Abstract

PURPOSE:To make the motion of a solenoid precise to a minute signal, by mounting a permanent magnet to an armature of the solenoid, mounting to a coil part another permanent magnet corresponding to the former and supporting the armature by the functions of these permanent magnets without a help of mechanical means. CONSTITUTION:A permanent magnet 13 is buried in the center of an armature 12 of a solenoid with upper end being the S and lower end the N, and another permanent magnet 14 is buried in a coil part 11 just below the armature 12 to form a solenoid with upper end being the N and lower end the S. When the coil part 11 is fed with either an AC or DC current, the permanent magnets 13, 14 repel each other so that the armature 12 can be supported in a suspended state. This kind of support replaces support by mechanical means, resulting in a preciser and more stabilized responsive motions to a minute signal.
