Title: Memory control system
Inventor: IYOTA HIDEO
IPC: G06F12/00
Filed: 1987-01-28
Abstract: PURPOSE:To control in parallel a memory means via >=two memory control means and to ensure the flexible application of a memory control system, by performing the input/output control of the data on the memory means via each memory control means with reference to the indication signal applied to another memory control means. CONSTITUTION:When both memory controllers 221A and 221B try to give accesses to the same memory at a time, the higher priorities are given to the requests of channel processors 243 and 247 than those of CPU 241 has the higher priority than that given from the controller 221B and is given to both memories 211 and 213. This relationship is reversed for the assesses given to both memories 215 and 217. For instance, the memories 211 and 213 are used as the memories set at the local side of the controller 221A; while the memories 215 and 217 are used as the memories set at the local side of the controller 221B respectively. Otherwise these memories are used as those set at the remote side. Under such conditions, the priorities are given to the memories of the local side. In such a way, two memory controllers can control a single memory in parallel with each other. Thus the flexible application is possible with a memory control system.

Title: Water level controller
Inventor: KURODA YASUYUKI
IPC: G05D9/12
Filed: 1980-02-20
Abstract: PURPOSE:To realize a constant time during which a target water level is obtained regardless of the flow rate, by obtaining a presumed opening amount necessary for adjustment of a target water level by storing the control property of the water level control valve and then controlling the opening amount of the valve to the presumed opening amount to carry out a feedback control. CONSTITUTION:The water level control valve 4 is controlled by the controller 1. The controller 1 decides the valve opening amount theta based on the target water level command H and the flow rate detection value Q of the flow rate meter 9 provided to the water level transmitter 5 installed at the pump basin 6, and the amount theta is controlled to be set at the level under the target water level H0. Then a proportional integral/differential calculus PID control is given when the difference between the target water level and the real water level is the constant alpha1 or less; while a presumed opening amount is obtained when the difference is alpha1 or more. After this, the valve is kept at the presumed opening amount to observe the change of level for a prescribed time. In case the water level does not approximate to the target water level, a calculation is carried out again to set the valve again. Then a PID control is given the difference between the target and real levels is less than the prescribed value alpha2; while a presumed opening amount is calculated again when the real level becomes further away from the target level. In such way, the time during which the target water level is obtained can be set constant regardless of the flow rate of water.
