发明名称 SYSTEM FOR ADJUSTING FREQUENCY OF PIEZOELECTRIC VIBRATOR
摘要 PURPOSE:To improve productivity by automatizing the adjustment of the frequency of a vibrator, by selecting an object frequency approaching extremely to the oscillation frequency of a quartz oscillator to be adjusted from the basic data accumulation part of a computer, and inputting it a controller. CONSTITUTION:A frequency adjusting system consists of a vapor depositing device 7 in which a metallic particle is attached on the electrode of an adjusting vibrator 1, the controller 30 which controls the output of the vapor depositing device 7, and the computer 40 which operates and drives the controller 30. A reading part 41 reads the oscillation frequency of the vibrator 1, and connects it to a data retrieval part 43. The retrieval part 43 selects the basic data approaching extremely to the vibrator 1 out of a large number of oscillation frequencies stored in the basic data accumulation part 42. An arithmetic part 44 calculates a frequency difference between the vibrator 1 and the basic data, and controls a power control circuit 33 and a shutter driving circuit 32.
