Abstract
A vibrating gyroscope includes a vibrator having a node and a support member having a thin flexible portion and an expanded portion which is connected to the thin flexibly portion and has a larger area than the thin flexible portion. The expanded portion of the support member is fixed to the vibrator at the node.
Claims20
A vibrating gyroscope, comprising:
- a vibrator having at least two nodes;
- and
- support members sandwiching said at least two nodes in a vertical direction of the vibrator, and extending in a direction that is perpendicular to the vertical direction and to a longitudinal direction of the vibrator;
- wherein
- said support members include bent portions, the bent portions of the support members are arranged such that the bent portion of the support member at an upper side of said at least two nodes and the bent portion of the support member at a lower side of said at least two nodes are bent in opposite directions to each other with respect to the longitudinal direction of the vibrator.
2 more elements
A vibrating gyroscope, comprising:
- a vibrator having at least a first node and first and second principal surfaces which are parallel with each other;
- and
- first and second support members made of a thin plate and provided on the first and second principal surfaces of the vibrator, respectively, such that the first and second support members sandwich the at least first node of the vibrator in a vertical direction of the vibrator, the first and second support members extending in a direction that is perpendicular to the vertical direction and to a longitudinal direction of the vibrator;
- wherein
- the thin plates of the first and second support members are bent in opposite directions to each other with respect to the longitudinal direction of the vibrator.
2 more elements
A vibrating gyroscope comprising:
- a vibrator having at least one node;
- and
- support members sandwiching said at least one node in a vertical direction of the vibrator;
- wherein
- a plane includes said at least one node, and said plane is substantially perpendicular to a longitudinal direction of the vibrator;
- and
- said support members are arranged such that one end of the support member at an upper side is fixed at a first position away from said plane with respect to the longitudinal direction of the vibrator and one end of the support member at a lower side is fixed at a second position across said plane from the first position.
