Title: Recycling method for bentonite liquid
Inventor: EMORI SHOICHI
IPC: B01D21/01
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To recycle bentonite liquid by a method wherein a small quantity of polyacrylic acid or citric acid is added to bentonite slurry in which earth and sand are suspended to cause earth and sand held in the slurry to be released and thereafter caustic soda is added to the bentonite liquid to restore the capability of holding earth and sand of the slurry. SOLUTION: Bentonite liquid is used to prevent the ground from being collapsed or prevent the penetration of underground water in the construction of continuous underground walls or the construction of waste water shields. When earth and sand are mixed into the bentonite liquid and performance of the liquid falls, in order to restore the performance of the liquid, polyacrylic acid or citric acid or salts thereof are added to the bentonite waste water in which earth and sand are suspended. Thus the earth and sand held in the waste water are released so that the earth and sand are settled under a liquid phase. The earth and sand are then removed from the bentonite liquid and caustic acid is added to the liquid to adjust the viscosity thereof so that the capability of the liquid of holding earth and sand can be restored and the liquid is recycled.

Title: Method for laminating dye lb film
Inventor: MIYADERA TOSHIYUKI
IPC: B05D1/20
Filed: 1990-04-23
Abstract: PURPOSE:To certainly laminate a dye LB film inferior to close adhesiveness and to allow the laminated dye LB film to develop predetermined optical characteristics by laminating the dye LB films requiring annealing treatment after film formation to a substrate from the first layer to the K-th layer and laminating dye 18 films good in mutual close adhesiveness thereon in a mutually adjacent state. CONSTITUTION:For example, in an optical recording medium in the case of N=3 and K=1, at first, the first dye LB film F1 is formed on a substrate 10 using a dye D-1 being an annealing required dye. Annealing treatment for forming a stable J-association wherein the peak of an absorption spectrum is further shifted toward a long wavelength to become steeper is applied to the dye LB film F1. The second and third layers are laminated to the dye LB film F1 using dyes D-2, D-3 but, since the dye D-3 is a lamination limiting dye forming a layer on which a dye LB film due to other dye can not be laminated, the second dye LB film F2 is laminated on the dye LB film F1 using the dye D-2 and, next, the third dye LB film F3 is laminated using the dye D-3.

Title: Film capacitor and manufacturing film thereof
Inventor: SATO KATSUMI
IPC: H01G4/32
Filed: 1992-04-24
Abstract: PURPOSE:To protect a film capacitor against corrosion as much as possible so as to prevent, it from deteriorating in capacitance due to corrosion by a method wherein ceramic oxide is evaporated on an aluminum thin film. CONSTITUTION:An aluminum thin film is evaporated on a film base F1 through an aluminum evaporator 16. Furthermore, oxides of one or more elements selected out of Si, Ti, Zr, Sn, Y, and indium-tin oxide are evaporated thereon as much as 0.1 to 10mg/m<2> preferably 0.3 to 3mg/m<2> through a ceramic evaporator 17. By this setup, ceramic oxide adheres concentrating on defective points (kinks, steps, others) imperfect in atomic arrangement on the surface of the aluminum thin film, so that the aluminum thin film can be locally enhanced in withstand voltage and improved in resistance to corrosion and breakdown strength at defective points. Therefore, 2 corona discharge hardly occurs between metal thin films, and the metal films are less corroded, so that a capacitor of this design can be elongated in service life.

Title: Controller for heat pump type hot water supplier
Inventor: MATSUMORI MASATO
IPC: F24H1/00
Filed: 1981-07-08
Abstract: PURPOSE:To obtain such a control for assisting heating when heating capability of freezing cycle is relatively small and to reduce heat leakage when the heating capability is relatively large by a method wherein a remaining time before a preset limit time for supplying power to an electric heater is set automatically in accordance with a preset temperature. CONSTITUTION:The electric heater 4 is provided in a hot water tank which is heated by the freezing cycle 1 having a compressor 9 and a fan motor 10. The water in the tank is heated to a temperature T1 by the freezing cycle 1. Thereafter, a time ta required for heating the water in the tank to a preset temperature Tf by means of the heater 4 is calculated in an operation circuit 20, and a difference (8-ta) between the operation time of the hot water supplier and said time ta is set in a time limit mechanism 15. The preset temperature Tf is being stored in a memory circuit 21 after a midnight power source 8 is turned OFF. When the heating performance of the freezing cycle 1 is relatively small and further the temperature does not reach T1 after an operation for the time of (8-a), the time limit mechanism 15 makes a relay 16 to operate and stops the operation of a circulation pump 3 and the freezing cycle 1, so that the heater is supplied with power. If the temperature reaches T1 after an elapse of (8-a), a thermostat 5 detecting temperature of water at an inlet of the pump 3 opens so as to stop the operation of the pump 3 and freezing cycle 1, thereby supplying power to the heater 4 through the time limit mechanism 15 when the time (8-a) has elapsed.

Title: Oscillation circuit
Inventor: OHARA JUNJI
IPC: H03K3/0231
Filed: 1992-04-27
Abstract: PURPOSE:To realize an FM modulator for wide oscillation band, high S/N and low secondary distortion by dividing the load resistance of the oscillation part of a circuit and attenuating the input amplitude to an output amplifier. CONSTITUTION:The signal current of an input signal Iin is propagated as the collector current of TRs Q6, Q7 by a current mirror circuit. The potential difference between the base and the emitter of the TR which is turned on is approximated to a fixed value Vbe, and the base potential of Q5 becomes Vec-3Vbe; the emitter potential becomes Vcc-4V when Q4 is turned off and Q5 is turned on in an initial state. The base potential of Q4 becomes Vcc-3Vbe-DELTAV. The emitter potential V4E of Q4 is lowered by the discharging by Iin, and Q4 is turned on and Q5 is turned off in the case of V4E=Vcc-4Vbe-DELTAV. At this time, the flow of current is stopped in the collector of Q5, then, the potential becomes Vcc-3Vfe+DELTAV as the current is increased and Q5 is turned on. Subsequently, these actions are repeated. The frequency (f) at this time becomes f= Iin/(4XC1XDELTAV). R5 and R6 are divided into R5a+R5b, R6a+R6b, respectively, and the input amplitude Va to an output amplifier is attenuated to Va=DELTAVXV5b/(R5a+R5b)=DELTAVXR6b/(R6a+R6b).

Title: Digital level sensor
IPC: G01F23/00
Filed: 1992-03-18
Abstract: PURPOSE:To display the true level of a liquid on a digital displaying section by correcting both the differential pressure between a high- and low-pressure receiving sections and the specific gravity of the liquid. CONSTITUTION:Since both the pressure Pa corresponding to a height (a) and the pressure Pb corresponding to the value (b) are applied to a level sensor main body 5, the accurate level of a liquid can be displayed by calculating and eliminating in advance the value (Pa-Pb) by means of an arithmetic section in the main body 5 as a fitting position correcting function. In addition, since the liquid level remarkably differ among different objects to be measured even when the applied pressures are the same, the accurate level of the liquid can be displayed, since a difference in density or specific gravity can be corrected by inputting the specific gravity or the inverse number of the specific gravity by using the function corresponding to the liquid. Moreover, the value is calculated at the arithmetic section in the main body 5.
