Inventor: KUZUMI SHOSUKE
IPC: G06F12/08
Filed: 1993-11-30
Abstract: PURPOSE:To give flexibility to the unit by easily employing a write-back system. CONSTITUTION:If a cache miss is caused at the time of a write request from a computing element 1, only a memory 19 is written first by a non-write allocation system and the current block address is stored in a register 14. If a cache miss is caused at the time of next writing, a WA signal 11 from a control circuit 12 is turned ON on condition that a block address as an object of writing coincide with the block address of the register 14, and a block including data to be written by a write allocation system is posted to a cache memory 5 to rewrite data on the cache memory 5. when the block address as the object of writing does not match the block address in the register 14 in case of the cache miss at the time of the next writing, the data to be written by the non- write allocation system are rewritten directly on the memory 9.

Inventor: KATAYAMA JUNICHI
IPC: B21D15/04
Filed: 1987-12-23
Abstract: PURPOSE:To easily form rectilinear propagation waves on the outside or inside of a large diameter pipe without generating wrinkles and bends by changing the position of the internal surface and that of the external surface of a totally circular screw roll and an eccentric screw roll arranged on the internal and the external circumference of the pipe. CONSTITUTION:When rectilinear propagation waves are formed on the inside of a stock pipe 4, the totally circular screw roll 1 is positioned along the internal wall of the stock pipe 4 and a left-handed eccentric screw roll 8 is positioned on the external circumference. When an internal and an external rotor are rotated once in the same direction at the same time, the radius of the external eccentric screw roll 8 gradually contracts the internal wall of the pipe to the center. The pipe wall is bent by internal roll in the circumferential direction, rectilinear propagation waves gradually are formed and at the same time advanced by one pitch. When rectilinear waves are formed on the external side of the pipe, the eccentric screw roll 1' is laid along the internal circumferential side and the totally circular screw rolls 20, 20' and the left-handed screw roll are laid along the external side. In this way, a bellows flexible pipe having rectilinear propagation waves fitting into the purpose is obtained.
