A method of evaluating an integrated circuit design selects manufacturing parameters of interest which are outside of manufacturing specification limits. Furthermore, in the same scroll compressor, tip seals are provided respectively in two grooves, and join paths are provided respectively between a high-pressure compression chamber, which is formed with the bottom faces as one section, and the two grooves; the pressure inside the high-pressure compression chamber is used as a pressing force for the tip seals. CM-247 LC material is heated in a vacuum furnace at a rate of about 0. Ph4 represents a p-phenylene group, and at least one of Ph4a and Ph4b represents a p-phenylene group. That is, the characteristic of the MZ interferometers are evaluated by using a side band intensity of the component other than the 0-degree component.
