Embodiments of the present subject mater compress the air stream by accelerating charged particles with a moving magnetic field, where the magnetic field has a velocity perpendicular to its flux lines. The increased velocity of the charged particles increases the statistical mean particle velocity and thereby increases the pressure in the air stream. The compressed air stream is then heated and expanded through a second magnetic field. The expansion of the air stream substantially increases the velocity of the air stream and the charged particles therein. The interaction of the high velocity charged particles and the magnetic field imparts a force perpendicular to the flux lines, this force powers the movement of the magnetic field. 1.

Decane (C10H22) is sprayed as a mist from spray nozzles toward a rotor blade via a supply pipe and communication passages. Since decane has a boiling point of 174° C. at atmospheric pressure, the decane is a liquid at normal temperature and normal pressure. On the other hand, the pressure inside a turbomolecular pump is in a substantially vacuum state of about 100 Pa, and the boiling point of decane at this pressure is 14° C. Thus, although the pressure is high and the decane is in a liquid state until the decane is sprayed, when the decane adheres to surfaces of the rotor blades and the temperature of the decane rises, the decane vaporizes. At this moment, since the amount of heat of the rotor blades is consumed as heat of vaporization, the rotor blades can be cooled. 1. A vacuum pump , comprising:an outer cylinder;a rotor blade contained in the outer cylinder;a rotor shaft attached to the rotor blade;a magnetic bearing supporting the rotor shaft in a levitated manner in the air;a rotary drive means for driving the rotor shaft to rotate;a stator disposed between the rotor blade and the rotor shaft; andan injection port disposed on the stator so as to face at least either the rotor blade or the rotor shaft,wherein liquid is ejected from the injection port to cool at least either the rotor blade or the rotor shaft with the liquid.2.
