摘要： PROBLEM TO BE SOLVED: To detect salt water even if the air leaks on the water feed side, by connecting a plurality of decarbonation tanks via a piping, opening an inert gas feed piping at the liquid phase part and a discharge opening at the gas phase pat of each tank. SOLUTION: Each of decarbonation tanks 4-6 has an inert gas feed piping 8 and a discharge opening 9 opened at the liquid phase part and the gas phase part, respectively. A condensate is continuously sampled from a condenser 1 by a pump 2. The sampled water is passed through a cation exchange resin tower 3 to the decarbonation tank 4. A decarbonation inert gas is sent through the feed piping 8 to the liquid phase part of the decarbonation tank 4, where carbonic acid in the solution is removed and discharged along with carbonic dioxide gas through the discharge opening 9. The sampled water out from the decarbonation tank 4 is sent sequentially to the decarbonation tanks 5, 6, thereby, the remaining carbonic acid is completely removed. Thereafter, an electric conductivity of the sampled water is measured by an electric conductivity gauge 7. The sampled water is discharged outside. Even when air is mixed on the water feed side, the leak of salt water can be detected without being influenced by the carbonic dioxide gas.

摘要： PROBLEM TO BE SOLVED: To realize an oil leakage detecting device which can be applied to colorless oil without any influence of moisture and production of rust. SOLUTION: Since oil base components of a leakage oil considerably absorb light 9 of wavelength of 1.66-1.79μm, oil leakage can be detected at good sensibility by proving and forming a flow passage 3 of the leakage oil transmitting the light 9 of that wavelength between a light emitter 1 for emitting the light 9 and a light receiver 4 for receiving the light 9. In addition, since electric energy is unneeded on a light transmission part, a system having intrinsically safe property can be constituted and remote monitoring is made possible. Furthermore, since the light of the wavelength has a small transmission loss due to an optical fiber, the oil leakage of a long interval can be detected by connecting the light emitter and the light receiver by the optical fiber provided in the flow passage of the leakage oil and forming them.

摘要： PURPOSE: To detect leakage of sea water without being influenced of CO2 even when the air leaks to the water supply side or the vacuum is broken on the water supply side. CONSTITUTION: The leak monitor for salt water comprises a decarboxylation tank 5 having a gas phase part coupled with a cation-exchange resin tower 3 being fed with sample water and provided with an electric conductivity meter 4, a pump 6 coupled with the tank 5 for transporting the gas from the gas phase part, and a carbon dioxide suction tank 7 coupled with the pump 6 for supplying the gas and being supplied with the sample water. Since the influence of CO2 can be eliminated at the time of measuring the electric conductivity of sample water, leakage of sea water can be determined easily even when the air leaks to the water supply side. Furthermore, since the leakage can be dealt with quickly, leakage of sea water can be monitored sufficiently even when the vacuum is broken on the water supply side.

摘要： PURPOSE:To measure a thin-film sample with the decreased penetration depth of X-rays to the sample by setting the angle between an incident X-ray and the sample surface and the angle between a diffracted X-ray and the sample surface at low angles and scanning scattering slits and solar slits in parallel with the sample surface. CONSTITUTION:The incident X-ray 9 generated from an X-ray tube bulb 1 is projected through the incident side solar slit 2 and the divergent slit 3 to the surface of the sample 4. The diffracted X-ray 10 diffracted by the surface of the sample 4 is further passed through the scattering slit 5 and the photodetecting side solar slit 6 and is reflected by a monochrometer 7 to arrive at an X-ray detector 8. The angle gamma between the X-ray 9 from the bulb 1 and the ample 4 surface and the angle delta between the X-ray 10 and the sample 4 surface are fixed at the small angles in order to decrease the penetration depth of the X-ray 9 to the sample 4. The slit 5, the slit 6 and the meter 7 are scanned in the direction parallel with the sample 4 surface. The measurement of the sample 4 is thereby enabled with the decreased penetration depth of the X-ray 9 to the sample 4.

摘要： PURPOSE:To facilitate smooth and quick withdrawal of each classified fraction from a wet type sieve classifier by providing a branch pipe connected to a valve to an upper side surface of each vessel of classified fraction and providing also a filter to each end of the branch pipe. CONSTITUTION:In a wet type sieve classifier which classifies a sample dispersed in a dispersing medium with several stages of sieve vessel 2-6 having a mesh of the sieve different to each other, branch pipes 2'-6' connected to valves 25-29 are provided to the upper side surface of the sieve vessels, and each one filter 30-34 is fitted to the end of each branch pipe. Thus, classification procedure is executed similarly as the conventional procedure by closing the valves 25-29 completely. When a classified fraction in each sieve vessel is to be withdrawn after finishing classification, the dispering medium is flowed from below oppositely to the procedure in the classification stage to allow the classified fraction in each sieve vessel and conduct the fraction to each corresponding filter. Thus, the withdrawal of classified fraction is executed easily and in a short time.

摘要： PROBLEM TO BE SOLVED: To provide a measuring apparatus for the concentration of sulfur trioxide in an exhaust gas by which the concentration of the SO3 in the exhaust gas can be measured continuously and simply. SOLUTION: By a suction pump 15, an exhaust gas is introduced into a gas cell 21 via a collection pipe 11 which is inserted into an exhaust-gas flow passage 101. Both ends of the gas cell are formed as windows through which infrared rays are transmitted, The gas cell itself is arranged in the optical path of a Fourier-transform infrared spectroscope 20. Infrared rays which transmit the exhaust gas are converted into an electric signal by a detector 206 so as to be Fourier-transformed by an FFT 208, and the absorbance of SO3 is measured. Since the absorbance and the concentration of the SO3 are in a nearly proportional relationship, the concentration of the SO3 is decided on the basis of the absorbance of the SO3. In addition, when the optical path of the spectroscope is constituted inside a probe which is inserted into the exhaust- gas flow passage, the concentration of the SO3 can be measured without deriving the exhaust gas from the exhaust-gas flow passage.
