Title: Charge coupled device
Inventor: KOZONO TOSHIYUKI
IPC: H04N5/372
Filed: 1988-04-08
Abstract: PURPOSE:To decrease the plunge of pulse applied to reset gate electrodes and a CCD gate electrode, by connecting the high-concentration impurity layer of a charge-coupled signal charge detecting part through the gate part of a detecting switch element and a low-concentration impurity layer. CONSTITUTION:The high-concentration impurity layer 6 of an electric charge detecting part 3 is connected through the channel part 8 of an adjacent gate electrode 4 and a low-concentration impurity layer 12. Therefore, the reference electric potential of the electric charge detecting part 3 is never affected by the changes of the voltage of a reset drain 5 and the high-concentration impurity layer 6 has no coupling capacity with the adjacent reset gate 4 and an output gate 2. This suppresses the plunge of pulse applied to the reset gate 4 and the influence of the pulse applied to CCD gate electrodes 1 plunging through the output gate 2 to obtain a stable electric charge detecting device.

Title: Refreshing device for dynamic ram
Inventor: HIRAUMA KOICHI
IPC: G11C11/34
Filed: 1987-04-09
Abstract: PURPOSE:To make a bus cycle longer, by delaying the timing of operating a refreshing (REF) timer and making the interval between refreshment requests just before and just after resetting shorter. CONSTITUTION:When a reset signal is inputted to a delaying circuit 4 through an internal bus line 101 and a delay takes place in the circuit 4 at a time t1, a REF timer 3 starts counting clear and counting start in synchronism with the delayed waveform at time t2 and sends a request signal to a memory cell 2 from the REF timer 3. The memory cell 2 counts up whenever REF is performed in accordance with the request signal and the entire memory cell 2 is refreshed by plural times of operations. Then the interval between the refreshment request just before resetting and the refreshment request just after resetting becomes shorter (15-30mus) and the bus cycle becomes longer. Therefore, interruption of a bus cycle being executed is reduced and the accessing time between a master and slave can be shortened.

The washing water flows from the lower side of the bed 2, overflows from the upper part thereof and flows into the direction of a check valve 6. The turbidity thereof is detected with a turbidimeter 8. The change of this signal with time as shown in the figure. This change is detected by an operator 9, which operates a limiter 10 by a negative signal that goes negative while the turbidity is decreasing, thereby operating a comparator 11. When it lowers below the set value D 0  of a setter 12, a washing end signal is applied to the device 14. The device 14 emits a command to the valve 3, etc. and the pump 13, thereby ending the washing. The basin 1 again starts filtering operation.
