摘要： PROBLEM TO BE SOLVED: To provide a propulsion device and a flying object propulsion device that use space drive type magnetic fluid circulation whereby accelerations as high as several tens of G and quasi-light velocity as the final attainable velocity can be obtained with a relatively low magnetic field. SOLUTION: An annular tube 1 confines a magnetic fluid 6 which rotates rightward (clockwise as seen from above). The annular tube 2 vertically overlaps the annular tube 1 to confine a magnetic fluid 7 which rotates leftward (counterclockwise as seen from above). Pairs of electromagnets 3a-3h sandwich the annular tubes 1, 2 and apply the polarities of a magnetic field alternately thereto. A laser beam source irradiates laser beams to the magnetic fluids 6, 7 of the annular tubes 1, 2 between the alternately installed electromagnets. A drive pump 8 causes the magnetic fluids 6, 7 to circulate in opposite directions.

摘要： PROBLEM TO BE SOLVED: To provide a transformer which also can be built into an electronic control system as a functional element by enabling precision voltage setting not through intermittent swathing, wherein a tap is used but through changing transformation ratio continuously in various transformers. SOLUTION: A transformer which is able to change transformation ratio continuously can be obtained by constituting it mainly of an annular primary coil 1, formed of a conductive magnetism and a conductive secondary coil 2 wound on a circumference of a primary coil toroidally, adding a magnetic field generation means 4 and adjusting the magnetic field of the magnetic field generation means. First, AC current is applied to a primary coil of a conductive magnetism of a transformer main constitution 3. Then, voltage is induced to a secondary coil wound toroidally on the annular coil by magnetic field generated from a primary coil. In this process, the value of output voltage/current is decided by a distance from the transformer main constitution 3 of the magnetic field generation means 4. Since the position of the magnetic field generation means 4 can be moved continuously, the transformation ratio of a secondary side voltage can also be changed continuously.
