Title: Measuring method for thickness of double-layer plating
Inventor: KOGA TOSHIYUKI
IPC: G01B15/02
Filed: 1982-09-24
Abstract: PURPOSE:To measure accurately the thickness of intermediate plating by determining the background of fluorescent X-rays by using three kinds of standard samples, and by determining parameters of an equation in relation to the intensity of X-rays from an intermediate plating layer by using a standard sample. CONSTITUTION:A sample 3 is irradiated by an X-rays flux 2 emitted from an X-ray generating element 1, and the intensity of fluorescent X-rays R thus generated is measured by an X-ray detector 4, a preamplifier 5, a pulse-height analyzer 6 and an operating unit 7 and displayed in a display 8. The intensity (n) of the fluorescent X-rays from the intermediate plating of the sample 3 having a double-plating layer is given by an equation: n=(n00-n0)(1-exp(-mux)) exp(-mu'x'+n0(x')), where x and x' denote the thicknesses of intermediate plating and surface plating, n00 the intensity of saturation X-rays in relation to the very large thickness of the intermediate plating when there is no surface plating, and mu and mu' absorption coefficients of the intermediate plating and the surface plating. By determining background n0(x') by using three kinds of standard samples, and n00, mu and mu' by using a known standard sample, a value x can be measured accurately.

Abstract: PURPOSE:To detect leakage of reaction gas to a heating medium when the leakage occurs by a method wherein a detecting means to detect reaction gas leaking to a heating medium is situated in the heating medium in a chemical reactor. CONSTITUTION:Gas introduced through a reaction gas inflow and outflow port 2 to a chemical reactor 1 flows through a reaction gas flow passage 3 to a reaction material 7, wherein the gas is reacted to generate heat. The heat is transmitted through a heat transfer surface 8 and a fin 9 to a heating medium, e.g. water, flowing through a heating medium flow passage 6, and removed. Meanwhile, during reverse reaction, a reaction material 7 is heated through the heat transfer surface 8 and the fin 9 by mans of a heating medium flowing through the heating medium flow passage 6 to generate reaction gas. The reaction gas is guided through the inflow and outflow port 2 to the outside. When, during the reverse reaction, the reaction gas leaks past a part of the reaction gas flow passage 3 and the heat transfer surface 8 to the heating medium, in the case of the reaction gas being water soluble gas, the reaction gas is dissolved in water being the heating medium and flows in the direction of an outlet 5. The dissolved reaction gas is detected by means of a pH sensor 10, and leakage is detected by a signal transmitter 11.
