摘要： Support device (53) provided with a first part (69) and a second part (71) which is supported relative to the first part by means of a gas spring (73) having a pressure chamber (75). A gas supply (117), which compensates for gas leakage from the pressure chamber (75) during operation, is connected to an intermediate space (119) which is in communication with the pressure chamber (75) via a pneumatic restriction (121). The gas pressure present in the intermediate space (119) is held as constant as possible during operation by means of a control loop (123), to prevent transmission of pressure fluctuations which are present in the gas supply (117) to the pressure chamber (75) as much as possible. Such pressure fluctuations are undesirable in the pressure chamber because they cause mechanical vibrations in the second part of the support device and the device to be supported. The support device is used in a lithographic device for the support of a frame (39) with respect to a base (37), the frame (39) supporting a focusing unit (5).

摘要： The transfer gate between the master section and the slave section in a flip-flop circuit includes a circuit for reducing the sensitivity to slow clock edges and clock skew. This is accomplished by prolonging the transfer time for data from the master to the salve section of the flip-flop circuit.

摘要： A lithotripsy workstation, comprises a patient supporting device (1), a shockwave source (4) for generating shockwaves which are focused onto a point (focus) (6) fixed in space, an X-ray source (10) which irradiates the focus (6) from at least two defined positions, and an image detector (12) which detects the X-ray image produced by the X-ray source (10). The cost and the weight of the workstation can be reduced in that a marker (16) which can be displayed in the X-ray image is secured to the X-ray source (10), which marker is situated, at least in the two positions, on the connecting line between the focal spot (11) of the X-ray source (10) and the focus (6).

摘要： A semiconductor device is formed by a semiconductor body (1) having a substrate (2) on which is provided a channel-defining region (10) extending between input and output regions (20) and (21). The channel-defining region (10) has a channel layer (11) forming a heterojunction (12) with at least one barrier layer (13) to form within the channel layer (11) a two-dimensional free charge carrier gas (14) of one conductivity type for providing a conduction channel (14) controllable by a gate electrode (25). A potential well region (30) is provided between the substrate (2) and the channel-defining region (10). The potential well region (30) has at least one potential well-defining layer (31) forming heterojunctions (32) with adjacent barrier layers (33) to define a potential well which is empty of free charge carriers of the one conductivity type when no voltage is applied between the input and output regions (20 and 21) and which is sufficiently deep and wide to trap hot charge carriers of the one conductivity type which are emitted from the channel-defining region (10) towards the substrate (1) when a high lateral electrical field exists in the channel-defining region (10), thereby constraining the hot charge carriers near to the gate electrode and enabling an improved output impedance when the device is an FET.

摘要： A semiconductor body has a surface structure (10) with an insulating layer (11) through which is formed an opening (12) defining a side wall (13) of insulating material bounding an exposed surface area (14a) of a region (14). An activating layer (15) is provided on the exposed surface area (14a) and the side wall (13) of the opening (12), and electrically conductive material deposited on the activating layer (15) to form an electrically conductive region (16) in the opening (12). The activating layer is provided so that the material (15a) on the sidewall (13) has different composition from the material (15b) on the exposed surface area (14a) and is selectively etched to remove the material (15a) from the sidewall (13) of the opening (12) leaving only the activating layer portion (15b) on the surface area (14a) of the underlying region so that little or no deposition of the electrically conductive material occurs on the opening sidewall (13), thereby inhibiting sideways growth of the electrically conductive material and thus avoiding or at least reducing the possibility of voids being formed in the electrically conductive region.

摘要： A groove is formed in a substrate layer by ion etching. The substrate layer comprises a top layer having an etch rate S1 and a bottom layer having a different etch rate S2, in which first, grooves are formed having an initial depth which differs from the desired depth, after which the etching process is carried out without using a mask until the desired depth of the groove is attained.

摘要： Contours are extracted from corresponding features the left ventricular blood pool-endocardium interfaces, of a plurality of images collected as a multi-phase multi-slice cardiac Magnetic Resonance Imaging (MRI) study which are accessible by a computer in response to user input to the computer of a seed contour identifying the contour feature to be extracted in an initial image at a middle slice position and a predetermined phase position, namely end of diastole. From this as the only contour inputted by the user, contours are extracted from each image by a sequence of automatic propagation of determinations of extracted, or final contours by forming from a final contour for an image, a seed contour for a not yet processed image which immediately adjoins in slice or phase position. For each image use is made of a seed-to-final propagation function in the form of an energy minimizing active contour function which has internal energy due to settable resistances to stretching and bending and image derived energy related to the gradient of the image. The final contour developed in the initial image is passed as a provisional contour to images which immediately adjoin in phase position where they are further propagated by an in-phase provisional-to-seed propagation function and are passed to images which immediately adjoin in slice position, where they are further propagated by an in-slice provisional-to-seed propagation function. After extraction of the contours, and possible automatic post-processing for correction thereof, these contours are used by a computational or visualization application, such as the computation of an ejection fraction.

摘要： In an infrared detector device for viewing an object or scene at more than one wavelength, the detector elements (10 and 20) are optimized to have appropriately different infrared responses by being formed in accordance with the invention in different levels (1 and 2) of different material on a substrate (3). Infrared concentrators (55) such as immersion lenses, light-pipes and/or reflectors collect incident radiation (50) over an area larger than the active portion of the associated detector element (10 and/or 20) and concentrate the radiation (50) onto the active portions. The arrangement adopted in accordance with the invention provides adequate space for at least one connection (15) of each upper-level detector element (10) to extend to the substrate (3) through an area of the lower level (2) which is located between the lower-level active portions on which the radiation (50) is concentrated by the associated concentrators (55). This upper-level connection (15) may extend via an island (28) separated from the active portions ( 22,23) of the lower level (2) by a gap (40), or it may extend on a side-wall of the lower-level detector element (20) when this side-wall is insulated or separated by a p-n junction from the active portions of the detector element (20). The different-response elements (10 and 20) may be arranged one above the other or one between the others when viewed in plan view.
