摘要： An energy-trap type piezoelectric resonator utilizes a fundamental wave of a thickness shear vibration mode and includes resonance electrodes provided on both main surfaces of a substantially rectangular piezoelectric plate so as to face each other with the piezoelectric plate disposed therebetween. An energy trap vibration portion including a portion of the piezoelectric plate where the resonance electrodes overlap each other is asymmetrical with respect to the center in the longitudinal direction of the piezoelectric plate.

摘要： A rubber-modified phenolic resin composition contains a novolak-type phenolic resin in which at least one modifying agent selected from the group consisting of an ABS resin and an MBS resin is homogeneously dispersed. The composition has good impact resistance and thermal shock resistance. The composition is prepared by adding at least one modifying agent described above to a novolak-type phenolic resin which is heated and melted at its softening point or more, so that the modifying agent is homogeneous dispersed in the resin. The resin composition is suitably used as a curing agent for an epoxy resin encapsulant for sealing electronic devices.
