Title: Drive circuit of piezoelectric transformer
Inventor: NAKANISHI HIDEYUKI
IPC: H02M7/537
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To obtain a drive pulse with a low-frequency clock and a frequency high resolution by setting the average frequency-division ratio of a specific cycle period nearly equal to a value that is obtained by dividing specified bit data being outputted from a frequency-setting circuit by a specific value, and setting the fluctuation of the frequency-division ratio within the specific cycle period to a specific value or less. SOLUTION: An error voltage is outputted in synchronism with a smoothing cycle period from an error voltage operation circuit 8 in synchronism with a master clock, and the error voltage and a current frequency setting value are added and outputted in synchronism with pulses with only different delay timings at the same cycle as the smoothing cycle pulse in a frequency setting circuit 9. The outputted data is the upper three-bit data (frequency division ratio) of data (five bits) being outputted from each frequency setting circuit 9 and the lower two-bit data (dispersion). The number of dispersion is set by the lower two bits out of the five-bit data being outputted from the frequency setting circuit 9 since the number N of dispersion is equal to four.  An operation is made so that the clock cycle of the four cycle periods of a drive pulse being obtained by frequency division becomes equal to a frequency setting value, thus improving average frequency resolution.

Filed: 1989-11-30
Abstract: PURPOSE:To enhance pulverization characteristics and to obtain a high turn- down ratio by integrally forming a vibrator horn having a protruding continuous curved shape to the leading end of a vibrator main body. CONSTITUTION:A liquid supply pipe 7 is connected to an annular liquid storage part 6 in a tangential direction and imparts revolving force to the liquid flowing in the liquid storage part 6. Even when the clearance of a nozzle part 2a is increased and the generation of cavitation is reduced, the liquid is uniformly supplied toward a vibrator horn 3a by the revolving force of the liquid and atomized herein by the ultrasonic vibration excited by an electroacoustic converter 4. Since the liquid sprayed from the nozzle part 2a smoothly flows along the vibrator horn 3a having a protruding continuous curved shape, even when the supply flow rate of the liquid is increased, pulverization characteristics can be enhanced and a spray angle can be narrowed.
