Damage prevention manner null of the magnetic arrival target surface in magnetic arrival

摘要

PURPOSE: To cause powerful magnetization action for an attraction surface to keep and prevent damages due to removal by a method wherein a magnet is placed in a recess part of a magnetic plate provided on the back surface of a magnetization fixing body, and a coating material for preventing damages is applied to the surface to form a film. ;CONSTITUTION: A magnetic plate 2 extends a marginal cylindrical part 2b surrounding a circular plate 2a that an object supporting projection part 1 is provided in a central part, to form a recess part in a marginal cylindrical part. A circular magnet 3 engages with this recess part and a coating material is applied from an outer peripheral surface of a marginal cylindrical part to a surface of the magnetic 3 to form a coating film 4. With the use of resin that polybasic acid and polyvalent alcohol are combined, various compounds of the polybasic acid and polyvalent alcohol are suitably selected and arranged, whereby the coating material is made by regulating performance of the coating film 4. Thus, it is possible to keep an original magnetic force for any length of time without generating a contact abrasion on a surface to be magnetized.;COPYRIGHT: (C)1995,JPO
