Patent EP-0484263-A1 (EP)
Inventor: BRODSKY STEPHEN BRUCE
IPC: H01L21/331
Filed: 1991-10-10
Abstract: A contact is provided in a self-aligned manner to a doped region a semiconductor substrate by first forming a layer (16) of a transition metal-boride compound over a selected region (20) on the substrate (10). A layer (18) of a transition metal-nitride compound is formed over the layer (16) of transition metal-boride compound, and the structure is heated to drive dopant from the layer of transition metal-boride compound into the substrate. Finally, the transition metal-boride/transition metal nitride layers are patterned to leave the desired contact.

Title: Thermally-reversible isocyanate polymers
Inventor: MARKLE RICHARD A
IPC: C08G18/32
Filed: 1991-02-04
Abstract: Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. High-performance characteristics are incorporated into the polymer by using polyimide, aromatic polycarbonate, aromatic polyester, polyphenylene sulfide, and poly(parabanic acid) oligomers. Low-temperature flexibility and toughness are imparted to the polymers by using prepolymers such as polycaprolactone diols, polytetramethylene ether glycols and polyaliphatic carbonate diols. Ionic bonding and liquid-crystal functionality may also be incorporated into the compositions. The compositions are useful as hot-melt adhesives, coatings, and moldings and in injection reaction molding applications and composite and laminate fabrication.

Abstract: Constituant catalyseur solide et procédé de fabrication de ce produit. On décrit un système de catalyseur dans lequel le constituant catalyseur solide est incorporé, et un procédé servant à polymériser une ou plusieurs 1-oléfines au moyen de ce système. On prépare le constituant catalyseur en mettant en contact, en présence d'un hydrocarbure liquide inerte, de la silice, un organomagnésien soluble, un adhésif de magnésium SiCl4, un alcool, TiCl4, et un composé de diester, et on effectue ensuite une extraction avec un liquide d'extraction contenant du TiCl4. Ce système de catalyseur inventif permet de contrôler facilement le poids moléculaire du produit en surveillant la concentration d'hydrogène dans le réacteur, et permet de produire en grandes quantités des polymères d'indice de fusion et d'indice de fluidité élevés.

Abstract: On ajoute une solution alcaline aqueuse (10, 14A) à une pâte écrue (8) à faible consistance afin d'assurer la répartition sensiblement uniforme dans la pâte d'une première quantité de matière alcaline. Ensuite, on augmente la consistance de la pâte jusqu'à ce qu'elle dépasse environ 18 % (12), puis l'on traite la pâte à consistance élevée contenant la matière alcaline avec de l'oxygène (21) afin d'assurer la délignification (20). La quantité globale de matière alcaline ajoutée à la pâte est comprise entre 0,8 et 7 % du poids de la pâte absolument sèche. On forme ensuite des pâtes à résistance élevée et à faible teneur en lignine que l'on peut blanchir au moyen de quantités réduites de produits chimiques jusqu'à ce qu'elles présentent un degré élevé de brillance.

Title: Regulation dynamique de la vitesse de codage, minimisant l'encombrement du trafic dans un reseau de commutation par paquets
Inventor: HLUCHYJ MICHAEL G
IPC: H04L12/56
Filed: 1991-07-17
Abstract: L'invention convient à un réseau de commutation par paquets qui transporte des données en rafales. Un mécanisme (18, 26) est accouplé à un noeud marginal (12) afin de coder des informations en rafales en un format numérique, soit à une première vitesse de codage soit à une seconde vitesse de codage inférieure à la première. Un mécanisme détecte une surcharge de trafic sur un ou plusieurs noeud(s) intermédiaire(s) transportant les informations en rafales. Un mécanisme réagissant par rapport au mécanisme détectant la surcharge permet à celui-ci de passer de la première vitesse à la seconde pendant qu'une surcharge de trafic est détectée. Ainsi, les besoins du réseau en réponse à la demande sont réduits et la surcharge amenuisée.

Title: Forming carbon dioxide in multi-phase molten bath.
Inventor: NAGEL CHRISTOPHER J
IPC: C01B32/50
Filed: 1991-07-23
Abstract: A method and a system for catalytically converting a hydrogen component in a hydrogen- and carbon-containing feed to dissolved hydrogen and for oxidizing the dissolved hydrogen to water is disclosed. Hydrogen- and carbon-containing feed, such as municipal garbage, low grade fuel oil and organic or inorganic sludge, is introduced to a molten bath system. The molten bath system includes first and second immiscible molten metal phases. Carbon and hydrogen component in the feed are converted to dissolved carbon and dissolved hydrogen, respectively. The dissolved carbon is oxidized in the first molten metal phase to carbon monoxide, which then migrates out of the first molten metal phase. As dissolved hydrogen accumulates in the first molten metal phase, it nucleates and migrates to the second molten metal phase, where it is oxidized and forms water vapor.

Abstract: On décrit un procédé de préparation d'un alliage métallique eutectique ou hyper-eutectique raffiné ou renforcé et qui consiste à: faire fondre l'alliage métallique eutectique ou hyper-eutectique, ajouter des particules d'un matériau réfractaire non métallique à la matrice métallique fondue, mélanger l'alliage métallique fondu et les particules du mßteriau réfractaire, et couler le mélange qui en résulte dans des conditions produisant la précipitation d'au moins une phase intermétallique de la matrice métallique fondue au cours de sa solidification, de sorte que les produits intermétalliques formés au cours de la solidification mouillent et englobent lesdites particules réfractaires. Les particules ajoutées peuvent être très petites et ne servir qu'à raffiner les produits intermétalliques de précipitation dans l'alliage, ou elles peuvent être plus grosses et servent de particules de renforcement dans un composite comprenant l'alliage. Les produits obtenus sont aussi nouveaux.

Abstract: The marker is comprised of a combined tip (8), a tip guard tube (6), a tip position fixing device (12), a movable tip holder (10) and other parts. The tip points either closed up or separated can be controlled as desired by the relative displacement of the movable tip holder (10) and the combined tips (8), thus the any color mingling among the tip points is prevented. To process the points as well as the tail end of a tip with specified length and shape in one single working step, a cutting device, specially designed, is used. Owing to a position fixing device (12) for mounting the combined tips the consistency and reliability of products may be secured and the percentage of qualified product and shelf life of product have been raised consequently saving of raw mmterials consumption, time, along with working steps have been obtained. In addition, the automation of processing line for the production of combined tips of this multicolor marker is facilitated.
