Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Piezoelectric transducers; Electrostrictive transducers > Resonant transducers, i.e. adapted to produce maximum output at a predetermined frequency
CPC:
Piezoelectric transducers; Electrostrictive transducers (piezoelectric or electrostrictive elements in general H10N30/00; details of piezoelectric or electrostrictive motors, generators or positioners ) > Resonant transducers, i.e. adapted to produce maximum output at a predetermined frequency
No child classifications to compare. This is a leaf node in both IPC and CPC.
