摘要： PURPOSE:To intermittently exhaust the air oozing out into a reduced-pressure vessel with a small-sized and inexpensive vacuum pump having low output by providing a highly airtight two-position and three-port solenoid valve in a pipeline between the reducedpressure vessel and vacuum pump of a deaerator. CONSTITUTION:The change in the vacuum in the reduced-pressure vessel 1 is detected by a pressure sensor 7. The vacuum pump 5 and solenoid valve 11 are operated so that the vacuum is controlled within the upper-limit and lower-limit values set by a pressure control circuit 8, and repeatedly and intermittently operated. In this case, the pipelines of the always closed port 13 and always opened port 14 are switched by the time-lag operation of the vacuum two-position and three-port solenoid 11 to allow the always closed port 13 to communicate with a selector port 15, hence the exhaust port 16 of the reduced- pressure vessel 1 communicates with the suction port 17 of the vacuum pump 6, and the air oozing out into the vessel 1 is discharged to the outside. As a result, the exhaustion by the intermittent operation can be performed even with an inexpensive commercially available pump.

摘要： PURPOSE: To generate high added value data by giving data integration functions in state input units, transmitting integration data in accordance with a data request from a data integration unit and zero-resetting integration data and integrating data again after transmission terminates. CONSTITUTION: The data integration unit 1 transmits reset signals to all the state input units 2 when a working rate summing-up device rises. The state input units 2 receiving the reset signals once zero-reset integration data of the data integration parts 2b and time-integrate data from state input parts 2a in the data integration parts 2b. Thereafter, the data integration unit 1 executes polling P1 which is to sequentially request integration data to the respective state input units 2 at every prescribed period, and data is transmitted S1 to the data integration unit 1. Then, integration data is zero-reset and time integration is started again. It is repeated for the number of the state input units 2.

摘要： PURPOSE:To improve degasification efficiency and to reduce the amt. of a reagent retained by making a thin tube porous to pass a liq. to be degasified, coating the inner surface of the thin tube with a gas-transmissible membrane and using the plural thin tubes in parallel. CONSTITUTION:The degasifier is formed by the thin tube 16, a vacuum vessel 4 for keeping the outside of the tube 16 vacuum and a device 12 for evacuating the vessel 4. The tube 16 is made porous, the inner surface of the tube 16 is coated with a gas-transmissible membrane, and the plural tubes 16 are used in parallel. Namely, since the diameter of the flow passage can be reduced and the membrane thinned, degasification efficiency is improved, and the amt. of a reagent retained is reduced.

摘要： PROBLEM TO BE SOLVED: To provide an organic waste treatment apparatus capable of being miniaturized and enhanced in efficiency. SOLUTION: First and second treatment tanks 1, 2 packed with microorganisms are arranged up and down in a vertical direction and first stirring blades 10 stirring microorganisms and org. waste are arranged in the first treatment tank while second stirring blades 20 stirring microorganisms and org. waste are arranged in the second treatment tank and the first and second stirring blades 21, 20 are driven by the same stirring blade rotating shaft 3. By this constitution, microorganisms different in optimum environment can be utilized and the enhancement of efficiency can be achieved and, by using the rotary shaft of the stirring blades in common, the miniaturization of the apparatus can be realized.
