TITLE OF THE INVENTION
Rotation promoting means for rotating shaft and power
generation system provided with said rotation promoting
means.
BACKGROUND OF THE INVENTION
The present invention relates to rotation promoting
means for accelerating rotation of a rotating shaft, and
also to a power generation system provided with said
rotation promoting means.
In Japan, electric power is generated by nuclear,
hydroelectric, and thermoelectric power plants. Despite of
severe controversy from safety reasons, the Government has
an intention to rely on nuclear power generation because it
is more a'dvantageous in cost than thermoelectric and
hydroelectric power generation at present.
In obtaining energy through rotation of a power
generator directly rotated by a motor, there is obviously
no benefit viewed from the law of energy conservation.
Thus, no basic concept is known yet to obtain electric
power industrially through rotation of a power generator
by a motor.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide

rotation promoting means for a rotating shaft, which is
operated by gravitational force without supplying energy
from outside.
It is another object of the invention to provide a
power generation system equipped with rota~ion promoting
means, which is operated ~y gravitational force.
The arrangement of the present invention is character-
ized in that a plurality of weights are rotatably mounted
with spacings on outer periphery of a rotating wheel, which
is mounted on a rotating shaft, that said weights are set
in open position and project outwardly when moving down
in rotating direction, and the weights are set in closed
position when moving up in rotating direction, and that
there are provided a motor for rotating said rotating shaft
and a power generator for generating electric power when
rotated by said rotating shaft.
After all, the present invention is based on a
principle that the rotating shaft is equipped with means
for promoting rotation by gravitational force when a power
eenerator is directly rotated by a motor, and surplus energy
is obtained by gravitational force and power is generated
in economically and industrially feasible manner.
The above and other obJects and advantages of the
invention will become more apparent from the following
description.

BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a general view schematically illustrating an
embodiment of the present invention; and
Fig. 2 is a side view schematically illustrating the
above embodiment of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In the following, description will be given on an
embodiment of the present invention in connection with the
drawings.
The embodiment comprises a starting motor 1, a belt
(chain) 5 stretched between a small diameter pulley 2 of
said starting motor 1 and a large diameter pulley 4 of a
rotating'shaft 3, rotation promoting means 6 mounted on the
rotating shaft 3 on both sides of said large diameter pulley
4, and a belt (chain) 10 stretched between a small diameter
pulley 8 of a power generator 7 and a large diameter pulley
9 of the rotating shaft 3.
As shown in Fig. 1 and Fig. 2, the rotation promoting
means is designed in such arrange~ent that a plurality o~
weights 111 are rotatably supported on a plurality of shafts
13, which are mounted on a recessed groove 11 on outer
periphery of a rotating wheel 12. Therefore, when the
wheel is rotated in the arrow direction in Fig. 1 and the

weights are moved down in the rotating direction, they are
set in open position by self-weigh-t and project outwardly.
When the weights are moved up in the rotating direction,
they are set in closed position and are brought into contact
with the recessed groove 11. As the result, the weights on
the right side of Fig. 1 mounted on the wheel 12 are in
open position and the weights on the other side are in
closed position at all times. Thus, rotary moment is
generated, and the rotation of the rotating shaft 3 is
promoted.
In the above embodiment, the rotation promoting means 6
are mounted one on each side of the shaft, while more than
one, e.g. 10 each, of such means may be provided, and the
number of such means may be properly selected according to
the size'of the rotation promoting means and electric power
to be generated.
The rotating shaft 3 of the rotation promoting means 6
is supported by bearings 16 and 16'. The power generator 7
is rotated through the belt 10, which connects the large
diameter pulley 9 mounted on one end of the rotating shaft 3
and the small diameter pulley 8 of the power generator 7,
and power is generated.
In the above embodiment, a recessed groove 11 is formed
on outer periphery of the wheel 12 so that the weights 1~1
are brought into contact with and stopped by said recessed

groove 11. However, the invention is not limited to this,
and stoppers may be used, for example.
In the above embodiment, the pulley 2 mounted on the
rotating shaft of the motor is designed with small diameter
and the pulley 4 mounted on the rotating shaft 3 is designed
with large diameter. The reason for this is to slow down
the rotating speed of the rotating shaft because, if the
rotating speed of the shaft is too fast, all weights may be
set in open positions by centrifugal force.
Because the rotating shaft 3 is also rotated by the
rotation promoting means 6, there is no need that the
starting motor 1 is operated at all times, and the motor may
be turned on and off with a certain time interval.
The application of the rotation promoting means 6 of
the present invention is not limited to the rotation of the
power generator, and it may be used for rotating any type of
wheels. In summing up, it can be used for any application
for promoting and accelerating the rotation of a rotating
wheel by mounting on a rotating shaft of the rotating
wheel.
Next, description will be given on the operating
principle of the present invention wikh the above arrange-
ment.
When the rotating shaft 3 is rotated by the rotation of
the starting motor 1 through the belt 5, the wheel 12 is

rotated as shown in the figure. The weights 14 on the wheel
12 are set in open position when the weights are moving
downward, and the weights are set in closed position when
moving up. Thus, rotating force generated by rotary moment
is given to the rotating shaft 3, and the rotation is
promoted. ~hen the rotating shaft 3 is rotated, the power
generator 7 is rotated through the belt (chain) 10, and
electric power is generated.
According to the present invention, a force to push the
rotating shaft downward is applied by the principle of
seesaw and this force is converted to surplus electric power
generated by energy other than the motor.
As described above, it is possible according to the
present invention to promote the rotation of the rotating
shaft bedause the rotation promoting means operated by
gravitational force are provided without supplying energy
from outside. Thus, electric power with higher energy can
be generated than the energy given to the power generator
by the motor. This surplus energy corresponds to the energy
given by the gravitational force, which is supplied free of
charge.
