Abstract

PURPOSE:To prevent the deterioration of a permanent magnet caused by a hot temperature by applying magnetic field to the tube ball under exhaustion to magnetize the permanent magnet, and thus to reduce the property drift after completion and to increase the upper limit of the using temperature.
