    摘要: A correction curve (FIG. 19) is prepared by plotting 12CO2 concentrations and 13CO2/12CO2 concentration ratios which are determined on the basis of a calibration curve and 13CO2 and 12CO2 absorbances of gaseous samples having the same 13CO2/12CO2 concentration ratio but known different 12CO2 concentrations. A gaseous test sample containing 13CO2 and 12CO2 as component gases is introduced into a cell, and spectrometrically measured. A 12CO2 concentration of the gaseous test sample is determined by way of the spectrometric measurement. A concentration ratio correction value is obtained on the basis of the correction curve and the 12CO2 concentration of the gaseous test sample thus determined. A measured 13CO2/12CO2 concentration ratio is divided by the concentration ratio correction value thus obtained for correction of the 13CO2/12CO2 concentration ratio. Thus, the measurement accuracy of the concentration ratios of the component gases can be improved.

    摘要: A rotary stand (11) having a half-mirror (8) and a photodetector (10) mounted thereon, is continuously rotated around a first rotary shaft (A) passing through a sample (S), and set to a predetermined scattering angle. Simultaneously, a rotary reflecting mirror (7) is rotated at a predetermined angle to direct a reference li8ght (LR) to the half-mirror (8) at all times. The half-mirror (8) is also rotated at its own axis at a predetermined angle so that the direction of a scattering light (LS) at the light emitting side of the half-mirror (8) is identical with the direction of the reference lilght (LR). Accordingly, the reference light may be composed with the scattered light at an arbitrary scattering angle, enabling observation of the Doppler shift in the scattered light direction (FIG. 1).

    摘要: A refrigerant compressor for automobile air-conditioning system is disclosed. The compressor comprises a front end plate member and a cylindrical casing attached to an end surface of the front end plate member. A polygonal shaped portion is formed on the outer peripheral surface of the front end plate member and a plurality of projections are formed on an opposite end of the housing from the polygonal shaped portion. The end surfaces of the projections are aligned on the same plane with each end surface of polygonal shaped portion. The end surfaces of the projections and the polygonal shaped portion have tapped holes for attaching mounting brackets. Therefore, a variety of suitable mounting arrangements can be used to mount the compressor and the mounting angle of the compressor can be adjusted.
