  • Patent number: 8732924
    Abstract: A method of manufacturing a piezoelectric vibrator comprises supporting a piezoelectric vibration element in a case by a conductive bonding member, the piezoelectric vibration element having a metal layer formed on a piezoelectric substrate formed of a thickness shear based piezoelectric material, and adding or reducing a thickness of the metal layer to adjust a resonant frequency of the piezoelectric vibration element to a predetermined value. The method also comprises leaving the case into an atmosphere filled with vapor of a material having a nonbonding electron pair, making the metal layer resultantly exposed to the vapor subject to chemical absorption with the material having the nonbonding electron pair, and hermetically encapsulating the case in a state substituted by an inert gas atmosphere.

  • Publication number: 20130195282
    Abstract: An active vibration noise control device is preferably used for canceling a vibration noise by making a speaker generate a control sound. Concretely, the active vibration noise control device includes an attenuating unit which attenuates a control signal generated by an adaptive notch filter, and provides the attenuated control signal to the speaker, when amplitude of a filter coefficient is larger than a threshold. Therefore, it is possible to suppress continuous ups and downs of the filter coefficient during an occurrence of an abnormality. Hence, it becomes possible to appropriately suppress an occurrence of a cyclic abnormal sound and an increase in the vibration noise during the occurrence of the abnormality.
