Title: Evaporation processing of radioactive waste liquid
Inventor: KAWAMURA FUMIO
IPC: G21F9/08
Filed: 1993-07-28
Abstract: PURPOSE:To reduce the quantities of volatilized ruthenium and technetium in a process of collecting a nitric acid solution by a method wherein waste liquid to be reprocessed is jetted in the shape of a droplet onto a heating surface, while a centrifugal force is given to the waste liquid in a rotary tower, and the waste liquid in the vicinity of the central part of the axis of rotation is evaporated by heating. CONSTITUTION:An evaporating device is constructed of an evaporating vessel 1 equipped with a heater 3, a heating surface 6 in the evaporating vessel 1 and a rotary drum 4 jetting supply waste liquid F to be reprocessed onto the heating surface 6, and heating steam H is supplied to the heater 3 from a steam generating device 2. The supply waste liquid F to be reprocessed is jetted in the shape of a droplet from the rotary drum 4 and evaporated in a moment on the heating surface 6 kept at a high temperature by the heating steam H. Concentrated waste liquid C goes down along the heating surface 6 and is collected in a concentrated waste liquid storage tank 5. According to this method, the quantity of volatilized ruthenium can be reduced sharply, since a nitric acid is evaporated in a moment from the waste liquid F of low nitric acid concentration, shifted to a vapor phase R and collected. Besides, volatilization of technetium can be suppressed as well, since the evaporation processing is performed in a moment in a state of the concentration of the technetium being low.

Abstract: PURPOSE:To minimize decrease of a punch through voltage and to decrease a distance between capacitors by forming trenches for providing trench-type capacitors, and implanting boron ions into the inner walls of the trenches and into the surface of the substrate simultaneously and driving in the implanted boron ions to provide a P-type well. CONSTITUTION:Trenches 22 are provided in a silicon substrate 1 and a thin silicon dioxide film 21 is formed on the surface. The silicon substrate except its region where a P-type well is to be formed is masked with a photoresist so that boron ions for example are implanted. The implantation of boron ions is performed obliquely at a certain angle with respect to the principal surface of the silicon substrate. The implanted boron ions are driven in to provide a P-type well 23. After an element isolating region 2 is formed, a photoresist mask 161 is provided so that arsenic ions having the conductivity type opposite to that of the substrate 1 are implanted obliquely to form an N<+>-type layer 4. Then, after a capacitor insulating film 5 and an N-type polycrystalline silicon film 6 are deposited sequentially on the inner walls of the trenches 3, the trenches are filled with a second polycrystalline silicon film such that the surface is flattened. The N-type polycrystalline silicon film 6 is selectively removed and a capacitor electrode pattern is formed.

IPC: F23N5/02
Filed: 1982-10-22
Abstract: PURPOSE:To make it possible to perform an ignition operation accurately by a method wherein the ratio of a fuel to air is increased only when the ambient temperature at the time of ignition is low and the temperature of a water heater is low. CONSTITUTION:When the pre-purging of a combustion chamber 5 is completed and the sparking condition of an ignition plug 7 with respect to combustion air is set, a pre- purge timer contact 21 is closed. As a result, an oil pressure pump 4 is energized to operate and a control valve 3 is energized to open. In this case, if the temperature detected by a thermosensor TH is lower than -5 deg.C, an output switch 22 is opened and a control valve 17 is kept closed without being energized. At the same time, a fuel oil in a fuel oil supply pipe 2 is pressurized to the maximum pressure of the oil pressure pump 4 and is sprayed from a spray nozzle 1 so that the ignition operation is performed accurately. When the combustion of the fuel oil is stabilized, the temperature detected by the thermosensor TH becomes higher than 0 deg.C and the output switch 22 is closed. Consequently, the control valve 17 is energized to open and the discharge side and the sucking side of the oil pressure pump 4 are made to communicate with each other through a bypass pipe 19 so that pressure of the pump 4 is reduced to a predetermined value by the operation of an oil pressure adjust valve 18 to thereby obtain an optimum air-fuel ratio.
