Abstract
A gyro which realizes a small error response to a disturbance inertia such as vibration, impact, etc. and an adjusting system thereof has a pair of mass elements which are cyclically driven symmetrically. A pair of sensors independently detect forces produced in response to an input angular rate and generate a pair of detection outputs. An adjustable adder synthesizes components proportional to the disturbance inertia contained in the detection outputs with an optimum addition ratio so that they are mutually completely cancelled and generates a synthesized output. A signal processing circuit processes the synthesized output to generate an output proportional to the input angular rate. The adjusting system applies to the gyro in an operating condition a disturbance vibration in the vicinity of the drive frequency of the gyro. By adjusting the addition ratio of the adjustable adder in a manner so as to make the response at this time a minimum, the best characteristic can be obtained.
