Abstract: PROBLEM TO BE SOLVED: To provide a method capable of observing a sample to observe cut surface and structure of the sample in more details. SOLUTION: Wavelengths of a light emitted to a cut surface of a sample S are selected by first and second light wavelength selectors 2, 4, and imaged by a camera 5 while selecting the wavelength of the light incident on the camera 5 by a third light wavelength selector 6, and hence four image data responsive to the selectors are stored for one sample cut surface. Thus, the cut surface can be observed in more details by utilizing the four data obtained at the respective cut surfaces. A three-dimensional stereoscopic structure of the sample is accurately constructed from these data, and the structure can be accurately observed in detail.

Title: Vibration controller for rotating machine
Inventor: HASHIBA YUTAKA
IPC: H02P25/098
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To load damping force against the vibration of a rotating shaft at the critical speed of the rotating shaft, and operate a motor beyond the critical speed stably by controlling the current which flows through a damping control winding, so that the relation between a rotating field which the damping control winding generates and the direction of imbalance forms a specific expression. SOLUTION: A current flowing through a damping control winding 13 is controlled so that the expression of (p+1).β=pa0 +±/2+(ω+ωm)t is satisfied through a controller 16, where the imbalance directional angle of a rotor 2 is α, the pole position (angle) of a rotating field is β, the damping control winding 13 is 2(p+1) poles, and the frequency of the current to be supplied to the damping control winding 13 is (ω+ωm), and the phase difference from the pole position of the rotor 2 is set to pα+π/2. The magnetic attraction force acting on the rotor 2 acts as a damping force with respect to the centrifugal whirling of a shaft, and suppress its runout. As a result, it is thus possible to operate a motor beyond a critical speed.
