Abstract
PURPOSE: To prolong the lifetime of a display unit by eliminating its trouble and by reducing aging variation, by employing a simple constitution where a ball only floats in a liquid in an airtight container wound with a coil.
CONSTITUTION: Airtight container 1 of a non-magnetic substance is a cylinder with one end made spherical for display part 2. The moment a current flows through coil 7 wounded around its out circumference, a magnetic field is generated around coil 7 and ball 4 moves in liquid 5 so that a vertical magnet will be horizontal. As a result, the magnet in ball 4 can be seen standing upringht through display part 2 while the current is not flowing and it can be seen at a level once the current flows. Namely, ball 4 turns by 90°. Since the rotational angle varies with the strength of the current, it serves as a simple meter.
