Title: Roulement sans impuretés
Inventor: YU DABANG
IPC: F16C19/36
Filed: 2001-02-28
Abstract: L'invention concerne un roulement sans impuretés présentant une structure novatrice caractérisé en ce qu'il est exempt de cage de retenue et de friction par glissement à la différence des roulements classiques qu'il remplace. Ce roulement se compose d'une bague interne, d'une bague externe, d'un corps de roulement, d'un corps de roulement de positionnement et d'un anneau de positionnement, toutes ces pièces étant séparées. Le roulement de cette invention permet de remédier aux inconvénients provoqués par l'utilisation de la cage de retenue entraînant un frottement. Par conséquent, la résistance est fortement réduite, la consommation et le bruit s'en trouvent atténués, la vitesse de rotation et la durée de vie s'en trouvent améliorées. De plus, on assure une meilleure précision et une plus grande fiabilité des machines et des équipements moteurs.

Title: Hache ou marteau d'assemblage solide
Inventor: LUO SHUSEN
IPC: B26B23/00
Filed: 2003-09-30
Abstract: La présente invention a trait à une tête de hache ou une tête de marteau comportant un trou borgne d'assemblage et un manche, dans lequel la partie inférieure du trou borgne présente une rétreinte inversée, la forme de la partie médiane ou de la partie supérieure étant tubulaire. Dans l'orifice borgne d'assemblage est prévu un coin inversé dont la forme correspond à la forme du trou borgne, le manche étant de forme tubulaire, dont la partie avant pour l'assemblage est située entre le trou borgne et la partie de rétreinte inversée du coin. Dans cette invention, étant donné que la partie avant du manche est située entre le trou borgne et la partie de rétreinte inversée du coin, lors de l'assemblage de la tête de hache ou de la tête de marteau, en raison de la grande force d'extrusion exercée par le coin inversé, la force de la hache ou du marteau pour une séparation est nettement accrue, améliorant ainsi sa fiabilité, et sa durée de vie est prolongée par plus de deux fois que des haches ou marteaux existants.

Title: Fet-sensor mit besonders ausgestalteter gateelektrode zur hochempfindlichen detektion von analyten
Inventor: OFFENHAEUSER ANDREAS
IPC: H01L29/78
Filed: 2002-12-14
Abstract: Einen Sensor umfassend ein Substrat, ein Source-Kontaktgebiet, ein Drain-Kontaktgebiet und ein Gateoxid eines Transistors, wobei zwischen dem Gateoxid und einer Detektionselektrode, welche aus einem elektrisch isolierenden Material besteht eine Gateelektrode angeordnet ist. Hierdurch liegt eine Reihenschaltung zweier Kondensatoren vor. Die Kontaktfläche Asens der Gateelektrode an die Detektionselektrode ist grösser als die Kontaktfläche Agate der Gateelektrode an das Gateoxid. Dadurch ist gewährleistet, dass der Rezeptor sich auf technisch einfache Weise auf der Oberfläche der Detektionselektrode immobilisieren lässt. Über die kleine Kontaktfläche Agate der Gateelektrode an den Transistor ist gleichzeitig eine hohe Nachweisempfindlichkeit für den Analyten gegeben. Das Verfahren zum Nachweis wenigstens eines Analyten sieht vor, dass wenigstens ein Analyt zur Bildung einer Änderung der elektrischen Ladung an der Oberfläche der Detektionselektrode in Kontakt mit einem an der Detektionselektrode immobilisierten Rezeptor gebracht wird. Der Analyt wird über die Erfassung der Stromänderung am Transistor nachgewiesen.

In order to transmit speech digitally signals are transmitted representing the difference between actual speech samples and predicted speech samples, and the parameters utilized in making the predictions. As described input speech, Fig. 1, is filtered 10, sampled 11 and delayed 12 by 60 samples. The difference # N  is then formed 13 between each sample S N  and a corresponding predicted sample Z N . This difference # N  is then amplified by Q, quantized S 1  N  15 to one of two levels, and transmitted. The quantized difference S 1  N  is amplified by 1/Q, and added 17 to the predicted sample Z N  to produce a reconstructed sample r N  which, together with preceding reconstructed samples, is used 30 to predict the next sample Z N  + 1 The parameters b, k and α utilized in the prediction, and the amplifier gain Q, are also transmitted. All of these parameters are computed 40 every 30 samples (5 msec.) by reference to the preceding 120 samples received direct from the samples 11-delay 12 only being present in order to provide time for this to be done. The Specification contains precise and extensive mathematical information about these parameters and illustrates methods of computing them by block diagrams.
