Abstract: The device is intended especially for combat tanks. A collimator (7), permanently connected to the weapon (1), is used to produce a light beam emanating from an optical test target. The collimator (7) is arranged in front of the lens of the sighting device (6) in such a way that the light beam impinges on a position-sensitive, optoelectronic measuring sensor (8) arranged in the image plane in front of the eyepiece of the sighting device (6). The measuring sensor is connected via an electronic evaluating device (9) to an evaluating computer (10). A predetermined directing signal is generated by a program-control device (12) by means of a multifunction generator (13) and fed to the fire control system (4). The evaluating computer (10) is connected to the fire control system (4). In the evaluating computer (10), predetermined primary set values of the fire control and directing data are on the one hand compared with secondary set values determined by the fire control system and fed to the evaluating computer (10) and on the other hand with actual values concerning the position of the weapon (1), supplied by the measuring sensor (8). <IMAGE>

Abstract: A silicon substrate having a silicon dioxide bird's head is provided. A thermal oxide layer is grown on the exposed silicon surface. A layer, e.g., 4000 A°, of phosphogermanosilicate glass is deposited on the thermal oxide and on the silicon dioxide bird's head. The structure is heated to 950°C, causing a reflow of the glass which results in a planar surface. The thermal oxide and the phosphogermanosilicate glass are then wet etched at the same rate with a solution of hydrofluoric acid, ammonium fluoride, and deionized water. The wet etch is terminated when the exposed silicon surface is reached, resulting in a smooth surface as defined by the planar reflow surface. Other embodiments are disclosed.

Abstract: A video signal interpolation includes a frame interpolation filter (402) which generates from a video input signal (Y) by interpolation from corresponding elements of immediately preceding and following fields, a frame interpolated output signal tending to exhibit motion artefacts. A second filter (430) provides a line interpolated signal having picture elements spatially and temporally coincident with corresponding elements of the frame interpolated signal and having a suppressed vertical detail component. A third filter (440) attenuates the vertical detail component of the frame interpolated signal. An output circuit (461, 450) combines the signals of the three filters to provide a frame interpolated video output signal (Yi) in which the vertical resolution of the video input signal (Yd) is preserved and motion artefacts characteristic of frame interpolation are attenuated. The interpolator of the invention is particularly suitable for providing the required interpolated video signal in progressive scan display systems in which a delayed and time-compressed video signal derived from a video input signal is displayed line-by-line alternatingly with an interpolated video signal obtained by interpolation from the input signal.

Abstract: A process for manufacturing a semiconductor device eliminating a post-metalization heat treatment that results in fewer hillocks and improved ohmic contacts. Semiconductor devices having metalization are processed by maintaining the device at a first temperature below about 275°C subsequent to the deposition of the metalization layer and prior to the deposition of the topcoat silicon dioxide material. Then the layer of silicon dioxide is deposited at a second temperature greater than about 375°C. Preferably, double-level metalization devices are processed by maintaining the device at a first temperature below about 275°C subsequent to the deposition of the first layer of metal and prior to the deposition of the interlevel dielectric silicon dioxide. The interlevel dielectric layer of silicon dioxide is deposited at a second temperature greater than about 275°C and then the second layer of metalization is deposited. The topcoat layer of silicon dioxide is deposited at a third temperature greater than about 375°C.

Abstract: The method of making contour seams on material to be sewn starts from a sewing position in which the material to be sewn has been clamped in spread manner, before the sewing operation, by means of three gripping points provided along a contour line. The contour line is defined by the pattern of the cut and superimposed fabric edges of pieces of material to be sewn together. The gripping point closest to the sewing-machine is stationary, and the two other gripping points are each supported so as to be movable in a polar coordinate system. Initiation of the sewing operation is effected each time with simultaneous release of the material to be sewn in the stationary gripping point, and in at least part of the sewing operation the stitch chain is guided parallel to the contour line in opto-electronic control.
