Abstract: Fabric covered V-belts are produced which have a minimum co-efficient of friction on the outer surface (25). The cover fabric (22) is coated with elastomeric material on only a first surface (24). The elastomeric coating material does not penetrate the interstices of the fabric, and thus the second surface (25) of the fabric (opposite the first surface) is substantially devoid of elastomeric material. This is accomplished by applying the elastomeric coating material with a high viscosity (e.g. 40,000 cps-100,000 cps). The second surface of the fabric becomes the outer surface of the covered V-belt after the fabric is wrapped around the elastomeric material body (27) of the V-belt. During use, the outer surface fabric becomes slick, and has a small coefficient of friction, and thereby minimizes belt operating tension.

Abstract: Le moteur décrit comprend un logement (5) et plusieurs strates de stator parallèles (4) montées sur la paroi intérieure du logement entourant le rotor (3). Le stator (4) comprend plusieurs enroulements (28) enroulés autour des pôles (26) du stator. Chaque enroulement ou groupe d'enroulements connectés en série entre eux sont en outre connectés en série à un réseau de thermistors (29). Le thermistor (30) est de préférence placé sur une carte de circuits imprimés (36) montée adjacente aux enroulements (28), le thermistor (30) étant inséré dans un espace directement adjacent aux enroulements (28) du stator ou entre des enroulements adjacents (28) du stator, de façon à permettre au thermistor (30) de réagir avec précision à la température d'activation effective des enroulements (28). Lors d'accroissements de température, la résistance du thermistor à coefficient de température négatif (30) décroît, ce qui abaisse la résistance du circuit du moteur et maintient la constante de temps L/R du système. L'effet opposé se produit lors d'une baisse de température. Pour compenser le fait que des thermistors qui reflètent avec précision les changements de résistance du fil utilisé pour enrouler les enroulements (28) avec des changements de température ne sont pas disponibles, un résisteur (32) est connecté par fil métallique en parallèle avec le thermistor (30), le résisteur (32) ayant une valeur choisie de façon à modifier la résistance totale représentée par le réseau de thermistors (29) connectés aux enroulements (28), de sorte que la compensation s'effectue avec précision dans une large plage de changements de température et de conception du moteur. Le résisteur de shuntage (32) permet une flexibilité dans la conception du moteur, dès lors qu'il peut comporter n'importe quelle valeur sélectionnée allant de zéro à l'infini pour compenser les variations dans la conception du moteur.

Abstract: Générateur d'ondes en triangle (10) programmable et produisant des ondes en triangle, indépendantes de la fréquence et d'amplitude variable, sur une largeur de bande à large fréquence tout en n'utilisant qu'une source de puissance à basse tension. Ledit générateur d'ondes en triangle (10) comprend une source de signaux d'entrée d'ondes rectangulaires (12) et une source de signaux de tensions de référence (14). Un premier amplificateur (16) amplifie les signaux d'entrée d'ondes rectangulaires et les couple, par le biais d'un transformateur (34), à un intégrateur (36, 40) qui, en réponse, produit des signaux de sortie d'ondes en triangle. Un deuxième amplificateur (18) est relié au signal d'ondes en triangle ainsi qu'à la source de courant d'ondes rectangulaires couplée au transformateur pour fournir un amorçage. Un troisième amplificateur (20) échantillonne les signaux de sortie d'ondes en triangle, les compare avec les signaux de tensions de référence et produit, en réponse, des signaux d'erreur de sortie, auxquels répond un circuit (22) en fournissant des signaux de tension de polarisation au premier amplificateur (16) qui commande l'amplitude des signaux de sortie d'ondes rectangulaires en fonction de l'amplitude des signaux de tensions de référence. Les ondes en triangle sont produites de telle sorte que leur amplitude est proportionnelle à l'amplitude des signaux de tension de référence, mais indépendante de la fréquence des signaux d'entrée d'ondes rectangulaires. Ledit générateur d'ondes en triangle (10) produit une onde ayant une amplitude crête-à-crête de 20 volts à des fréquences supérieures à 300 KHz, en n'utilisant qu'une source de puissance conventionelle de U 15 volts. On décrit également un mode de réalisation où le générateur a une fréquence fixe et est non programmable, ainsi qu'un procédé permettant de produire des signaux d'ondes en triangle.

Abstract: Procédés de fabrication de lignes métalliques d'interconnexion dans un circuit intégré. En général, un procédé comporte la déposition d'une couche métallique sur une couche d'oxyde inter-diélectrique. La couche métallique est dessinée et gravée afin de former des lignes d'interconnexion métalliques par dessus la couche d'oxyde. Du tungstène est déposé sélectivement sur la couche gravée afin de compléter les lignes d'interconnexion métalliques. En outre, selon un deuxième procédé, une couche de tungstène peut être déposée avant la couche métallique entièrement enrobée de tungstène. En outre, du tungstène sélectif est employé à réparer des lignes métalliques cassées dans un circuit intégré préfabriqué. Le tungstène sélectif est déposé au moyen d'un procédé de dépôt à vapeur chimique et est déposé sur des lignes métalliques du deuxième niveau (au plus haut) qui sont masquées et gravées et qui sont formées dans le circuit intégré. Le procédé de dépôt sélectif de tungstène comporte l'exposition des lignes d'interconnexion métalliques à un mélange de SiH4 à un taux d'entre 3-10 centimètres cubes normaux par minute, de WF6 à un taux d'entre 3-25 centimètres cubes normaux par minute, et d'H2 à un taux d'entre 25-100 centimètres cubes normaux par minute. Ensuite les lignes d'interconnexion métalliques exposées sont traitées à une pression d'entre 50-200 mTorr, à une température d'entre 250-300 degrés Celsius, et un taux de dépôt d'entre 2000-10000 Angstroms par minute afin de former les lignes métalliques entièrement interconnectées. Le présent procédé améliore les rendements de circuits intégrés métalliques à plusieurs niveaux et maximise l'usage des grilles. Le dépôt de tungstène sélectif augmente les rendements de circuits intégrés, et le recouvrement de lignes métalliques en aluminium par de tungstène, par exemple, permet une interconnexion plus résistante à l'électromigration.
