Title: Revolving speed controller for work in cam grinder
Inventor: IIDA WATARU
IPC: B24B19/12
Filed: 1978-06-20
Abstract: PURPOSE:To control revolving speed of a work by means of a simple electric circuit by enabling to detect a plurality of speed change points by one comparator. CONSTITUTION:When a signal C1, indicating that a first cam CM1 has been indexed to a position to effect grinding, is output from a main control circuit 26, a signal is output from an AND gate, and thereby, a gate is opened. Then, data of a calibration angle alpha1 preset in a digital switch are given to a comparator through a pass line. When a cam shaft 20 rotates further, the shaft rotates by the calibration angle alpha1 after an original point signal ZDS is sent out of a pulse generator 25. When a grinding point P comes to a bottom point BO, counted value of a pulse counter becomes alpha1, and it is detected by the comparator, then a coincidence signal is output from the comparator which, in turn, preset the pulse counter and set flip flop, and thereby, the angle, by which the grinding point is rotated from the initial bottom point BO on a base circle, is indicated.

Title: Water treatmtne apparatus
Inventor: TAKEDA TADASHI
IPC: B01D21/00
Filed: 1978-06-20
Abstract: PURPOSE: A simple-structure water treatment apparatus capable of exactly injecting a chemical  liquid into tank according to the flow rate of original water, consisting of a mixing tank in which  original water supplied toward tangent direction is mixed with a chemical liquid injected from the  lower part and a flocs-forming tank integrally provided so as to lead it to the upper part of the  mixing tank without movable mechnism.   
     CONSTITUTION: The original water is injected into the swirling room of the mixing tank 5 in the  direction of arrow mark so as to produce a swirling movement along the inside wall of the  chamber 7 and then directed to the outlet 10 at the central part, whereby a negative pressure is  produced near the inlet 9 for chemical liquid by a centrifugal effect of the swirling flow, resulting  in the suction of the chemical liquid 1 in the chemical liquid tank 2 into the chamber 7 through  the injection pipe 3 and the check valve 4, where the suction amount is controlled according to the flow rate of original water. And, the original water and the chemical liquid 1 are rapidly mixed  together inside the chamber 7 and then flowed through the outlet 10 and the tank 5 into the flocs- forming tank 11 having a sufficiently large capacity. Then, the flow rate of the mixed liquid  inside the tank 11 is lowered and the treated water with flocs so formed is introduced from the  exhaust port 12 into a sedimentation basin.

Title: Detecting and amplifying circuit
Inventor: HIRATA MASAKI
IPC: G11C11/419
Filed: 1981-05-19
Abstract: PURPOSE:To make the operation at a low input voltage and a low power consumption possible, by providing an integrated capacity consisting of a pair of MOS transistors which have gates connected to cross connection point of flip flops, and short-circuited between sources and drains and connected to a clock signal source. CONSTITUTION:When the voltage at a point A in the high voltage side is higher than a threshold voltage, an MOS transistor TR13 is inverted, and the capacity becomes proportional to the gate area. A TR14 which has the gate connected to a point B in the low voltage side is not inverted because the gate voltage is the earth potential, and no capacity is formed between the gate and the source and between the gate and the drain. When a clock phi3 is applied under this state, the side at the point A where the capacity is formed is boosted, and the side at the point B is not boosted. Since the gate of a TR8 which has the drain connected to the point A is in the earth potential, the electric charge at the point A is not discharged. Consequenctly, a logic circuit in the next stage is driven easily even with a low voltage input. Further, since the low voltage side is not boosted, a wasteful power consumption is prevented.
