Title: Decontamination of zirkaloy through slug by low-temperature crucible fusing work accompanied by continuous drawing of ingot
Inventor: RUNE PISHINATO
IPC: G21F9/28
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To remove contamination of alloy by melting a zircaloy based alloy and transferring a radioactive substance into a stag containing cryolite having a specific structure. SOLUTION: An alloy containing zircaloy is melted and mixed with a slag containing cryolite comprising 3MF-AIF3 (M: alkali metal K, Na, Li). The slag may be a mixture of these cryolites. During fusion of the alloy, radioactive elements migrate into the slag and captured thereat. Zircaloy can be provided more easily with reductionability and solution capability for radioactive nuclide by selecting the cryolite. Since ammonium does not migrate from the slag to the zirconium, the slag is stabilized.

IPC: H04B1/74
Filed: 1982-02-04
Abstract: PURPOSE:To reduce the facility cost of the whole system, by providing a maintenance panel in common between two transmitters, and selecting one transmitter through a changeover switch. CONSTITUTION:While a changeover switch SW in the maintenance panel 12C makes a connection between terminals (a) and (c), a transistor TR1 turns on in response to (high)-level data inputted through the data bus 15A of a data tansmitter 11A, so a current flows in the order of +VC1, 15, TR1, and COM1 to turn on a light emitting element 15. At this time, the terminals (b) and (c) of the SW are disconnected from each other, so the data is inputted to a data bus 15B as well as the data bus 15A, but a transistor TR2 is turned off. Therefore, the power source +VC2 and COM2 of a transmitter 11B are turned off. When the switch SW is switched to connect the terminals (b) and (c), on the other hand, exactly the opposite state to said state is obtained and the light emitting element 15 is powered up by the power source in the transmitter 11B.

Filed: 1987-01-28
Abstract: PURPOSE:To shorten the program executing time in a computer system by carrying out the scheduling process of an instruction after regarding a group of instruction contained in an effect range as an instruction based on the information added to a subject code. CONSTITUTION:A syntax structure analyzing part 21 of a compiler 2 read a source program 1 and produces an intermediate text 24. A code generating part 22 reads the text 24 and produces an object code 25 added with the information on an effective range of the local branches. An instruction scheduling part 23 reads said code 25 and performs a scheduling process of an instruction after defining a group of instructions kept in said effective range as an instruction and rearranges the instruction for production of an object code 3. Thus the instructions are rearranged so that the conflicts of registers are decreased and the fixed waiting time is reduced. Therefore the program executing time is shortened in a computer system where instructions are carried out by a pipeline system.
