Abstract: On fabrique un supraconducteur par l'intermédiaire d'étapes de combinaison d'une pluralité de couches de feuilles de métal, afin de constituer une structure composite. Les feuilles se composent de métaux de transition purs tels le niobium, le titane, le zirconium ou le vanadium, ou leurs alliages, à partir desquels on constitue des feuilles alternées. La structure composite obtenue subit une réduction mécanique suffisante, de manière que chaque feuille de métal de transition soit d'une épaisseur inférieure à 1000 Å. Au cours de la réduction, on soumet le composite à des températures suffisantess pendant des durées suffisantes, de manière que les couches de métal de transition subissent une réaction au moins partielle, afin de constituer un matériau supraconducteur ductile entre les couches de métal de transition. Quelques-unes des couches de métal de transition ne subissent pas une réaction suffisante et restent non supraconductrices. Ces couches non soumises à une réaction permettent un pinning de flux efficace à l'intérieur du composite, quand les couches sont réduites à leur dimension finale inférieure à 1000 Å. Dans d'autres modes de réalisation, on peut utiliser des poudres et des filaments à la place des couches initiales. On peut constituer des alliages supraconducteurs binaires ou ternaires.

Abstract: Un appareil optique sert notamment à mesurer la vitesse d'une surface en mouvement au moyen d'un faisceau de mesure émis par un laser. Le faisceau de mesure est décomposé en deux parties (22, 23), dirigé de manière convergente par des prismes (24, 25) sur la surface en mouvement et reçu à nouveau avec un décalage des fréquences dû à l'effet Doppler. Un seul corps prismatique (24, 25) par faisceau partiel (22, 23) dirige chaque faisceau partiel (22, 23) vers l'extérieur, afin d'en accentuer la séparation, puis les dévie afin de les faire converger. Chaque prisme (24, 25) est de préférence fixé sur une plaque de verre (27) à faces planes et parallèles, de sorte que l'on puisse obtenir un ajustement très exact et durable.

Abstract: This invention relates to a multilayer, light-sensitive article having (a) a layer containing a photopolymerizable material containing a photopolymerization initiator and a polymerizable ethylenically unsaturated compound, and (b) a layer containing a thermoplastic resin. Light-sensitive articles have been employed in the preparation of overlay or surprint color proofing sheets, which are used to verify the accuracy, with respect to color, of separation films used in the preparation of printing plates. For example, a single-sheet, four-color proof (surprint) must duplicate with great accuracy the colored image and background to be achieved on a printing press using printing plates made with the same separation films. Whenever a layer of a photopolymerizable material that is a component of a proofing sheet construction comes into contact with a layer of resin, it is possible for one or more colored components of the layer of photopolymerizable material to migrate into the layer of resin and bring about a discoloration in that layer. This invention provides a light-sensitive article comprising (a) at least one layer of photopolymerizable material containing a polymerizable compound having at least one ethylenically unsaturated group, and a chromophore-substituted halomethyl-1,3,5-triazine photopolymerization initiator; (b) at least one layer of thermoplastic resin in contact with the layer of photopolymerizable material, said chromophore-substituted 1,3,5-triazine photopolymerization initiator capable of resisting migration to said layer of thermoplastic resin. The invention eliminates the problem of discoloration of the background resulting from excessive migration of the photoinitiator from the layer of photopolymerizable material to the contiguous layer of resin. The invention is especially useful in the preparation of surprint color proofs.

The capacitor element (104) is constituted of a first electrode (113) formed along an inner surface of the second trench, a dielectric layer (114) formed on the first electrode, and a second electrode (115) formed on the dielectric layer. The first electrode (113) is formed integrally with the semiconductor layer (107), thereby increasing the aperture ratio.
