Abstract: PURPOSE:To easily and quickly insert/remove a large size rotor from a stator using a comparatively simple device by constituting a carriage so that a horizon tal driving body provided connects to the flange part of a rotor and moves in the axial direction by the rotation of a screw shaft. CONSTITUTION:A carriage 6 is moved and made to be adjacent to one end of a motor, and a fine adjustment in the vertical and horizontal directions is performed so that the axis of the flange part of a horizontal driving body 10 and that of a rotary shaft 13 coincide with each other. For that purpose, a vertical motion mechanism 4 is vertically moved by the fine adjustment performed hydraulically or manually, and a wheel 2 is moved in the horizontal direction. Then, one end of the carriage 6 is made to abut the end of the motor, and locked there. Next, a driving mechanism 7 is actuated to rotate a screw shaft 8 moving the horizontal driving body 10 rightward. When a rotor 9 is moved rightward, a shoe 16 is also provided on a supporting surface 5 to slide the rotor 9 on the supporting surface 5. Then, the rotor 9 is completely pulled out and placed on the supporting surface 5, where its inspection and maintenance are carried out.

Filed: 1991-09-26
Abstract: PURPOSE:To obtain an accurate measurement value without performing a troublesome operation such as overhaul by detecting contamination on a wall surface within a cell with a certain measure and then washing an inner-wall surface automatically. CONSTITUTION:Laser beam is cast into a cell 5 while only a medium liquid is circulated at a clean cell 5 before measurement, outputs of detectors 10 and 11 are taken into a computer 14 as blank values, and then an output value of the detector 10 for forward diffraction/scattering light is memorized as a reference value.
