A method for exactly aligning at least two holograms arranged in optical waveguides with respect to one another includes writing a first hologram and a first mark in a first optical waveguide. The method also includes writing a second hologram and a second mark in a second optical waveguide. The method further includes positioning the first optical waveguide and the second optical waveguide with respect to one another. The method also includes illuminating the first mark and the second mark. A pattern occurring during the illumination after passing the first mark and the second mark is detected. The method further includes changing the position of one of the optical waveguides until the detected pattern matches a specified pattern.

In a linear drive device, a movable member is driven using a guide shaft and a lead screw supported by a bracket. Since a nut mechanism, which with the lead screw configures a feed screw mechanism, is provided with a first spring between two nuts, it is possible to limit rattling of the nuts with respect to the lead screw. Of the two nuts, the first nut provided on the side opposite a motor and a first plate is not able to move relative to the movable member in the axis direction. As a result, when a member to be driven is loaded on the movable member and the movable member is driven in the direction approaching the first plate, the first plate and members disposed therearound are not susceptible to interference by the member being driven.

A ceiling-supported suspension mechanism for a piece of equipment, in particular for operating lights, has a pivot arm, as extension, which is arranged on the rotary bearing of a ceiling mount such that it can be rotated about a vertical axis. The pivot arm has two sub-arms which are connected to one another by an intermediate articulation which can be rotated about a vertical axis. The two sub-arms of the pivot arm are arranged at the same height such that they can be pivoted in a horizontal plane. The intermediate articulation can be pivoted merely in a limited angle range of up to 110&deg;, as a result of internal stops. The sub-arm which is remote from the rotary articulation is provided, at its outer end, with an articulation which can likewise be rotated about a vertical axis and on which there is fastened a carrying arm for the suspension mechanism. It is possible for the carrying arm to be pivoted through 360&deg;.
