A coated substrate, such as thick, coated metal sheet is made using a system where a moving metal sheet substrate, preferably aluminum over 0. Therefore, the liquid crystal display device synchronizes with a timing of supplying the active signal with the first scan line drive circuit and the second scan line drive circuit, and supplies a data signal whose polarity is inverted to a positive polarity potential and a negative polarity potential per one horizontal scan period, to a data line. Also disclosed is the preparation of compounds of Formula IV wherein X1, R6, R7, R8a, R8b, R9, and n are as defined in the disclosure. The injector system further includes a base unit having a base member that is attachable to a surface and a support member to which the connecting member is attachable. Each sector can be displayed individually or together with other sectors so that the human operator can easily analyze the results. As a result, it is possible to supply the ink at a substantially constant pressure to the recording head without regard to the variation in the amount of ink or the movement of the carriage.
