Filed: 1993-05-18
Abstract: PURPOSE:To make an accurate quantitative analysis by providing an acceleration voltage selecting means to produce electron beams. CONSTITUTION:An electron beam from an electron gun 12 is radiated on a sample with the unknown density at a specific acceleration voltage, beam current, and beam diameter. After a specific X ray discharged from the sample is detected by a detector 14, the intensity is measured by an X-ray measuring means 31, and the result is stored in the second memory 32. Depending on the data of a standard sample and the unknown sample, an operation of quantitative analysis is carried out. The intensities of the characteristic X ray of the standard sample and the unknown sample are read at each analized element from the memory 32, so as to calculate the weight and the density of each element. After this operation of quantitative analysis is over, a correction calculation is carried out, so as to obtain the quantitative values. As this quantitative analysis and the correction method, a ZAF method and some other methods are avalable, and a desired quantitative analysis and a desired correction method can be selected in this invention. By such a way, the analyzing area in the depth direction of the sample can be selected, and an accurate quantitative analysis at the same analyzing depth can be made of a different sort of element to be analyzed.

Abstract: PURPOSE:To correct variance in sensitivity among picture elements of a photodetector and improve the S/N of a spectrum, and to enable a highly accurate spectral analysis by moving an interference image which is formed on the photodetector relatively in the array direction of the picture elements. CONSTITUTION:When the variance in sensitivity among the individual picture elements of the photodetector 20 is corrected, light to be measured as an object of the spectral analysis is made incident on a beam splitter 11 in sensitivity correction mode and optical glass 30 is rotated as shown by an arrow to move the interference image on the photodetector 20 in the array direction of the picture elements, thereby realizing a state equivalent to the irradiation of the respective picture elements with nearly equal-intensity light. The movement distance at this time is a distance by which the interference image moves from the center to the right and left by about 1/20 as many as all the picture elements in the array direction. The output of the photodetector 20 contains random noise components extremely slightly, so the mean value of photodetected values of the respective picture elements is found to remove the influence of the noise components effectively.

Abstract: PURPOSE:To improve the smoothness of a plane by setting the coefficient of linear expansion of a resin layer lower at the inner layer part than at the surface layer part thereby suppressing the irregularities on the surface. CONSTITUTION:Thickness t2 of resin layer at the inner layer part R2 is set equal to that of an electronic component 4 and the thicknesses t1a, t1b at the surface layer parts R1a, R1b, are set equal to that of the resin layer at the parts above and below the electronic component 4. Total thickness of a long fiber reinforced resin layer R is equal to that of an in-molded item. On the other hand, the coefficient of linear expansion in the direction of thickness is highest(3X10<-4>/ deg.C) at the surface layers R1a, R1b, of the resin layer R, is equal to 1X10<-4>/ deg.C at the inner layer part R2 of the resin layer R, and is lowest (0.5X10<-4>/ deg.C) at the electronic component 4.
