摘要： With an appropriate signal transmission form, a drive pulse output circuit is mounted to an ink jet head, so that waveform distortion of an actuator drive pulse for jet of ink drops is inhibited or prevented. Modulated signal data in memory is read to output a modulated signal, which is power-amplified by a digital power amplifier. The amplified digital signal is smoothed to be output to an actuator as a drive pulse. As a result, the digital power amplifier having high amplification efficiency efficiently amplifies the power of the modulated signal, thereby eliminating the need to use a cooling unit. The drive pulse output circuit can be mounted to the ink jet heads, thereby shortening the transmission path of an actuator drive pulse, which inhibits or prevents any waveform distortion of the drive pulse. The transmission of the modulated signal data DATA is implemented with a low frequency.

摘要： The present invention provides a rotation controller adjusting the speed of a rotary member (103). Phase difference compensating means (118) outputs a phase difference compensating signal (119) corresponding to a phase difference between a rotation signal of the rotary member (103) and a target signal, and frequency difference compensating means (114) outputs a frequency difference compensating signal (115) corresponding to a frequency difference between these signals. The rotary member (103) is braking-controlled by means of these signals. Use of the phase difference compensating signal (119) permits achievement of PLL control, and maintenance within the locking range allows a stable rotation control with a high response. Further, use of the frequency difference compensating signal (115) makes it possible to quickly bring the control within the locking range even when the rotary member (103) deviates from the target signal, and thus to carry out a control with a high response even upon riseup of the rotary member (103).
