Title: Controlling method of concentrating tank
Inventor: MIURA IKUO
IPC: G05B11/32
Filed: 1979-05-04
Abstract: PURPOSE: To obtain a relatively simple controller to perform a high-efficiency and stable automatic operation by improving feedback mechanism in coordinate control of feedback and feedfoward operations.  
     CONSTITUTION: A calculator 11 calculates theoretical inlet flow rate y 1 , by which a caluculator 12 determines the range of variation in inlet concentration and gives a value y 2 , by substracting a proper value set by a setter HC-6. A calculator 13 handles an output signal C s  from an outlet concentration regulator DIC-3, making its output span further proper, and gives a value y 3 . A calculator 14 adds the outputs y 2  and y 3  to provide y 4 . The output signal y 4  becomes the final operating quantity and is used as the set value for the raw liquid inlet flow regulator FIC-2, which compares y 4  with the flow of raw liquid found by a detector 2, and emits calculated signal to drive control valve 5 so that required inlet flow rate is maintained.

Title: Screw-system sand-sediment drawing device operation method
Inventor: OKAZAKI NOBORU
IPC: B01D21/24
Filed: 1978-05-08
Abstract: PURPOSE: To stop the operation of a screw immediately until the next operation time, when the rotational load of the screw at the beginning of its operation is lower than the preset value during its operation.  
     CONSTITUTION: In a city sewage treatment facility, the rotational force of electric motor 9 is transmitted to rotary shaft 10. Further, it is transmitted to screw 12 via gear box 11. As a means to detect the rotational load of screw 12, current switch 13 is connected to the power source of electric motor 9. Switch 13 functions to stop the operation of screw 12 during its operation when the rotational load of screw 12 is lower than the preset value (when the amount of sand-sediment is small). This eliminates wasteful operation of the screw and serves to save electric power.

Title: Core performance calculation method and device
Inventor: IWAMOTO TATSUYA
IPC: G21C17/00
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To enable a speedy and accurate calculation of inherent value and distribution of neutron flux by adopting an efficient neutron repetition analysis of finite step type while maintaining an advantage in the accuracy of an analytic polynominal node method. SOLUTION: A core of a nuclear reactor is divided into nodes and solving a diffusion method analytically by approximating a neutron source in the node with a plynominal method, whereby the distribution of neutron flux in the core is calculated. In this case, with a node average neutron flux if it is given, the flow of nuetrons at the boundary of nodes from the neutron flux distribution in the nodes is calculated accurately. A binding coefficient of finite difference type reproducing the flow of neutrons is represented by use of a neutron flux non-continuous factor. The neutron flux non-continuous factor is renewed for every repetition of outside source or every its upper repetition. According to the repetition calculation of inside neutron flux - outside source by use of the binding coefficient, the distribution of neutron flux in the core is calculated.  In this way it is possible to calculate an inherent value and distribution of neutron flux accurately in a short time.

Filed: 1992-02-05
Abstract: PURPOSE:To obtain a bright display by informatively converting the color data on the last end to a black color when the same data of adjacent plural numbers are lined. CONSTITUTION:This liquid crystal display consists of an X axis driver and a Y axis sdriver and these drivers are connected to a liquid crystal matrix and also singal lines transferring data to the Y axis driver are arranged.

For example, when Gs(green colors) are lined after Rs(red colors) are continued for three times, the third R is converted to BL(a black color) by the procession of a data working device. Thus, the same color having plural dots or an area having the same brightnesses is identified automatically and then an black outline is provided on the end.

Title: Produciton of ceramic tool
Inventor: TAKAMI AKIHIDE
IPC: C04B35/58
Filed: 1989-03-07
Abstract: PURPOSE:To obtain a ceramic tool improved in abrasion resistance and cutting speed by pulverizing beta-Si3N4 having a sialon layer on the surface thereof, mixing the prepared powder with Al2O3, forming the resultant mixture and calcining the formed compact. CONSTITUTION:alpha-Si3N4 is mixed with Al2O3 to provide a mixture, which is then heated to produce beta-Si3N4 having a sialon layer on the surface thereof. The resultant beta-Si3N4 is then mixed with Al2O3 and the obtained mixture of the beta-Si3N4 with the Al2O3 is subsequently formed and calcined to provide the objective ceramic tool. Since the mixture of the alpha-Si3N4 with the Al2O3 is heated by the above-mentioned method, the alpha-Si3N4 is transformed into the beta-Si3N4 and the sialon is simultaneously formed on the surface of the beta-Si3N4. Since the mixture of the beta-Si3N4 having the sialon on the surface thereof with the Al2O3 is calcined, wettability is improved to form a more solid solution of the Al2O3 in the Si3N4. Thereby, the calcined compact is densified to afford the ceramic tool improved in strength. Furthermore, the Si3N4 in the calcined compact is transformed into the beta-form, the resultant ceramic tool has a high strength.

Abstract: PROBLEM TO BE SOLVED: To obtain a light control device which is changed in transmittance by incidence of light and is easy to handle by laminating a thin-film solar battery element and electrochromic element, etc., on a flexible substrate and connecting these elements in series. SOLUTION: The light control device has the structure obtd. by laminating the thin-film solar battery element consisting of a first transparent electrode layer 2, p-type translucent non-single crystalline semiconductor layer 3, i-type translucent non-single crystalline semiconductor layer 4, n-type translucent non-single crystalline semiconductor layer 5 and second transparent electrode layer 6, the electrochromic material layer 7, an ion conduction layer 8 and a third transparent electrode layer 9 on the transparent flexible substrate 1.

Next, the thin-film solar battery element does not generate electric power any more when the element changes from the brightness to the darkness. The direction of the current is then inverted by the secondary battery applied from outside and the transmittance restore to the original value.
