<P>PROBLEM TO BE SOLVED: To solve the problem that in a conventional suspending vertical movement type variable gravity device, a flywheel is required, and accompanying an increase in size, out of consideration peculiar to a rotary machine, a load in manufacturing costs becomes high; and for transmitting rotation in both normal and reverse directions in a torque conversion mechanism in order to achieve appropriate acceleration and deceleration, strings of a special specification need to be procured, becoming an obstacle in reduction of the manufacturing costs. <P>SOLUTION: A moving body having substantially the same mass as a capsule is alternately reciprocated in the vertical direction with the capsule in place of the flywheel. Therefore, consideration for a rotary body having a large mass is not required. Further, by a mechanism of winding and winding back the strings respectively suspending the moving body and the capsule by two coaxial spiral pulleys, basically, as tension is always applied by gravity, a high tensile strength string that is normally commercially supplied can be used. <P>COPYRIGHT: (C)2012,JPO&INPIT |
