<p>A vibrating gyroscope comprises a vibrating element which is polygonal, e.g., rectangular, in cross-section, at least two piezoelectric elements adhered to at least one side of the vibrating element, and a variable resistor. The variable resistor includes at least two fixed terminals and a variable terminal for varying the resistance of the variable resistor. The piezoelectric elements are connected to the two fixed terminals of the variable resistor, while the variable terminal is grounded. This brings the output voltages generated by the piezoelectric elements into phase thereby improving measurement of angular velocity. In a preferred embodiment, a fixed resistor is disposed between the variable terminal of the variable resistor and the ground potential. <IMAGE></p> |
