Abstract
Abstract A device for precision displacement of a solid body with respect to a bearing surface, having at least two supports of elastic material, each of the supports being rigidly fixed at one end thereof to the displaceable solid body, and at least two drive means for ensuring independent movement of the ends of each support both in the direction perpendicular to the bearing surface, and in the direction of movement of the solid body.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A device for a precision displacement of a solid body with respect to a bearing surface, comprising at least two supports of elastic material, each of said supports being rigidly fixed at one end thereof to said solid body, and at least two drive means for each support to ensure independent movement of the ends of each support both in the direction perpendicular to said bearing surface, and in the direction of movement of said solid body.
Claim 2
Independent Claim
77 words
A device for a precision displacement of a solid body with respect to a bearing surface, comprising at least two supports of elastic material, each of said supports being rigidly fixed at one end thereof to said solid body, and at least two drive means for each support to ensure independent movement of the ends of each support both in the direction perpendicular to said bearing surface, and in the direction of movement of said solid body.
Claim 3
Dependent Claim
104 words
The device, as claimed in claim 1, wherein said drive means comprises a control unit providing for the alternate displacement of the ends of said supports, and transducers to convert the signals of said control unit into such displacements, at least two transducers being secured on each said support, the first of said transducers being mounted so as to provide for displacements of the ends of said supports in the direction perpendicular to said bearing surface, while the second of said transducers are mounted so as to effect displacement of the ends of said supports in the direction of movement of said solid body.
Claim 4
Dependent Claim
22 words
The device, as claimed in Claim 2, wherein employed as said transducers of the control unit signals into displacement are piezoelectric transducers.
