The present invention provides a fluoroalkyl-group-containing compound that has high water solubility and is highly capable of reducing the surface tension of an aqueous composition. Especially, an integrated circuit which is formed by a thin film is extremely thin, and so there is a threat that the integrated circuit is flied when transporting, and so handling thereof is difficult. The first data set is stored on a first storage medium. A control IC in the printer converts the storage format of addressing, before writing information into cartridge’s storage elements. The two blade portions may have distinct angles of incidence.
