    摘要： A method of manufacturing a functional part of synthetic resin material in a bearing plate so as to have good bearing properties. The functional part is formed at a bearing plate by a synthetic-resin injection-molding technique (outsert molding technique) with a bridge portion extending through a hole having hole walls of the bearing plate and with integral retaining portions disposed at both plate surfaces laterally of the hole. The functional part consisting of the bridge portion and the retaining pieces is then changed by a deformation process following the injection-molding operation so that it forms a rotation or slide bearing together with the bearing plate. In the deformation process, the synthetic resin material is pressed away by a mandrel acting on an internal wall of a bore in the bridge portion to cause the synthetic material to flow towards the hole wall of the bearing plate and longitudinally towards the plate surfaces. A load-resistant, partial molecular re-orientation is obtained, which may be rendered heat-resistant after the deformation through fixation and possibly by storing.

    摘要： A magnetic-tape cassette apparatus having a deck for magnetic-tape cassettes with a reel drive mechanism for transporting a tape with a first and an opposite, second tape transport direction. The change-over from the first tape transport direction to the opposite second tape transport direction is affected by a switching mechanism which switches the reel-drive mechanism between a play mode in the forward direction and a play mode in the reverse direction. The switching mechanism includes a switching lever moveable from a first position for the first playing direction to a second position for the opposite second play direction. The switching lever is moved by a pair of switching wheels, whose teeth are engageable with associated teeth of adjacent flywheels for changing over the switching lever from the predetermined position for one playing direction to the predetermined position for the opposite other playing direction by actuating elements provided on the switching wheels.
