Title: Drain pit
Inventor: TOKORO SHIRO
IPC: E03F5/10
Filed: 1994-11-15
Abstract: PURPOSE: To prevent a pump from sand caught thereby and sludge sticking thereto, by inserting the suction inlet of a submerged pump in a drain pit made of a wall with holes, which is detachable from the bottom and double-structural, to serve as a filter. CONSTITUTION: Wall panels 2a, 2b provided with a number of holes on the the wall face and made of FRP (glass fiber-reinforced plastics) or vinyl chloride are detachably erected on the bottom 1 so as to have a double-structure and a filter material 7 like sand and gravel is charged therein to form a drain pit A opened at the top. The wall face 2 may be woven. This drain pit A is submerged in sewage F and the suction inlet of a submerged pump 6 is inserted in the drain pit A for pumping up to prevent sand and sludge in sewage from entering in the pit A. The drain pit is made so as to be easily transported, assembled, and disassembled at site. In this way, the working efficiency of the pump can be increased.

Title: Controller for reversible pump-turbine
Inventor: SAKAMOTO SHIGERU
IPC: F03B15/14
Filed: 1987-12-04
Abstract: PURPOSE:To perform pumping operation so efficiently by controlling a reversible pump-turbine with a lever-difference responding control means when a water- level difference between a lower dam and an upper dam exceeds a fixed value and with a load limiting means when it is less than the fixed value, respectively. CONSTITUTION:When a water-level difference between an upper dam 1 and a lower dam 3 exceeds a fixed value, such as level-difference responding control that controls a guide vane 6a into opening where supply capacity for a generator motor 7 is constant and max. discharge quantity is secured, is carried out by a guide vane opening characteristic circuit 5b. On the other hand, when the water-level difference is less than the fixed value, the guide vane 6a is controlled so as to close its opening slightly by a guide vane opening limiting characteristic circuit 5c, and discharge quantity of a reversible pump-turbine 6 is limited to less than the max. discharge quantity, whereby overload in the generator motor 7 is prevented from occurring. With this constitution, stable operation can be done.

Title: Method for evaluating optical distortion
Inventor: SONDA YOSHIYUKI
IPC: G01N21/958
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To evaluate distortion, that a person feels, more precisely than two-dimensional evaluation by evaluating fluoroscopy distortion of a transparent plate-like body with the use of a three-dimensional form of a virtual image, after the three-dimensional form of fluoroscopy virtual image of a to-be-observed material formed with the transparent plate-like material in between is obtained. SOLUTION: Multiple real points 21 are formed on a to-be-observed material. The real point 21 looks as if it is at the point of a virtual image point 23 when the to-be-observed material is observed from the direction that the light beam group emitted from the real point is made incident to a pupil 22, through a transparent plate-like material. At this time, the point where the sum of the squares of the distances from the light rays is minimum is found to determine the point as the virtual image point. The group of obtained points is aligned three-dimensionally, and the three-dimensional form of the virtual image of the to-be-observed material is obtained. From the maximum and minimum values in the X axis direction of the three-dimensional form of the obtained virtual image, three-dimensional extent of the virtual image of the to-be-observed material is decided.  By this, fluoroscopy distortion of the transparent plate-like material is evaluated.

Title: Treatment of exhaust gas containing organic vapor
Inventor: ISHII KATSUMI
IPC: B01D53/22
Filed: 1990-11-13
Abstract: PURPOSE:To accelerate the transmission speed of organic vapor to recover the organic vapor efficiently and exhaust the organic vapor in gas at low concentration by condensing a transmission gas obtained by concentrating the organic vapor a gas separation film module by compression/cooling technique, and thereby recovering the organic vapor. CONSTITUTION:Transmisson gas in a gas separation film module which is returned from a return pipe 6 is allowed to join an exhaust gas from an exhaust gas source 1, then the confluent gas is pressurized by a compressor 4 and the compressed gas is conducted to a cooler 5. Then, an organic vapor which exceeds the saturated vapor pressure of the organic vapor at a cooler temperature is condensed and the condensed vapor is recovered. At the outlet of the cooler 5, an organic vapor equal to a saturated vapor pressure at the cooler temperature is present. This gas is conducted to the gas separation film module 2 by the fluid energy of the gas, and the organic vapor in a feed gas transmits through the film at a faster transmission speed than air under a specific differential pressure between films obtained by the control of a pressure adjustment valve 32. The faster transmission speed is caused by the selective transmissibility of the film. Thus, the organic vapor concentration of the transmission gas is thicker than the organic vapor at the outlet of the cooler 5.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject preliminary foamed particles not causing aggregation and blocking and enabling shortening of molding and cooling time, etc., in an internal die molding by decreasing an inorganic dispersing agent attached to polyolefin-based preliminary foamed particles to a specific amount or below. SOLUTION: The amount of an inorganic dispersing agent attached to the surface of polyolefin-based preliminary foamed particles is regulated to <=300ppm. In order to obtain polyolefin-based preliminary foamed particles satisfying the conditions, the amount of the inorganic dispersing agent attached to the surface of the polyolefin-based preliminary foamed particles is reduced by cleaning with an aqueous solution (e. g. an acidic aqueous solution of chlorous acid, hypochlorous acid, hydrochloric acid, nitric acid, etc.) capable of dissolving the dispersing agent.  The preliminary foamed particles are obtained by releasing a water dispersed material comprising polyolefin-based resin particles, an inorganic dispersing agent and a volatile foaming agent at a temperature near the melting point of the resin particles under pressure not lower than steam pressure of the foaming agent and not higher than the pressure in a pressure container.
