摘要： A tuning fork type vibrational gyroscope, wherein a tuning fork type oscillator having two arms and a base is supported on a supporting substrate installed on a stem, and an oscillation limiting member comprising an annular rubber elastic body is installed so that it surrounds the base with its one face fixed to the stem, whereby though, when a vibration or impact is given externally, the tuning fork type oscillator is oscillated according to the vibration or impact, the amplitude of the tuning fork type oscillator is limited by the presence of an oscillating limiting member so as to prevent the tuning fork type oscillator from impacting against surrounding members such as the stem, and a gyro characteristic is not impaired and also there is no possibility that a gyro function is lost due to stop of driving vibration.

摘要： An acceleration sensor, comprising a weight (12) and a vibrator (10) installed so as to support the weight at the gravity center thereof, wherein when the weight receives an acceleration, a stress according to the acceleration is produced in the vibrator, and since the vibrator is installed so as to support the gravity center of the weight, a specific relation is established between accelerations such as an angular acceleration and a translation acceleration and the magnitudes and polarities of generated charges, whereby different accelerations can be easily detected by using that relation.
