    • In an inter-subsystem communication system which has a communication queue enqueued by one subsystem having processors and dequeued by another subsystem having processors, there is provided between the subsystems direct memory access means which permits either of the subsystems to directly access a memory of the other subsystem, and in a queue element enqueued by the one subsystem is inserted memory access control information necessary for accessing the one subsystem, whereby a high-grade function is performed by the plurality of subsystems. When the source subsystem issues an enqueue command, the queue element length of a queue element produced in response to the queue command is compared with a remaining space of the queue and, if the comparison result satisfies a predetermined condition, an overflow interruption is caused in the processor of the source subsystem, thereby to efficiently detect a queue overflow state or queue usable state.
    • 在子系统通信系统中,具有由具有处理器的一个子系统排队的通信队列并由具有处理器的另一个子系统排队的子系统间通信系统,在子系统之间提供直接存储器访问装置,其允许子系统之一直接访问另一个的存储器 子系统,并且在由一个子系统排队的队列元素中插入访问一个子系统所需的存储器访问控制信息,由此由多个子系统执行高级功能。 当源子系统发出入队命令时,将与队列命令对应的队列元素的队列元素长度与队列的剩余空间进行比较,如果比较结果满足预定条件,则会导致溢出中断 源子系统的处理器,从而有效地检测队列溢出状态或队列可用状态。

    • A tetraalkylthiuram disulfide is prepared in a higher yield without formation of by-products by subjecting the corresponding alkali metal dialkyldithiocarbamate to electrolytic oxidation, which is carried out in a two-layer electrolytic solution consisting essentially of either (1) water and carbon disulfide or (2) water and a mixture of carbon disulfide and a halogenated alkane of higher density than water, the carbon disulfide being predominant in the mixture, by means of electrodes placed in the aqueous layer containing the dialkyldithiocarbamate. The resulting disulfide is extracted to the lower layer of the electrolytic solution and is recovered from the layer. The dialkyldithiodicarbamate can be continuously produced in situ by adding carbon disulfide and dialkylamine gradually to the aqueous layer of the electrolytic solution, which contains an alkalimetal hydroxide produced during the electrolytic oxidation of the dialkyldithiocarbamate.
    • 通过使相应的二烷基二硫代氨基甲酸碱金属二烷基二硫代氨基甲酸盐进行电解氧化,可以以较高的产率制备四烷基秋兰姆二硫化物而不形成副产物,该电解氧化基本上由(1)水和二硫化碳组成的双层电解质溶液或( 2)水和二硫化碳与卤化烷烃的混合物比水密度高,二硫化碳在混合物中占优势,借助放置在含二烷基二硫代氨基甲酸二烷基酯的水层中的电极。 将得到的二硫化物萃取到电解液的下层,并从层中回收。 二烷基二硫代氨基甲酸二烷基酯可以通过在二烷基二硫代氨基甲酸酯的电解氧化中产生的含有碱金属氢氧化物的电解液的水层中逐渐加入二硫化碳和二烷基胺而原位连续生产。
