摘要： A tuning-fork type piezoelectric vibratory gyroscope includes a tuning fork having two arms and a base portion integrally formed with the two arms and having electrodes, and a supporting base supporting the base portion of the tuning fork. An adhesive layer joins the base portion and the supporting base together so that the tuning fork and the supporting plate are elastically integrated within a temperature range in which the gyroscope is used.

摘要： A tuning fork type vibrator including two arms and a base is supported by a supporting substrate mounted on a stem, and an oscillation limiting member formed from a ring-shaped rubber-like elastic body is mounted with its one face secured to the stem so as to surround the base. When an external vibration or impact is applied, the tuning fork type vibrator oscillates in response to the vibration or impact, but the oscillation range of the tuning fork type vibrator is limited by the presence of this oscillation limiting member, and thus bumping of the tuning fork type vibrator against the surrounding members such as the stem is prevented. Moreover, a gyro characteristic is not impaired, and a loss of the gyro function due to a stop of drive vibration does not occur.
摘要翻译：包括两个臂和一个基座的音叉型振动器由安装在杆上的支撑基板支撑，并且由环形橡胶状弹性体形成的振动限制构件安装成其一个面固定到杆上，以便围绕基地。当施加外部振动或冲击时，音叉型振动器响应于振动或冲击而振荡，但是音叉式振动器的振荡范围受到该振动限制构件的存在的限制，因此调谐防止叉形振动器抵靠诸如杆的周围构件。此外，陀螺特性不受损害，并且不会发生由于驱动振动的停止引起的陀螺功能的损失。

摘要： The shape of drive electrodes and/or the shape of detection electrodes of a tuning fork type vibration gyro are made asymmetrical between the inside and outside of the arm, and between the surface and reverse face of the arm, to reduce the abnormal vibration and leaking output. The drive electrodes to be provided on the inside parts of the surface and reverse face of the first arm are formed smaller than the drive electrodes to be provided on the outside parts of the surface and reverse face thereof. The length of the detection electrode to be provided on the outside lateral face of the second arm is formed short. The drive electrodes to be provided on the surface and reverse face of the first arm are extended to the base side from the boundary position between the first arm and the base, and the detection electrodes to be provided on the surface and reverse face of the second arm are extended to the base side from the boundary position between the second arm and the base.

摘要： In a tuning fork type vibration element provided in a tuning fork type vibration gyro, the sum of inertial moments of a base to an inertial moment of two arms is 1.0 or larger. The inertial moment of the two arms is obtained by multiplying the square of a rotation radius, which is a distance from a center axis of torsional vibration as a center position between the two arms to a center of gravity of the two arms with a mass of the two arms, and the inertial moment of the base is obtained by multiplying the square of the rotation radius from the center axis of the same torsional vibration.
