Embodiment 41
[0128] Examples 41 to 42 are examples of the third embodiment. In Example 41, the detection of droplet detachment was implemented. In Example 42, after setting the slope period during the first and second pulse rising periods and the first pulse falling period, it was implemented. Droplet detachment detection.
[0129] Examples 43 to 47 are examples of the third embodiment. Examples 43 to 44 overlap high-frequency pulses. Example 45 overlaps after setting a slope period during the rising period of the first and second pulses and during the falling period of the first pulse. In Example 47, droplet detachment detection was performed after the first and second pulse rising periods and the first pulse falling period provided a slope period, and high-frequency pulses were superimposed.
[0130] Next, comparative examples shown in Table 6 will be described. However, these Comparative Examples 48 to 61 satisfy the scope of the present invention. In Comparative Example 48, there is ...
