Abstract
Abstract An adjustment device for supporting and positioning an optical waveguide end portion, composed of: a supporting frame; a spring element supported by the frame for supporting the waveguide end portion; and device associated with the element for applying pressure thereto in two mutually orthogonal directions perpendicular to the axis of the waveguide end portion for positioning the waveguide end portion in a plane perpendicular to the waveguide end portion axis; wherein the spring element is an L-shaped angle piece having two arms meeting at a vertex, with the end of one arm remote from the vertex being fastened to the frame, and the end of the other arm remote from the vertex being arranged to support the waveguide end portion, and a respective one of the pressure applying devices acts on each one of the arms.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
An adjustment device for supporting and positioning an optical waveguide end portion, comprising: a supporting frame; a spring element supported by said frame for supporting the waveguide end portion; and means associated with said element for applying pressure thereto in two mutually orthogonal directions perpendicular to the axis of the waveguide end portion for positioning the waveguide end portion in a plane perpendicular to the waveguide end portion axis; wherein said spring element is an L-shaped angle piece having two arms meeting at a vertex, with the end of one said arm remote from said vertex being fastened to said frame, and the end of the other said arm remote from said vertex being arranged to support the waveguide end portion, and said pressure applying means act on each one of said arms.
Claim 2
Dependent Claim
133 words
An adjustment device for supporting and positioning an optical waveguide end portion, comprising: a supporting frame; a spring element supported by said frame for supporting the waveguide end portion; and means associated with said element for applying pressure thereto in two mutually orthogonal directions perpendicular to the axis of the waveguide end portion for positioning the waveguide end portion in a plane perpendicular to the waveguide end portion axis; wherein said spring element is an L-shaped angle piece having two arms meeting at a vertex, with the end of one said arm remote from said vertex being fastened to said frame, and the end of the other said arm remote from said vertex being arranged to support the waveguide end portion, and said pressure applying means act on each one of said arms.
Claim 3
Dependent Claim
46 words
Adjustment device as defined in claim 1 wherein said pressure applying means comprise a first pressure applying device engaging at said end of the said other arm which carries said supporting means, and a second pressure applying device engaging at said one arm near said vertex.
Claim 4
Dependent Claim
25 words
Adjustment device as defined in claim 2 wherein each said pressure applying device is a screw threaded in a respective passage in said supporting frame.
Claim 5
Dependent Claim
16 words
Adjustment device as defined in claim 1 wherein said angle piece is weakened at said vertex.
Claim 6
Dependent Claim
19 words
Adjustment device as defined in claim 1 wherein said two arms of said angle piece have respectively different elasticities.
Claim 7
Dependent Claim
27 words
Adjustment device as defined in claim 1 wherein said end of said other arm is provided with a bore in which the waveguide end portion is mounted.
Claim 8
Dependent Claim
22 words
Adjustment device as defined in claim 6 further comprising a capillary tube mounted in said bore for receiving the waveguide end portion.
Claim 9
Dependent Claim
37 words
Adjustment device as defined in claim 1 wherein said pressure applying means comprise two pressure applying screws each threaded in a respective passage in said supporting frame for applying pressure to a respective one of said arms.
