Abstract

A METHOD FOR ADJUSTING A RESONANCE FREQUENCY OF A PIEZOELECTRIC RESONATOR (1) THAT ALLOWS THE FREQUENCIES OF A PLURALITY OF PIEZOELECTRIC RESONATORS (1) TO BE ADJUSTED CONTINUOUSLY, EFFICIENTLY, AND ACCURATELY. A RESONANCE FREQUENCY OF A PIEZOELECTRIC RESONATOR 1 IS MEASURED BY USE OF A RESONANCE FREQUENCY MEASURING APPARATUS 5, AND AN OPENING TIME T OF A SHUTTER IS THEN DETERMINED BASED ON A DEVIATION OF A MEASURED RESONANCE FREQUENCY FR FROM A PREDESIGNATED FREQUENCY FR0, FR = FR – FR0. THEN, UV INK 13 INJECTED FROM A SPRAY NOZZLE 8 BY OPENING A SHUTTER DEVICE 9 ONLY FOR A TIME T IS APPLIED TO AN ELECTRODE 3 OF THE PIEZOELECTRIC RESONATOR 1. THEREAFTER, A RESONANCE FREQUENCY OF THE PIEZOELECTRIC RESONATOR 1 IS REMEASURED BY USE OF A RESONANCE FREQUENCY MEASURING APPARATUS 14, AND THERE IS CORRECTED A RELATIONSHIP DETERMINING THE OPENING TIME OF THE ABOVE SHUTTER DEVICE 9 BASED ON A DEVIATION OF A MEASURED RESONANCE FREQUENCY FR FROM A PREDESIGNATED FREQUENCY FRO, FR = FR - FRO. THE OBTAINED DATA ARE FED BACK TO AN APPARATUS FOR APPLICATION 6.
