Abstract

PURPOSE:To generate a large mechanical energy with a small electric power consumption without being influenced by a severe locational condition caused by such as weather condition by converting the magnetic force of permanent magnet and gravity by the use of the specific gravity difference between magnetic fluid and nonmagnetic body and magnetic force. CONSTITUTION:In an arch-shaped pipe 20 of a turning assembly 2 magnetic fluid 21 and nonmagnetic body having a larger specific gravity than that of the magnetic fluid and the pipe 20 is sealed. After the center of gravity of this assembly 2 is positioned stationarily at a vertical plane and downward, the magnetic fields of permanent magnets 32, 33 having proper magnetic force are applied alternately to the magnetic fluid from the lower side of one end or the other end. Accordingly the nonmagnetic body receives a certain magnetic levitation according to the magnetic field to levitate or move above one end or the other end, and then the mass distribution in the arch-shaped pipe is varied by the specific gravity difference between the magnetic fluid and the nonmagnetic body. In association therewith, the center of gravity of the turning assembly 2 moves to a high position and torque is generated by the gravity acting onto the center of gravity, thereby turning the assembly 2.

That is, that is, the center of gravity of the rotating assembly is the axis 20 of the shaft 20a.
When the magnetic fluid 21 in the arcuate tube receives the magnetic field of one permanent magnet 32 having an appropriate magnetic force from below, on the vertical surface 20n formed by moving l up and down and below The plurality of non-magnetic spheres are subjected to a constant magnetic levitation force according to the magnetic field thereof, and are pushed up from the bottom position to a high position in the arcuate tube as shown in FIG. As it floats and moves, the mass distribution in the arcuate tube changes due to the difference in specific gravity between the magnetic fluid and the non-magnetic sphere. Simultaneously with the change of the mass distribution, the center of gravity of the rotating assembly 2 moves to the other end side and to a high position, and due to the gravity acting on the moved center of gravity, the rotating group with the center 20m of the shaft 20a as a fulcrum. An unbalanced state of the mass on one end side and the other end side of the solid body is created.

By creating this unbalanced state, the rotation assembly 2 moves at the other end side where the center of gravity moves at the same time that the plurality of non-magnetic spheres 22 move about the center 20m of the shaft 20a. It begins to rotate clockwise by descending from the position. That is, the center of gravity moves to the other end side and the high position, and the torque acting in the clockwise direction generated by the gravity acting on the moved center of gravity causes the permanent magnet 32 on one side to move.
Exceeds the starting resistance torque that acts in the counterclockwise direction due to the force for attracting the magnetic fluid 21 and the resistance force such as frictional resistance and inertial resistance that acts on the rotation assembly, and the rotation assembly 2 moves clockwise. Start turning. The photoelectric switch LS6 detects the slight displacement at the start of the rotation based on the presence or absence of the other end face 20f, and the control device 5 receives the OFF signal to excite the coil C4 and to generate the magnetic pole of the magnetic field generated by the excitation. The rotation of the rotation assembly 2 is promoted by the repulsive force with the magnetic poles of the permanent magnet 32, and the force exerted by the magnetic field of the permanent magnet 32 does not reach to a certain extent. The rotated displacement is detected by the photoelectric switch LS7, the coil C4 is demagnetized by the action of the control device 5 which receives the OFF signal, and the magnetic field of the permanent magnet 32 stops acting on the magnetic fluid 21 having superparamagnetism.

Next, as shown in FIG. 5, the plurality of non-magnetic spheres 22 move, the other end surface 20f of the arcuate tube 20 is located below, and the other end having an appropriate magnetic force is provided near the bottom. The magnetic field of the permanent magnet 33 acts on the magnetic fluid 21 from below. Due to the action of this magnetic field, the plurality of the non-magnetic spheres floats and moves to one end side in the arcuate tube and at a high position, and due to the difference in specific gravity between the magnetic fluid 21 and the magnetic spheres 22, the arcuate tube 2
At the same time the mass distribution in 0 also changes, the swivel assembly 2
The center of gravity of the shaft moves to the one end side and the high position, and the gravity acting on the center of gravity causes the rotating assembly 2 to start rotating counterclockwise about the center 20m of the shaft 20a as a fulcrum. This slight displacement at the start of rotation is detected by the photoelectric switch LS4 to excite the coil C5, and its repulsive force with the permanent magnet 33 promotes its rotation, so that the force exerted by the magnetic field of the permanent magnet 33 does not reach a certain extent. To the position where the coil C
As the magnetic field does not act on the magnetic fluid, the rotation speed thereof further accelerates with time and the potential energy is converted into kinetic energy, and one end of the rib 20 g of the flanged retaining pin outer cylinder It stops by hitting, and the rotating motion is repeated intermittently and alternately.

Thus, the magnetic fluid 2 in the arcuate tube 20 is
1 permanent magnets 32 and 33 having appropriate magnetic force from below
Magnetic field is alternately applied, and the non-magnetic sphere 22 put in the arcuate tube 20 is magnetically levitated from the bottom position on one end side or the other end side of the arcuate tube to the other end side or the one end side. Floating / moving to a high position, and due to the difference in specific gravity between the magnetic fluid and the non-magnetic spherical body, the center of gravity of the rotating assembly 2 is simultaneously moved to the high position on the other end side or the one end side, and acts on this center of gravity. Due to the gravity, the unbalanced state of the masses on the one end side and the other end side is created with the center 20m of the shaft 20a as the fulcrum. By creating this unbalanced state, the rotation assembly 2 starts to rotate clockwise or counterclockwise. This slight displacement at the start of rotation is detected by the photoelectric switch LS4 or LS6, and the coil C4 or C5 is alternately excited for a very short time by the action of the controller 5 which receives the signal, and the electromagnetic force generated by the excitation is detected.

Furthermore, it is natural that the magnetic poles of the permanent magnets 32 and 33 for applying a magnetic field to the magnetic fluid 21 may be either N pole or S pole.

FIG. 7 shows an example in which a control relay is used to control the time when the coil is excited. This is achieved by using a programmable controller (not shown).
