Title: Method for preventing deposition of scale
Inventor: SAWADA IWAO
IPC: C02F1/04
Filed: 1985-06-04
Abstract: PURPOSE:To eliminate the deposition of scales on a cooling pipe, etc., by introducing a high-temp. liq. to be treated contg. scale components into a multi-flash evaporator. CONSTITUTION:A liq. to be treated kept at high temp. is introduced from a geothermal water supply pipe 17 into the maximum-temp. stage 6a of a multi- flash evaporator 1, successively evaporated at each state and sent to the minimum-temp. stage 6n. Solid components formed by the evaporation, concentration and cooling are removed from the liq. in a setting vessel 11. Distilled water generated in the evaporator 1 is mixed from a pipe 13. The dilute water is recirculated to an evaporator 7, which is incorporated into the evaporator 1 or provided in its vicinity, from a pipe 24, heated therein by using steam generated in the evaporator 1 to increase the solubility and returned to a reducing well from a pipe 25. Consequently, the deposition of scales on a cooling pipe is eliminated and the scales can be efficiently separated.

Title: Vortex flow prevention device for water tank of pump suction
Inventor: SUDOU SUMIO
IPC: F04D29/66
Filed: 1979-09-25
Abstract: PURPOSE: To prevent generation of vortex flow for certain with a small amount of sprayed water, by providing a water stream jetting device which jets a water stream above the water level of a water tank.  
     CONSTITUTION: A water flow jetting device 11 which jets out a water flow on to the water level of a water tank is installed, and it jetts out a suitable amount of water flow to a place on the water level where a vortex flow develops. By this arrangement the water flow jets fly through the air and strikes directly the water level in the vicinity of which a vortex flow develops. Because the momentum of the jet effectively changes the surface flow of the water at the vortex flow, a small amount of water spray makes sure that development of vortex flow is suppressed.

Filed: 1979-09-26
Abstract: PURPOSE: To realize not only a simple structure but high reliability for a quake sensor, by providing several quake detection parts which detect the external vibration by the fall of a weight supported in the quasisteady state, deciding the operation of only one, a prescribed number of units or the most of these detectors, and then giving the alarm or the control output in accordance with the result of the above decision.  
     CONSTITUTION: The weight 10 is supported on the cup-shaped cradle 2, and the mobile contact 3 is away from the fixed contact 4 against the spring 5. Thus the terminals (a) and (b) are opened. The weight 10 falls by the external vibration to be held on the circular cradle 6. In this instant, the contacts 3 and 4 are closed by the spring 5. The voltage is applied to the terminals (c) and (d), and the cradle 6 is raised up via the coil 9 plus the sucking force of the plunger 8 to reset the weight 10 to the original place. The detection part 1 is provided in several (3) units, and thus just one unit of the weight fallen is reset to the original position via the majority circuit consisting of the relays C 1 WC 3  plus the contacts X 1 , X 2 , (a), (b), (c) and (d) each. While an alarm is produced in case most of the weights fall. As a result, both a simplified structure and high reliability are obtained for a quake sensor.

CONSTITUTION:The compsn. of the steel is formed of by weight, 0.08 to 0.16% C, 0.8 to 1.2% Si, 0.1 to 0.6% Mn, 7 to 9% Cr, 0.5 to l.5% Mo, 0.5 to 1.5% W, 0.1 to 0.6% V, 0.03 to 0.1% N and 0.0005 to O.O7% rare earth metals and furthermore contg. 0.01 to 0.1% of one or two kinds selected from Nb and Ti, and the balance substantial Fe. Since its high temp. strength and toughness deteriorate in the case the amt. of delta-ferrite reaches >=10%, the Cr equivalent is regulated to <=15% to prevent the appearance of 6 delta-ferrite. Thus, a part of Mo is substituted by W, and N is incorporated therein. By the conversion into low C-high Cr and the incorporation of Nb and Ti, its transformation point is raised.

Also, the registers R1 and R2 used only in the multiplier MUL in the plural registers R1-R4 are arranged on the side closer to the multiplier MUL further and the registers R3 and R4 used only in the accmulator ACC are arranged on the side closer to the accumulator ACC. Thus, the need of providing an area for unrelated wiring is eliminated. Further, since wires SL1 and SL2 for connecting the registers R1 and R2 used only in the multiplier MUL and the multiplier MUL are not wired to the accumulator ACC, the size of the entire module is reduced.

Abstract: PURPOSE:To stably execute high denitrification and dephosphorization by opening and closing a valve of an air feed port to attain anaeration and aeration states and executing only the stirring by lowering the rotating speed of an aeration machine in an anaeration time zone. CONSTITUTION:A negative pressure is generated in the front end part of a screw 5 and the air is sucked from an air intake port 10 at the front end of an air suction pipe 8 and is released from the front end of the screw 5 into water when a motor 2 is operated to rotate the screw 5 by opening the valve 9 of the aeration device to be used for a biological treatment of org. waste water. The slow stirring to the extent of preventing the sludge in the treatment tank from setting is executed by lowering the rotating speed by an inverter 11 connected to the motor 2 and a control panel 12 and further by closing the valve 9 at the time of only the stirring. The respective states of anaeration and aeration are thus created and the high denitrification and dephosphorization are executed stably without overloading of the motor.
