    摘要： In designing an integrated circuit, the size of a transistor is optimized together with the folding number thereof. The optimization of the size and folding number of the transistor is accomplished by using a folding model in which a plurality of folding numbers are assumed for one transistor size. In the folding model, if the lower limit value of the transistor size W is W0 and the height of a placement region for the transistor is H0, the folding number N can be determined arbitrarily so long as W/H0≦N≦W/W0 is satisfied. If the size of the transistor is optimized together with the folding number thereof by using the folding model so long as a given design constraint is satisfied, there can be designed an integrated circuit which has been improved in terms of area and performance.

    摘要： A gas-permeable material with excellent compatibility with blood comprising polyurethane, polyurethaneurea, or the derivatives thereof is provided. The polyurethane or polyurethaneurea is obtained from a composition that comprises diisocyanate; polysiloxane containing terminal hydroxyl groups; and polyol or polyamine containing at least one tertiary amino gorup. The derivatives of the polyurethane or polyurethaneurea is obtained by the following steps of: converting the tertiary amino groups contained in the polyurethane or the polyurethaneurea to quarternary ammonium groups, and treating the polyurethane or the polyurethaneurea having quarternary ammonium groups with heparin.

    摘要： Delay distribution in an integrated circuit is calculated while taking into account a correlation of performance between interconnects or elements in the integrated circuit, thereby improving estimation accuracy. Circuit information, performance distribution information of the interconnects or elements in the integrated circuit, and correlation information of performance between the interconnects or elements are input. A vertex is selected for calculation, and a correlation between delay distribution at the selected vertex and delay distribution in a partial circuit including the selected vertex is calculated based on the performance distribution information and the correlation information.
