  • Patent number: 9688000
    Abstract: The present invention provides a producing method of concrete capable of appropriately controlling setting and hardening, and having excellent flexibility of production and handling of concrete. The producing method of concrete includes a cement paste mixing step and a concrete mixing step. In the cement paste mixing step, cement, mixing water and retarder are mixed together to obtain cement paste. According to this, setting and hardening of the cement paste are suppressed, and it is possible to store the cement paste for predetermined time. In the concrete mixing step, aggregate is input into the cement paste, and they are mixed together to obtain concrete. By the mixing operation, a setting-delaying effect is canceled.

  • Patent number: 8006030
    Abstract: Data is written in data areas (202) and information for correcting an error of the data and status information indicating that the data has been written are written in redundant areas (203) sequentially from the first page of a physical block (201). In the step of creating information to be written in the physical block (201), the redundant areas (203) of the pages are subjected to a binary search to temporarily identify a last valid page. Further, the contents of every area (the data areas and the redundant areas) of the temporarily identified last valid page and a page adjacent to the temporarily identified last valid page are checked to finally identify the last valid page and make a judgment as to whether or not an error page resulting from power-down exists.

  • Patent number: 7436898
    Abstract: An integrated circuit (IC) card capable of a high-speed data transmission to/from a data transmission apparatus having low processing capability. A controlling section generates a data packet by adding management information including information regarding a data length of the data packet, and divides the data packet to generate data blocks. The data length of the data block is designated from the data transmission apparatus. When the data blocks which compose the single data packet are sent to the transmission apparatus a communicating section sends an interrupt signal to the data transmission apparatus if the data block including the management information is to be sent, and does not send the interrupt signal to the data transmission apparatus if a data block not including the management information is to be sent.
