Title:
DEVICE FOR UTILIZING LARGE MAGNETIC FORCE WITH SMALL FORCE
Document Type and Number:
Japanese Patent JPS58123380
Kind Code:
A
Abstract:
PURPOSE:To enable to utilize the large magnetic force of a magnet with small force by moving the magnet with attracting and repelling forces between magnets. CONSTITUTION:The total of repelling forces between repelling magnets 1 and 3, and between 2 and 4 is equalized to that of attracting forces between attracting magnets 1' and 3', and between 2' and 4'. While these magnets simultaneously turn at 90 deg. in a direction of arrows cooperatively, the repelling forces between the same polarity of the magnets 1-4 decrease inversely proportional to the square of the distance, and the repelling forces between the different polarity of the magnets 1'-4' decrease inversely proportional to the square of the distance. While these magnets then simultaneously turn at from 90 to 180 deg., the attracting forces between the different polarity of the magnets 1-4 increase inversely proportional to the square of the distance, and the attracting forces between the same polarity of the magnets 1'-4' increase inversely proportional to the square of the distance. Accordingly, since the repelling forces are equal to each other at any moment while they turns 180 deg., these movements do not require force which resists against the repelling forces.
