摘要： PURPOSE:To measure two kinds of element compsns. and coating thickness of a sample to be examined with one time of operation by passing the fluorescent X-rays from the sample to be examined separately through different filters of an automatic filter exchanger, then allowing said rays to enter an X-ray detector. CONSTITUTION:An X-ray tube 2 connected to an X-ray source 1 and a proportional counter 4 are installed diagonally above the sample 3 to be examined coated with an alloy and composite oxide contg. >=2 kinds of the components. The automatic filter exchanger 6 mounted with the different filters 5, 5' is installed between the sample 3 and the counter 4. The fluorescent X-rays from the sample 3 transmit through the filter 5 and enter the counter 4 by which the intensity of the fluorescent X-rays is detected. The exchanger 6 is actuated to exchange the filter 5 with the filter 5' and then measurement is made during this measurement. The intensities of two kinds of the fluorescent X-rays occurring in the filters 5, 5' are, therefore, detected. The intensities of both the fluorescent X-rays are inputted to a counter circuit 8 to be selected according to the kind of the filter to be used by a change-over mechanism 7 operating linked with the exchanger 6. The intensities of the fluorescent X-rays are thereby digitized. The values are sent to a data processing circuit 9. The compsn. and coating amt. of the constituting elements of the sample 3 are thus measured with a single operation.

摘要： PROBLEM TO BE SOLVED: To solve a problem that the performance of a tabular electroconductive diamond electrode is degraded due to the production of a carbonaceous substance having a non-diamond structure on one side, when the electrode is produced by using a CVD technique, and consequently to keep the performance of the electrode high by activating the electrode.
SOLUTION: This activating method includes bringing the surface of the electroconductive diamond electrode in contact with at least one substance selected from among excited hydrogen, excited oxygen and excited argon. The carbonaceous substance of the non-diamond structure produced on the surface contacts the excited gas, and is removed from the surface of the electrode.

摘要： PROBLEM TO BE SOLVED: To decrease the chlorine generating current efficiency in seawater in the case of producing an electrode by depositing the multiple oxide consisting of a noble metal oxide and a valve metal oxide on a base material by thermal decomposition to form a substrate and then electrodepositing manganese dioxide thereon. SOLUTION: Plate or expanded-mesh titanium is used as the electrode base material from the standpoint of corrosion resistance, and the oxide of a platinum metal, preferably iridium or ruthenium, and the oxide of such a valve metal as Ti, Ta and Zr are thermally decomposed and deposited to form a substrate layer. The composition of the substrate metal is controlled to noble metal/valve metal being 10 to 90 weight/90 to 10 weight, and manganese dioxide is electrodeposited on the substrate layer. At least one kind among the tungstate, molybdate and oxide of vanadium is preferably added to lower the current effect on generating chlorine. Further, after manganese dioxide is electrodeposited, the product is used as such in seawater without being dried.
