摘要： PURPOSE:To improve durability of a furnace material and to produce a titled alloy in a rare gaseous atmosphere with less contamination from the furnace material by using MgO clinker as the inside wall material of a high frequency induction melting furnace and sintering the same by a molten low-melting Fe-Ti alloy. CONSTITUTION:At least the part of the inside wall of a high-frequency induction melting furnace where the wall contacts a molten metal is constitued by compacting a mixture composed of, for example, magnesia clinker and a water glass liquid in said part and drying the same. A low-melting Fe-Ti alloy is melted by using such furnace to sinter the furnace wall and after the end of the sintering, said alloy is charged into a casting mold and is thus discharged from the furnace. Iron scrap is charged into the melting furnace subjected to said treatment while rare gas such as gaseous Ar is blown therein to melt the scrap then the Ti sponge corresponding to the target compsn. is successively charged thereon and is melted so that the base material is thoroughly melted. After the molten metal is held at the m.p. or above for a while, the molten metal is charged into the casting mold replaced with the rare gas and the Fe-Ti alloy ingot for occluding hydrogen is produced.

摘要： PURPOSE:To directly measure the concentration of sulfur in molten metal simply and quickly, by measuring the electromotive force through the use of solid electrolyte. CONSTITUTION:The solid electrolyte 1 having high temperature stability withstanding high temperature of molten metal and having good sulfur ion conductivity such as Y2O2S, Eu2O2S, Gd2O2S, Tb2O2S, and Ce2O2S, oxysulfide monomer or mixed sintered body of a plurality of rare earth elements, is fixed to the tip of the alumina protective tube 4, and the sulfur compound 2 for standard electrode is provided in contact with the solid electrolyte internally, and it is connected to the high impedance potentiometer 12 connected to the external electrode molybdenum rod 5 via the molybdenum rod 3 and the lead wire 10. Thus, when the detection terminal is immersed in molten metal containing sulfur, the electromotive force produced across the solid electrolyte 1 is measured at the high impedance potentiometer 12 and the concentration of sulfur can be detected from the measured electromotive force.

摘要： PURPOSE:To store grain, especially rice grain such as polished rice, unpolished rice, etc., in high efficiency, by controlling the time for the transferring and charging of the grain into a storage vessel, thereby preabsorbing CO2 gas to the grain and reducing the absorption of CO2 gas after sealing the grain in the vessel. CONSTITUTION:CO2 gas is introduced into a storage vessel containing grain and a means for transferring the grain, and the air in the vessel, etc. is substituted with CO2 gas. The flow rate of the CO2 gas is controlled according to the measured concentration of CO2 gas in a hopper. The rate of grain transfer is also controlled to effect the preabsorption of the grain with CO2 gas in an amount determined by the initial CO2 pressure immediately after charging in the storage vessel and the equilibrium CO2 pressure. For example, grain such as rice is stored in a hopper 1, and transferred to a storage vessel 4 with a transferring means 3 furnished with a flow controller 2. The flow rate and pressure of CO2 gas are controlled with a gas flow rate controller 6, and the gas is introduced into the vessel 4 through a pipe 7.

摘要： PURPOSE:To increase the accuracy of quantitative analysis by decreasing the value for blank test, by introducing test piece to the extraction vessel degased with high temperature heating and heating the test piece only at a high temperature. CONSTITUTION:The extraction vessel 4 of quartz exhausted with the ion pump 9 is heated at about 1000 deg.C before the introduction of test piece with the electric furnace 6-1, to discharge the absorbed gas of the vessel itself. After exhausting the test piece 1 in the pre-exhaust chamber 2, it is placed on the quartz made holding stand in the vessel 4 through the gate valve 3, and the electric furnace 6-1 is selected to the spot heater 6-2 such as infrared ray heating furnace or laser light. With the heater 6-2 controlled with the thermocouple 5 and the temperature control unit 7, only the test piece 1 is heated to a high temperature without heating the external wall of the vessel 4 to discharge hydrogen, which is entered to the hydrogen analysis meter 11 through the needle valve 10. Further, the signal from the analysis meter 11 and the unit 7 enters the recorder 14 to display the amount of hydrogen and temperature. Since the test value for blank test is decreased with this two stage heating system, the accuracy of quantitative analysis for fine amount of hydrogen can especially be increased.

摘要： PURPOSE:To measure the component for measurement accurately, by eliminating interference light other than Raman scattered light, measuring the total Raman scattered light intensity and the Raman scattered light intensity of the component for measurement, and determining the ratio of the two. CONSTITUTION:A laser beam leaving a laser beam source 1 radiates a specimen 2, from which scattered light and reflected light are generated, which, then, enter a sharp cut filter 5, and only Raman scattered light is transmitted. The Raman scattered light enters a mirror of a known transmittance, which reflects a majority thereof while transmitting only a part, so that a part of the Raman scattered light is led into a photo detector 7 while the rest is reflected and reaches a detector 10 after spectral analysis at a mirror 8 and a diffraction grating 9. Signals from detectors 7 and 10 are fed into a division circuit 11, and the Raman scattered light intensity A of the component being measured as measured in the detector 10 is divided by the total Raman scattered light intensity B as measured in the detector 7, and the concentration of the component being measured is calculated in a multiplication circuit 12.

摘要： PURPOSE:To provide a titled metallic material which can occlude or release stably hydrogen at a high density by incorporating a specific compsn. amt. of Ti and Mischmetal (Mm) to Fe. CONSTITUTION:A Ti-Fe-Mm metallic material for occluding hydrogen is obtd. by incorporating 0.90-1.05 Ti by atom ratio and 0.015-0.1 Mm to Fe, and incorporating further S at a ratio of 0.004-0.04 atom ratio with respect to Ti+ Mm thereto. Said material has excellent activation performance, plateau characteristic and amt. of hydrogen to be occluded and is produceable of inexpensive raw materials. The activation performance of said alloy is improved by incorporating Mm particularly at a concn. as high as about 2-12wt% in said alloy so that the easy activation is made possible at room temp. A mixture of Ce group metals which are rare earth elements particularly contg. much Ce is more preferable as the above-mentioned Mm. It is possible to form sulfide and to improve further the performance by adding an adequate amt. of S to the alloy.

摘要： PURPOSE:To activate readily a hydrogen-occluded metal within a short period, by treating the hydrogen-occluded metal with a low temperature or high temperature plasma containing H. CONSTITUTION:Electric waves from an oscillator 1 of about 2,450MHz are introduced through a metal antenna 2 to radiate microwaves through a porcelain tube 3 into a rotary drum type plasma oscillator 4. A gas mixture containing about 50% Ar and about 50% H2 is introduced through a gas inlet-outlet tube 5 at one atmosphere and a constant flow rate of about 500cc/min into the oscillator 4 to produce a low temperature plasma. By rotating the oscillator 4, a hydrogen-occluded metal powder 6 such as a TiF alloy or the like in the oscillator 4 becomes in contact with the plasma, H dissociated from H2 in the hydrogen plasma reduces the oxides on the metal surfaces, and further the H is diffused and occluded into the metal to activate the metal. The activated metal powder is immediately taken out through a takeout valve 7 into a storing vessel 8 the inside atmosphere of which is replaced with H2 so that it wound not become in contact with the atmosphere to be deactivated.
