Abstract: Technique, utile en particulier dans un système d'extraction d'images ou de gestion d'images, permettant de balayer une série d'images de microfilm se déplaçant dans un mécanisme de transport de film à une vitesse variable réglée par l'utilisateur, de manière à effectuer une mode opératoire de "recherche" efficace. Plus particulièrement, ladite technique fait appel à un balayage CCD fonctionnant à une fréquence d'horloge constante, par exemple, à sa fréquence maximale, tandis que des lignes individuelles disposées dans une image de microfilm se déplacent devant ledit balayeur à une fréquence supérieure au temps d'intégration de balayage. Le scanner produit, de cette manière, une série de lignes composites de données de pixels, chaque pixel d'une telle ligne représentant une moyenne d'un groupe correspondant d'espacements de lignes à résolution totale verticalement adjacentes et situées sur une zone de l'image de microfilm. Le nombre d'espacements de lignes dans ladite zone est égal à la valeur d'un rapport entre la vitesse du microfilm réglée par l'utilisateur et la vitesse du microfilm lorsqu'il est balayé à résolution totale. Chaque ligne composite de données est ensuite répétée un certain nombre de fois, ledit nombre étant, typiquement, égal au nombre d'espacements de lignes à résolution totale diposés dans la zone balayée associée à ceux-ci de manière à créer un groupe associé de lignes identiques de données de pixels. Ce groupe est à son tour, emmagasiné dans une série de lignes située dans une mémoire d'images. Les éléments du contenu total de ladite mémoire d'images sont sortis successivement et envoyés à un terminal d'affichage vidéo de manière à réaliser ensuite une visualisation à grandeur nature de l'image balayée.

When there are two cutting units (4,22) they may be positioned at a desired distance from each other and arranged for simultaneously cutting the opposite ends of a tread strip (3) arranged on a workbench (2,23). Each cutting unit (4,22) comprises a heated blade (5) which extends through a slit (11) in a transverse direction in the workbench (2,23) and moveable horizontally along the slit (11) itself in order to cut the tread strip (3) in a transverse sense. During the execution of the cut the tread strip (3) is held against the workbench (2,23) by means of a plate-like fastening element (14) which extends in a direction parallel to the slit (11) and very close to it. To the blade (5) there are connected a pressure roller (17) and a pressure sphere (18), one on each side of the cut, which operate in an elastic pushing relationship against the top of the tread strip (3) with the pressure sphere (18) moving between the tread strip (3) and the plate-like fastening element (14), to produce a pressure localized on the tread strip (3) itself in the vicinity of the cutting edge (5a) of the blade (5).

Abstract: Disclosed is a metal gasket 1 for a manifold produced by laminating a plurality of bead plates 2, 3 having bead portions 10, 11 which are bent at a predetermined radius of curvature R and by setting the ratio R/t of the radius of curvature R to the thickness t of the bead plates 2, 3 to the range of 7 to 15. Therefore, the radius of curvature R of the bent portions 12, 13, 14, 15 of the bead plates 2, 3 to the thickness can be made relatively great and the bent portions 12, 13, 14, 15 of the bead plates 2, 3 become smooth. As a result, when the metal gasket 1 is tightened between a cylinder head 19 and an exhaust manifold 20, the contact portions of the bead plates 2, 3 are expanded and the stress and face-to-face pressure occurring at the contact portions can be reduced. Accordingly, the stress acting on the bead plates 2, 3 can be made lower than a reference value, the increase of the face-to-face pressure can be restricted to within a predetermined range and the stress and face-to-face pressure of the bead portions 10, 11 forming a seal surface can be kept within suitable ranges. For these reasons, even if great thermal deformation occurs in the exhaust manifold 20 relative to the cylinder head 19, seal performance of the metal gasket 1 is not lowered.

Abstract: A quartz glass doped with rare earth element, aluminium and further fluorine, and endowed with various characteristics such as practicable luminescent properties, high amplification gain, achievement of wider band, size reduction of elements, fusibility and connectivity of quartz glasses with each other, and so forth. This glass is not accompanied with crystallization inherent in this type of doped quartz glass in the course of its producton, so that it is transparent of course and contains no residual bubbles. Since the production process comprises a combination of a technique for forming a porous glass with a method of solution impregnation, it is possible to produce readily a quartz glass doped with both rare earth element and aluminum, having high purity and excellent transparency, and being useful as an active optical element.

Abstract: Les caractéristiques principales du type de moteur proposé sont le mouvement alternatif harmonique des pistons et le mouvement coulissant libre des bielles associées. On a également prévu un équilibrage complet de ces moteurs, le balayage des moteurs harmoniques à combustion interne et à deux temps, l'étanchéification entre les parois du carter et des cylindres des moteurs harmoniques (lubrifiants interactifs dans le carter et sur la paroi du cylindre), et des configurations spéciales permettant la réalisation des moteurs proposés. On a abordé les problèmes que connaissent les moteurs thermiques en s'attaquant séparément à la fonction thermodynamique, en utilisant une fonction temporelle différente pour le volume de fluide moteur pendant le cycle, et à la fonction mécanique, en introduisant des mécanismes à inertie et friction réduites et à équilibrage complet. En général, les moteurs harmoniques se distinguent peu des moteurs traditionnels en ce qui concerne leur partie "supérieure" (c'est-à-dire la culasse de cylindre, le fond et le segment du piston, les cylindres, les systèmes d'admission et d'échappement, le système d'allumage, etc). Ils se distinguent au niveau du mécanisme cinématique, c'est-à-dire les pièces et la façon dont elles coopèrent pour transformer le mouvement alternatif des pistons en mouvement rotatif de l'arbre. Applications: moteurs thermiques alternatifs traditionnels.
