摘要： Here disclosed is an angular velocity sensor with much accuracy, not allowing other vibration components to mix into the Coriolis force component. The angular velocity sensor contains a first through a fifth beams: the first, the second, and the third beams have a length of substantially the same and disposed in a substantially parallel arrangement on a substantially the same plane—with the first beam placed between the second and the third; the fourth connects each one end of the first through the third, while the fifth connects each other end of them. The first beam is supportively fixed at its mid-portion. The first beam serves as a detector; the second serves as a driver; and the third serves as a monitor.

摘要： A vibrating gyroscope includes supporting members which are fixed in the vicinity of two node axes n1 and n2 of a bar-shaped vibrator. The supporting members corresponding to node axis n1 extend from the locations at which they are fixed to the vibrator in the widthwise direction of the vibrator, and also include bending portions and a proximity portion. The bending portions bend toward node axis n1. At the proximity portion, the supporting members are in close proximity with each other with a gap therebetween in the vicinity of node axis n1.

摘要： A vibrating gyroscope includes a vibrator and an oscillation circuit for exciting the vibrator. Detecting terminals of the vibrator are connected to ground through load resistances, and are also connected to a differential circuit. A synchronous detection circuit detects a signal output from the differential circuit. A smoothing circuit smoothes a signal output from the synchronous detection circuit. An amplifying circuit amplifies a signal output from the smoothing circuit. Resistance values of the load resistances are adjusted depending on temperature drift gradient of the vibrating gyroscope, such that the temperature drift gradient is minimized.

摘要： Yaw rate sensors are provided, the use of which permits quantitative measurement of yaw rate. The yaw rate sensor comprises at least a base, a first suspension and a second suspension with a proof mass supported between the two suspensions, which together form a resonator. The first suspension has a pair of thin-wire driving electrodes double side patterned on the surfaces. When a driving voltage is applied to the driving electrodes, it imposes an electric field to piezoelectrically induce a driving resonance. When the sensor is rotated around its sensing axis, the resonator will be forced to generate a sensing resonance out of the driving resonance plane to compensate the change in the linear momentum which must be conserved. The piezoelectric charge signal generated by the sensing resonance on the sensing electrodes which are double side patterned on the surfaces of the second suspension is used to detect the yaw rate. Specifically, the amplitude of the sensing resonance is in proportion to the yaw rate. The structure of the yaw rate sensors of this invention is suitable for mass production by lithographic micromachining techniques at low cost.
摘要翻译：提供了速度传感器，其使用允许定量测量偏航率。横摆率传感器包括至少一个基座，第一悬架和第二悬架，其中两个悬架之间具有支撑在两个悬架之间的检测质量，这些共同构成共振器。第一悬架具有在表面上双面图案化的一对细线驱动电极。当驱动电压施加到驱动电极时，施加电场以压电引起驱动共振。当传感器围绕其感测轴线旋转时，谐振器将被迫从驱动谐振平面产生感测谐振，以补偿必须保守的线性动量的变化。通过在第二悬架的表面上双面图案化的感测电极上的感测谐振产生的压电充电信号用于检测偏航率。具体地，感测谐振的振幅与偏航率成比例。本发明的偏摆率传感器的结构适用于通过光刻微加工技术以低成本进行批量生产。

摘要： A structure and arrangement for improving the accuracy and efficiency of an angular rate sensing gyroscope is herein disclosed. Voltage pick-off conductors are applied to an area of the surface of a resonating element of an angular rate sensing gyroscope that is subject to substantially zero stress when the gyroscope is rotationally stationary. Actuator conductors are similarly applied to a resonating element at a location bounded by areas of the resonating element subject to substantially uniform levels of stress when the gyroscope is rotationally stationary. A method for improving the voltage response of a piezoelectric resonating element is also disclosed.
