摘要： PROBLEM TO BE SOLVED: To provide an apparatus for synthesizing polymers from a raw material in a molten state by which high quality polymers can be obtained.
SOLUTION: The operation procedure of this synthesizing apparatus is as follows. A lactide fed from a lactide feeding apparatus 1 is heated to be molten in a lactide melting apparatus 2 and to the molten lactide, a catalyst is added in a catalyst feeding apparatus 3. The molten lactide is fed through a lactide feeding apparatus 4 to a horizontal reaction vessel 5 and in the vessel 5, a polymerization reaction of the lactide is progressed by a head pressure difference while the lactide flows. The reaction liquid discharged from the vessel 5 is fed into an upper part of a vertical reaction vessel 6 and flows through the inside thereof by the gravity to thereby progress the polymerization reaction. Thereafter the reaction liquid is transported into a remained lactide removing apparatus 7 to remove unreacted lactide and is discharged out of the apparatus 7.

摘要： PROBLEM TO BE SOLVED: To reduce the water concentration in a lactide in a lactide synthesis apparatus or process. SOLUTION: After a lactic acid oligomer discharge valve 10 is closed, lactic acid is transferred to a lactic acid condensation apparatus 2. The lactic acid is concentrated and condensed by heating in a vacuum, and the formed water is evaporated. Lactic acid, a lactic acid oligomer, and lactide are removed from or returned to the formed gas by means of a condensation apparatus 11. The water concentration of the gas is measured with a pressure measurement device 12. After confirming that the water concentration is not higher than a specified value, the lactic acid oligomer discharge valve 10 is opened to transfer the lactic acid oligomer. The oligomer is depolymerized to form gaseous lactide, which is then condensed and recovered. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce the amount of Na ions and Cl ions remaining in solution containing univalent ions and polyvalent ions. SOLUTION: Solution 1 to be separated which is wet oxidizing treated urine contains univalent ions such as Na, K, and Cl and polyvalent ions such as Ca, Mg, SO4 , and PO4 as mineral components. The solution to be separated 1 is mixed with solid or aq. solution of KCl 2 in a mixing tank 3. The solution 1 in the mixing tank 3 is fed to an electrodialysis device 4, and by electrodialysis, it is separated into demineralizecl liquid 5 from which univalent ions have been removed and univalent ion-concentrated liquid 6. When KCl 2 is added to increase the amount of K remaining in the demineralized liquid, the limiting concentration of univalent cations at which polyvalent ions starts to permeate can be lowered, compared with that before KCl addition. In this way, the remaining amount of Na after electrodialysis is reduced, and in order to satisfy electric neutral conditions in the solution, Cl ions are reduced.

摘要： PURPOSE:To sense defect of wafer in an early stage by judging the degree of cleanliness in the washing process for semiconductor wafer by means of in-line measurement. CONSTITUTION:A semiconductor wafer 1 is inserted between electrodes 2, 3 and placed on the former 2, and either the wafer is put in contact with the latter 3 or a space is provided. Externally, for example from a frequency response device 4, a high frequency voltage is impressed to the gap between these two electrodes 2, 3. Therein the wafer 1 and impurities have different electric resistances and capacitances, and therefore, their components are separately measured by varying the frequency of the impressed voltage. This electric resistance is proportioned to the thickness of impurities and is in inverted proportion to the area, while the capacitance is in inverted proportion to the length and is proportioned to the area. Accordingly changes in the thickness and area of the impurities become apparent as changes in the electric resistance and the capacitance, which are thus measured.

摘要： PURPOSE:To prevent the titled membrane filter from getting clogged by forming a precoat material layer, injected from outside into a liquid, on the surface of a hollow yarn membrane on the raw water side before or during the operation and removing solid matters and ions in the raw water. CONSTITUTION:Solid materials and ions in the raw water are removed by forming a precoat material layer, injected from the outside into the liquid, on the surface of a hollow yarn membrane on the raw water side before or during the operation at the time of removing impurities in the liquid by means of a hollow yarn membrane filter. The particle diameter of said precoat material should be larger than the bore of the membrane and preferably 1-10mu, and desirably of compressive resistance and crystallizing properties. For example, crystalline iron oxide Fe2O3 and Fe3O4 can be used. As a result, a hollow yarn membrane filter used for condensate purifying system in an atomic power station or the like can be prevented from increasing waste and clogged membrane as much as possible and the life of the membrane can be longer.

摘要： PURPOSE:To effectively dissolve and remove the clad deposited on the membrane surface in the separation of the clad in the cooling water of an atomic power plant by bubbling an acidic soln. contg. gaseous carbon dioxide on the hollow yarn membrane surface on which particles are deposited. CONSTITUTION:The raw water such as atomic power plant cooling water is introduced from an inlet hole 2 at the lower part and the filtered water is obtained from an outlet pipe 3. When the clad is deposited in the stationary operation of the hollow yarn membrane filter and the pressure drop in filtration is increased, backwash water is passed from the inside of a module, a 2-phase flow of water and gas into which gaseous carbon dioxide is forced and the metallic oxides deposited on the membrane surface are dissolved in the acidic medium. The gas after bubbling is discharged from a valve to the outside 15 of the system and the liq. is returned to a gaseous carbon dioxide pressure vessel 12 through a clad removing filter 16. Gaseous carbon dioxide 17 is formed into the gaseous carbon dioxide pressure vessel in accordance with the pH of the liq.

摘要： PURPOSE:To permit removal of BOD in waste water by pretreating the waste water in a catalytic oxidation tank and a pressure flotation separation tank prior to treating of the same in an active carbon packed electrolytic cell. CONSTITUTION:The waste water treatment device is constituted of a catalytic oxidation tank 1, a pressure flotation separation tank 2, and an active carbon packed electrolytic cell 3. The tank 1 is of a double cylindrical shape, into which the foam of air is introduced from the bottom part of a cylindrical part 4. Packings for the purpose of formation of biological membranes are loaded in an outside circumferential part 5. The liquid can be circulated by the ascending foam of the part 4. The tank 2 is of a cylindrical shape, and a flocculating agent 8 and the pressurized water from an air dissolving tank 9 can be injected through an inlet 10 into a central inside circumferential part 7. A scraper 11 for recovering of froth is provided in the upper part of the floating part. The tank 3 is constituted of a flotation part 12 with a flow regulating cylinder, a scraper 14 for recovering froth and an electrolytic part 13 packed with a granular active carbon between the cathode and the anode. When the waste water is pretreated with such tanks 1, 2, the waste water is made lower in molecules on account of the property changes of org. materials and the org. materials are effectively oxidized and decomposed in the tank 3.
