Title:
GRAVITY OBJECTIVE NEGATING DEVICE
Document Type and Number:
Japanese Patent JPS57201874
Kind Code:
A
Abstract:

PURPOSE: To negate the operation of gravity, by establishing a simultated natural dropping movement toward the direction opposing to the gravity and forming the phenomenon of static collision with an objective.

CONSTITUTION: When an equi-speed transfer device H is moved a point on a gravity graph simulated slide A formed in a curve indicating equation of natural drop is moved in parallel to move a piston I slided with the said slide. The piston I delivers a hydraulic pressure in a cylinder E to move a pison I' provided to another end of a linked cylinder and to displace a stand (d) fitted with the said piston I'. Further, the equi-speed transfer device is operated and the stand (d) is returned to the initial position with equal speed. The twice repetition of the processes allows the objective on the stand (d) to be negated against the operation of gravity.
