摘要： A piezoelectric resonator component includes an energy-trapped piezoelectric resonator utilizing a third order harmonic wave of thickness longitudinal vibration and including a piezoelectric substrate having first and second major surfaces and polarized in a direction of thickness between the first and second major surfaces, and first and second vibrating electrodes opposed to each other with the piezoelectric substrate interposed therebetween, and first and second casing substrates respectively laminated on the first and second major surfaces of the piezoelectric resonator so that cavities are arranged so as not to interfere with vibration of a vibration section where the first and second vibrating electrodes face each other through the piezoelectric substrate. The first and second vibrating electrodes are dimensioned so that the difference between the peak values of the phases of S0 and S1 modes of the fundamental wave of the thickness longitudinal vibration falls within a range of about ±5 degrees.

摘要： An energy trap type piezoelectric resonator component includes a piezoelectric resonator using a third overtone of a thickness longitudinal vibration. The piezoelectric resonator includes a piezoelectric substrate, and first and second vibrating electrodes, having an elliptical shape, and respectively arranged on portions of first and second major surfaces of the piezoelectric substrate such that the first and second vibrating electrodes face each other with the piezoelectric substrate interposed therebetween. A flattening ratio “a/b” of a minor axis diameter “b” to a major axis diameter “a” of the elliptical shape is within a range of from about 1.2 to about 1.45. The resonator is thus compact, effectively controls the fundamental wave of the thickness longitudinal vibration as a spurious wave, is relatively free from area restraints of the electrode and dimensional constraints, and meets a variety of frequency requirements in a wide range.

摘要： A piezoelectric device is essentially composed of a piezoelectric transducer and a light transmitting protector. The protector is made of heat resisting glass, heat resisting acrylic, transparent ceramics or the like. By exposing the piezoelectric device to a laser beam and thereby causing it to penetrate through the protector to the piezoelectric transducer and to partly cut the surface of the piezoelectric transducer, or to change the intensity of polarization, mechanical coupling coefficient or dielectric constant of the piezoelectric transducer, its vibration frequency and resonance characteristic can be adjusted. If an ultraviolet-ray setting agent is used as adhesive, it can be hardened by exposing the piezoelectric device to ultraviolet rays to thereby cause it penetrate through the protector.
