摘要： In order to preserve good droplet discharge efficiency in a droplet discharge device, a plurality of timings are set within a period in which a plurality of droplets are to be discharged to a target position. Consecutive timings are divided by a cycle time of pressure wave that is generated inside a pressure chamber by transmitting a signal to an actuator. When a plurality of signals are applied to the actuator at consecutive timings, the peak of the pressure wave and the application of the signals are synchronous, and the droplet discharge efficiency will be improved. However, the consecutive number of timings at which the consecutive signals are transmitted is limited to a predetermined number. In this way, the pressure inside the pressure chamber can be prevented from becoming too high.
摘要翻译：为了在液滴喷射装置中保持良好的液滴喷射效率，在将多个液滴排出到目标位置的期间内设定多个定时。连续定时除以通过向致动器发送信号在压力室内产生的压力波的循环时间。当多个信号以连续的定时施加到致动器时，压力波的峰值和信号的施加是同步的，并且将提高液滴的排出效率。然而，发送连续信号的连续定时数被限制为预定数量。以这种方式，可以防止压力室内的压力变得太高。

摘要： A liquid discharge device (1) has a pressure chamber (3), a nozzle (4), and a communication path (5) that interconnects the pressure chamber (3) and the nozzle (4). A region that has a specific length L1 and lies from the position (8) of the boundary between the communication path (5) of the pressure chamber (3) toward the nozzle (4) is formed as a narrow section (9) that has an opening area S1 smaller than the opening area S0 of a region closer to the nozzle (4) than the narrow section (9). In the liquid discharge device (1), the narrow section (9) functions to damp micro vibration that occurs in liquid in the communication path (5), and this allows liquid drops having a pre-designed volume and flying speed to be discharged from every nozzle (4) on a board (2)
