Title: Method for accelerating separation of water from coal slurry in bunker
Inventor: KATSURA YUTAKA
IPC: F23K1/02
Filed: 1979-03-27
Abstract: PURPOSE: To enable the grab-unloading of powdered coal from a coal ship, by heating a slurry of powdered coal in the first tank, cooling in the second tank with cold water spray, precipitating the powdered coal rapidly, and removing the separated water layer.  
     CONSTITUTION: A powdered coal slurry containing, e.g. 60W70% of coal is  pumped from the storage tank 5 of a coal loading port into the first tank 1 in a coal ship, and is heated with a heating coil 2. The heated slurry is pumped to the second tank 6, where it is cooled with cold water spray sent from a cold water tank 12 and is separated into a water layer and a coal layer in a short time. The upper water layer is drained from an exhaust pipe 9 to a recess 14, cooled e.g. by the heat exchange with sea water, and recycled to the cold water tank 12.

Title: Interface circuit
Inventor: KUROKI KUNIHIKO
IPC: G06F3/00
Filed: 1978-03-31
Abstract: PURPOSE: To simplify the circuit constitution and to increase the maintenability and reliability as the entire system, by performing the answer back of the input and output unit of the computer through the use of the operation conditional signal and the apparent answer back signal.  
     CONSTITUTION: If the answer back AS is not needed to the computer B from the input and output device C, when the write-in instruction signal 8 is given from the computer A, the data conversion circuit 1 converts the write-in data 7 1  to 7 n  in n-bit into serial signal to deliver it as the input data 9 of C. When the circuit 1 outputs the delivery end signal 10, the one shot circuit 2 produces the output 11 of time width T and the output pulse 12 is produced via the edge detection circuit 3. On the other hand, since no AS is needed to B by the data 9, the operation conditional signal of C is at "1" and the signal from B can be fetched at any time. The pulse 12 is given to B as apparent AS 16 via the AND circuit 5 and the OR circuit 6, and B gives the write-in data being the operation instruction of the new input and output device to the circuit 1.

In SA4, while an optical path length difference DEF and the peak level and the peak level of every beam of reflected light are being changed by an optical branching filter, a data set for learning is classified into data sets for universal evaluation. In SA5, while the data set for learning is being used, the learning of the neural network NN is performed, and the learning is repeated until a teacher signal and an output error become small. In SA6, the peak level of reflected light is computed. In SA7, the neural network NN is evaluated for every optical path length difference DEF.

Title: Gate controlling circuit
Inventor: MORIYA FUMIYASU
IPC: H02M1/06
Filed: 1980-03-25
Abstract: PURPOSE:To obtain the gate controlling circuit of a high efficiency at a low cost by a method wherein the stored charge of a capacitor is discharged through a thyristor and a pulse transformer and a GTO is turned off using the pulse current which is induced at a secondary winding by said discharge. CONSTITUTION:The GTO is turned to ON by giving an ON position to a transistor S1. At the same time, the capacitor C is charged by voltage E1 and E2. Then, for the purpose of giving an OFF position to the GTO, the transistor S1 is turned to OFF and the transistor S2 to ON position. As a result, the charge on the capacitor C is discharged through the intermediary of the thyristor T2 and the pulse transformer GT, and through the aid of this discharge, the GTO is turned OFF by the pulse current generated at the secondary winding. When a power source E2 gives a negative bias to a gate G, the thyristor T1 is turned OFF by the drop of the forward current on a diode D1 and at the same time, the thyristor T2 is turned OFF by the current generated at the primary winding.

Title: Variable gain amplifier circuit
Inventor: OOTSUKI YOSHIKI
IPC: H03G3/00
Filed: 1983-03-08
Abstract: PURPOSE:To obtain a variable gain amplifier circuit where stray capacitance is decreased and an output with less deterioration in a high frequency is extracted by using an electronic switching element whose one end is connected to ground directly. CONSTITUTION:One end of switches S1-Sm made of MOS or the like is connected in common and grounded and the other ends are connected in common respectively via resistors R1-Rm. The common connecting point of the resistors R1- Rm is connected to an input terminal 1 via the resistor R1 and also connected to a positive input terminal of an amplifier 2. Since the switches are so constituted that one ends are connected to ground, an input stray capacitance Cji exists at a drain D of the other end by connecting resistors R1-Rm thereto as shown in equivalent circuit of a single switch, but an output side stray capacitance CJO between the source S and ground is short-circuited and equivalent to zero. Since only one stray capacitance exists for one switch in this way, the value of stray capacitance is halved nearly.

Title: Two members attaching structure
Inventor: UENO KEISUKE
IPC: F16B5/10
Filed: 1994-03-09
Abstract: PURPOSE:To provide two members attaching structure which is hard to break and easy to attach by attaching the fellow members, making use of the boss part projected on the surface of one side plastic member. CONSTITUTION:A thin claw part 4 is extended roughly in the direction of the tangent of the periphery of a boss part 3 from a coupling section which has a specified length in the axial direction of the periphery of the boss part 3, and also the top side 4a of the thin claw part on the side of the head 3a of the boss part is inclined gradually downward. Hereby, when inserting the boss part 3 into a through hole 5, the thin claw part 4 is transformed toward the surface of the periphery of the boss part, receiving the force in the direction of crossing the axial direction of the boss part from the inwall end of a through hole 5 through the top side 4a of the thin claw part. After insertion into the though hole 5 of the boss part 3, the thin claw part 4 returns elastically, and the bottom side 4b of the thin claw part 4b and the second member body 2 abut on each other at an abutment section E, and the two members are locked. This way, when inserting the boss part 3, the thin claw part 4 is easy to flex due to the thickness, and is hard to flex after insertion since the length in the axial direction of the boss part 3 of the coupling section between the boss part 3 and the thin claw part 4 is relatively long, so two members attaching structure, which fulfills both properties hard to breake and hard to slip out and also does not mar the easiness of mounting, can be gotten.
