When a current ic is supplied to a coil 102 of the inductor 1, a magnetic core 101 moves into a mixture area from a Meissner area and has a certain finite permeability. As a result, the coils 103 and 104 have the magnetic flux changes and the function of a transformer is produced between both coils. Then both transistors TR1 and TR2 perform the switching actions alternately owing to the forward feedback attained by the transformer function. Thus a multivibrator is started. Then the currents i1 and i2 flow to both coils 103 and 104 respectively. As a result, a mixture state is kept and an oscillating action is carried on.

Abstract: PURPOSE: To measure the moisture content of the material before weighing and obtain an accurate mixing ratio, by pressing the measuring electrode to the material supplied into a weighing hopper and measuring the electrostatic capacity of the material between needle electrodes.  
     CONSTITUTION: The material, such as sand, stored in a silo 1 through a conveyor 3 is fed into a weighing hopper 4 by opening a gate 2, and this gate 2 is closed when reaching the set weighing value as being detected by a weighing means. When the material 9 is supplied into the weighing hopper 4 in this way, an air cylinder 8 is operated to press a measuring electrode 7 to the material 9. The central needle electrode 11 of the measuring electrode 7 is connected to the conductor of a coaxial cable 14, while the both side needle electrodes 12 are connected to the external conductors of the cable. When the needle electrodes 11, 12 are pushed into the material 9, since they are connected to a resonance circuit through the cable 14, the resonance will be deviated due to the electrostatic capacity of the material 9. The moisture content is determined by measuring the electrostatic capacity. Thus, the moisture content at the time of weighing may be measured, so that an accurate mixing ratio may be obtained.

Abstract: PROBLEM TO BE SOLVED: To facilitate the maintenance by supplying gas from one end of a reaction tube to treat a wafer, turning the gas at the other end of the tube, feeding it to the one end side of the tube, and exhausting the gas out of the tube. SOLUTION: The exhaust gas in a treating space 3 is fed to the exhaust space 4 between an inner tube 2a and an outer tube 2b to make it possible to exhaust the treating fluid 11 supplied from the lower end of a reaction tube 2 again from the lower end of the tube 2. Thus, the upper end of the tube 2 can be formed in a closed structure, the tube 2 can easily be removed merely by removing the coupling part of the lower end side of the tube 2, an in the case of the maintenance of the apparatus, the operating efficiency can be raised. The gas supplied from the one end of the tube treats a wafer 5, is turned to the other end side of the tube 2 and exhausted out of the tube. Accordingly, a foreign matter is scarcely deposited on the inner wall surface of the tube 2, thereby making it possible to suppress the contamination of the wafer 5 due to the drop of the foreign matter.

Abstract: PURPOSE:To reduce impact at the end of a magnetic tape to make possible accurate intermusic detection by controlling the rotational speed of a reel drive motor on the basis of on/off signals of switch means turned on and off by the centrifugal force accompanying rotation of each reel block. CONSTITUTION:When the number of revolutions of a take-up reel base 2 or a supply reel block 3 are higher than a fixed value, switch means 4 or 5 is turned off by the centrifugal force and an off signal is outputted to a drive motor 49 from an on/off detector 6 to turn off the electrical source of the motor 49 to lower the number of revolutions of the reel base. As the number of revolutions of the reel base is lowered, means 4 or 5 are again turned on to turn on the power source of the motor 49 to increase the number of revolutions. In this manner, the number of revolutions of the reel base never exceed a fixed value so as to inhibit application of large shock to deteriorate the magnetic tape while allowing to accurately execute intermusic detection.
