Title: Automatic water-supply method and device therefor
Inventor: SATO KOICHI
IPC: F04D15/00
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To automatically control the water-supply pressure of a pump even if the water-supply pressure drops below the stopping pressure of the pump through the setting of the starting pressure and the stopping pressure of the pump only one time, by successively updating the stopping-pressure value of the pump to a pressure value just after the stoppage of the pump every time the rate of change in water-supply pressure gets smaller than a reference value. SOLUTION: A water-supply pressure P' just after the forcible stoppage of a pump is stored in a memory, and a water-supply pressure P" after the lapse of a predetermined unit time ΔT is detected. The difference ΔP between the water-supply pressure P" and the water-supply pressure P' just after the stoppage of the pump are calculated, and the rate of change ΔP/ΔT in the unit time ΔT is obtained. The value of the rate of the change is then compared with a predetermined reference value (a) for the determination of its relative largeness or smallness. If the rate of change ΔP/ΔT is smaller than the reference value (a), the value of a stopping pressure P2 of the pump is updated to the water-supply pressure P' just after the forcible stoppage.  The above process from the initial setting is repeated to successively update the stopping pressure every time the rate of change gets smaller.

IPC: G06T7/00
Filed: 1989-03-02
Abstract: PURPOSE:To easily develop an image processing device by setting frequencies accumulated at every bit pattern as the degree of contribution of each bit pattern on a designated category. CONSTITUTION:An A/D conversion circuit 16 is a circuit to make a photographed image into a bit map, and bit-mapped image is stored in a VRAM 17.

Title: Data base accessing system
Inventor: MOTODA TOSHIHIRO
IPC: G06F12/00
Filed: 1990-03-02
Abstract: PURPOSE:To execute a routine data base access processing at a high speed by sending an identifier at the time point of an access, and also, storing and reutilizing a dynamically generated data base access exclusive routine (AR). CONSTITUTION:In the case of a first data base access, a control part 11 sends its own identifier to a data base (DB) accessing part 13 in the part where a data base access is necessary. The DB accessing part 13 retrieves an AR 15 corresponding to the identifier. In this case, since it is a first access, its AR does not exist, therefore, from the DB accessing part 13, an answer that there is no corresponding one is returned to the control part 11, and the control part 11 sends a data base accessing instruction sentence to the DB access part 13. Also, the DB accessing part 13 instructs to generate the AR by using its instruction sentence as a parameter to a data base managing system (DBMS) 14, and the DBMS 14 generates the AR 15 and stores it. Finally, by executing its AR 15, the data base access is executed. In such a manner, the routine data base access can be executed efficiently.
