Title: Drive controller of dc motor
Inventor: TANAKA SHIGERU
IPC: H02P7/292
Filed: 1983-03-08
Abstract: PURPOSE:To hold a basic power factor always at 1 and to remove harmonic waves by supplying the high frequency voltage of the constant voltage value outputted from a circulating current type cycloconverter through a phase advancing capacitor and a power converter to a DC motor. CONSTITUTION:A circulating current type cycloconverter CC inputs AC voltage and generates a high frequency voltage of frequency f*C. A phase advancing capacitor CAP generates a high frequency reactive power for compensating the variation in the reactive power of a power receiving terminal. A high frequency voltage is supplied through a separately-excited converter SS to DC motors DCM1, DCM2. At this time, the cycloconverter CC controls so that the peak value VC of the high frequency coincides with the command value V*C, and the converter SS is controlled so that the output current IDC coincides with the command value I*DC.

Abstract: PURPOSE: To monitor the amt. of sludge in a settling pool with high accuracy by analyzing such data as the amt. of inflow sewage, the amt. of return sludge, the amt. of excess sludge and the amt. of sludge drawn out of the pool according to a simulation model.  
     CONSTITUTION: Sewage is reacted with microorganisms in an aeration tank, and the resulting mixed liquor is fed into settling pool 10 through pass 11 and divided into vertically flowing portion A and laterally flowing portion B with flow regulation plate 12. In portion B the flow becomes gentle, sludge is settled, and the supernatant is discharged through trough 14. On the other hand, settled sludge D is scraped with scraper 13 and shifted to hopper 10a. By analyzing the amt. of the inflow sewage, the concn. of the mixed liquor, the amt. of sludge removed from the pool, the amt. of sludge returned from the pool to the aeration tank and the time required to settle solid matter in the pool according to a similation model, the amt. of sludge settled in the pool is calculated. Thus, the tank and the pool can be controlled so that they are fit for the inflow characteristics of sewage.

Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To improve the system performance by allowing a controller to read data from another flash memory while writing data in an arbitrary flash memory to shorten the processing time. SOLUTION: In a flash disk system, a system is designed so that, while a controller 10 executes an operation writing data DATAW equivalent to one page with respect to a certain arbitrary flash memory (for example, FM1), the controller executes a read access with respect to another arbitrary flash memory (for example, FM0) in a period tWB by using the period tWB when the flash memory FM1 is in a busy state because of the operation writing data in the memory to read out data DATAR equivalent to one page from the flash memory. Thus, the system performance is improved by shortening the processing time.

Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory of a control system which can make narrow a threshold distribution of a memory cell in a data erase state. SOLUTION: Based on a local self boost(LSB) system, erase threshold distribution of a cell is set at higher side of a readable range in an erase state to be made sufficiently narrow. Batch write in is carried out for each block of a memory cell array which is to be erased (S11), and thereafter soft erase is carried out for each block with a predetermined voltage as a start voltage (S12). The threshold of the cell is compared with a decision reference value (S14) through an erase verify reading operation. When the threshold of the cell fails to reach the decision reference, value, soft erase is repeated (loop S15). The predetermined voltage of the soft erase is varied from the start voltage. When the thresholds of all the cells reach the decision reference value, the soft erase is completed.

Filed: 1988-02-20
Abstract: PURPOSE:To accurately measure a flow rate, by generating a clean Karman vortex by preventing the generation of a trailing vortex from the joint of a vortex generator and a housing. CONSTITUTION:A point 7 is formed so that the angle theta1 formed by the main body side surface 3a of a vortex generator 3 and the inner surface 7a of the joint 7 becomes equal to the angle theta2 formed by the main body side surface 3a and the upper wall inner surface 2a of a housing 2. The joint 7 of the vortex generator 3 is slid up and down by adjusting a shim 26 so as to set the difference (h) in level between an upstream corner part 8 and the upper wall inner surface 2a of the housing 2 to + or -0.1mm or less and the housing 2 is fixed by a screw 25. At this time, since the inner surface 7a of the joint 7 is formed so as to become equal to the upper wall inner surface 2a of the housing 2 in a gradient, both surfaces can be easily positioned within the same plane. By this method, the generation of a trailing vortex 9 from the upstream corner part 8 is eliminated and the generation frequency of a Karman vortex can be accurately detected and a flow rate can be measured with good accuracy.
