Abstract: PURPOSE:To make it possible to detect the thickness of a metal oxide film, by applying constant current pulses through an electrolyte solution with the metallic material as an anode or cathode, and measuring the rise time or attenuation time of the polarization potential of the anode or cathode. CONSTITUTION:A material 5 from which contamination is to be removed is immersed in an electrolyte cell 4.

Abstract: PURPOSE:To absorb vibration by installing an inside housing which encloses a bearing holder made of magnetic material and on which an electromagnet is installed and controlling the current-carrying to the electromagnet by the movement of the bearing holder and allowing the viscous fluid to be interposed between the inside and outside housings. CONSTITUTION:A roller bearing 3 is supported by a bearing holder 19 made of magnetic material, and an inside housing 25 on which electromagnets 22a-22d are installed is installed, surrounding the bearing holder 19. The electromagnets 22a-22d are allowed to conduct by the voltage corresponding to the electromagnets 22a-22d on the basis of the detection signal of a sensor for detecting the movement of the bearing holder. A bottom pad 26 is inserted into the recessed part 28 between the inside housing 25 and an outside housing 27, and lubricating oil (viscous fluid) is supplied from an oil reservoir 30. Vibration is suppressed by the pulling by an electromagnet in the reverse direction to the displacement by vibration.
