Title: Quantitative determination of hydrogen peroxide
Inventor: HANADA TOSHIROU
IPC: G01N33/50
Filed: 1984-04-10
Abstract: PURPOSE:To enable quantitative determination with high sensitivity from a microtrace quantity to a high concn. without the need for dilution and to determine quantitatively the H2O2 formed by an enzyme reaction as well in the stage of determining quantitatively the H2O2 with a triphenyl methane deriv. as a color developing component by adding an azide to a sample to adjust color sensitibity. CONSTITUTION:The triphenyl methane deriv. expressed by the formula [R1, R2, R3, R4 are lower alkyl, X1, X2 are -O(CH2)nSO3M1, M1 is H, alkali metallic ion or NH4<+>, n is 2-4 or one is -O(CH2)nSO3M1 or SO3M2, M2 is the same as M1 and the other is H] is added as a color developing component together with an azide, particulary sodium azide at about 0.01-0.5% into a color developing reagent liquid. Although there is a need for diluting the sample in the stage of using only the triphenyl methane deriv., the measurement with good linearity to 100mg/l with high sensitivity from a microtrace quantity is made possible without the need for such dilution. The exact measurement of the component such as chloesterol in a bio-fluid is made possible by generating the H2O2 by the enzyme reaction and measuring the H2O2.

Abstract: PROBLEM TO BE SOLVED: To form a silicide layer, having the same thickness and sheet resistance of even with a fine region which is poor in metal coverage on a semiconductor substrate as those of a wide region which is satisfactory in coverage. SOLUTION: Source/drain diffused layers 16, 17 are formed, a thin oxide film 18 is formed thereon, and a Co film 19 is deposited through the directional sputtering with a substrate being heated to form intermediate Co-Si and Co-Si-O layers 20, 21 thermally unstable in composition.

Title: Proximity field scanning optical microscope
Inventor: AOSHIMA SHINICHIRO
IPC: G01N37/00
Filed: 1991-04-05
Abstract: PURPOSE:To lessen the influence of background light and to detect the probe light from a light source with good S/N so as to improve a resolving power by forming the probe light into impulsive light and operating a photodetector in synchronization therewith. CONSTITUTION:The light source 30 generates the probe light with which a sample 16 is irradiated. An optical probe 28 has a pinhole at its tip and selectively supplies the probe light to the sample 16 through this pinhole. The photodetector 44 detects the exit light emitted from the sample 16 and converts this light to an electric signal. The light source 30 generates the probe light of impulsively changing intensities. The photodetector 44 detects the exit light in synchronization with the time when the probe light changing impulsively increases. The detector converts this light to the electric signal. The noise converted to the electric signal is, therefore, decreased even while the impulsively changing probe light decreases. The measurement is eventually made with the good S/N. Since the measurement is possible in spite of a small pinhole diameter, the resolving power of the proximity field scanning optical microscope is improved.
