A radiation transducer has a luminophore layer applied on a substrate, and at least one anti-discoloration substance is applied on the luminophore layer. In a method to produce a radiation transducer a luminophore layer is applied on a substrate, and at least one anti-discoloration substance is applied on the luminophore layer after the application of the luminophore layer on the substrate.

A scintillator plate has a radiation-permeable substrate on which is applied a scintillator layer made of copper iodide that is formed from spicular crystals. The scintillator layer has an emission maximum in the red spectral range. The scintillator layer of the scintillator plate has a high emission power in the near-infrared range.

摘要:
The invention describes a dispenser (1) for automatically dispensing semi-fluid media, in particular toothpaste, from a tube with a mouthpiece, comprising a housing (2) with an orifice (3) and having at least one portion measuring unit (4) for the tube in the interior, a switch (6), a motor (20), a drive mechanism (5) and a control unit (7), whereby a brush is positioned in the orifice (3) in order to charge it with semi-fluid medium. In order to transport the brush automatically from the orifice (3) in the direction of the mouthpiece of the tube, at least one drive mechanism (5) is provided on a positioning mechanism (8), in particular a gear (33) with at least one driver (34).
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.
