Abstract: PURPOSE: To provide a simple structure, scale-free, highly efficient electrolytic treatment equipment, a rotary shaft in the bath is provided with a number of alternate disk electrodes as anode and cathodes.  
     CONSTITUTION: Disk electrodes 2 arranged in the electrolytic bath 6 are used for electrolytic treatment of waste water. The disk electrodes 2 are alternately fixed to the rotary shaft 1 at proper intervals so that the disks 2 insulated from the shaft 1 and operate as anodes 3 and cathodes 4. Voltage is applied to the electrodes through insulated lead wire arranged to the shaft 1, while rotating the electrodes 2 at peripheral speed of about 1m/sec or more, preferably 5W20m/sec. When a number of electrode groups 5 are arranged in the direction of liquid flow, electrolyte is certain to stay in the electric field for enough time required for electrolytic treatment. When a number of electrode group 5 is arranged at right angle to the direction of liquid flow, or in vertical direction, a volume of treatment is made possible. The process prevents the surface of the electorode 2 from scale deposition and permits dissolved mixture to undergo an effective electrolysis, coagulation, and floating up.

Title: Semiconductor storage device
Inventor: OGURA ISAO
IPC: G11C11/4094
Filed: 1982-07-19
Abstract: PURPOSE:To make a memory cell large-capacity, by supplying a signal to one MOS transistor (TR) of a boosting circuit to boost a bit line. CONSTITUTION:A signal phi2 is supplied to the gate of a TR Q1 between a node N1 and a bit line 2. Information read out from a memory cell 1 to the bit line 2 is sensed and amplified by a sense amplifier 3. At this time, when information is 1, the bit line 2 becomes 1, but this level 1 is lowered. A voltage lower than a power source voltage VCC is supplied to the node N1 through the TR Q1, and a signal phi1 is inputted, and the node N1 is pushed up, and then, a TR Q2 performs the triode operation sufficiently to raise the level of the bit line to the level VCC. Next, the signal phi2 is pushed up, and the TR Q1 performs the triode operation to transmit the high potential of the node N1 to the bit line 2. Since the quantity of electric charge held in the cell is increased, the sense margin is improved.
