Patent EP-0660412-A1 (EP)
Inventor: WOLF RONALD MARTIN
IPC: H01L27/11502
Filed: 1994-12-14
Abstract: The invention relates to a switching element provided with two electrodes (1, 2) with a semiconducting dielectric (3) therebetween, one electrode (2) comprising a material which forms a Schottky contact with the semiconducting dielectric (3), while a space charge region (3') of the Schottky contact forms a tunnelling barrier for electrons during operation. It is desirable in many applications for the switching element to hold a certain switching state, such as open/closed, during a longer period. The switching element may then be used, for example, as a memory element. According to the invention, the switching element is characterized in that the dielectric (3) comprises a ferroelectric material with a remanent polarization which influences a dimension of the tunnelling barrier. It is achieved thereby that the switching element has various switching states depending on the remanent polarization of the dielectric (3). These switching states are held until the polarization of the dielectric (3) changes.

Abstract: The present invention provides a process for the preparation of a polyester from an acid component comprising terephthalic acid or a lower alcohol ester thereof as a main component and a diol component comprising 1,4-butanediol as a main component, wherein 0.001 to 0.5 mol % (based on the acid component) of a specific aromatic sulfonic acid compound is dissolved in the diol component or a mixture of the diol component with the acid component and thereafter a catalyst is added to the resulting reaction system to conduct esterification (or transesterification) and polycondensation successively, for the purpose of providing a modified polybutylene terephthalate resin which little generates gas such as tetrahydrofuran even in high-temperature service and little gives sublimate in melting.

Abstract: The cleaning of the brewing apparatus (3) of the coffee brewer takes place in various stages. In a first stage, water is fed from a water container, via the water connection (13) of the brewing cylinder (14), through the outflow pipe arranged in the brewing plunger (26), to an external water container. The cleaning water follows the path of the brewed coffee in this stage. In a second stage (see fig. 3), the cleaning water is led from the brewing cylinder (14), via channels (25) arranged in the wall (24) of the brewing cylinder (14), into regions outside the brewing cylinder and cleans, inter alia, the second projecting part (16) for the feeding of the coffee residue to the residue container. In a third stage, by displacing the expelling plunger (19), the water situated in the brewing chamber is caused to flow out over the edge of the brewing cylinder. In a fourth stage, a chemical or biological cleaning agent is introduced into the brewing chamber via the powder shaft, or from a cleaning-agent tank, or from the water tank, or from a cartridge, water then being conveyed into the brewing cylinder, and this process being repeated several times. Lastly, a rinsing operation takes place. <IMAGE>

Abstract: Um Störbeeinflussungen bei der Bestimmung der radbezogenen Geschwindigkeiten von Drehgestellen auszuklammern, werden aus den jeweils detektierten Ereignismeldungen die Ereignismeldungen der jeweils letzten Achse des Drehgestelles bestimmt. Dies geschieht durch Vorgeben eines Zeitfensters (tR), innerhalb dessen die letzte Achse eines Drehgestelles die Meßstrecke passiert haben muß. Diejenigen Ereignismeldungen (R2EM1, R2EM2) werden für die Bestimmung der Geschwindigkeit dieser Achse herangezogen, deren zeitlicher Versatz (tVe) gleich dem zeitlichen Versatz (tVa) der Ereignismeldungen (R1EM1, R1EM2) der ersten Drehgestellachse sind. Eine zusätzliche Plausibilitätsprüfung erhöht die Zuverlässigkeit der Zuordnung der Ereignismeldungen zu den veranlassenden Radsätzen. Die zusätzliche Plausibilitätsprüfung umfaßt die Auflistung und Summenbildung bestimmter Zeitmeßwerte, die von den beiden Ereignismeldern der Meßstrecke detektiert wurden. Die Zuordnung der Zeitwerte jeweils zu den Impulsmitten der Ereignismeldung gestattet die Ausblendung von unterschiedlichen Ansprechtoleranzen der einzelnen Ereignismeldern in Abhängigkeit vom seitlichen Versatz der Fahrzeugräder gegenüber den Schienen im Bereich der Ereignismelder. Durch die Anwendung des erfindungsgemäßen Verfahrens ist es möglich, die Geschwindigkeit von Fahrzeugen und Fahrzeugverbänden beim Passieren einer Meßstrecke fortlaufend zu bestimmen, selbst dann, wenn die Ereignismelder störungsbedingt auf Magnetschienenbremsen oder Wirbelstromschienenbremsen an den Fahrzeugen ansprechen.

Abstract: Methods and compositions for the prophylaxis and/or treatment of sexually transmitted diseases (STDs) are disclosed, in which amounts of a haloperoxidase, such as myeloperoxidase or eosinophil peroxidase, and a semen substrate-specific oxidase are administered to a human or animal subject in the environment of sexually transmitted fluids. In the presence of semen, the semen substrate-specific oxidase catalyzes the production of hydrogen peroxide, which in turn is utilized by the haloperoxidase to selectively inhibit pathogenic microbes present in the sexually transmitted fluids. At high concentration levels, the compositions additionally exhibit spermicidal properties.

Abstract: Changement de vitesses commandé par ordinateur à l'aide d'un actionneur d'embrayage automatique pour véhicules à boîte de vitesses manuelle. Ledit changement de vitesses est composé de servomécanismes, de capteurs électriques, de capteurs magnétiques, de capteurs potentiométriques résistifs, et d'actionneurs électriques, tous ces dispositifs étant reliés à une unité centrale de commande (8) à microprocesseur, et commandés par celle-ci, ladite unité étant destinée à exécuter un ensemble d'instructions particulières de manière à rendre automatiques toutes les opérations de changement de vitesses et d'embrayage dans un véhicule équipé d'une boîte de vitesses manuelle, de sorte que cette dernière fonctionne à la manière d'une transmission automatique en évitant les pertes de puissance d'une transmission hydraulique et en étant plus économique, les spécifications du fabricant du véhicule relatives à la transmission moteur-roues étant également respectées. En outre, l'appareil est composé d'un servomécanisme d'embrayage commandé par l'unité centrale de commande (8) à microprocesseur, et adapté pour régler avec précision le positionnement de l'embrayage en un point donné de sa course. A cet effet, il fournit un signal analogique à l'entrée non inverseuse d'un circuit additionneur électronique (10) par l'intermédiaire de la sortie d'un convertisseur numérique-analogique (9), ledit additionneur électronique étant à son tour adapté pour recevoir, au niveau de ses deux autres entrées inverseuses, des signaux de rétroaction générés par la rotation de l'axe du servomoteur d'embrayage, l'un des signaux étant proportionnel à la position angulaire de l'axe détectée par le potentiomètre résistif (7) tandis que l'autre signal est proportionnel à la vitesse angulaire de sa rotation. Le résultat dudit additionneur électronique est amené à un amplificateur de puissance (11) entraînant le moteur à courant continu (1) dans l'un ou l'autre de ses sens de rotation possibles. Le mode de réalisation décrit jusqu'ici est appelé bloc A, lequel constitue à son tour un seul élément d'un servomécanisme plus complexe possédant d'autres pièces: la pédale d'accélérateur commandant le bloc B, à savoir le moteur (moteur de propulsion du véhicule) fournissant un couple M à l'entrée non inverseuse d'un circuit additionneur mécanique (10') qui, en l'absence de charge, correspond à la rotation de l'axe du moteur du véhicule telle qu'elle est retardée par le moment d'inertie. Lorsque le véhicule commence à rouler, le circuit additionneur électronique (10) établit et détecte une vitesse de rotation (tours/minute) de consigne ou de seuil.
