  • Publication number: 20080085227
    Abstract: The microreactor for mixing and discharging multiple raw material liquids is obtained by laminating: a base plate in which a raw material introducing fluid channel is formed; a raw material introducing plate; and a mixing fluid channel plate which is arranged between the base plate and the raw material introducing plate, and in which a mixing fluid channel is formed. The microreactor includes: a mixing fluid channel in the mixing fluid channel plate which is formed in the mixing fluid channel plate, and in which a flow is contracted in its width direction; and a mixing fluid channel in the base plate which is formed in the base plate, and which has a fluid channel cross-section which becomes larger in its depth direction as it goes downstream. The mixing fluid channel in the base plate communicates with the mixing fluid channel in the mixing fluid channel plate, and is connected to an outlet orifice from which to discharge the mixed liquids.

  • Publication number: 20080046611
    Abstract: An arbiter circuit includes a priority coefficient calculating unit, a priority coefficient comparator an acceptance determining unit, and a priority determining unit. The priority coefficient calculating unit calculates for each request an arbitration priority coefficient based on a priority level set for each request by requesters. The priority coefficient comparator compares arbitration priority coefficients calculated for the requesters by the priority coefficient calculating unit. The acceptance determining unit determines whether to accept the requests based on the comparison result by the priority coefficient comparator. When the arbitration priority coefficient calculated by the priority coefficient calculating unit is equal between two or more requests, the priority determining unit determines a priority order for accepting the requests.

  • Patent number: 7076754
    Abstract: A functional block design method capable of shortening the period needed for developing functional blocks in compliance with orders. A logic design is prepared for a desired number of memory floor plan blocks with respective predetermined data storage capacities and a fixed block different from the memory floor plan blocks, and block-based design data is created in compliance with the logic design. The created block-based design data is verified in that a constraint on the creation of a CPU macro is always fulfilled within the limits up to which the memory blocks can be mounted. Using the verified block-based design data, design data of a CPU macro functional block in which a desired number of memory blocks corresponding to a desired memory capacity are connected to the fixed block is generated.

  • Patent number: 6799310
    Abstract: An integrated circuit layout method for placing a plurality of cells within a chip comprises a process for sorting the plurality of cells (or function macros) that are to be laid out in order of their delay times (or operation speed margins for macro), placing cells (or macros) having the largest delay times (or smallest speed margin for macro) closer to the peripheral area of the chip, and as the cell delay times get smaller(or the speed margins get larger), placing the relevant cells (or macros) closer to the central area of the chip.
