る。 Mechanical oscillators are used in wave generators and oscillators, and are constructed by bonding a piezoelectric porcelain plate made of barium titanate, lead zirconate, or the like to an elastic body such as a constant-modulus alloy with an epoxy-based organic material or solder. The piezoelectric ceramic plate used is one to which a high DC voltage is applied in advance to generate residual polarization, and the phase characteristics of the mechanical vibrator vary depending on the directionality (polarity) of this residual polarization. The phase characteristics of this mechanical oscillator become an important element when constructing wave generators and oscillators.
