摘要： PURPOSE:To perform condensation of water vapor contained in discharged gas and concurrently eliminate noise of a vacuum pump as well as extend the life of a deodoring device. CONSTITUTION:A condensor 2 into which discharged gas containing water vapor caused to flow from a vacuum pump 1 is provided with a plurality of expansion and shrinking chambers through which discharged gas passes while repeating expansion and shrinking by a condensing wall (a partition wall) 21. The condensor 2 is also operated as a muffler. In addition, water condensed at the condensor is dripped into a condensed water tank 3, discharged gas caused to flow from the condensor is always passed through the dripped water, thereby water-soluble odor component contained in water solution in the discharged gas is resolved and removed. In addition, a deodoring device 4 is connected to an air outlet extending from the condensed water tank and the discharged gas washed with water is further deodored.

摘要： PURPOSE:To efficiently perform heating and drying by preventing condensation of vapor at a location distant from an exhaust port, counterflow of water after condensation and closing of the exhaust port, and effecting vacuum exhaust without lowering an efficiency of exhaust. CONSTITUTION:An inner bag 8 containing an object to be processed is attached to an exhaust port 2 having substantially the same size as that of an opening of the bag and connected to a vacuum pump 7 through a microwave-permeable hose 4. An exhaust system piping except for the vacuum pump 7 is provided within a microwave shielding vessel 10. Vapor as generated is heated during vacuum exhaust and efficiently transferred, so that the object being processed is efficiently heated and dried at low temperatures. Thus vapor separated from the object being processed is heated in a vapor transfer path leading from the large exhaust port, which is effective in enhancing an efficiency of vapor transfer.

摘要： PURPOSE:To permit vacuum heating treatment without introducing substance to be treated into a pipeline for evacuation and without applying any unnecessary load on an evacuating means by a method wherein the present device is provided with a supporting means, supporting the receiving body of the substance to be treated, which is installed in a high-frequency shielding vessel, the evacuating means in the receiving body and a hydrophobic body, arranged between the receiving body and the evacuating means. CONSTITUTION:When a vacuum pump 4 is operated to evacuate the inside of a receiving body 10, air in the receiving body 10 is discharged from an evacuating port 7 through an evacuating pipe 6. The flexible receiving body 10 is contracted by an external pressure to the same degree as the volume of a substance to be treated 20 while the substance to be treated 20 is pulled up to the vicinity of the evacuating port 7. When microwave generating device 2 is operated under this condition and microwave is projected from a wave guide 3 against the substance to be treated 20, moisture, contained in the substance to be treated 20, starts evaporation at a low temperature since the pressure of the atmosphere is reduced and a boiling point is lowered. On the other hand, the vacuum evacuating port 7 is provided with a hydrophobic body 8b whereby liquid drops (sprach or the like), dispersed while being mixed with water vapor, can be arrested.

摘要： PURPOSE:To prevent the decrease of a sample concn. and the increase of a sample bore and to improve migration sepn. performance by adopting multiple pipes to the sample injecting pipe of the electrophorectic device consisting of a migration cell, buffer soln. system, sample injecting pipe, electrolyte system, electrode, and DC power source and passing the sample to the inner pipe and the buffer soln. to the outer pipe. CONSTITUTION:The buffer soln. is drawn out of a buffer soln. tank 16 and is admitted from a buffer soln. inflow port 6 into the migration cell 1, from which the buffer soln. is made to flow downward as parallel flow. The sample injecting pipe is made of, for example, double pipes 11. The sample is passed through the inside pipe 14 and the buffer soln. is passed through the outside pipe 15 by driving a sample pump 12 and is injected through the sample injecting part 5 into the buffer soln. in the migration cell 1. The spread of the sample near the injecting part 5 is prevented by using the double pipes 11 in this way, by which the degradation of the migration performance is averted. The buffer soln. carrying the sample is thereafter passed through the inside of the electric field formed of electrodes 3a, 3b and is subjected to migration and sepn. The sample is moved toward the electrodes by the respective charges and is fraction-collected in a fraction collection port 7. The remaining buffer soln. is discharged from an outflow port 8 by using the pump 9.

摘要： PURPOSE:To provide the recycled water treating equipment capable of completely separating the impurities from the concd. water generated from a water treating device and capable of being operated even in an agravity state. CONSTITUTION:The concd. water 106 from a water treating device 101 (mainly for membrane distillation) is atomized by a nozzle 108 in a crystallization part 117, brought into contact with the gas 107 heated by a heater 104 and vaporized, hence the impurities in concd. water are suspended in the gas as solid particles, and the particles are removed by a filter 111. The high-humidity gas 112 freed of the particles is separated by a dehumidifier 103 into water 114 and a gas 113, and the water 114 is returned to the water treating device 101 and the gas 113 to the heater 104. The moisture in the high-humidity gas 112 is absorbed in a liq. absorbent through a hydrophobic porous membrane in the dehumidifier 103, the moisture in the absorbent is recovered as water through another hydrophobic porous membrane, or the moisture in the gas 112 is cooled and condensed and then the water droplets and the gas are separated by the hydrophobic porous membrane.

摘要： PURPOSE:To improve cooling characteristics by a method wherein a fixing means, fixing a body to be cooled to a heat exchanging means, is provided while the variability in the shape of a plurality of cooling elements and the amount of contraction of the cooling elements upon cooling are compensated by the deformation of an elastic body having a good heat conductive property. CONSTITUTION:A cooling device 20 is constituted of a plurality of thermo-electric elements 1, an elastic body having good heat conductive property such as the sheet 7 of silicone rubber, which is arranged at the heat absorbing side of the thermoelectric elements 1 and added with boron nitride, a body 2 to be cooled, which is arranged on the sheet 7, and a heat exchanging means such as a heat exchanging member 4 arranged at the heat dissipating side of the thermoelectric element 1 while the flow passage 3 of cooling water is provided in the heat exchanging member 4. The body 2 to be cooled and the heat exchanging member 4 are fixed rigidly by a fixing member 5. The body to be cooled 2 and a heat exchanging member 4 are fixed rigidly by a fixing member 5. When the height of the thermoelectric elements 1 is contracted relatively due to the difference of linear expansion coefficients between the thermoelectric element 1 and the fixed member 5, the amount of contraction is compensated by the expansion (or restoring) of the sheet 7.

摘要： PURPOSE:To reduce the power consumption when a closure state is maintained and to improve the resposiveness in thawing by cooling the fluid below its freezing tempera ture and closing the fluid passage when the fluid passage is closed, and rising the fluid temperature almost to the freezing temperature after the freezing. CONSTITUTION:A valve 1 which opens and closes the fluid passage 3 is arranged around the fluid passage. The temperature at which the closing function of the fluid passage can be maintained is much closer to the freezing temperature of the solution in the valve than the temperature of the solution at which the solution is frozen to close the fluid passage. Namely, the fluid passage can be held closed even when the temperature of the solution is put back almost to the freezing temperature after the solution in the valve is frozen temporarily to displays the fluid passage closing function, and electric power supplied to a cooling and heating means 2 may be small. Further, when the valve is opened, namely, when the solution is put back into liquid by heating the fluid passage opening/closing valve by the cooling and heating means 2 in the fluid frozen state, the solution is only heated from temperature extremely close to the freezing temperature to the freezing temperature.

摘要： PURPOSE:To prevent internal attachment of a living body specimen and preclude it from damage, vibration, and noise generation by utilizing freezing of fluid such as a solution in a flow path and phase change in fusion, and obtaining automatic blocking and opening of the flow path. CONSTITUTION:A cooling/heating means 1 using a thermoelectrical element is arranged as surrounding a heating flow path 4 to be cooled, and its heat absorption and heating are conducted to this heating flow path 4 formed from a flow path forming material 3 through a heat transmitting means 2, and thereby fluid such as the solution situated internally is frozen or melted. Thus blocking and opening of the flow path 4 are performed. Therein the cooling/heating means 1 is controlled electrically by a control means 6 on the basis of the fluid temp. sensed by a temp. sensor 7. The heating flow path 4 to be cooled is furnished on each of the flow paths, which enables selective opening/closing of the flow paths in case cooling and heating are made by a heat exchange means 5 through the heat transmitting means 1. The configuration is free from mechanical moving parts, so that internal attachment of the living body specimen and its damage, vibration, and noise generation are prevented.

摘要： PURPOSE:To perform the opening and closing control of the flow of a fluid, by freezing/thawing either one of a fluid container and a part of the flow passage connecting the container to a fluid injection/ejection port by a freezing means. CONSTITUTION:The fluid container 6a ready to eject a fluid is thermally insulated in a non-frozen state by a freezing means 9a while the other containers 6b, 6c are thermally insulated in a frozen state by freezing means 9b, 9c. The heat insulating temp. at this time is set to one optimum to the long-term preservation of a liquid. Therefore, the fluids in the fluid containers 9b, 9c are frozen to become impossible to flow to a flow passage 4a and the containers 9b, 9c become such a state that the end parts therein are closed by valves. Further, by bringing adiabatic flow passages 10a-10f to a frozen state by freezing means 9d-9i, a secondary fluid supply part 7, a secondary fluid discharge part 8 and flow passages 4a-4c become the same state as if they are closed by valves. When a pump 5a is driven in this state, the fluid is injected in an objective apparatus from a fluid injection/ejection port 1.

摘要： PURPOSE:To parcel samples of equal charge at a high accuracy, by arranging a parcelling hole and a tank liquid drain hole separately. CONSTITUTION:A buffer introducing tube 4 and a sample injection tube 2 are provided at the top of a migration tank 1, electrodes 6 and 7 and an electrolytic liquid tank 20 at both ends thereof in contact with the migration tank 1 through membranes 8 and 9, a parcelling section 3 at the thickness-wise center of the lower part thereof and a tank draining tube 5 on the bottom thereof. A buffer 102 is introduced from a buffer introduction tube 4 while a sample 101 from a sample injection tube 2 and when an electric field is applied to the electrodes 6 and 7. The sample 101 is separated into components. The parcelling sample 104 thus separated is introduced into a parcelling container 14 from a parcelling hole 21 and a tank liquid 103 not parcelled is introduced into a tank liquid drain container 19 from a tank liquid drain tube 5. This enables the parcelling of the sample only from the tank thickness-wise center with a smaller speed difference in the tank liquid within the migration tank thereby allowing highly accurate parcelling of samples of equal charge.
