Title: Eccentric vacuum pump
Inventor: KONDO KOJI
IPC: F04C25/02
Filed: 1995-01-25
Abstract: PURPOSE: To provide an eccentric type vacuum pump with no necessity for strictly performing centering a pair of housings. CONSTITUTION: Housings 3, 5 are connected to each other, to form a pump chamber 9. A shaft 13, integrally rotated with a rotor 11, is eccentrically arranged in the pump chamber 9, and one end 13a of the shaft is extended to the vicinity of an internal wall surface of the housing 5, to form a free end. The other end 13b of the shaft 13 is supported rotatably further not feucturatably in a vertical direction of the shaft in the housing 3 through a bearing mechanism 15. Since a part of supporting the shaft 13 is not provided in the housing 5, even when the housings 3, 5 are connected with centers thereof a little displaced, no distortion is applied to the shaft 13. Consequently, necessity for strictly performing centering each housing 3, 5 is eliminated.

IPC: G01B11/06
Filed: 1979-02-02
Abstract: PURPOSE: To realize the non-destructive and high-accuracy measurement of the film thickness through the fixed calculation formula by changing continuously the wavelength of the monochrome light entering the subject to be measured and based on the wavelength and the refractive index of the extreme value of the interference luminous intensity of the reflected light obtained from both surfaces of the measured subject.  
     CONSTITUTION: Using the popularly known thin-film interference light measuring device, the radiant light given from tungsten lamp 1 featuring the continuous spectrum is irradiated to thin film 3 to be measured, and the reference light from both surfaces are supplied to the X axis of XY recorder 8 via potentiometer 6 and then to the Y axis via detector 7. Thus the chart of the waveform is recorded to recorder 8. Maximum value λ j  of signal 10 indicates the position where the reflected light  from both surfaces are strengthened mutually, and the minimum value is the position where the light are weakened each other respectively. When the wavelength  which gives the extreme value of No.j is referred to as λ j , film thickness h can be  obtained by Eq. 1. Thus the calculation is based on all extreme value (including  the maximum and minimum value) within the range of the measuring wavelength.  As a result, the accuracy of the measurements can be increased.

Abstract: PURPOSE:To appropriately control the slagging condition by obtaining the variations in the slagging condition in the progress of blowing with a specified equation, and adjusting the blowing condition at the time of blowing desiliconized and dephosphorized molten iron in a converter. CONSTITUTION:The relation (transition) shown by the equation between the non-decarburizing oxygen efficiency (etax) and the standardized slagging condition is previously obtained as the model variation, when the desiliconized and dephosphorized molten iron is blown in a converter. In the equation, K is a coefficient determined by the blowing condition, etc. The non-decarburizing oxygen efficiency (etax) is then continuously or intermittently measured by the equation in the actual operation to obtain the variation in the slagging condition from its transition, and the value is compared with the model variation to correct the variation in the direction cancelling the difference. By this method, the slagging condition can be appropriately maintained, and the generation of slopping and spitting is prevented.
