摘要： An electromechanical displacement device (81) provided with a holder (90), an element (45) displaceable relative to the holder (90), and an actuator (83) connected to the holder (90) by which the element (45) can be displaced relative to the holder (90). The actuator (83) is provided with at least a first and a second clamping member (B, A) which can be clamped alternately against the element (45) under a mechanical pretensioning force F.sub.k, at least one clamping member (A) being provided with at least one piezoelectric, electrostrictive or magnetostrictive clamping element (61). The actuator (83) is further provided with a piezoelectric, electrostrictive or magnetostrictive transport element (69', 69") by which the distance between the clamping members (A, B) can be changed. When the first clamping member (B) is clamped against the element (45) under the mechanical pretensioning force F.sub.k while the second clamping member (A) is disengaged therefrom, activation of the clamping element (61) transfers the mechanical pretensioning force F.sub.k to the second clamping member (A), so that the second clamping member (A) is clamped against the element (45) under the mechanical pretensioning force F.sub.k, while the first clamping member (B) is disengaged therefrom.

End contacts of the electrodes consist of a thin sprayed-metal layer and a U-shaped cap which engages the capacitor in a clamping manner. The sprayed-metal layer and the cap can contact each other electrically via a solder layer. Preferably, the sprayed-metal layer is impregnated with a thermocuring synthetic resin and the synthetic resin is removed from a part of the sprayed-metal layer. The capacitor preferably comprises coating layers which are cemented to the multilayer by means of an adhesive layer.

摘要： The invention relates to an X-ray apparatus which includes an adjustable X-ray filter. In order to adjust an intensity profile of the X-ray beam, an X-ray absorbing liquid is transported to filter elements of the X-ray filter. Such transport is susceptible to gravitational forces which lead to an irregular hydrostatic pressure distribution in the X-ray filter. In order to reduce the effects of the gravitational forces on the transport of the X-ray absorbing liquid, the duct connecting the filter elements to the reservoir is subdivided into sub-ducts and the reservoir is subdivided into chambers, each chamber being connected to at least one sub-duct. The X-ray apparatus also includes means for keeping the sub-ducts aligned with a horizontal plane.
