Title: Method of recovering uranium and transuranic elements from spent nuclear fuel
Inventor: TODOKORO AKIO
IPC: C25B1/00
Filed: 1998-03-30
Abstract: In this method the steps for recovering uranium and transuranic elements are simplified, and the generation of waste solvent and waste materials is suppressed. Spent nuclear fuel is dissolved in nitric acid (S100) and the resulting solution is subjected to electrolytic oxidation so that U, Np, Pu, Am is oxidized to VI using Ce as oxidation catalyst. The solution is cooled, and nitrates of valence VI thereby deposit as crystals and are separated from the mother liquor (S104). The mother liquor is heated and concentrated (S114). The mixed crystalline deposit is dissolved in nitric acid (S106), uranyl nitrate is deposited alone by cooling (S108), and the crystals are separated from the U, Np, Pu, Am mixed solution (S110). The uranyl nitrate is dissolved in nitric acid (S112), and the heated and concentrated mother liquor is added to it to prepare another mixed solution. This mixed solution is then subjected to electrolytic oxidation to oxidize the remaining U, Np, Pu, Am to valence VI, and the solution is cooled so that U, Np, Pu, Am are coprecipitated with uranyl nitrate as crystals, and can be separated from high level radioactive effluent (S118).

Title: Axially adjustable steering column assembly
Inventor: BARTON LAURENCE GEORGE HERBERT
IPC: B62D1/185
Filed: 1998-09-23
Abstract: A bush 3, eg of moulded plastics, is slidably mounted with an interference fit on the inner column member which may be a triangular section tube 2. The tube 2 with the bush 3 is then inserted in the outer tube 1 until the bush 3 lies wholly within the outer tube 1. Adhesive is then injected through holes 4 in the wall of the outer tube 1 to secure the bush 3 to the outer tube 1. Thus the inner tube 2 can slide freely within the bush 3 with the comparatively thin wall of the bush 3 taking the shape of the inner tube 2. The bore of the outer tube 1 does not need to be machined to have a close tolerance with the bush 3.

Patent JP-H07221630-A (JP)
Title: Switching circuit and interface circuit
Inventor: MAEDA AKIRA
IPC: H03K17/04
Filed: 1994-01-31
Abstract: PURPOSE:To perform switching at a high speed by connecting a resistor to the emitter of a transistor and setting current feedback so as to prevent more than required base current from flowing. CONSTITUTION:When pulses for turning a GND1 to an L level are impressed to the base B1 of the transistor TR1, the base current IB1 flows in the H level of the pulses, the transistor TR1 is turned to an ON state and a collector current IC1 which is the multiple of the current amplification factor hfe1 of the base current IB1 flows. Then, by making the collector current IC1 flow in the resistor R2, the output voltage of IC1XR2 is generated at both ends of the resistor R2. In the meantime, an emitter current IE1 (that is IB1+IC1) flows to the resistor R1 on the side of the emitter E1. Thus, the voltage IE1XR1 by a voltage drop is generated at both ends of the resistor R1, the voltage between the base B1 and the emitter E1 drops and the base current IBI is reduced as well. That is, when the base current IB1 is increased and the emitter current IE1 is increased, the current feedback is set so as to lower the base current IB1.

Title: Drain pan and its manufacturing method
Inventor: HAYASHI NAOTO
IPC: F24F13/22
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To maintain at least a certain antibacterial effect for a specific amount of time and to easily change the continuation period of the antibacterial effect by performing the injection molding of a mixture containing soluble glass carrying an inorganic antibacterial agent and resin. SOLUTION: A drain pan contains soluble glass 2 carrying an inorganic antibacterial agent 1 and resin. A metal ion such as silver and copper is the main inorganic antibacterial agent 1 that is carried by the soluble glass 2. When silver is used as the antibacterial agent, a silver ion elutes by dissolving carrier structure that is made of the soluble glass 2. The eluted silver ion indicates an antibacterial operation. The drain pan is manufactured by performing the injection molding of the mixture of the inorganic antibacterial agent 1 being carried by the soluble glass 2 and the resin. Then, antibacterial force can be changed according to the amount of addition of the inorganic antibacterial agent, while continuation time can be adjusted by changing the molecular weight of the soluble glass 2.
