Abstract: 1. Method for the determination of azimuth angle using a gyroscope (4) suitable for strap-down application, in which, in a computer-controlled and automatic manner, by means of a first measurement, the azimuth angle PSI between a gyroscope measurement axis and North is determined in an initial position, in a second measurement in a position rotated by 180 degrees around the axis of rotation of the gyroscope or spin axis, the azimuth angle PSI + 180 degrees between the gyroscope measurement axis and North is determined and a third measurement is carried out in the initial position corresponding to the first measurement, and subsequently, assuming and specifying a variation of the gyroscope measurement signals which is exponential with time, a weighted mean is formed between the measured values of the first and third measurements in a signal recording and processing unit in such a way that the mean values substantially correspond to the values in the time interval of the second measurement, characterized in that - acceleration forces acting on the gyroscope (4) are measured in two directions which are perpendicular to one another and approximately perpendicular to the axis of rotation of the gyroscope, - the mean value formation is applied in a similar manner to the measured values of the acceleration forces, and the averaged measured values are used to determine a horizon reference, and in that - the gyroscope information measured and obtained by corrected mean value formation is corrected on the basis of the horizon reference.

Abstract: In the process claimed substrates (17), placed in a boat (16), are heated in a furnace (12) at reduced pressure. The source, tetra-ethyl-ortho-silicate (TEOS), is provided and its usage metered as a liquid (2). Just before entering the furnace-tube (10) it is evaporated (9). The pressure in the tube is measured (14) and maintained by a pump (19). An additional flow of O2 may also be provided via an other inlet (15) to improve the stoechiometry of the SiOx-layer. The deposition rate is controlled pref. by the partial pressure of the source-material at a constant temp. between 700 and 750 deg. C., pref. 730 deg. C, over pressure-range of 70-700 microbar by adjusting the lqiuid flowrate to 0.1-1.0 cm3/min. Prefd. conditions are a liquid flow of 0.2 cm3/min. of TEOS and 20 cm3/min. of O2. The liquid TEOS-source may also contain liquid cpds. of certain pref. elements., e.g. triethylphosphite (TEP), triethylarsenide or trimethylborate (TMB). From this mixture a layer is then deposited at 130-700 microbar pressure, using a liquid flow rate of 0.2-1.7 cm3/min. and pref. including extra O2, pref. in excess of stoechiometric quantity. Pref. conditions for a glass layer with 2% P and 4% B are a flow rate of 0.7 cm3/min. of a liquid source containing 14.7 wt.% TEP, 12.6 wt.% TMB and the rest TEOS, with an additional flow of 100 cm3/min. of O2.

Abstract: An automatic activation apparatus for a differential pawl which is independent of intervention by an operator of a vehicle, the invention controls the energy supply to the actuator by means of a control logic with two signal inputs. The control logic is fed a wheel slip signal directly at one signal input, and via a break-delay timing element at its other signal input. The control logic is thereby designed so that, by the excitation of both signal inputs, it switches into a standby position and then into its active position only upon the excitation of its signal input connected with the timing element.

Abstract: A sealing device particularly suitable for sealing pistons of working cylinders and for sealing two machine components which can slide against one another is disclosed. A conventional sealing element consisting of low-friction, but not very elastic material, such as PTFE plastic material, and resting on an elastic support, is used. The cross-section of the sealing element in a direction of the sliding motion is U-shaped and encircles the support. The dimensions of the support and the sealing element are determined such that the support exerts prestress forces on the sealing element which try to bend the rim areas of the sealing element outward against the sliding surface for the sealing element. Consequently, an additional force component, directed toward the sliding surface, results for the pressure force which is exerted on the sealing element by the support and functions as a sealing force.

Abstract: A static current source has at least two MOS transistors switched in cascade, branched across a MOS transistor current source. There are at least two branches having at least one current source transistor (T12) in common.  Each branch has at least one switching transistor (T13,T14) operating at the same time as a current source transistor. The branch transistors (T13,T14) are driven at the saturation level.  The gate voltages (VGS13,VGS14) of the transistors are switched between two constant voltages so that one of the transistors conducts.  The voltage is held constant independently of the drain voltages at the common junction of these transistor representing their source node.  The disadvantageous discharge of the parasitic capacitive (Cp) is avoided.

Abstract: The logic device comprises a programmable array responsive to to signals applied to the external terminals of the device for generating a number of logic signals. A number of programmable output cells each receive logic signals which are stored and generate a signal in return at predetermined input/output ports. A number of storage cells each store predetermined logic signals and generate a signal in return. A counter stores a count value which is selectably incremented or decremented and generates counting signals indicative of the value. A device receives and counts signals and logic signals for storing the count value in a last-in, first-out stack for removing the last-in contents of the stack. The counter also receives signals generated by the stack.

Abstract: A digital image processing system for converting continuous tone pixel values representing an image into halftone or dithered pixel values, with the dithered pixel values representing each pixel having fewer bits than are used to represent each pixel in the continuous tone image. The continuous tone pixel for a line of pixels is loaded into an input buffer circuit having a plurality of storage locations, with each location storing the continuous-tone values for one pixel. Iteratively, the pixel value from each location is modified by a perturbed weighted error value, and then quantized to form the output halftone or dithered pixel value. An error value is then determined which is used in processing of subsequent continuous tone pixel values. The processing of the continuous tone pixel values procedes in a serpentine manner over the image, that is, processing of adjacent lines of the continuous tone pixel data proceeds in opposite directions.
