Abstract: The invention relates to a device (1) for generating X-rays (57). The device comprises a source (7) for emitting electrons (53) and a liquid metal for emitting X-rays as a result of the incidence of electrons. The device further comprises a displacing member (11) for displacing the liquid metal through an impingement position (55) where the electrons emitted by the source impinge upon the liquid metal. As a result of the flow of liquid metal through the impingement position the heat, which is generated in the impingement position as a result of the incidence of the electrons upon the liquid metal, is transported away from the impingement position. According to the invention, the displacing member (11) has a contact surface (61), which is in contact with the liquid metal in the impingement position (55), and a driving member (31) for moving the contact surface in a direction which, in the impingement position, is substantially parallel to the contact surface.

Abstract: A filter arrangement for a recording/reproducing wherein an air filter is adapted to filter an air flow of ambient air present within the housing during operation of the device flowing over an information surface of a rotating information disc disposed adjacent to the information surface in parallel spaced relation thereto, a casing within the housing encasing an information surface of an information disc disposed on the disc driving arrangement and provided with an air inlet for air to be filtered and an air exhaust for filtered air.
