PIEZOELECTRIC ELEMENT DRIVING APPARATUS AND COATING APPARATUS |
| 摘要 |
<p>A voltage of a direct current power supply (1) is boosted by a boost circuit (3) and applied to a piezoelectric element (6), and a charged voltage of the piezo element (6) is discharged by a discharge circuit (4). Thus, the piezoelectric element is surely charged to a level required for suction and ejection of a liquid, and cost increase and power loss are eliminated.</p> |
