  • Planar transformer
    Patent number: 6307457
    Abstract: Planar windings of the secondary coil have outward extending portions which on the outside, so that the vias are situated at a larger distance from the core. In a planar transformer, also the turns of the primary coil may extend parallel to each other. In this manner, it is possible to further reduce the size of the transformer, while the power loss is minimal.

  • Record-disc player comprising a braking mechanism for braking a disc
    Patent number: 4562563
    Abstract: In a record-disc player comprising a disc-braking mechanism the turntable (7) is covered by a lid (14) which is pivotally connected to a housing (3). The lid (14) is latched in a closed position by means of a latching mechanism (30). A brake lever (21) is pivotally connected to the lid (14) and carries a braking element (23) and a stop element (24) arranged on opposite sides of the pivot. The latching mechanism (30) can be released by exerting pressure on the lid (14), the stop element (24) engaging with a stop portion (44) as a result of the pressure exerted on the lid. By the pivotal movement of the lever (21) relative to the lid (14) a braking torque is exerted on the disc loader (20) by the braking element (23), so that the disc (13) is stopped.
