1. How does the cleaning effect change when the oscillation method is changed?

   Single-frequency oscillation tends to cause cleaning irregularities in the depth direction due to the effect that position of nodes and antinodes are fixed by standing waves.
   Frequency modulation methods (DUAL, F.M./Sweep, Multi, etc.) change the phase of the nodes and antinodes of wavelength and tend to reduce cleaning irregularities in the depth direction.　Especially with DUAL oscillation, ultrasonic waves tend to propagate farther, which is advantageous when the liquid depth is deep.
