Title: Spent nuclear fuel dissolving solution by method for supercritical carbon dioxide extraction and method for denitrifying high level radioactive waste liquid
Inventor: ISO SHUICHI
IPC: G21F9/06
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to simplify a denitrifying method by the reduction in nitric acid concentration of high level radioactive waste liquid by heating and pressurizing liquefied carbon dioxide mixed with tributyl phosphate(TBP) to specific temperature and pressure to supercritical fluid, and denitrifying the spent nuclear fuel dissolved solution during the reprocessing step. SOLUTION: Liquefied carbon dioxide mixed with tributyl phosphate(TBP) is heated and pressurized to 60 to 80 deg.C and 10 to 26Mpa to supercritical liquid, supercritical carbon dioxide fluid fed via the solution collected in an extraction vessel 1 is returned to the normal pressure at the pressure via a restrictor 8, and then introduced to a capturing vessel 10. After metal element such as uranium separated at the initial stage of the extraction is recovered into the vessel 10, then further supercritical carbon dioxide fluid is continuously fed, nitric acid in the sample solution is extracted, and recovered to another capturing vessel. The extracting operation is conducted for a predetermined time to denitrify the nitric acid solution.

Inventor: INUZUKA HIDEO
IPC: G11B7/09
Filed: 1994-03-22
Abstract: PURPOSE:To exactly detect the position of an objective lens by making a part of a transmitted light beam from a light emitting element incident on the light receiving surface of a light receiving element by changing the direction to the light receiving element by means of a light transmitting member and receiving only a luminous flux to be made incident. CONSTITUTION:A light emitting element 22 is fixed on a first piece 20a so that its transmitting optical axis becomes perpendicular to the tracking (Tr) and the focusing (Fo) directions. A light receiving element 23 is fixed on a fourth piece 20d so that its light receiving surface becomes perpendicular to the Fo direction and is made to be opposite, back to back, to a light converging part on an optical recording medium by means of an objective lens 6. A reflection plate 27 changing the direction of the transmitting light beam from the element 22 toward the element 23 and a light shielding plate 14 having a slit hole 14a, through which a part of the reflected beam of the plate 27 is made to transmit on the surface in the Fo direction, are fixed on the side surface of a movable body 7. The widths of the hole 14a in the Fo and the Tr directions and passing luminous flux are adjusted and equal light quantities are made incident on the light receiving surfaces 23a, 23b sectioned in the Tr direction when the movable body 7 is on the neutral position. Consequently, only a luminous flux to be made incident is received and the position of the lens 6 is correctly detected.

Title: Back boost type converter circuit
Inventor: OTA TOSHIYUKI
IPC: H02M3/155
Filed: 1990-03-23
Abstract: PURPOSE:To reduce power loss by making the primary coil of a transformer act as a reactor, and also controlling the ON.OFF of an FET by a secondary coil. CONSTITUTION:The energy, which is accumulated in the primary coil of a transformer 3 when an FET 1 has become ON, is released from the primary coil of the transformer 3 to a G line when the FET 1 has become OFF. At this time, a current flows from the source terminal side to the drain terminal side through the body diode built in an FET 2. Moreover, the voltage at A point of the secondary coil of the transformer 3 becomes positive, so the voltage of the gate voltage of the FET 2 also becomes positive, and by this gate voltage the FET 2 becomes ON. The body diode is at high impedance, so the current flowing in the FET 2 flows through the low impedance between the source terminal and the drain terminal. The resistance between the drain and the source when this FET 2 is ON is small, so the power loss during the ON period of the FET 2 also becomes small.
