Title: Diaphragm pump
Inventor: GEORUGU HAINRITSUHI RINDONAA
IPC: F04B43/073
Filed: 1984-12-24
Abstract: A positive displacement pump (310) utilizes at leastthree driven displacer valves (360,362,364) and a plurality of driving membranes (336,340,344) and at least one pumping membrane (316) to withdraw minute quantities of corrosive fluid from a drum (100) and discharge same to a delivery point (128). The pump (310) is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator (116) comprising pneumatic logic circuitry. The driven displacer valves (360,362,364) operate in a particular sequence to draw fluid into the pump body (312,314), advance same in succession through pumping chambers (318,320,322) within the pump body (312,314), and then discharge same at a constant rate of discrete pulses through an outlet port (332). The pulse generator (116) and logic circuitry provide the control pulses for operating the displacer valves (360,362,364) at the proper times in the operational cycle. The delivery characteristics of the pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.

Title: Method and device for cutting out specified amount of reclaimer
Inventor: YOSHINAGA SHIRO
IPC: B65G63/00
Filed: 1990-10-11
Abstract: PURPOSE:To enable cutting-out of specified amount of material in a process of cutting out raw material by compensating the lateral turning speed so that the cutting amount may become the standard amount according to the difference in amounts of broken and dropped raw material passed through a wheel bucket. CONSTITUTION:To a boom J a wheel bucket E is installed, and the bucket E is put in piled raw material P to scoop a certain amount of the material P while it is rotated, turned laterally and finely advanced. The amounts of raw material broken and dropped at a cutting-out stage after the passing of the bucket E just after the boom is turned rightward or leftward differ according to the mounting positions (left or right) of the bucket E and the mounting angle. The difference is obtained from the actual results. The turning speed of the boom J in the direction where the scooping amount is less is accelerated based on the turning speed thereof in the direction where the scooping amount is much. A specified amount of cutting out can be made accordingly.

Title: Dc motor driving circuit
Inventor: TABUCHI SADATOSHI
IPC: H02P7/288
Filed: 1987-10-29
Abstract: PURPOSE:To accurately apply a set voltage to a motor by controlling the terminal voltage of the motor to a set value. CONSTITUTION:When a voltage from an AC power source 10 is applied, a current flows to a heater 20 and a motor 70. When the terminal voltage of the motor 70 becomes a set value or higher, the output of a comparator 61 becomes 'L', and a bidirectional thyristor 40 is turned ON. Thus, a current full-wave rectifier by the heater 20, a rectifying stack 30 flows to the thyristor 40. If the terminal voltage of the motor 70 becomes the set value or lower, the thyristor 40 is again turned OFF, and a current is supplied to the motor 70. On the other hand, if a trouble occurs in a controller, the thyristor 40 becomes impossible to control. However, if the terminal voltage of the motor rises to the Zener voltage or higher of a constant-voltage diode 80, the thyristor 40 is turned ON, thereby cutting off the current supplied to the motor 70.

Title: Delay circuit
Inventor: KUROKAWA REI
IPC: H03K5/13
Filed: 1985-12-05
Abstract: PURPOSE:To control continuously a delay time with simple constitution by obtaining an output pulse signal having an optional delay time by the operation of a control circuit controlling an oscillation frequency of a voltage controlled oscillator, a counter and a gate. CONSTITUTION:An input pulse signal 1 is fed to a control circuit 6, which supplies a reset signal synchronously with the signal 1 to a voltage controlled oscillator 2 and a counter circuit 3. Since the oscillator 2 is controlled for the oscillating frequency by the control voltage, a signal from a counter output terminal 31 of the circuit 3 is controlled by the control voltage of the oscillator 2 and the signal 1. The gate circuit 5 selects the signal from the terminal 31 to obtain an output pulse signal 7 with a proper delay time. The delay time between the signal from the terminal 31 and the signal 1 depends on the oscillated frequency of the oscillator 2 and the frequency division ratio of the counter and the delay time of the signal synchronized with the signal 1 is controlled variably by the control voltage of the oscillator 2 continuously.
