摘要： A head drive of an inkjet printer includes nozzles and corresponding actuators that eject liquid ink drops. A drive unit applies a drive signal to the actuators. The drive unit includes a drive waveform generator that generates a drive waveform signal to control the drive of the actuators. A modulator pulse modulates the drive waveform. A digital power amplifier amplifies power of the modulated signal. A low pass filter smoothes the amplified digital signal and supplies the signal as a drive signal to the actuators. An inverse filter provided in a subsequent stage of the drive waveform generator corrects at least the frequency characteristics of the filter to predetermined frequency characteristics, independent of the number of the actuators to drive.

摘要： A thin film composed of a material containing a metal and silicon is formed on a transparent substrate, and a thin film pattern is formed by patterning the thin film. Then, the main surface and the side walls of the thin film pattern are previously modified so as to prevent the transfer characteristics of the thin film pattern from changing more than predetermined even in the case where exposure light with a wavelength of 200 nm or less is cumulatively applied onto the thin film pattern which has been formed. The main surface and the side walls are modified by, for instance, performing heat treatment to the main surface and the side walls at 450-900° C. in the atmosphere containing oxygen.
