Abstract: A window transparent to electron rays is provided which includes a foil which is transparent to electron rays and an element for supporting a peripheral region of the foil in an operational state. The element is made from a material having a greater linear thermal expansion coefficient than the foil material. The window transparent includes an intermediate layer between the foil and a retaining element. The retaining element acts as a support element and consists of a material having a linear thermal expansion coefficient which is equal or similar to the linear thermal expansion coefficient of the foil material and smaller than the linear thermal expansion coefficient of the material of the retaining element over a processing temperature range. A method of manufacturing a window which is transparent to electrons and an X-ray device with a window transparent to electrons are also provided.

Abstract: The invention relates to a window transparent to electron rays comprising a foil (1; 101) which is transparent to electron rays and an element (2; 102) for supporting a peripheral region (1a, 1b) of the foil transparent to electron rays in the operational state, which element is made from a material having a greater linear thermal expansion coefficient than the foil material, with an intermediate layer (4; 104a, b) which is arranged between the foil (1; 101) and a retaining element (2; 102) acting as a support element and which consists of a material having a linear thermal expansion coefficient which is equal or similar to the linear thermal expansion coefficient of the foil material and smaller than the linear thermal expansion coefficient of the material of the retaining element, seen over the processing temperature range.

Abstract: In order to increase the ruggedness and the scattered radiation attenuation quality, a grid (3) with comb elements (12) which absorb electromagnetic radiation and are intended to form a grid is constructed, in such a manner that comb lamellae (11) extend transversely of an associated comb base surface which supports the comb lamellae (11).

Abstract: The invention relates to a patient support for diagnostic apparatus, notably for an MRI apparatus, comprising a stretcher on which a patient can be arranged so as to be introduced into the diagnostic zone of the apparatus, the support comprising a core of a fiber-reinforced epoxy resin with a coating provided thereon, the core being made of a fiberglass-reinforced synthetic material on an epoxy resin basis with an isotropic fiberglass structure wherethrough cavities extend in the longitudinal direction, which cavities are filled with a fiber glass fleece impregnated with epoxy resin, the upper side being provided with a fiber-reinforced coating on an epoxy resin basis with unidirectional fibers of a synthetic material of a high tensile strength.

Abstract: A linear motor for the high-speed reciprocating movement of a mass-possessing rotor slide component and particularly of a radiation filter, with parallel flat stator plates with permanent magnets which are fitted to the facing sides of the stator plates and set up a magnetic field across the air gap between them. Fitted to the slide is a coil which can be slid in the permanent magnetic field. The coil consists of an aluminium foil provided at its surface with an insulating layer, which foil is wound to form an air-cored coil, and the slide is supported on gas bearings which extend through the aluminium bridges between the stator plates. To avoid impacts during acceleration and braking linear motors working reciprocally are provided.

Abstract: The pressure chambers (2) for the ejection of the ink are recessed in a body (9) of an ink jet printer. The chambers (2) are covered by a metal diaphragm (1). The pressure chambers (2) and the associated narrow passages (4) are formed in the body (9) by depression. Subsequently, the metal diaphragm (1) is connected to the body (9) by energy beam welding. The energy beam (31) is moved along the edges of the pressure chambers (2) and of the narrow passages (4). An electron beam or a laser beam may be used as the energy beam (31).

Abstract: An X-ray source having a cathode rotatable relative to the anode and a motor for rotating the cathode to produce a corresponding rotation of the X-ray beam emitted by the source.
