    • The durability of a belt is enhanced by improving the strength of rubber itself while enhancing its peeling strength with respect to a cord, a fabric or a short fiber. A toothed belt (10) comprises a belt body (13) that is integrally formed by a tooth rubber (11) provided on one surface side thereof, a backing rubber (12) provided on the other surface side, and an embedded cord (14) spirally wound in a boundary portion between the tooth rubber (11) and the backing rubber (12) that extends in the longitudinal direction of the belt. A facing fabric (20) covering the tooth rubber (11) is adhered to a surface of the tooth rubber (11), or one surface of the belt body (13). The tooth rubber (11) is obtained by vulcanization-molding a rubber composition including rubber such as HNBR, resorcinol, a melamine compound, silica and the like.

    • A thickness extensional piezoelectric resonator utilizes harmonics of a thickness extensional vibration mode and has a significantly reduced size and significantly increased capacitance while not being susceptible to the effects of the stray capacitance of a circuit board upon which the resonator is mounted. The resonator includes a piezoelectric strip, first and second excitation electrodes located on one of two respective major surfaces of the piezoelectric strip, and internal electrodes disposed inside the piezoelectric strip. The first and second excitation electrodes are located on opposite sides of the piezoelectric strip. The internal electrodes are located opposite to the first and second excitation electrodes to thereby define a vibrating portion. Vibration-attenuating portions are located on opposite sides of the vibrating portion only along the longitudinal direction of the piezoelectric strip. No vibration-attenuating portions are located in the lateral direction of the piezoelectric strip.

    • 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.
