摘要： A system for supplying power to automotive parts having a rotary component is disclosed, in which a pair of circular coils (30, 32) are in opposed relation to each other around a rotary shaft (4) of a rotor (15, 19). One coil (32) is fixed on rotor side, and the other coil (30) is fixed on stator side, thereby forming a DC/DC converter. Taking advantage of the fact that the rate of magnetic coupling between the coils is constant against the rotation of the coil on rotor side, stable power is supplied efficiently to the devices on rotor side in contactless fashion.

摘要： Ignition system for internal combustion engine in which combustion chambers in an internal combustion engine are shaped in such a manner that a microwave resonance easily causes a plasma discharge, microwaves are supplied from a microwave oscillator (12) through respective coaxial cables to all the combustion chambers (3, 9) so that the combustion chambers resonate whenever the microwave power is injected, or so that when the combustion chambers reaches a resonatable condition, is the microwave power injected into the combustion chambers from the microwave oscillator (12); thereby causing plasma discharge to occur in the combustion chambers (3, 9).
