Title: Dispositif a emission de champ d'electrons confines et son procede de fabrication
Inventor: POTTER MICHAEL
IPC: H01J31/12
Filed: 1999-02-06
Abstract: La présente invention concerne un dispositif à émission de champ avec émetteur latéral (10) comportant une électrode de grille (60) qu'une couche isolante (80) sépare d'un milieu sous vide ou rempli de gaz en microchambre (20) comprenant d'autres éléments du dispositif (10). Par exemple, l'électrode de grille (60) peut être disposée à l'extérieur de la microchambre (20). La couche isolante (80) est disposée de façon à ne pas créer de trajet sous vide ou à gaz en direction de l'électrode de grille pour les électrons émis par l'émetteur latéral (40, 100). La couche isolante (70, 80) disposée entre l'émetteur et l'électrode de grille comprend de préférence un matériau présentant une constante diélectrique supérieure à un. De plus, la couche isolante a de préférence un faible rendement d'électrons secondaires dans les limites d'utilisation des énergies électroniques de fonctionnement du dispositif. Pour des applications dans des écran d'affichage, la couche isolante est de préférence transparente. Par ailleurs, les électrons sont confinés dans la microchambre (20) contenant leur émetteur (100). Par conséquent, la composante courant de grille d'électrode du courant de l'émetteur ne comprend qu'un courant de déplacement. Ce courant de déplacement est le résultat de tout changement de potentiel dans l'électrode de grille par rapport aux autres éléments, par exemple, par rapport à l'émetteur. On coupe par ailleurs le courant d'électrons directe allant de l'émetteur à l'électrode de grille. Un réseau fait de ces dispositif comprend un réseau de microchambres de sorte que le courant électronique provenant de chaque émetteur (100) n'atteigne que l'anode (50, 55) dans la même microchambre, même pour les dispositifs à diodes exempts d'électrode de grille (60). Enfin, un procédé de fabrication (S1-S28) est spécialement conçu pour la fabrication de ce dispositif et de ses réseaux.

Abstract: A feedforward amplifier network (42) generates a fixed offset frequency swept pilot tone (46) over at least the same frequency band as an input signal (40).  The fixed offset frequency swept pilot tone (46) is a function of a variable frequency reference signal (52) and a fixed pilot tone clock signal (54). A  mixer arrangement (66 and 70), as opposed to a phase lock loop arrangement, helps ensure that the fixed frequency offset can be generated over the swept range. In addition, the feedforward amplifier network (42) incorporates a delay (58) which is added to the variable frequency reference signal (52) and used by a pilot tone detector (57) so that the pilot tone generator (44) and pilot tone detector (57) are in synchronization over narrow bands to accommodate pilot tone detection in the presence of code division multiple acces channels that are relatively close together.

Title: Method and device producing co2 gas for trapping insects
Inventor: WIGTON BRUCE E
IPC: A01M1/02
Filed: 1999-01-21
Abstract: An insect trapping device generates its own insect attractants of carbon dioxide (CO2), heat and water vapor through catalytic conversion (84) of a hydrocarbon fuel in a combustion chamber (68). The hot insect attractants generated in the combustion chamber are diluted and cooled to a temperature above ambient temperature and below about 115 ~F by mixing with air, and then the mixture is exhausted downward through the exhaust tube (48). A counterflow of outside air (52) is drawn into the trap through the suction tube (32) that concentrically surrounds the exhaust tube. Biting insects are captured in a porous, disposable bag (34) connected to the other end (36) of the suction tube. A thermoelectric generator, including thermoelectric modules (102) coupled to the combustion chamber generate power for fans (38, 64) that provide the exhaust flow and the suction flow. Additional chemical attractants may be used with the device to make the trap even more effective. The trap may be adapted for trapping different types of insects by adjusting airflow velocities and attractants.

IPC: A61K45/00
Filed: 1999-04-15
Abstract: The present invention relates to mammals into which foreign DNA has been introduced or in which various modifications or substitutions have been made to an integrin .beta. subunit, thereby generating transgenic or genetically-engineered non-human mammals. In particular, the present invention provides a transgenic mammal in which the endogenous GP IIIa gene has been replaced with an altered or mutant GP IIIa gene in which one or all of the phosphorylatable cytoplasmic tyrosine residues have been replaced with non-tyrosine residues such as phenylalanine. Since the platelets in the blood of the resultant transgenic mammals expressing the altered or mutant GP IIIa cannot undergo tyrosine phosphorylation to the extent that it occurs in wild-type mammals, these genetically-engineered animals provide a critical tool for assessing the importance of the phosphorylation reaction for platelet function. The invention is also useful for studying the effect of the mutant GP IIIa integrin subunit on biological processes other than platelet formation.

Filed: 1999-09-14
Abstract: This invention relates to metallurgy and machine building, more specifically  to the development of a method that improves service life, durability and repai r of machine components by applying coatings to working surfaces followed by special treatment of the surfaces.  The essence of the invention is deposition of erosion and corrosion resista nt coatings on machine components, that comprises a plurality of microlayers wherein each of the microlayers comprises one or more elements selected from the transition metal group, solid solutions or interstitial phases based thereon, and where in one or more of the microlayers is subjected to high energy non-metallic ion deposition that causes changes in structure and composition of the deposited microlayer thus improving performance characteristics. After the full coating has been deposited, a vibromechanical treatment with micro-pellets is applied to the surface of machine components, that improves distribution of residual stresses.  The method makes it possible to deposit coatings having high resistance to wear and corrosion, and having a sufficient level of fatigue strength of machine components, primarily gas-turbine compressor blades and vanes.

Patent CA-2340207-A1 (CA)
Inventor: NAKAMURA KENJI
IPC: H01M4/58
Filed: 1999-07-16
Abstract: The internal resistance associated value associated with the internal resistance of a secondary cell is collated with the correspondence relationship grasped in advance between the internal resistance associated value and the cell state by a predetermined method, and thereby the cell state of the secondary cell is judged. Since the internal resistance associated value is a value associated with the internal resistance which is in a close relationship with the cell state, the cell state is judged precisely from the relationship. The internal resistance associated value is found out by a predetermined method in a short time. If the degradation of the negative plate is low, only the electrolyte is supplied; if the degradation is high, a reducing agent is added to the electrolyte so as to regenerate the cell. By such a regenerating method, the performance of the negative plate can be restored without degrading the positive plate.
