Title: Parallel processing computer with alterable preference of memory access
Inventor: MAIKERU ERU JIIGURAA
IPC: G06F12/08
Filed: 1988-07-29
Abstract: PURPOSE: To improve the performance in a state wherein a lock step is not attained without substantially spoiling the performance when the lock step is obtained by providing a priority changing means which periodically alternates fixed priority levels. CONSTITUTION: Eight high-speed processors, i.e., computing elements(CE) 10 are connected to two central processing cache boards 12 by a switch 14 positioned on the back surface where the CEs 10 and cache boards are inserted. Then a storage element is interleaved and fixed priority levels are assigned to the processors, but when no lock step is present, the fixed priority levels are rotated periodically among the processors. Cycles between rotations of the priority levels are made long enough not to hinder the lock step from being secured, but preferably not made too long to excessively reduce advantages of common use of delay of rotations of the priority levels. Consequently, there is no large loss of the speed in case of the lock step and the processing speed not in the lock step state can be improved.

Title: Vibration reducing method and vibration reducing active control device
Inventor: SE MEISHO
IPC: E04H9/02
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing vibration transmitted to a structure from outside and a vibration reducing active control device. SOLUTION: A fixed connecting method is adopted in one end of a stiffener and a main structure, another one end is connected to the main structure through a control device. When mounting, a squared housing 1 of a connector is fixed onto the main structure, simultaneously with fixing the stiffener onto a round hole in both ends of a movable slide bar 2 by a U-shaped member. When the movable slide bar 2 is incapable of freely making a motion, relative displacement must not be changed between the main structure and the stiffener, thus, deformation of the stiffener is changed in accordance with deformation of the main structure. In the case that the movable slide bar is desired to be captured by the housing of the connector, by brake round bars 3, 4, 5, 6, desired operation can be attained by a slope principle.  In this way, a very good energy consumption effect can be acquired, accordingly, requirement for reducing vibration can be solved.
