Patent EP-0216750-A1 (EP)
Inventor: STENGL GERHARD DR
IPC: G03F1/74
Filed: 1986-09-10
Abstract: The invention concerns an ion beam apparatus, by means of which defects in a substrate can be recognized, and repaired under continuous control. For this purpose, the ion beam apparatus, in its beams path, after the ion source, is equipped with a mask exhibiting a preferrably circular hole and between ion source and mask with a controllable lens for the purpose of modification of the divergence angle under which the beam strikes the mask. The aperture of the mask is imaged upon the substrate. In this way the intensity of the ion beam may be varied for use in inspecting a substrate for defects and subsequently removing the detected defects.

Abstract: Une antenne omnidirectionnelle, plus particulièrement pour la réception de programmes de télévision dans la bande U.H.F. comprend quatre éléments de dipôle pliés (1-4) ayant chacun la forme d'une boucle autoportante ouverte en fil métallique (1A, 1B, 1C, 10) solidaire de parties jumelées de feeder (1E, 1F; 2E, 2F; 3E, 3F; 4E, 4F). Les boucles sont situées dans des plans parallèles à un axe central commun et sont décalées angulairement et régulièrement autour de cet axe, de sorte que les boucles se trouvent par paires, l'une en face de l'autre dans des plans parallèles. Le parties jumelées de feeder (1E, 1F; 2E, 2F; 3E, 3F; 4E, 4F) sont reliées en commun aux organes terminaux respectifs au niveau de l'axe central et chaque paire de parties de feeder de chaque boucle s'étend parallèlement aux autres dans une plan radial par rapport à l'axe central, ce qui permet une adaptation aisée de l'impédance de l'antenne à un câble connecteur.

Abstract: Une mémoire à accès sélectif possède un conducteur de rangée survolté au-delà du niveau de la tension d'alimentation pendant une partie initiale (30) d'un cycle de mémoire. La tension est ensuite verrouillée au niveau de l'alimentation pendant la partie centrale (31) du cycle, et éventuellement survoltée de nouveau pendant la partie de régénération (32). Cet agencement permet d'améliorer les performances et la fiabilité, notamment dans des mémoires utilisant des lignes de bits préchargées à un potentiel égal à la moitié du niveau de la tension d'alimentation.

Abstract: A scraper device to clean conveyor belts includes a bearing axle located below the conveyor belt for a blade holder having spring arms which can be mounted on the axle. The holder carries scraper blades at the end which in a preset angle of pitch are pressed against the conveyor belt. The spring arms comprise parallel guide rods of resilient material. The arms support the blade in a vertical position pressed against the lower segment of the belt. The angle of pitch is, in an advancing position of the scraper blades, maximally up to 10 DEG . In this way, with minimal wear and tear, optimum cleaning effects are achieved which, at the same time, show careful treatment of the belts.

Abstract: Device for forming thin films on a object to be printed (10) by printing. Said device is characterized by an intaglio formed into a cylinder, that is an intaglio roller (3) included therein. ink applied to said intaglio roller (3) is printed after having been temporarily transferred to a printing roller (4) or directly on the object to be printed (10) on a surface plate (11) positioned at a place for printing. In this manner, a thin film is formed on the object to be printed (10). As the intaglio roller (3) has a cylindrical body, the surface thereof can be easily and precisely finished by machining. Accordingly, if a large number of ink cells arranged in a predetermined pattern is given by machining directly to the surface of said intaglio roller (3), contact pressure on the surface of the printing roller (4) against the surface of the ink cells of the intaglio roller (3) or that on the surface of the object to be printed (10) tends to be uniform all over the surfaces, allowing the thickness of films to be printed on the object (10) to be uniform with high accuracy all over the surface.
