Title: Stack gas desulfurization device
Inventor: OBATA KOUZOU
IPC: B01D53/81
Filed: 1981-04-21
Abstract: PURPOSE: To remove harmful components and the soot and dust in waste gases by forming a moving bed part for a medium that adsorbs harmful components in waste gases such as sulfur oxide.  
     CONSTITUTION: When the waste gas discharged from a combustion device 1 arrives at an adsorbing and dust removing device 3 through a waste gas pipeline 2, a moving bed of a medium 8 is formed and harmful components in the waste gas, particularly, SOX are adsorbed by the same, and fly ashes and other dust are removed. Activated carbon is best suitable for the medium. The active sites on the surfaces of the activated carbon 8 are occupied gradually by SO 3  sulfuric anhydride and H 2 SO 4  sulfuric acid in an adsorbed state while it descends in the device 3, and at the point of the time when it is discharged to the outside of the device, it is nearly satd. The activated carbon that has adsorbed SOX is desorbed of H 2 SO 4  by a method such as washing, and is thereby regenerated. As a byproduct, H 2 SO 4  is recovered. The treated gas is sucked by a fan 4 under the flow rate controlling by a damper 6 and is released through a pipeline 5a out through a chimney 7 into the atmosphere.

Title: Water removal for aromatic compound nitration
Inventor: ROBAATO MATSUKOORU
IPC: C07C201/08
Filed: 1981-04-21
Abstract: Nitrobenzene and other aromatic nitro compounds can be obtained efficiently by the mixed acid nitration process by passing nitrogen or other gas inert to the nitration reaction through the reaction mass during reaction. The inert gas captures water, introduced for example with reaction feedstuffs, and so enables the sulfuric acid concentration to be maintained in an optimum range from 70-75% by weight to ensure sufficient generation of nitronium ions to act as nitrating agent.

Title: Manufacture of melamine
Inventor: RUUDORUFU BAN HAADOBERUDO
IPC: C07D251/60
Filed: 1980-05-02
Abstract: An improved method for the preparation of melamine by the conversion of urea and/or thermal decomposition products thereof. The urea and/or thermal decomposition products are converted to melamine in the presence of a gas mixture containing ammonia and carbon dioxide in a reaction zone containing a fluidized bed of catalytically active material. Melamine is desublimated from the melamine containing gas mixture in a desublimation zone by a dry-capture method leaving a desublimator off-gas mixture of ammonia, carbon dioxide and gaseous impurities. A major portion of this desublimator off-gas mixture is compressed and recirculated to the reaction zone as fluidizing gas for the bed of catalytically active material, without intervening treatment to remove gaseous impurities from the desublimator off-gas.

Title: Superconductive latching/sfq hybrid ram
Inventor: NAGASAWA SHUICHI
IPC: G11C11/44
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To substantially reduce a necessary AC bias current by using an effective combination of an AC type logical circuit biased by an AC current and a fluxoid type logic circuit biased by a DC current. SOLUTION: A 256 RAM block construction comprises a memory cell with 16 row and 16 columns, a voltage type logic driver circuit and sense circuit composed of superconductive latching elements biased by an AC current, and a fluxoid type logic decoder circuit composed of a superconductive single fluxoid quantum (FSQ) biased by a DC current. An AC power used for the whole RAMs can largely be reduced by arranging the decoder circuit part to be a fluxoid type logic circuit biased by a DC current, and an increase in AC power consumption in the driver circuit can be absorbed by adopting a multi-driver system.

Title: Back-space unit
Inventor: FURUTA KENJI
IPC: G11B15/20
Filed: 1979-05-15
Abstract: PURPOSE: To fix how much recording contents are automatically rewound, without reference to a tape drive speed, by changing a back-space time in proportion to the tape drive speed.  
     CONSTITUTION: When a tape deck is changed from a reproduction mode over to a stop mode and switch S 1  is turned OFF, multivibrator 30 is triggered and DC voltage signal E5 is supplied to motor 26 for a time corresponding to a fixed time constant, thereby performing the back-space operation of a tape around reel 24. Thus, the back-space time is in proportion to the time constant of multivibrator 30. This time constant is determined by the combination of capacity C3 and resistance 18 2  or 20 2  corresponding to a tape drive speed.

Title: Temperature controller
Inventor: YOSHIKAWA TOMIO
IPC: G05D23/24
Filed: 1981-04-22
Abstract: PURPOSE:To reduce the capacity of a power supply transformer and to realize the miniaturization of the said transformer, by avoiding the overlap of the ranges of temperature between the ON and OFF of a 2-step temperature controller and at the same time avoiding the simultaneous conduction of two auxiliary relays for an electric circuit. CONSTITUTION:Auxiliary relays 8 and 9 are actuated when the resistance value of a thermistor 1 changes with the temperature change, and at the same time an inverting action is carried out for a transistor TR4 by means of a TR22 and a resistance 21 which are provided at the output side of a comparator 2 of the 1st stage. The relay 8 is turned on at the 1st stage when the minus side voltage is higher than the plus side voltage with the comparator 2; and the relay 9 is  turned on at the 2nd stage when the plus side voltage is higher than the minus  side voltage with the comparator 3 respectively. As a result, the simultaneous  operation is avoided fo the auxiliary relays at the 1st and 2nd stages. Thus the  load of the circuit is reduced to realize the miniaturization of a power supply transformer.

Title: Paper conveyor
Inventor: NAO MANABU
IPC: G07G5/00
Filed: 1978-05-22
Abstract: PURPOSE: To prevent the malfunction of a paper conveyor by providing means for confirming the change-over of a gate, which is operative to perform the intake and return of bank notes in accordance with the inspected results at an inspecting unit so that the change-over malfunction may be detected.  
     CONSTITUTION: Detectors 51 to 53 are arranged midway of a paper conveyor passage. If bank notes inspected at an inspecting unit 2 are found false, the output of the detector 51 effects the change-over gate 30 together with NG signal outputs through an AND gate 54 to convey the bank notes to a return exit. When the bank notes passes through the detector 53, the signals indicative of the passage are fed together with the NG signals to an alarm detector 58 through an AND gate 55 and an OR gate 57. The detector 58 generates an alarm when the output of the gate 57 is zero. Both the OK signals indicative to the fact that the geniuneness of the bank notes in the unit 2 and the output of the detector 52 are fed to an alarm detector 58 through an ND gate 56 and the alarm detector 58. With the zero level of the output of the OR gate 57, the detector 58 judges that the bank notes conveyed through the gate 30 have been erroneously treated thereby to generate an alarm.
