There are provided a compound represented by a general formula shown below suitable as an acid generator for a resist composition, a compound represented by a general formula shown below suitable as a precursor for the compound represented by the general formula, an acid generator, a resist composition, and a method of forming a resist pattern. The alignment film includes a plurality of alignment molecules including polyamic acid andor polyimide and a plurality of photo-sensitive molecules including terphenyl andor substituted terphenyl, wherein a mass ratio of the plurality of alignment molecules to the plurality of photo-sensitive molecules is 3\u02dc7%:0. The circuit boards in the first array are cooled through a separate airflow path, which preferably also runs front-to-rear. Accordingly, when a BIOS-setting read request is issued from the outside, the management-module controller makes the response to the request source by reading the data stored into the backup memory area. Values for at least n12, \u03bd12, fw and ft are appropriately set based on predetermined conditions. An improved color management system is provided that improves image contrast and facilitates color management suitable for use in adverse thermal environments without requiring costly, high index, low birefringence glass via coupling the color selector and the analyzer to the light combiner.
