摘要： The invention relates to a magnetic bearing, wherein a first part (1, 20) is magnetically mounted in relation to a second part (3, 10) and the second part (3, 10) has a supraconductive material (2) of a second type containing an anisotropic crystal or several grains consisting thereof, wherein said crystal is anisotropic due to the fact that the supraconductive current is guided on the current carrying planes. According to the invention, the first part (1, 20) has a configuration consisting of magnets (1; 6, 7, 8; 11, 12, 13, 14; 30, 31, 32, 34; 50, 51, 52, 53) interacting with the supraconductive material (2), wherein the crystal itself or the crystal contained in the majority of the grains and the normal line or lines on the current carrying planes (a-b) are directed towards the first part (1, 20).

摘要： The invention concerns a video projection apparatus for displaying on a screen (7) a video image composed of pixels of a defined size, with at least one light source (1) for transmitting a light beam (2) having a predetermined beam profile in order to illuminate each pixel on the screen for a predetermined time interval. According to the invention, the beam profile of the light beam (2) is extended further than the defined size of the particular pixel to be illuminated, and the time interval is so short that the size can be perceived in the eye of an observer watching the video image such that it corresponds to the defined size of the pixel. A method in which a video image is composed from pixels on a screen (7) by directing onto the screen (7) a light beam (2) having a predetermined beam profile for illuminating each pixel of a defined size for a predetermined time interval is characterized in that a light beam (2) is used which has a beam profile which is extended further than the defined size of the particular pixel to be illuminated, and each pixel is illuminated for such a short time interval that the size is perceived in the eye of an observer watching the video image such that it corresponds to the defined size of this pixel.

摘要： In a video system for displaying a video image made up of pixels, the pixel colour and/or luminosity values are sequentially stored in an image storage (12) according to a set of parameters with predetermined values which include definition, image element number, line frequency and frame frequency. The stored video image may then be read by a display (16, 30, 32) according to a second set of parameters whose values are the same as or different from those of the first set of parameters. The display (16, 30, 32) has a single light source (16) that can be controlled depending on the pixel colour and/or luminosity values and whose light beam (26) can be projected by optics (30) onto a screen (32). The optics (30) include a scanning device (36) capable of projecting the light beam (26) onto the screen (32) on any desired spot within a predetermined image field having the appropriate size to display the video image. A scanning control (42) allows scanning of the light beam (26) according to the second set of parameters.

摘要： In a colour transformation process for transforming input-side reference stimuli (R, G, B) into picture-side reference stimuli (R', G', B') with a greater range of colour stimulus specifications than is given by the input-side reference stimuli (R, G, B), colour transformation is carried out in the following steps: conversion of the components of a colour vector of the input-side reference stimuli to give notional reference stimuli (R', G', B'), thereby altering the colour stimulus specification of the colour vector; and transformation of the converted components of the colour vector of the notional reference stimuli (R', G', B') into the picture-side reference stimuli (R', G', B') to produce picture-side components of the colour vector, the picture-side reference stimuli thus produced having the same colour tone and saturation as the colour stimulus specification produced by conversion in the notional reference stimulus system (R', G', B'). A colour video system for carrying out the process in question has a circuit (15) for converting the signals to the notional reference stimulus system (R', G', B'), and a matrix switch (14) for transforming the notional reference stimulus system into the picture-side reference stimulus system (R', G', B').

摘要： The invention relates to a device for displaying a video image, comprising at least a source (44, 44') emitting an intensity modulated light bundle (39, 39') and a deflection device (41, 42) to deflect the light bundle (39, 39'). The source (44, 44') emits two independent modulational light bundles (39, 39')in order to conduct angle-proportional line scanning of Np pixels at an angle αp and to carry out angle-proportional scanning of the light bundle (39, 39') of Nz lines of the video image at an angle αz. The first light bundle (39) is modulated with video information to illuminate a scan-controlled first pixel and the second light bundle is modulated with video information to illuminate a second pixel. The video information of the second pixel is staggered by mz lines of an image and mp pixels of a line in relation to the video information of the first pixel, the whole numbers being mz ≤ Nz and mp ≤ Np and mz and/or mp 0. An optical system (40) is provided which groups both light bundles (39, 39') in a common real or virtual point (54) located in front of or inside the deflection devices in the direction of light propagation. Both light bundles (39, 39') diverge on said point at a predetermined angle mz x αz/Nz in the direction of image scanning and mp x αp/Np in the direction of line scanning.

摘要： Device with a laser (10, 20, 30) for image reproduction. The laser (10,20,30) emits a laser beam (12, 22, 32) with a defined coherence length L for a given wavelength μ. The invention provides a first structure (44; 45; 52; 43; 67) which is placed in the path of the laser beam (12, 22, 32) enabling phase shifts to occur for the individual photons of the laser beam (12, 22, 32) according to a predetermined distribution. The average path resulting from the ratio between the average quadratic value of the phase shift caused by distribution and the sum of the wave vector k = 2 π/μ of the laser (10, 20, 30) is greater than the coherence length L multiplied by a factor 1/(12)1/2.

摘要： In a process for the transmission of a light beam for illuminating pixels in a video image, with the light beam being inserted into an optical fibre (6), with a certain divergence angle and beam diameter determined by the way it is generated and being launched by an optical system (4) used to bundle the transmitted light beam (15) leaving the optical fibre (6), it is proposed to adjust the divergence angle of the light beam (15) leaving the optical fibre (6) proportionally to the divergence angle given by the way it is generated, the proportionality factor being the ratio of the given beam diameter prior to the beam's insertion into the optical fibre (6) to the beam diameter of the light beam launched by the optical system. A video system for carrying out the process has an optical system (4) which is dimensioned accordingly.

摘要： The invention concerns a method of processing a video image with image points in m1 lines, the points in the l1-th line having an intensity I1(t, l1) which depends on a parameter t, in particular time, in order to generate a second video image with m2 lines. The invention calls for the intensity I2(t, l2) of each image point in the l2-th line of the second video image to be interpolated from the intensities of the image points of the first video image I1(t, l1), the intensity I2 being obtained from the equation: I2(t,l2)=Max[J(t,l2)+Δ;0] in which J represents values, discretized with respect to the lines, of changes in signal defined by the scan theorem and which includes an offset Δ for partial compensation of negative intensities of the discretized changes J in the signal, so that the interpolation is carried out with respect to the lines with A as a freely determined positive-value amplitude in accordance with the equation (1). The invention also concerns a device including circuit elements suitable for the generation of the second video image by the method proposed.
