Title: Treatment of organic sewage
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/12
Filed: 1989-11-15
Abstract: PURPOSE:To obtain a sludge treatment method to decrease excess sludge by subjecting org. sewage to a solid-liquid sepn. after an aerobic biological treatment, then making the separated sludge alkaline and agitating and stagnating the sludge for a prescribed period of time and supplying the sludge to an aerobic biological treatment stage to lower the pH of the sludge. CONSTITUTION:The sewage 1 passes thereof an aeration stage 2, flows into a solid- liquid sepn. stage 4 and a part of the separated activated sludge 5 is made into the excess sludge 7. The remaining greater part is added with an alkaline agent 9, such as NaOH, to have about pH9 to 12 alkalinity. The sludge is introduced to an agitating tank 10 and is agitated for about 2 to 60 minutes under such conditions; thereafter, the sludge is recycled to the aeration stage 2. The extracellular polymers of microorganisms are produced when the recycled activated sludge is made alkaline and the eluted biopolymers are metabolized to the activated sludge by the microorganism in the aeration stage 2. A certain change arises in the metabolism of the microorganisms and the propagation rate decreases if the cycle of making the activated sludge alkaline, then returning the sludge to low pH is repeated. The treating method for the org. sewage which drastically decreases the amt. of the excess sludge to be generated is obtd. by this method.

Title: Semiconductor memory
Inventor: SUNAMI HIDEO
IPC: H01L27/10
Filed: 1990-11-02
Abstract: PURPOSE:To increase the electrode area without increasing the plane area and also increase strength against alpha ray by employing the side wall part of a groove made in an Si substrate as a plate and employing an electrode burried in the groove through an insulating film as the main part of a capacitor electrode for accumulating information. CONSTITUTION:A low resistance layer having same conductivity type as an Si substrate is provided at the side wall part of a groove 17 made in the Si substrate 10, and the resistance layer is employed as a plate 8 whereas an electrode burried in the groove is employed as a capacitor electrode 20. A capacitor 1 comprises a capacitor insulating film 18 and two electrodes, i.e., a capacitor electrode 19 and the plate 8, sandwiching the capacitor insulating film 18. If the plate 8 is same type as the Si substrate 10, i.e., p-type, the capacitor electrode 19 has positive potential. Consequently, the concentration of p-type impurity must be high enough to prevent formation of depletion or inversion layer on the surface of the plate 8 at the maximum potential. By such arrangement, capacitor area can be increased without decreasing the thickness of the insulation film even if the memory cell is made finer.

Title: Detection circuit for potential sensor
Inventor: HORI KAZUTO
IPC: G01R29/12
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain a detection circuit by which the contamination of a sensor probe is prevented or excluded. SOLUTION: A detection circuit 50 for a potential sensor is provided with an external-signal input terminal TEX. A signal from the external-signal input terminal TEX is input to a high-voltage amplifier circuit 55 via a changeover device 80. The high-voltage amplifier circuit 55 is provided with a function to output a high-voltage signal whose potential is equal to that of an object to be measured and with a function to generate a voltage whose polarity is opposite to that of the potential of the object to be measured. Then, a signal which can generate the voltage whose polarity is opposite to the potential of the object, to be measured, from the high-voltage amplifier circuit 55 is given, from a control circuit 70, to the external-signal input terminal TEX. The changeover device 80 is changed over to the side of the input terminal TEX.  Thereby, the voltage whose polarity is opposite to that of the potential of the object to be measured is applied, via a line 60, to a sensor probe 40. As a result, dust such as a toner or the like which is stuck to the sensor probe is scattered.

Title: Temperature controller for hot roller
Inventor: ONDA KIYOSHI
IPC: D02J1/22
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To solve the problem of a hot roller temperature controller that is made switchable to an emergency control mode based on the detections by a plurality of embedded sensors in which the temperature detection becomes impossible by any sensors when a trouble occurs in a transmission system, for example, a rotary trans, or the like, and the hot rollers resultantly must be stopped until the restoration, thus filament yarns continuously extruded must be wasted and productivity is lowered. SOLUTION: In this hot roller system, the filament yarns are guided, as it is wound around the outer periphery of the roller, and are heated by the hot roller R. In this case, the temperature controller 1 is equipped with a switching means 20, an emergency detection means 21, and a correction means 22. When emergency at the embedded sensors is detected by the emergency detection means 21 and a heater-controlling mode is switched from a mode based on the detected values by the embedded sensors so another mode based on non-rotary sensors, the detection values after the switching are corrected by a correction means on the basis of the bias between both kinds of sensors in the normal state.

Title: Turning cascade amplifier with rail-to-rail same phase range
Inventor: UEIICHIYAN SU
IPC: H03F1/22
Filed: 1988-11-22
Abstract: PURPOSE: To reduce the crossing distortion by forming a high feedback amplifier circuit causing changes in a bias current generated when a pair of inputting devices are disconnected. CONSTITUTION: When a contact point 50 starts rising because of the comparatively low voltage of an input terminal 24, this starts to turn off a transistor 80 to allow more current to flow through a contact 65 and a transistor 86 through a transistor 82. Consequently, the gate of a transistor 62 reflected to the gate of a transistor 74 is slightly pulled up. Since the transistor 74 is provided with gate voltage independent of a drain voltage, further more current are made to flow through the transistor 74 to attract furthermore current through a transistor 70 to reduce the voltage of the contact 50. Consequently, the high feedback amplifier circuit causing the change of the bias current generated when a pair of the inputting devices are disconnected is formed. Thereby, crossing distortion is made comparatively low.

Abstract: PROBLEM TO BE SOLVED: To detect leakage of fuel from a BWR(Boiling Water Reactor) with high sensitivity by a structure wherein the core water on the inside of a lifted fuel rod is sucked therefrom and fed to a gas separator. SOLUTION: Reactor core water is fed through the action of a pump 13 into a mast 7 and flows around and into a fuel assembly 9. It is then pumped up through a pump 13 to a gas separator 22 where the pressure of gas existing in the core water is lowered. Consequently, the solubility of gas in the core water is decreased and the gas is separated from the core water 12. In order to separate the gas in a sample effectively, the core water 12 is atomized through a spray 26 in combination with passage through the gas separator 22. The separated gas is mixed with a working gas existing in the separator 22 and sucked through a gas circuit 27 into a measuring chamber 28 where production of fission product is analyzed by means of a detector.
