Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To enable catching scum floating on the surface of the water into water at the same time on aeration to subject it to crushing treatment by installing two guide plates opposite to both sides of a screw. SOLUTION: A screw 4 is provided on the tip of a hollow shaft 1 subjected to rotary driving by a motor 3. And two guide plates 5, 5 are fitted, through a stay, a support arm, or the like, to a support frame to which an aerator is fitted, an upper structural body of the aerator, or the like opposite to both sides of the screw 4 so that the upper ends thereof stick upward out of the surface of the water. Sewage is agitated by the rotary driving of the screw 4 to generate a water flow in the tip water area, and by this water flow, the sewage near to the screw is moved.  At that time, by the guide plates 5, 5, the quantity of the sewage sucked in from both sides of the screw 4 is decreased, thereby catching scum floating on the surface of the water together with the sewage near to the surface of the water above the screw 4 to crush it and preventing a vortex from growing on the surface of the water.

Title: Memory reading circuit
Inventor: UEMATSU AKIRA
IPC: G11C17/00
Filed: 1988-04-22
Abstract: PURPOSE:To obtain a memory reading circuit to stably read data by providing a precharge detecting circuit to detect large current supply to a bit line and a circuit to receive the detected signal of the precharge detecting circuit and temporarily hold a potential. CONSTITUTION:When bit lines 7 and 8 are switched, and large current is supplied from a sense circuit to the bit lines, a precharge detecting circuit 11 operates a holding circuit 12 between an output circuit 4 and an amplifying circuit 3, holds the data state of the output circuit 4, which is the one before the sense circuit supplies the large current, and simultaneously separates the amplifying circuit 3 and the output circuit 4. When the potentials of the bit lines 7 and 8 become higher, and the current supplied to the bit lines is reduced, the precharge detecting circuit 11 detects this, makes the holding circuit 12 into an OFF state, and links the amplifying circuit 3 and the output circuit 4. When the sense circuit is charged, the output circuit 4 is held and separated from a front step circuit, and when the charging of the sense circuit is completed, the holding is released, and the output circuit 4 is linked with the front step circuit. Thus, a meaningless deflection in the output circuit 4 can be suppressed, and the data can be read stably.
