To obtain the uniform total over-all periphery coating with ease and prevent the magnet from causing drop and adhesion of the magnetic powder, crack and breakage by coating polyparaxylene over the magnet with vacuum evaporation. CONSTITUTION:Polyparaxylene 2 of thermosetting resin is coated by vacuum evaporation all over periphery of a rotor magnet 1 for a micro miniature stepping motor used in watches, for example.
