Title: Fluorescent x-ray analyzing method
Inventor: NAKATANI TAKEHIKO
IPC: G01N23/223
Filed: 1987-12-15
Abstract: PURPOSE:To execute the quantitative analysis of a mixed sample containing both a heavy element and a light element with high accuracy by switching a target of a dual target X-ray tube by a prescribed time division, radiating generated primary X rays to the sample and detecting obtained fluorescent X rays. CONSTITUTION:A sample 10 is set, a filament 4a of a dual target X-ray tube is brought to electric conduction by a switching circuit 8, and primary X rays from a W target 2a are radiated to the sample 10. Radiated fluorescent X rays are detected by a detector 14, and its detecting signal is counted only for a T1 period through an amplifier 14, a crest analyzer 16 and an AND gate 20. After the T1 period has elapsed, the AND gate 20 is closed and a filament 4b is brought to electric conduction by the switching circuit 8, primary X rays from an Rh target 2b are radiated to the sample 10, and also, the AND gate 20 is opened, and only for a T2 period, a detecting signal of the fluorescent X rays is counted and the AND gate 20 is closed. In that case, an analysis condition of a spectral crystal 12 is kept constant. Subsequently, each count value before and after switching the targets 2a, 2b is integrated, and it becomes a count value in the integral time T.

Filed: 1993-12-16
Abstract: PURPOSE:To lessen the signal abnormality generated in a level shifter by specifying the size ratios of transistors connected to a high-voltage power source side of the level shfiter and the transistors (TRs) connected to a low-voltage power source side to suitable size ratios at which the signal abnormality hardly arises. CONSTITUTION:The signal abnormality is prevented by size setting of the TRs of the level shifter 11. Namely, the TFT sizes are so set that the on-resistance of the N channel thin-film transistors (TFTs) 13, 15 is not higher than the on-resistance of the P channel TFTs 14, 16. For example, the gate width of the N channel TFTs 13, 15 is larger than the gate width of the P channel TFTs 14, 16 if the gate length of the N channel TFTs 13, 15 and the gate length of the P channel TFTs 14, 16 are the same. The gate length of the N channel TFTs 13, 15 is made smaller than the gate length of the P channel TFTs 14, 16 if the gate widths of the P channel TFTs 14, 16 and the N channel TFTs 13, 15 are the same.
