    摘要： An X-ray diagnostic apparatus has a luminescent storage screen for the latent storage of an X-ray image, an X-ray exposure apparatus for producing an X-ray beam, a readout apparatus system with which the storage luminescent screen is excited to luminescence by scanning with a source of radiation, a detector for the acquisition of the light emitted by the storage luminescent screen, and an image playback system. For the scanning, the storage luminescent screen is guided through an opening of a rectangular supporting structure and is held in the scanning region by air bearings attached to the supporting structure on both sides of the opening. A line-shaped source of stimulation radiation and a line-shaped light detector are mounted to the supporting structure.

    摘要： A fluorescent X-ray emitting source has an unfocused, omni-directionally radiating electron source and an anode target for the generation of X-ray bremsstrahlung, which releases mono-energetic X-rays in a fluorescent target. The electron source and the fluorescent target are arranged in a vacuum housing with an X-ray exit window. The housing has an interior wall surface forming the anode target and the fluorescent target is aligned with the X-ray exit window.

    摘要： A direct-heated flat emitter for generating a homogenous electron beam, particularly for x-ray tubes, has two terminal lugs for the heating current supply formed at the edge of the perimeter of the emission surface and the emission surface is subdivided into interconnects by slits. The slits have a width no less than 10 .mu.m and no greater than 1% of the length of a diagonal of the smallest rectangle which can circumscribe the emission surface.

    摘要： A linear compressor has a rigid frame (11, 12, 13), on which an oscillating body (16) is held via at least one spring (9) so as to be able to effect reciprocating motion and at least one electromagnet (14, 15) is mounted for driving the reciprocating motion of the oscillating body (16), and having a pump chamber (13) forming part of the frame, in which pump chamber a piston, connected to the oscillating body (16), may effect reciprocating motion. The frame (11, 12, 13) is connected in an oscillatory manner to a fixing member (1) for fixing the linear compressor to a support by a diaphragm spring (5, 7, 9) oriented transversely of the direction of movement of the oscillating body.
