IPC: G01N21/31
Filed: 1981-08-29
Abstract: PURPOSE:To make possible measurement of integral value of an absorbance peak by separating a background absorption peak and a scattering peak, by integrating only the absorbance from starting time to finishing time of the real absorbance. CONSTITUTION:A line spectrum of an element to be measured is discharged from a hollow cathode lamp and its energy is absorbed by a resonance line of a sample in a high temperature atomizing part and the line spectrum other than the resonance line is passed through as it is. Further, only the light near the resonance line from a spectroscope is made incident to a detector and only the magnitude of the resonance line decreased by the absorption of the element in the sample is detected. An output of this detector is added to a high speed peak-shaped reader consisting of a computer and an A/D converter and the value of absorbance of atomizing time at every time is read and then, is stored in a memory. Then, the integral value of an absorbance peak is found separating from the absorbance peak of absorption and scattering of molecules by integrating only the absorbance from starting to finishing time of the real value of the atomic absorbance.

Abstract: PROBLEM TO BE SOLVED: To provide a high power electron gun by providing a column-like spacer made of a high resistance conductive material in the circumferential wall of a beam passing hole and constituting opposed conductive films as a grid and a beam passing hole as an electron beam passing hole. SOLUTION: To assemble an electron gun, while a spacer 2 being fitted in a recessed part of, for example, a first electrode 31 and a projected part of a second electrode 32 being butted into the spacer 2 and pressured, electron gun parts such as the electrodes 31, 32, a third grid G3 to a fifth grid G5 are respectively positioned in a positioning jig. Bead glass BG is melted and respective pins CP for installation are rooted in the bead glass to complete the assembly. Since the first and the second grids G1 and G2 are conductive films 5, 6 formed in the upper face and the lower faces of a minor axial cylindrical type ceramic, the diameter difference between the grids is not caused and grids are excellently paralleled. As a result, strain of an electron beam locus can be suppressed and images with high resolution can be obtained.
