摘要： PROBLEM TO BE SOLVED: To treat garbage surely to have a desired water content finally. SOLUTION: A controller 15 monitors the temperature of garbage 3 and the temperature of a treatment tank 1 by the first and second detectors 81, 82. When the temperatures reach respectively pre-determined values, since treatment is made to be finished, the temperature of the treatment tank 1 and the water content of the garbage 3 can be made to correspond to each other. Therefore, when the temperature of outside air changes, or even when the volume of the garbage 3 changes, the water content of the garbage 3 in the treatment tank 1 at the point of time of the end of treatment can be made to be a nearly desired value. Accordingly, irrespective of the variation of the temperature of outside air and the quantity of he garbage 3, the end of drying can be judged surely so that stable garbage treatment can be implemented.

摘要： PURPOSE:To prevent the destruction of a migration sample by constituting the device of electrodes of a superconductor ceramic material which has the superconducting transition temp. of ordinary temp. or above and below the destruction temp. of a migration sample and turns to an insulator at the temp. above the destruction temp. of the migration sample. CONSTITUTION:Both of the positive electrode 7 and the negative electrode 8 are constituted of the material of the superconductor ceramics. The superconducting transition temp. is the temp. exceeding ordinary temp. in order to maintain nearly 0 electric resistance at ordinary temp. These electrodes are the insulators so as not to be energized when the migration sample attains about the temp. at which the sample is destroyed. Then, the positive electrode 7 and the negative electrode 8 are the good conductors at the temp. above ordinary temp. and are the insulators and are not energized upon attainment of the destruction temp. of the migration sample and, therefore, the migration sepn. is not adversely affected in the event of an abnormal rise of the temp. of a migration chamber 1 by a cause, such as cooling water 22.

摘要： PURPOSE:To enhance the sepn. performance of a migration sample and t automate the sepn. and refining of the migration sample by providing a bubble removing means which removes the bubbles existing in the buffer soln. in a migration chamber. CONSTITUTION:A buffer soln. is previously injected from an introducing hole 3 into the migration chamber 1 to form parallel flow. The migration sample is cracked to each of the respective components when the migration sample is injected from an injection pipe 4 into the chamber. These components are fraction collected from a fraction collection port via a fraction collection pipe 7. The bubbles float on the buffer soln. surface if the bubbles exist in the buffer soln. at this time. The bubbles are sucked through a pass filter 19 for gas, a filter retainer 21 and a suction pipe 23 into a vacuum pump 22 and are dis charged to the outside. Namely, the bubbles can be surely discharged even if the bubbles exist in the buffer soln. and, therefore, the sepn. performance of the migration sample is enhanced. In addition, the efficiency of the sepn. operation is enhanced as well as the bubbles can be removed even if a power source is not interrupted.

摘要： PROBLEM TO BE SOLVED: To check the generation of hydrogen gas and to enable the stable generation of strongly acidic water. SOLUTION: Since the cross sections of cathode chambers D-F are made greater than those of anode chambers A-C, and the volumes of the cathode chambers D-F are made greater than those of the anode chambers A-C, the amounts of raw water which passed through the cathode chambers D-F are made greater than those of the raw water which passed through the anode chambers A-C. Accordingly, in the cathode chambers D-F, since the amounts of passage of raw water are made greater as compared with the anode chambers A-C, and the activation of raw water to be electrolyzed can be attempted, the generation of hydrogen gas can be minimized so that the effect for the generation of strongly acidic water can be stabilized.

摘要： PURPOSE:To miniaturize the circuit constitution by using a voltage comparator to compare an output of a frequency-voltage conversion circuit with an output of a reference setting circuit and outputting the result to improve the communication efficiency when FSK communication is applied, where a data transmission rate and a FSK carrier frequency are adjacent comparatively. CONSTITUTION:The FSK wave inputted from an input terminal 1 is bisected at a signal branch point 2. The signal fed to the frequency-voltage conversion circuit is received by a buffer amplifier 3, inputted to an active low-pass filter 5, subjected to amplitude limit at each frequency and becomes a signal corresponding to digital data by a detection circuit 6. On the other hand, the signal is received by a buffer amplifier 4 in a reference voltage generating circuit, the result is detected by a detection circuit 7, attenuated by an attenuator 8 comprising resistors and a reference voltage proportional to the input signal level is obtained. The bisected voltage is inputted and compared by a voltage comparator 9 to recover accurate data. Thus, the circuit is miniaturized to improve the demodulation efficiency and the circuit constitution is miniaturized.

摘要： PROBLEM TO BE SOLVED: To easily deal with a change in a treated water volume by enhancing the treatment effect of water with extremely simple constitution and easily assembling magnets, to prevent the circulation of crushed 'BAKUHANSEKI' (siliceous stone produced in Japan) and to prevent the clogging of the granite porphyry between ceramic balls. SOLUTION: When a filter 16 is arranged on the upstream side of a magnet body 13 and if the 'BAKUHASEKI' 15 is bombarded and crushed by the flow of the water, the 'BAKUHANSEKI' pieces enter the inside of a water storage tank 11. Since the 'BAKUHANSEKI' pieces are captured by the filter 16 through a pump 12 by the suction of the pump 12, the clogging of the 'BAKUHANSEKI' pieces between the ceramic balls 14 is surely prevented and the good state of the circulating flow of the water is maintained. When the crushed 'BAKUHANSEKI' pieces are captured by the filter 16, minerals are eluted from the 'BAKUHANSEKI' pieces as well by the circulation of the water and, therefore, the water treatment effect is additionally enhanced.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive drier capable of drying garbage rapidly and preventing the leakage of malodorous air. SOLUTION: A downward air current shown by arrows is generated by a fan 25 fixed to the upper tip of an agitating shaft 21 in correspondence to the size of the fan 25, the air current efficiently hits a material 10 to be treated while agitating almost the whole air in a treating tank 2, and the material 10 is rapidly dried. Since the fan and agitating shaft 21 are driven by the same drive source, the production cost and running cost are reduced. Since the air is not sent into the treating tank 2 under pressure, the air never leaks out from an inlet door 2a or a front door 1a, the environment is not polluted, and the device need not be made precisely airtight.
