Title:
GRAVITATIONAL FIELD MOTION TYPE GRAVITY MEASURING SYSTEM
Document Type and Number:
Japanese Patent JP2007093568
Kind Code:
A
Abstract:
To provide a light-weight gravimeter convenient for carrying.
By shifting the standpoint from falling rate of a measuring object, elongation of a spring, and magnetic repulsion to which conventional devices paid attention to gravitational field curve, gravity G is known by change in weight, caused by motion of an object within the gravitational field curve. Power is transmitted from a motor 1 to a rotator 3 which is horizontally arranged via a belt 2 to give a high rotational speed thereto.
