Abstract
Abstract A method and arrangement for the positioning and bonding of a solid body (2), in which one part of the solid body (2) together with the bonding agent (6) is to be attached to a further element (7) and bonded to a base (4) is to be capable of positioning the solid body (2), at the point attained after positioning, with both high precision and high long term stability. The solid body (2) is immersed in the bonding agent (6) and this bonding agent is in turn located in a groove of a further electrically conducting body (7). The further body (7) is heated by current flow to a temperature at which the solid body (2) is movable within the bonding agent. Upon attaining the desired positioning of the solid body (2), the bonding agent is allowed to cool through controlled reduction of the heating current until solidification occurs.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
142 words
A device for positioning and fastening a lightwave guide to a base with a fastening material, wherein a support means supports the lightwave guide and the fastening material and the base is adapted to include a laser diode, the device comprising: a first manipulator including a first electrode and a second electrode, the support means being clampable between the electrodes such that the manipulator is adapted to position the lightwave guide relative to the base, wherein an electric current passes through the electrodes such that the support means supplies heat energy to the fastening material; and a second manipulator adapted to grip and position the lightwave guide, wherein the first and second manipulators cooperate to position the lightwave guide; the support means being separable from the lightwave guide and the fastening material subsequent to fastening the light wave guide to the base.
Claim 2
Independent Claim
142 words
A device for positioning and fastening a lightwave guide to a base with a fastening material, wherein a support means supports the lightwave guide and the fastening material and the base is adapted to include a laser diode, the device comprising: a first manipulator including a first electrode and a second electrode, the support means being clampable between the electrodes such that the manipulator is adapted to position the lightwave guide relative to the base, wherein an electric current passes through the electrodes such that the support means supplies heat energy to the fastening material; and a second manipulator adapted to grip and position the lightwave guide, wherein the first and second manipulators cooperate to position the lightwave guide; the support means being separable from the lightwave guide and the fastening material subsequent to fastening the light wave guide to the base.
