Inventor: NAKADA MAKOTO
IPC: C02F3/00
Filed: 1994-03-03
Abstract: PURPOSE:To perform highly efficient purifying treatment by reducing the change of a water sending amt. caused by the fluctuations of the water level in an underwater pump arranged tank by reducing the number of rotations of a pump motor when the water level in the underwater pump arranged tank is high and increasing the same when the water level in low. CONSTITUTION:An underwater pump arranged tank 2 is installed to the front stage of a treatment tank 1 once storing living waste water while a pump motor receiving an electric signal from a control circuit to be driven in the number of rotations corresponding to the fluctuations of the water level in the underwater pump arranged tank 2 and an underwater pump 5 driven by the pump motor and placed underwater in the underwater pump arranged tank 2 are installed. A water level detection means 6 attached in close vicinity to the underwater pump 5 takes out a detected water level as an electric signal to send the same to the control circuit. The control circuit receives the electric signal from the detection means 6 to send an electric signal, which decreases the number of rotations of the pump motor when the water level in the underwater pump arranged tank 2 is high a increases the same when low, to a pump driving device part.

Abstract: PURPOSE:To move a switching valve piece upon the initial stage of operation thereof so that is enters into a downward stroke even if it is located at any position and smooth the operation thereof by a method wherein the switching valve piece is made so as to have a configuration having an area difference between the upper and lower surfaces thereof. CONSTITUTION:Primary fluid, entered from a primary fluid supplying port 2, passes through a path 15 and arrives at the path 16 when the valve piece is located at the initial position thereof which is shown in the diagram. Then the switching valve piece 8 obtains a downward force by the pressure of the primary fluid communicating with a stepped part 8' formed by the phiC and phiB parts of the valve piece 8 and begins to move downwardly. In another diagram showing the intermediate position of the valve piece, the pressure of the primary fluid is acting on the (phiC-phiA) part and the (phiC-phiD) part of the switching valve piece 8 which began to move, however, the upper surface or the (phiC-phiA) part 81 has the area larger than the same of the lower surface or the (phiC-phiD) part 82, therefore, the switching valve piece 8 moves downward further. Thus, the operation of the valve piece may be made smooth by a method wherein the switching valve piece 8 is moved downwardly at the beginning of the operation thereof.

Title: Multivibrator circuit
Inventor: KONNO AKIRA
IPC: H01H47/02
Filed: 1981-04-22
Abstract: PURPOSE:To constitute the circuit using one relay in a multivibrator circuit made up of a relay by driving the relay using a condenser which is charged and discharged by operation of a switch. CONSTITUTION:A power source E generates voltage V which is sufficient to drive a relay RL. At ordinary times, contact terminals C and NC of a momentary transfer switch SW are connected by own pressure B. Only when input or mechanical pressure A is applied, the contact terminals C and NO are connected, and when external pressure A is released, connection by pressure B is restored. When voltage is applied to the coil of the relay RL through a signal line l, a switch circuit S1-n operates and connection of contact teminals C-NC is changed to connection of contact terminals C-NO. Connection is restored by release of voltage. A condenser C is charged and discharged according to the switch SW and th relay RL. By this way, a bistable multivibrator circuit can be constituted using one relay RL.

Title: Method and device for detecting creeping discharge on porcelain insulator, tube or the like
Inventor: MATSUDA SADAMU
IPC: G01R31/12
Filed: 1979-05-16
Abstract: PURPOSE: To quantitatively detect a discharge current, by separately measuring a discharge current component and a leakage current component flowing through a wet surface layer, in each cycle of power voltage.  
     CONSTITUTION: When creeping discharge occurs on a sample 18, a total current flows through a detection resistor 19 and a voltage appears across it. The voltage is applied to a sample/hold circuit 21 through an amplifier 20 and held. A dropped sinusoidal AC voltage is applied from an insulating transformer 16 to a control signal generator 23 and a multiplier 24 through another amplifier 22. A differential amplifier 25 takes the difference between the output voltage of the multiplier 24 and the voltage held by the sample/hold circuit 21 and applies the difference to an analogue switch 26. This switch is opened for a time from t 0 Wt 1  to pick out a discharge current component from an output terminal 27. The discharge current can thus be quantitatively detected.

Of the two regions 1a and 1b equipped with the same profile in a semiconductor substrate 1, ions are driven only into the region 1a. The region 1a is exposed to etching while the quantity of ions or a current (y2) is determined as indicated in a mass spectrometer. The absolute value of an ion injection peak value 1c is determined in view of the depth (y1) and the concentration (x1). The absolute value of 1d is determined by relative comparison with the ion injection peak value 1c. A current 1e is obtained by changing the specimen setting. The absolute value of the current 1e is equal to the absolute value 1d. The concentration 1f that is the wanted quantity is determined by relative comparison with the current 1e.

Title: Production of functional glass with high abrasion resistance
Inventor: NAKANO KENJI
IPC: C03B27/00
Filed: 1983-04-07
Abstract: PURPOSE:Optical thin films of specified composition are formed on the glass surfaces and the product is heated and rapidly cooled to form functional glass of high abrasion resistance. CONSTITUTION:The glass plate base 1 is coated with thin films of CeO2 21 and thin films of SiO2 22 alternately into multilayers by vacuum deposition. At this time, thin films of Al2O3 or ZrO2 23 are formed between both thin films 21, 22. The resultant glass plate is heated at 650-700 deg.C for about 15min, then rapidly cooled at a cooling rate over 100 deg.C/min by blowing cold air onto both surfaces. The above heat treatment diffuses the Al2O3 or ZrO2 between both layers into the CeO2 film and the SiO2 to form the diffusion layer 23. Further, the rapid cooling develops compression stress on the glass surfaces to increase the thermal and mechanical impact strength and abrasion strength of the glass surface by 3-5 times.

Abstract: PURPOSE:To control the temperature in a furnace body in safety through a small-capacity SCR by correcting the difference between the temperature in the furnace body and temperature set by a temperature program, determining the ignition angle of the SCR and driving the SCR, and preventing a large current from flowing at a time. CONSTITUTION:The difference between the detected temperature Ta in the furnace body 16 and the temperature Tp set by the temperature programmer 11 is found by a temperature difference detector 12 supplied as a signal (d) to a PID circuit 13 for PID arithmetic, thereby outputting a signal P to a correcting arithmetic circuit. The correcting arithmetic circuit 9 uses the furnace temperature Ta to correct a signal (h) into Pcorr, which drives an ignition angle converting circuit 14 to output an ignition angle thetacorr for control over an SCR driver 15, supplying a heater 17 with electric power corresponding to the ignition angle. Consequently, when the temperature in the furnace is raised from the room temperature to 1,500 degrees by a program, a large current is prevented from flowing at a time and the temperature programmer 11 is put in safe operation by the small-capacity SCR.
