  • Angular velocity sensor making use of tuning fork vibration
    Patent number: 5488863
    Abstract: The present invention relates to an angular velocity sensor comprising a tuning fork vibrator which exerts a tuning fork vibration by receiving a driving input and which generates a torque around the axis of a tuning fork owing to Coriolis force by undergoing a rotational action around the center of the tuning fork. The sensor has a detection torsional vibrator which exerts torsional vibration owing to the torque generated by the tuning fork vibrator, whereby the angular velocity sensor detects a rotational angular velocity around the axis of the tuning fork based upon the magnitude of the vibration of the detection torsional vibrator. At least one buffer torsional vibrator is positioned around the detection torsional vibrator for moderating external transmission energy loss of the torsional vibration of the detection torsional vibrator.
