Title: Treatment of high level radioactive wastes
Inventor: HORIE MIZUAKI
IPC: G21F9/32
Filed: 1990-03-15
Abstract: PURPOSE:To collect elements of the platinum group easily without large amount generation of the secondary wastes and to reduce the volume substantially by adding an appropriate amount of a boron or boron compounds during heating-up and melting treatment of a calcined body of high level radioactive wastes. CONSTITUTION:A calcined body of high level radioactive wastes is added by a boron or boron compounds by 0.5 to 10% in a weight percent of the simple substance of boron and is treated by heating-up and melting in a reducing atmosphere at higher temperature than 1,000 deg.C, and therewith elements of the platinum group and the boron which exist in the calcined body, are alloyed. Alloy layers of the elements of platinum group obtained by this process are collected from oxides layers by sedimentation separation and residual oxides are solidified. A sodium borohydride, a boron nitride and so on are probable boron compounds which can be added to the calcined body and, among those, the boron nitride is the best one, in particular. With these procedures, simplification of treatment process and down-sizing of treatment device can be successfully intended. Moreover, volume-reduced solidification down to around a several tenth part, in comparison with a vitrification treatment, can be actually materialized.

Title: Central processor
Inventor: OTAKA MASAYUKI
IPC: G06F12/08
Filed: 1992-03-24
Abstract: PURPOSE:To improve the hit rate of a write-back system cache memory by applying it to a stack area. CONSTITUTION:When an arithmetic part 2 executes a program which performs memory arrangement for allocating a work area to the stack, an area after stack degeneration is not accessed again for the stack degeneration. A stack pointer change detection part 4 detects the value of a stack pointer only at the time of the stack degeneration so as to make the area ineffective on a cache memory 7, and reports the stack pointer value to a block invalidation control part 8 through an ineffective block information bus 6. The block invalidation control part 8 turns off the effective flag 11 of a block including a main memory block address 9 including a block address indicated with the stack painter value. Consequently, the area at the time of the stack degeneration can be made ineffective on the cache memory.
