Abstract (en)
[origin: JPH03127498A] PURPOSE: To simply and securely eliminate resonant vibration by slightly modifying rotational speed at the time of the occurrence of resonance in a supporter of a rotary positive electrode motor. CONSTITUTION: When a vibration detector 5 detects the occurrence of resonance in a supporter of a rotary positive electrode motor 2 of a rotary positive electrode X-ray tube 1, a processor 6 controls a feeder circuit 4 to slightly modify rotational speed of the motor 2 up and down. This can simply and securely eliminate resonant vibration.
