    • A cement admixture for concrete using a polycarboxylate based water reducing agent that can produce light concrete with little slump loss and good workability that prevents dragging and the like and having no material separation, and a cement composition using the cement admixture are provided.A cement admixture for concrete using a polycarboxylate based water reducing agent, comprising bentonites (one or more selected from a group comprising bentonite, acidic white clay and active white clay are preferable) and polyvinyl alcohol, or the cement admixture further compounding saccharides. A cement composition, wherein cement, a polycarboxylate based water reducing agent, bentonites and polyvinyl alcohol are main components, or the cement composition, further compounding saccharides. Preferably, the cement composition, wherein the polycarboxylate based water reducing agent is 0.3 to 5 parts based on 100 parts of cement, bentonites are 0.1 to 10 parts, polyvinyl alcohol is 0.03 to 1 part and saccharides are 0.01 to 0.2 part.
    • 本发明提供一种混凝土用水泥混合物,该混凝土采用聚羧酸酯类减水剂,能够制造出具有很小坍落度损失的轻质混凝土和良好的加工性能,能够防止拖曳等并且不进行材料分离,并且提供了使用该水泥混合物的水泥组合物。 包含膨润土(选自膨润土,酸性白粘土和活性白土中的一种以上的一种或多种)的聚碳酸酯类减水剂的水泥混合物,优选聚乙烯醇,或水泥混合物进一步混合糖类。 水泥组合物,其中水泥,聚羧酸盐类减水剂,膨润土和聚乙烯醇是主要成分,或水泥组合物,进一步配混糖。 优选地,其中聚羧酸酯类减水剂为基于100份水泥为0.3〜5份的粘土组合物为0.1〜10份,聚乙烯醇为0.03〜1份,糖类为0.01〜0.2份。

    • The memory access device includes: a plurality of command division sections provided for a plurality of masters; a plurality of inter-master arbitration sections provided for a plurality of banks; and a memory control section. Each of the command division sections divides a command issued by the corresponding master into a plurality of micro-commands when the access region of the command is over two or more banks among the plurality of banks, each of the micro-commands being a command accessing only one of the two or more banks, and gives each of the micro-commands to an inter-master arbitration section corresponding to the bank including the access region of the micro-command. Each of the inter-master arbitration sections arbitrates micro-commands given from the command division sections to select one. The memory control section selects one of a plurality of micro-commands selected by the inter-master arbitration sections to perform memory access.
    • 存储器访问装置包括:为多个主器件提供的多个命令分割部分; 为多个银行提供的多个主控间仲裁部分; 和存储器控制部分。 当命令的访问区域在多个存储体中的两个或更多个存储体上时,每个命令分割部分将由相应主机发出的命令分成多个微命令,每个微命令是命令访问 仅将两个或更多个存储体中的一个存储,并且将每个微指令分配给与包括微指令的存取区域的存储体对应的主站间仲裁部分。 每个主控间仲裁部分仲裁从命令分割部分给出的微指令以选择一个。 存储器控制部分选择由主机间仲裁部分选择的多个微指令之一来执行存储器访问。
