摘要:
In a shared memory multiprocessor system, data reading accesses and data write-back completion notifications are selected in synchronism with all of the nodes to order them. In each of the nodes, a subject address of ordered data reading access is compared with a subject address of ordered data write-back completion notification to detect a data reading operation of the same address which is passed by the completion of the data writing-back operation. Both a data reading sequence and a data writing-back sequence are determined. At this time, such a coherency response for prompting a re-reading operation of the data is transmitted to the node which transmitted the data reading access, so that coherency of the data is maintained.

A shock absorption in a seat back of a seat, which is arranged in a bracket fixed on the seat back frame in the seat back and an operation lever attached to the bracket. In this arrangement, the bracket is formed such that upper and lateral wall regions are defined independently of each other, with a slit defined therebetween. The lower securing portion of the bracket, fixedly secured on the seat back frame, is relatively easy to bend forwardly relative to the seat back frame by an external load applied to the rearward side thereof. A stopper wire member, which has an abutment end portion, is provided over the vertical wall region of bracket and a part of the seat back frame, such that the abutment end portion is oriented toward the operation lever. Hence, the bracket is bendable forwardly by a great external load applied from the rear side of seat back frame, in which case, the operation lever in the bracket will be abutted against the abutment end portion of stopper wire member, causing both bracket and stopper wire member to bend forwardly, to thereby absorb a corresponding great shock.
