    • In order to provide a pipe joint of stainless steel including more than 10% of Cr which joint has excellent shape memory effect, the stainless steel comprises up to 0.10% of C, 3.0 to 6.0% of Si, 6.0 to 25.0% of Mn, up to 7.0% of Ni, more than 10.0 to 17.0% of Cr, 0.02 to 0.30% of N, 2.0 to 10.0% of Co, and optionally one or more selected from 0.05 to 0.8% of Nb, 0.05 to 0.8% of V, 0.05 to 0.8% of Zr, 0.05 to 0.8% of Ti, up to 2.0% of Mo and up to 2.0% of Cu and the alloying components are balanced so that no .delta.-ferritic phase may substantially appear in the annealed condition. Since the joint is treated so that it has such a shape memory effect that it will recover the memorized original shape with a smaller diameter when heated to an appropriate temperature, it can fasten a pipe or pipes merely by heating. Furthermore, the joint is galvanized on its surface so as to improve sealability in fastening the pipe(s) and to suppress crevice corrosion from occurring at the interface between the joint and pipe(s).

    • Preload register groups are respectively provided for the plurality of scalar processors which execute iterative processing in distributed manner. Each group consists of preload registers corresponding to a plurality of data arrays that appear in the iterative processing. According to address information about the plurality of arrays to be preloaded specified by any of the processors, a preload control unit reads partial data groups of one of the arrays to be first processed by all of the processors from the main storage in parallel. Then, the same operation is performed on another array. Subsequently, in the above-mentioned manner, remaining elements of the arrays are read from one array to another. A partial element group thus read sequentially is stored in the plurality of preload register groups in distributed manner. According to a load request issued from each processor, the array elements preloaded in the preload register groups corresponding to that processor are read in the order the array elements were preloaded.
    • 分别为分散执行迭代处理的多个标量处理器提供预加载寄存器组。 每个组由对应于迭代处理中出现的多个数据阵列的预加载寄存器组成。 根据关于由任何处理器指定的预先加载的多个阵列的地址信息,预加载控制单元并行地从主存储器读取所有处理器首先处理的阵列之一的部分数据组。 然后,对另一个阵列执行相同的操作。 随后,以上述方式,阵列的剩余元件从一个阵列读取到另一个阵列。 这样按顺序读取的部分元素组以分布的方式存储在多个预加载寄存器组中。 根据从每个处理器发出的加载请求,预先加载到与该处理器对应的预加载寄存器组中的阵列元素按照阵列元素被预加载的顺序被读取。
