Title: Semiconductor storage
Inventor: AIKAWA TADAO
IPC: G11C11/401
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To make a sure reflesh operation so as to be performed without the increasing of the occupancy area of a power source part and the increasing of power consumption due to the providing of plural power source generating circuits by performing the refresh operation in comformity with delays of operation timings due to voltage lowerings at the time of a refresh while delaying prescribed signals only at the time of the refresh. SOLUTION: However respective power source voltages are lowered than prescribed levels due to the shortage of current abilities of power source parts and operating speeds (level changes of signals) are lowered at the time of a refresh operation, operation timings are made to coincide with these delays (or are delayed) by applying a delay time larger than a delay time at the time of a normal access to output signals prepz and lez of a precharge control circuit 5 and a sense amplifier (S/A) control circuit 10 so as correspond to these delays. Thus, the refresh operation can be matchet with the delays of operation timings caused by shortages (voltage lowerings) of current supplying abilities of the power source parts at the time of the refresh operation.

Abstract: PROBLEM TO BE SOLVED: To make stable treatment possible over a long period of time by providing the subject device with a sensor for detecting a change in the sewage level in a treating vessel and controlling the rate of the air to be supplied from an air supply pipe to the sewage in the treating vessel according to output of this sensor. SOLUTION: Night soil is mixed with toilet paper in a J-shaped pipe 3 past a connecting pipe 2. The night soil flows over to a stirring vessel 1 from this J-shaped pipe 3 when the amt. of the night soil increases. This night soil is pre-decomposed by the air supply from a first air supply pipe 5. At this time, the air supply rate of a first blower 7 is controlled according to the output of a first pressure detecting section. The air supply rate is lowered by suppressing the electricity supply rate by a control circuit when the night soil level in, for example, the stirring vessel 1 is low.

Filed: 1986-09-19
Abstract: PURPOSE:To speed up a system by varying the operation clock period of the system in accordance with data processing operation time. CONSTITUTION:When a data processing circuit 5 starts its operation at the timing of a clock CLK0 from time t0 and ends its operation at time t1, the end of the processing operation at the time t1 is detected by a processing end detecting circuit 6. A processing end signal is fetched from the circuit 6, a period clock CLK1 is fetched from a clock composing circuit 3 in accordance with the processing end signal generating time t1 and checked at its pulse width by a pulse width checking circuit 4 and the checked signal is supplied to a data processing circuit 5. Since the operation end time t1 is faster than the rising time t2 of the clock CLK0, a clock CLK1 having a period shorter than that of the clock CLK0 is fetched. Thereby, the succeeding processing operation start is at time t6 and the processing operation is started at the timing faster than that of an ordinary device. Consequently, the succeeding processing operation starting time can be quickened and a high speed system can be attained.
