Title: Forecasting correction control method
Inventor: YAMADA TETSUYA
IPC: G05D7/06
Filed: 1979-04-25
Abstract: PURPOSE: To make it possible to exercise excellent control over water distribution by forecasting and correcting a flow rate for one following hour by making use of the cumulative value of the actual flow and the forecasted cumulative value of the flow of distributed water up to the same time with regard to the distributed water control in a purification plant.  
     CONSTITUTION: Memory 11 is stored with data on the forecasted flow of distributed water of every hour as much as one day, and a signal showing the flow rate at tank outlet 7 is led to a controller by way of process input-output device 10 and input to integrating circuit 13. Then, the arithmetic of the cumulative value of flow rate comes into effect by a signal of every hour from clocking circuit 14 and the arithmetic result is sent to actual flow rate integrating meter 12. Here, forecasting correcting circuit 15 forecasts and corrects the flow rate for one following hour by using the cumulative value of the actual flow up to that point and the forecasted cumulative value of the flow rate of distributed water up to the same time. As a result, the overall outflow from the tank is controlled so as to flow the water into the tank evenly, so that excellent control over water distribution can be exercised without causing the water level of the tank to change greatly.

Abstract: PURPOSE:To enable an execution of a sealing work and an inspection work of air tightness in a dry condition by providing a plug sealing laying space and by fully shielding a radiation and radioactive substances. CONSTITUTION:After housing spent fuels in a laying space 5, a plug 7 is placed at an expanding step part 6. In this situation, a cylindrical member 23 provided in the plug 7, is pressed by a supporting device of the plug 7 against its spring action and therewith a protrusively engaging part 15a of a swinging member 15 is in a set-back condition. Accordingly by pulling out the plug 7 from the supporting device, the cylindrical member 23 is driven upwardly, so that the protrusively engaging part 15a of the swinging member 15 enters an intrusively engaging part 14 of an inner container 3, and consequently the plug 7 is firmly fixed to the inner container 3. An inner gas is sealed by a sealant 11 and also the plug 7 is prevented from floating up by an engaging of the swinging member 15 even when an inner pressure rises. Thereafter, an intermediate lid 29 and an outerlid 30 are closed to seal up the container completely.

Title: Semiconductor memory device
Inventor: NAKASE YASUNOBU
IPC: G11C11/34
Filed: 1986-03-07
Abstract: PURPOSE:To shorten the access time and to prevent a malfunction at the time of writing by connecting each bit wire drive load line to the common 1st constant current source through a diode individually connected and to the common 2nd constant current source through a resistance individually connected and connecting the resistance with diode connected to the side of the bit wire drive load line in parallel. CONSTITUTION:The connection point between the 1st and 2nd resistances Ri1 and Ri2 is connected to the cathode of the diode Di, and the 1st resistance Ri1 and the diode Di are connected in parallel. If the bit wire drive load line BDLi stands at a higher potential than other bit wire drive load lines, that is, in a time t1, the diode Di is conductive, and the bit wire drive load line BDLi is discharged by the constant current source IBLD1. In a time t2 when a double section state is present, the 2nd constant current source IBLD2 discharges. Thus the discharging time of the bit wire drive load line can be shortened, whereby the access time can be shortened and the malfunction at the time of writing can be prevented.

Abstract: PURPOSE:To match positions at high precision and simplify manufacturing process by exposing a photosensitive resin masked by the third electrode consisting of a conductive material foil with an aperture and then forming the second dielectric through the removing of the exposed part and perforation of the photosensitive resin. CONSTITUTION:A photosensitive resin film 15 of a predetermined thickness is pasted on the second electrode 12 side and a conductive material foil such as metal foil as the third electrode is pasted on the photosensitive resin film 15. Next, a photoresist 21 is coated on the conductive material foil so that the entire area of the third electrode 12 may be masked and exposed to light except an aperture 17 part to remove the exposed part. After these procedures, the aperture 17 is formed on the metal foil by etching and an overall exposure is carried out starting with the metal foil side. Consequently, only the photosensitive resin area corresponding to the aperture 17 is exposed to light due to the third electrode 13 as a mask. Then the photoresist 21 is immersed in an aqueous alkali solution, so that only the area adjoining the aperture of the third electrode 13 is removed. As a result, the second dielectric 15 having an independent aperture 16 is formed.
