摘要： A method for logic design of an integrated circuit IC in which at least one parameter concerning wiring line capacitances is used. The parameter can be precisely estimated even at a logic design stage preceding a layout design stage. The estimation is carried out by, first, classifying the logic units or the logic gates of the IC into hierarchal functional blocks. Second, specifying, for each closed network defined by delay paths, a higher level functional block in which the closed network is contained. Third, specifying lower level functional blocks enclosed by the higher functional block. Fourth, calculating the estimated wiring line capacitances of the closed network in accordance with predetermined data concerning both fan-out and actual wiring line capacitances. The data, used for the estimation, are varied in accordance with the degrees of the hierarchal level.

摘要： A prevention against shifting of tip seal of a scroll compressor with a pair of stationary scroll and swirl scroll provided with spiral laps projectingly on an inside of end plates engaged with each other for sucking in a gas from a suction port and discharging a compressed gas from a discharge port, wherein a tip seal groove is formed on the laps provided projectingly on said pair of scrolls, a tip seal is disposed in the tip seal groove, which comprises providing a fixing means for preventing a discharge port side end portion of the tip seal disposed in said tip seal groove from shifting to a suction port side from a discharge port side along said tip seal groove, thereby preventing a leakage of a lap nose on the discharge port side.
