Vibrators, vibratory gyroscopes, devices for measuring a linear acceleration and a method of measuring a turning angular rate

A vibratory gyroscope for detecting a turning angular rate around a turning axis comprising:

• a vibrator to be turned around said turning axis and having a center of gravity (GO), said vibrator comprising:
• a first vibration system whose vibration includes two or more radial vibration components with respect to an imaginary circle whose center is coincident with said center of gravity of said vibrator, a second vibration system whose vibration includes a circumferential vibration component with respect to an imaginary circle whose center is coincident with said center of gravity of said vibrator, and a base portion, wherein said first vibration system, said second vibration system and said base portion are formed along a specified plane intersecting said turning axis, and wherein said first vibration system and said second vibration system are connected through said base portion;
• exciting means provided in one of said first vibration system and said second vibration system for exciting a driving vibration in said vibrator;
• and
• detecting means provided in the other of said first vibration system and second vibration system for detecting a detecting vibration that occurs due to Coriolis force in said vibrator when said vibrator is turned around said turning axis.
