    摘要: A turbo molecular pump includes a magnetic bearing system which includes a rotor having an impeller connected to a shaft and a motor. A stator is positioned between the shaft and the impeller. Radial magnetic bearings, an active axial magnetic bearing and emergency bearings are each provided between the rotor and the stator. The radial magnetic bearings include passive magnetic bearings provided on the rotor and the stator respectively. The axial magnet bearing is disposed in the vicinity where the impeller is connected to the shaft. The emergency bearings are disposed on a low vacuum side with one emergency bearing being positioned near the axial magnetic bearing. A diameter of the shaft is made smaller than an inside diameter of the emergency bearing near the axial magnetic bearing. By this arrangement, only one control axis is necessary for controlling the position of the rotor. Disassembling of the shaft and impeller is easy and contamination of the high vacuum side can be prevented.

    摘要: A combustor for waste gas treatment having a flame stabilizing zone surrounded by a peripheral wall and closed with a bottom wall. The flame stabilizing zone is provided to face a combustion chamber. Burner ports for auxiliary combustible gas are provided in the peripheral wall to inject an auxiliary combustible gas into the flame stabilizing zone so as to produce swirling flows. Burner ports for waste gas are provided in the bottom wall to inject a gas into the flame stabilizing zone.

    摘要: A radial magnetic bearing apparatus suspends a rotating shaft and stably operates at a level exceeding a bending intrinsic vibration value of the rotating shaft by controlling magnetic forces generated by control coils wound around control magnetic poles. Grooves are provided on the surface of each control magnetic pole facing the rotating shaft, and sensor coils are wound to pass through the grooves in order to detect the position of the rotating shaft in the radial direction. A part of each control magnetic pole may be used as magnetic poles of an inductance-type displacement sensor.
