  • Patent number: 9060538
    Abstract: The present invention provides soy sauce that comprises significant amounts of peptides, and, in particular, hypotensive peptide Gly-Tyr and hypotensive peptide Ser-Tyr, exhibiting a high degree of angiotensin-I-converting enzyme-inhibitory activity and has hypotensive effects while containing no hypotensive agent. Target soy sauce is obtained by mixing soy sauce koji having protease activity of 20 to 300 U/g koji with an aqueous common salt solution and subjecting the mixture to heated digestion, followed by compression filtration. Target soy sauce with a good flavor is obtained by adding soy sauce lactic acid bacteria and soy sauce yeast cells to the moromi mash after heated digestion, and subjecting the resultant to fermentation and maturation, followed by compression filtration.

  • Patent number: 6505265
    Abstract: A bus arbitration system uses different arbitration rules at different times, by periodically changing the priority order of the bus masters; by masking further bus requests from a particular bus master for a certain interval each time that bus master is granted the use of the bus; by masking requests from bus masters other than a central processing unit for certain intervals while the central processing unit is processing an interrupt; by raising the priority of a particular bus master if a bus request from that bus master remains unacknowledged for a certain interval; or by ignoring bus requests from the central processing unit while another bus master is performing a certain process.

  • Patent number: 6088272
    Abstract: A memory system includes a plurality of output buffers each of which outputs one of a plurality of one-bit signals forming data. The output buffers are put into a plurality of buffer groups. The memory system further includes a controller for feeding timing signals to the corresponding buffer groups via delay circuits having mutually different time constants, respectively. The timing signals include certain timing which causes the output buffers to output the corresponding one-bit signals. Since the foregoing certain timing is delayed depending on the time constants of the delay circuits, although the output buffers in the same buffer group output the corresponding one-bit signals simultaneously, the output buffers in the different buffer groups output the corresponding one-bit signals with mutually different timing.

  • Patent number: 5983289
    Abstract: A data transfer controller transfers data in blocks having a restricted set of permitted sizes. Before transferring each block, the data transfer controller performs a segmented comparison on the current data address, at which the block starts, and a stopping address, at which the entire data transfer will end, and determines the block size from the result of the segmented comparison. In the segmented comparison, the data transfer controller compares a first part of the data address with a first part of the stopping address, then compares a second part of the data address with a second part of the stopping address. The comparison of second parts is made in different ways, depending on the result of the comparison of first parts.
