Abstract: Un panneau d'enregistrement d'images de rayonnement comprend une couche de phosphore non diffusant et stimulable, une couche-filtre qui absorbe fortement le rayonnement stimulant et transmet le rayonnement émis, et une couche permettant de diffuser le rayonnement. La couche-filtre absorbe le faisceau de rayonnement stimulant de façon à ce qu'une image enregistrée dans le panneau d'enregistrement ne soit pas rendue floue par des rayonnements stimulants dispersés au cours de la lecture, et que la couche diffusante augmente la capacité de fuite de la lumière émise à partir du panneau d'enregistrement.

Abstract: Un embrayage à ressort, conçu pour limiter le mouvement à vide pendant le débrayage, est décrit. L'embrayage à ressort comprend un arbre (29), un ressort à montage coaxial et enroulé en spirale (31) destiné à entrer en contact de friction avec l'arbre (29), et un dispositif (33) tel qu'un élément à languette, pour appliquer de manière sélective une force de desserrage à au moins une extrémité du ressort (33) pour le faire tourner par rapport à l'arbre (29). L'embrayage à ressort de cette invention comprend en outre un élément de pression (39) pour pousser le ressort (31) vers l'arbre (29) lorsque le ressort (31) est desserré par la rotation. Il en résulte qu'un mouvement radial du ressort (31), l'éloignant de l'arbre (29), est pratiquement évité. L'élément de pression (39) peut être retenu par un carter (35) monté de manière coaxiale autour de l'arbre (29) et peut être choisi à partir d'un moyeu (27) ou d'un ressort auxiliaire (39). L'élément de pression est de préférence situé à environ 90 degrées le long de la surface radiale externe de l'arbre à partir de l'extrémité du ressort où se situe l'élément à languette (33). Dans un autre mode de réalisation, un élément central est monté de manière coaxiale à l'intérieur de l'arbre de sorte que le ressort est situé entre l'arbre et l'élément central et l'élément de pression est retenu par celui-ci.

Abstract: On décrit un nouveau type d'enregistrement holographique dans des cristaux photoréfringents, appelé stockage orthogonal de données, et selon lequel des hologrammes en mode de réfléchissement et à contre-propagation sont multiplexés par répartition en longueurs d'ondes afin de former des réseaux de diffraction situés le long d'un axe commun. Il est démontré que cette configuration permet d'obtenir des améliorations sensibles dans la capacité de stockage de données par rapport à des systèmes antérieurs, et que des coefficients de couplage plus élevés peuvent être obtenus. En conséquence, l'on décrit non seulement un procédé de stockage de données mais également une large gamme d'autres dispositifs, y compris des filtres à sélectivité de longueur d'onde, des lentilles et des systèmes de correlation optique. En outre, des procédés d'écriture et de développement d'images métastables sont décrits, lesquels permettent d'améliorer sensiblement la puissance des réseaux qui sont développés en permanence dans le support photoréfringent. Ces procédés comprennent l'utilisation avantageuse de potentiels électriques et de caractéristiques photovoltaïques, avec des rapports réciproques différents au cours du développement.

Abstract: A servo control method capable of raising a band of speed loop stably and setting position loop gain to a satisfactory level. A torque command from a speed loop is sent through a filter whose transfer function has a numerator of the second degree and a denominator of the third degree. The filter has frequency characteristics shown in the figure in which at resonance frequency of an object to be controlled, phase lag in the band of speed loop is decreased and the gain in a high frequency region is decreased. This enables the gain of the speed loop to be increased stably without causing oscillation. Also, the high frequency disturbance can be removed.

Abstract: 2.1. In the digitisation of a video signal, it is frequently an object to convert the signal from a first scanning raster into a second scanning raster which has a fixed phase relationship to the line period. For this purpose, interpolation filters are used. It is the object to create a simple method for converting the scanning raster which does not require any D/A or A/D conversion for the conversion. 2.2. The phase relationship of samples with respect to the line synchronisation pulse (Z) is in each case determined in one line of the input signal at the beginning and at the end of the line (H) and the total number of samples of this line is determined, and these values are used for controlling the interpolation filter. 2.3. In particular for digital signal processing in a television receiver. <IMAGE>
