Inventor: BANES ALBERT J
IPC: C12N5/071
Filed: 1988-05-03
Abstract: La présente invention décrit une composition à base de polyorganosiloxane recouverte d'une surface biocompatible. La surface biocompatible résulte de la dérivation ou de l'amination de la surface destinée à venir en contact avec les cellules. Plus particulièrement, la présente invention se rapporte à une composition à base de polyorganosiloxane dans laquelle la surface est soit traitée avec une amine primaire et éventuellement avec un peptide, soit copolymérisée avec du silane ou du siloxane contenant une amine primaire. Le polyorganosiloxane aminé est utile en tant que substrat de culture de cellules ou dans une variété d'applications relevant du domaine des organes artificiels, tels que greffes de seins, vaisseaux sanguins synthétiques, articulations, tendons, et valves cardiaques. Un appareil à vide destiné à être utilisé avec des plaques de culture de cellules spécialisées (10) contenant ladite composition à base de polyorganosiloxane et à surface biocompatible est également décrit.

Abstract: Un commutateur comprend une chambre de décharge à gaz, dans laquelle sont agencées deux électrodes, c'est-à-dire une cathode (11) et une anode (12), mutuellement espacées (d) l'une de l'autre et séparées par une paroi (9a) électriquement isolante en un matériau céramique ou en verre. La cathode (11) est pourvue d'un orifice (5) et les électrodes (11, 12) sont reliées par une liaison ou fusion étanche céramique-métal avec la paroi isolante (9a). Dans la chambre de décharge à gaz se trouve un gaz ionisable de remplissage à basse pression soumis à une pression p de sorte que l'allumage d'une décharge de gaz entre les électrodes (11, 12), se fait à une tension située sur la branche gauche et descendante de la courbe de Paschen. Dans le cas d'au moins une des deux électrodes (11, 12), les lignes de connexion (4), au niveau desquelles l'électrode correspondante (11, 12), le gaz et la paroi (9a) se touchent, présentent un écart minimum par rapport à l'électrode opposée (12, 11) supérieur à l'écart (d), à condition que l'électrode en question (11, 12) soit séparée de la paroi (9a) par une fente (3) dont la largeur est inférieure à (d).

Title: Appareil et procedes pour localiser les bords et les limites d'un document dans des lignes de balayage video
Inventor: MORTON ROGER ROY ADAMS
IPC: G06T7/60
Filed: 1988-07-05
Abstract: Sont décrits un appareil assorti de procédés d'utilisation, pour localiser des bords contenus à l'intérieur de chaque ligne de balayage d'une image vidéo balayée et également pour localiser des limites horizontales (bords d'attaque et de fuite) d'une portion d'un document contenue à l'intérieur de la ligne de balayage. Plus précisément, cet appareil fournit tout d'abord une valeur de fond représentative d'une densité de fond dans une image balayée et associée à une valeur de pixel d'entrée. Si cette valeur de fond excède une première valeur de référence, un premier signal est produit. Si la valeur de pixel d'entrée excède une deuxième valeur de référence, un deuxième signal est produit. Une transition de bord est d'abord détectée sur la base d'une combinaison logique prédéfinie des premier et deuxième signaux. Si une telle transition a été détectée, telle qu'un bord d'attaque ou de fuite soit dans les valeurs de pixel d'entrée soit dans la densité de fond, un circuit de commande, mis en oeuvre à titre d'exemple au moyen d'un circuit logique à réseau programmé et de divers compteurs, détermine si la transition de bord est associée à un bord d'attaque ou de fuite correct, c'est-à-dire si la transition elle-même est suivie d'un nombre pédéterminé de valeurs de pixel similaires. Si un bord d'attaque ou de fuite correct est détecté, le circuit de commande produit alors des signaux appropriés pour mémoriser comme bord d'attaque ou de fuite l'adresse de pixel horizontal de la valeur de pixel d'entrée. En outre, après détermination de tous les bords d'attaque et de fuite pour une ligne en cours de balayage, la paire de bords d'attaque/fuite présentant le plus large espacement est sélectionnée comme constituant les bords d'attaque et de fuite indiqués (limites horizontales) d'une portion d'un document exploré située à l'intérieur de la ligne en cours de balayage.

Inventor: ISHII TAKAHITO
IPC: H05B3/14
Filed: 1989-05-31
Abstract: The present invention provides a temperature self-­controlling heating composition containing crystalline resins, elastomers and electrically conductive particles, and additional material for giving an affinity to the resins and the elastomers if the both are not compatible, in which the electrically conductive particles are stably dispersed in the medium of the resin and the elastomer, and the agglomeration of the dispersed particles can be prevented, even if the temperature exceeds the melting point of the crystalline resine, because the apparent viscosity of the resin is not dropped so much by the net work structure of the elastomers, so that the electrical resistance does not drop down even in such a high temperature.

Abstract: The invention relates to a digital information transmission network between several stations, comprising a transmission medium (MT) passing through the stations (Si), each of which possesses an interface with the said medium (MT). According to a general definition of the invention, the interfaces are provided with a communication protocol of the CSMA/CD type. At least one of the stations (Si) acts as master (SM), the others being slaves (SEi). In current mode, the interfaces of the slave stations (SEi) have the right to transmit only in response to a personal request coming from the master station (SM), this eliminating any risk of collision. Some at least of the slave stations, termed freed, have the right however to transmit on their initiative, in an exceptional manner. In the event of collision, on such an exceptional transmission, this collision is resolved by the said CSMA/CD protocol. <IMAGE>

Abstract: A power steering apparatus wherein, when action of a hydraulic actuator of a source for steering assisting power is converted into steering motion, the steering momentum obtained in response to a specified magnitude of operation of the hydraulic actuator is larger at the central side of a rotation range of a steering wheel than at the end side thereof. The steering assisting power becomes larger as the steering angle becomes larger. As a result, when the steering wheel is largely operated, a burden of labor for steering is largely reduced without expecting an increase in capacity of the hydraulic actuator.

The apparatus (1) has a shaftlike reaction chamber (6) widening in upward direction and divided into compartments (6a, 6b, 6c) by means of horizontal grids (7). The process is performed by introducing a particulate solid of about 0.5 to 5 million meters particle size into the reaction chamber and passing a gas stream in upward direction through that chamber at an output sufficient to keep the particles in floating condition. A floating bed of solid particles will be formed in the reactior then and excellent solid-gas contact suitable for effecting chemical and physical reactions is provided hereby. A special embodiment relates to the removal of nitrogen oxides from flue gases with the aid of a particulate catalyst.
