    摘要： The X-ray examination apparatus includes an X-ray source, an X-ray detector and an X-ray filter which is located between the X-ray source and the X-ray detector. The X-ray filter includes elements, notably capillary tubes, and the X-ray absorptivity of separate filter elements is adjustable by adjustment of a quantity of X-ray absorbing liquid in the respective filter elements. The quantity of X-ray absorbing liquid in the individual filter elements is adjusted by way of electric voltages applied to the individual filter elements. A control system is provided to apply the electric voltages selectively to the individual filter elements. The control system includes voltage lines and switching elements which electrically couple the filter elements to an electric voltage source. The filter elements are formed by spaces between corrugated plates or parallel plates provided with separating members, such as protrusions which extend transversely of the plates. The voltage lines are disposed on the plates. Preferably, the plates are formed from a stack of extendable wall foils and separating foils are provided partially between the wall foils so as to adapt the spacing of the voltage lines to the spacing of the switching elements.

    摘要： An X-ray examination apparatus of this invention comprises an X-ray source, an X-ray detector and an X-ray filter which is located between the X-ray source and the X-ray detector. The X-ray filter includes filter elements, notably capillary tubes, and the X-ray absorption of separate filter elements can be controlled by controlling a quantity of X-ray absorbing liquid in the respective filter elements. The quantity of X-ray absorbing liquid in the individual filter elements is controlled by way of electric voltages applied to the individual filter elements. The filter elements are formed as spaces between deformed foils which are arranged in a stack which is expanded in the direction transversely of the foils. Adjacent foils are locally attached to one another along seams. The stack is arranged between rigid plates and buffer elements are provided between the rigid plates and the stack. The buffer elements are contractable in the direction transversely to the direction of expansion of the stack. The shape of the cross-section of the capillary tubes is dependent on the ratio of the width of the seams to the spacing of the seams.

    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.

    摘要： A semiconductor device includes a transparent switching element (1) with two connection electrodes (2, 3) of a transparent material and an interposed transparent channel region (4) of a semiconductor material provided with a transparent gate electrode (5) of a conductive material, separated from the channel region (4) by a transparent insulating layer (6). The semiconductor material is a degenerate semiconductor material with a basic material having a bandgap (10) between conduction band (11) and valence band (12) of electrons greater than 2.5 eV and a mobility of charge carriers greater than 10 cm.sup.2 /Vs provided with dopant atoms which form a fixed impurity energy level (13) adjacent or in the valence band (12) or conduction band (11) of the basic material. The degenerate semiconductor material is transparent because the absorption of visible light is not possible owing to the great bandgap (10), while also no absorption of visible light takes place through the impurity energy levels (13). The device is capable of comparatively fast switching.
