Abstract:
A combined sensor comprising a vibration gyro sensor and another sensor having a function different from that of said vibration gyro sensor; said vibration gyro sensor comprising at least one or more vibrators subjected to excited vibration effected by at least one or more driving means, a support base for supporting said vibrator at a proximal end thereof, at least one or more detecting sections including at least one or more detecting piezoelectric/electrostrictive elements for detecting displacement generated in a direction perpendicular to a direction of vibration of said vibrator when said vibrator is rotated, said detecting section composed of an integrated fired product made of ceramics together with said vibrator and said support base, said detecting section being constructed by a first plate-shaped section which is more thin-walled than said vibrator and which has a principal surface extending in said direction of vibration, said detecting piezoelectric/electrostrictive element formed in an integrated manner on said first plate-shaped section in accordance with a film formation method, at least one or more thin-walled second plate-shaped sections for decreasing rigidity in said direction of vibration and facilitating said vibration, said second plate-shaped section being provided for said vibrator in an integrated manner so that a principal surface thereof extends in said direction perpendicular to said direction of vibration, said support base constructed by an attachment frame positioned outside said vibrator and separated by predetermined spacing distances therefrom so that said vibrator is surrounded thereby, and said driving means provided in an integrated manner between said attachment frame and said vibrator; and said combined sensor further comprising a second attachment frame formed in an integrated manner with said attachment frame and provided adjacent to said attachment frame of said vibration gyro sensor; wherein said another sensor is supported in an integrated manner in said second attachment frame.
