Title: Stripping method of spent metallic fuel
Inventor: TOKIWAI MORIYASU
IPC: G21C19/38
Filed: 1989-08-17
Abstract: PURPOSE:To improve the dissolution treatment rate by repeating hydrogenation and dehydrogenation processes and producing powder or porous metal fuel prior to a dissolution process of spent metallic fuel and, at the same time, crushing a coated tube and increasing the contacting area with a molten metal. CONSTITUTION:Spent fuel 1 is transferred into a stripping tank 2 while being mounted on a carrier cart 3 having a pan, for instance, and then a gate 8 is closed and the tank is evacuated, thereafter a valve 7 is opened and a hydrogen gas is fed to the tank 2 through a hydrogen feeder 4, and finally hydrogenation and dehydrogenation of the fuel 1 are repeated. The feeder 4 can freely regulate the pressure of hydrogen to be fed, by means of a hydrogen adsorption metal 5 such as titanium and through temperature control of a heater 6. Temperature of the tank 2 and the feeder 4 are controlled independently, and hydrogenation and dehydrogenation are repeated by bringing the hydrogen partial pressure of the fuel 1 higher lower than that of the metal 5 until the fuel 1 becomes brittle, and therewith the fuel 1 swells and turns into a pulverized or a porous fuel 10, and a coated tube 9 is crushed down. By this procedure, the surface area of the fuel 10 contacting with a molten metal increases, and therefore the dissolution treatment rate also increases.

IPC: H02M7/10
Filed: 1985-09-26
Abstract: PURPOSE:To prevent the temperature variation of rectifying characteristic by providing a compensating diode which feeds a bias current having the same value as a rectifying diode, and canceling the temperature variation of a voltage across the rectifying diode by that of the voltage across the compensating diode. CONSTITUTION:A bias current I1 is fed among a resistor 8, rectifying diodes 3, 4, a resistor 9 and a ground. A bias current I2 is also fed among the resistor 8, compensating diodes 10, 11, a resistor 12 and the ground. When a peak value from an input signal line 1 is V0, voltage across the diodes 3, 4 is VD, voltage across the diodes 10, 11 is VD' and the potential of a connecting point C is used as a reference, potentials of terminals A, B become 2V0-2VD and 2VD'. Accordingly, the voltage V between the terminals A and B becomes as represented by the equation. When the characteristics of the diodes 3, 4 and 10, 11 are equalized and the resistor 12 is regulated so that current I1=I2 is satisfied, VDapprox.=VD' and Vapprox.=2V0 are obtained. Thus, it can prevent the variation due to the temperature change of the voltage V.

Title: Voltage adder circuit
Inventor: NAKAYAMA KAZUAKI
IPC: H03F1/32
Filed: 1982-12-03
Abstract: PURPOSE:To ensure the function as an adder even to a balanced input floated from paired earths by combining a voltage generator and a differential amplifier and adding the output of the differential amplifier in series to the voltage generator. CONSTITUTION:Transistors TRQ1a and Q1b are equal to voltage generators, and TRQ2a, Q2b, Q3a and Q3b are differential amplifiers respectively. An AC addition output voltage V0 sets the transmission conductances of the TRQ2a, Q2b, Q3a and Q3b at gm2 and gm3 respectively. Thus V0=Vi1+R(gm2Vi2+gm3Vi3) is satisfied, where R means resistance. That is, the adder adds balanced inputs Vi2 and Vi3 (Floated from earth) in series to the unbalanced input Vi1 (earthed at one side) with multiplication of gain. Furthermore the output currents of TRQ2a, Q2b, Q3a and Q3b generated from Vi2 and Vi3 are equal to differential currents and give no effect to the Vi1 at all.
