Patent EP-0642587-A1 (EP)
Inventor: LOESCHE WALTER J
IPC: C12Q1/37
Filed: 1992-05-22
Abstract: Un dosage colorimétrique détecte la présence d'une activité protéolytique dans une éprouvette de plaque subgingivale, par exemple, avec une substance de test chromogène qui est hydrolysée par des enzymes proches de la trypsine, fabriquées par des bactéries parodontopathogènes présentes dans l'épouvette, pour libérer un chromophore. La libération du chromophore est associée à un changement de couleur visible et indique la présence d'une parodontolyse. Les résultats de ce dosage chromogène pour détecter une activité protéolytique sont fiables pour autant qu'il y ait dans l'épouvette au moins un nombre minimum de microorganismes, de l'ordre de 1.000.000 à 10.000.000. Le dosage colorimétrique de la présente invention indique si l'épouvette contient le nombre requis de microorganismes pour ne pas occasionner de résultats négatifs faux dus à la taille insuffisante de l'épouvette. Un marqueur non spécifique de l'activité enzymatique des microorganismes dans l'épouvette, par exemple, de la phosphatase ou de la peptidase, indique si la taille de l'épouvette est suffisante, par la libération d'un chromophore issu d'une substance de test chromogène non spécifique, en réponse à l'activité enzymatique non spécifique.

Abstract: L'invention concerne un procédé et un produit appliquant des concepts avancés d'une technique en Z dans le domaine des boîtiers électroniques à haute densité de composants. Pour des tranches de silicium classiques contenant des puces (20), on suit des modes opératoires de modification qui créent des puces CI (38) possédant des conducteurs métalliques de deuxième niveau (30) sur la surface supérieure de la couche de passivation (52) (qui couvre le silicium d'origine (48) et l'aluminium ou autre métallisation (44)). Le métal des conducteurs de deuxième niveau (30) est différent de celui de la métallisation dans les circuits intégrés et permet une meilleure conduction électrique. Les puces modifiées (38) sont séparées des tranches (20) et sont ensuite empilées pour former des dispositifs à circuits intégrés multicouches (60). Une pile comporte un ou plusieurs plans d'accès (64). Après superposition, et avant application de la métallisation sur le plan d'accès, une opération d'attaque chimique enlève tout aluminium (ou autre matériau) qui pourrait interférer avec la métallisation formée sur le plan d'accès. Des plots métalliques (92) sont formés en contact avec les cosses des conducteurs de deuxième niveau (30) sur les puces empilées. Les plots et les cosses sont formés de la même matière métallique afin d'optimiser le rendement de conduction des connexions T.

Abstract: Dans un moteur linéaire synchrone, un champ à ondes progressives généré dans des sections individuelles (SA, SB, SC) d'un stator allongé opposées à une partie d'excitation (EE) montée sur un véhicule coopère avec le champ généré par alimentation en courant continu de l'enroulement excitateur (EE), faisant avancer le véhicule. Le courant alternatif fourni à la section de stator afin de générer le champ à ondes progressives n'induit pratiquement pas de tension dans l'enroulement excitateur. Afin d'assurer une transmission d'énergie par induction, un courant alternatif de plus haute fréquence est superposé au courant alternatif disponible pour générer le champ à ondes progressives. Ce courant alternatif de plus haute fréquence génère une tension de haute fréquence dans l'enroulement excitateur qui peut être considéré comme constituant l'enroulement secondaire d'un transformateur qui comprend l'enroulement de stator et l'enroulement excitateur. Cette tension de haute fréquence peut être découplée par un redresseur passif ou actif de courant (GE). L'énergie ainsi générée est disponible pour des appareils auxiliaires situés dans le véhicule et/ou pour alimenter l'enroulement excitateur (EE) en courant continu.

Abstract: An electronic switch (10) is disclosed using a piezoelectric push button transducer (12) and an electronic switching circuit (14). The push button piezoelectric transducer (12) is connected with the switching circuit (14) with a polarity to provide a switching voltage in response to actuation of the push button switch (12) by finger pressure. The connection is such that the polarity of the voltage generated as a result of differential thermal expansion of the piezoelectric transducer (12) is opposite that produced by finger pressure on the push button switch (12) and does not produce false switching from fast temperature rise. In order to protect against false switching due to high temperature soak of the electronic switch (10), a thermistor is provided in the electronic switching circuit (14).

Abstract: A lubricating film of the invention is comprised of a chemically adsorbed monomolecular film, in which long-chain molecules are chemically bonded to at least one surface of a substrate via siloxane bonding, and layers of chemically adsorbed monomolecular film are formed on the surface of the previously formed chemically adsorbed monomolecular film after changing the groups at the end of chemical admolecules to monofunctional groups. The lubricating film has excellent endurance against sliding, with lubrication and anti-abrasion properties, and such properties of the film can be maintained for a long period. A chemically adsorbed monomolecular film can be formed on a substrate surface via covalent bonding (SiO-) by the dehydrochlorination reaction between active hydrogens on the substrate surface and the silane-based chemical adsorbent comprising dimethylsilyl groups. The substrate formed with the chemically adsorbed monomolecular film is then treated by an oxidation treatment, an alkaline treatment or an energy irradiation, thus changing the dimethylsilyl groups to the active hydrogen groups such as hydroxyl groups, imino groups or the like. The above-noted chemical adsorbent is contacted to the substrate surface, thus forming a chemically adsorbed multilayer film. Moreover, a long-chain hydrocarbon compound can be physically adsorbed to the surface of the chemically adsorbed multilayer film.

Abstract: The conventional roller bottle-like culturing vessel (1) for cell cultures forms a supply chamber and receives a nutrient medium in which there is arranged at least one production chamber accommodating the cell cultures, the production chamber being separated from the nutrient medium by a dialysis membrane (15) and having a gas inlet and outlet in the supply chamber. In order, starting from this known vessel, to design a culturing vessel for the generation of cell cultures with a high cell density, which is cheap to produce and simple to handle and which avoids the risk of infections it is proposed that the gas inlet and outlet be the gas exchange membrane (8) which is permeable to the gases required for and arising during the cell culture, forms at least part of the outer wall of the culturing vessel and has an overall surface area, material and thickness chosen such that the permeability for oxygen per 10<7> cells is at least 0.01 mg/h. Furthermore, methods of cell culturing are known in which a nutrient medium flowing around a production chamber (15), which is closed on all sides and receives the cell culture (23) to be cultured, is introduced into a culturing vessel and the culturing vessel is induced to execute a continuous rolling movement. In order, starting from this, to specify a method which is easy to carry out and achieves high cell densities coupled with a high vitality within a short period, the production chamber is charged with the cell culture to be cultured in such a way that it contains an air bubble (24) whose volume occupies 10% of the volume of the production chamber and superimposes a tumbling movement on to the rolling movement such that the air bubble in the cell culture is moved.

Abstract: In an irradiation arrangement at least one disc filter (7) is arranged in the light emerging from a lamp (3) with a reflector (4). The filter is used to mask (block) out light waves having wavelengths above a limiting wavelength, whereas the light which is below the limiting wavelength passes through the filter. In this arrangement, the invention is characterised in that the filter (7) has at least one filter disc (5, 6) which is arranged inclined in such a way that it essentially reflects the light waves to be masked out and deflects them outwards laterally from the beam path while passing the light which is below the limiting wavelength. <IMAGE>

Abstract: Substrates containing anti-agglomerating agents possess better flowability during preparation, improved structural integrity, and uniform porosity. Mixing the anti-agglomerating agent with the fibers and resin during preparation and sifting the mixture inhibits fiber bundling and resin agglomeration. The anti-agglomerating agent surrounds the fibers preventing a static charge from building thereon. As a result, the inter-fiber attraction decreases, thereby inhibiting fiber bundling and resin agglomeration.

Abstract: A rotary accelerometer (1) has capacitively coupled rotary (5) and fixed (7a,7b) thin film electrodes fixed to a substrate (3). The rotary electrode (5) is angularly flexible and has a central hub (5a) secured to the substrate (3) and spoke electrodes (5b) radially extending from the hub (5a). Elongated electrodes (7a,7b) are fixed to the substrate (3) in circumferential positions on each side of each spoke electrode (5b) and in the same plane as the spoke electrodes (5b). The rotary electrode (5), having a mass and being angularly flexible, responds to angular acceleration to differentially change the gaps between its spoke electrodes (5b) and the adjacent fixed electrodes (7a,7b). The fixed electrodes (7a,7b) are energized with rectangular wave voltages of opposite phase. The sum of these voltages in the spoke electrodes (5b) is a function of the difference in the gaps which, in turn, is a function of the angular inertia of the rotary electrode (5).
