摘要： PROBLEM TO BE SOLVED: To obtain a non-contact generation system, by rectifying the alternating-current electromotive force of a generator rotated at high speed using a frequency conversion mechanism which causes fluctuation in magnetic field and accelerates mechanical displacement, and charging a secondary power supply with it. SOLUTION: In a direct-current/orthogonal-current magnetic field generator placed outside a living body, a current is passed through a two-phase coil each phase of which is provided with a low-frequency alternating-current power supply, and low-frequency a rotating magnetic field is produced. A large gear 8 to which a permanent magnet 7 is bonded is placed in a generation unit 6 with its teeth engaged with those of a small gear 9. Since the rotary shaft 2 of a generator 10 is identical with the rotary shaft 2 of the small gear 9, the generator 10 is also rotated at a speed approx. 100 times that of the magnet 7 and the large gear 8. The generator 10 is provided therein with permanent magnets which rotate in synchronization with the rotary shaft 2 and coils located in proximity to the permanent magnets. At the result of the rotation of the permanent magnets, the magnetic flux penetrating the coils is varied and alternating-current electromotive force is produced at coil ends. The alternating- current electromotive force is converted into a direct current through a rectifying circuit 11, and then charged into a secondary power supply 12. A pace maker as a processor 13 is driven using the power.
