Abstract: A brushless DC motor system includes a multi-pole DC motor having coils and permanent magnets. Optically scannable markers are applied on the circumference of a rotating member of the motor in fixed association with the magnets. By means of a scanner, these markers are converted to signals. These signals are evaluated with respect to their phase position and moment of commutation, and as a result commutation current is supplied to the coils.

Abstract: A resilient scanning or recording head support made of deformable material comprising a resilient molded part being step like shaped and resiliently deformable in at least one direction and/or through an angle. This construction accommodates deflection of the scanning head analogously to a parallel guide, in a straight line as well as through at least one angle deviating from the preferred directions of the parallel guide.

Abstract: The invention relates to a gear rack arrangement, which, for the compensation of backlash, comprises two gear racks (A, B) which are mutually displaceable on latch elements and are resiliently braced, and refers both to the assembly and disassembly characteristics of the gear rack arrangement and to the number of moulded elements used. Application is envisaged, in particular, for a positioning device in a recording and reproducing instrument for optical recording carriers, although the field of application is not however thereby restricted. According to the invention, an anti-detachment safeguard is provided, which is formed by an elastic boss (F). In order to prevent the detachment of a second gear rack (B) from a first gear rack (A) during the assembly or disassembly, the elastic boss (E) is provided at one end of one of the gear racks (A, B). Furthermore, a latch element (C, D) is provided as counter-rest for a means which braces the gear racks (A, B), whereby the number and shapes of necessary moulded elements is reduced. The field of application relates to the manufacture and to the assembly and disassembly of gear rack arrangements comprising, for the compensation of backlash, two gear racks (A, B).

Abstract: A drum for a rotatable cylinder head includes an opaque disc-shaped member having a plurality of opaque fins affixed thereto and arranged substantially normal to the disc-shaped member. A first plurality of the fins has a first width and a second plurality of the fins has a second width broader than the first width. Every fin has a distal end remote from the disc-shaped member, and an opaque circumferential ring is affixed to the distal end of each fin. The disc-shaped member, the fins and the circumferential ring form a plurality of apertures about the drum.
