Patent EP-0444203-A1 (EP)
Inventor: BAHN ITSUKI
IPC: H02P25/08
Filed: 1990-09-17
Abstract: Moteur triphasé à réluctance dans lequel un rotor (1) reçoit la force d'attraction magnétique dans un sens à tout moment sans annuler la force d'attraction magnétique, afin de réduire les vibrations mécaniques. Par rapport aux moteurs conventionnels, ce moteur présente en outre moins de pôles magnétiques (16a, ---) et moins de pôles saillants (1a, ---), ce qui permet de réaliser un moteur basse puissance de faibles dimensions. Trois moteurs triphasés à réluctance sont logés dans le même logement, les forces d'attraction magnétiques dans le sens radial d'un moteur à réluctance au centre et de deux moteurs à réluctance de chaque côté sont équilibrées dans deux sens opposés l'un à l'autre, de manière à laisser une force d'attraction déterminée. Par conséquent, les forces d'attraction magnétiques ne poussent pas les paliers, et la durée de vie n'est pas raccourcie. Des paires de pôles magnétiques (16a, ---) de chacune des phases sont excitées pour former des pôles N et S, de sorte que le moteur présente un couple élevé de sortie et un rendement élevé.

Filed: 1990-08-20
Abstract: Un protocole d'échange de signaux de commande à transfert rapide pseudosynchrone utilisable sur un bus VME (22) ayant un module de fonction maître (300) et un module de fonction en mode asservi (200) sont interconnectés logiquement au moyen d'un bus de transfert de données. Le bus de transfert de données (22) comprend une ligne de signal d'échantillon de données (D50, D51) et une ligne de signal de récpetion du transfert de données (DTACK). Pour effectuer l'échange de signaux de commande, le maître (300) transmet un signal d'échantillon de données d'une durée donnée sur la ligne d'échantillons de données. Le maître attend ensuite la réception d'un signal de réception du transfert de données provenant du module en mode asservi (200) sur la ligne de signal de réception du transfert de données. Le module en mode asservi répond alors en transmettant un signal de réception du transfert des données pendant une durée donnée sur la ligne de signal de réception du transfert de données.

IPC: H01L21/338
Filed: 1991-01-02
Abstract: In a dual gate FET of this invention, the number of points (A, B, C) for supplying signals to a first gate electrode (20) and the number of points (A', B', C') for supplying signals to a second gate electrode (30) are set to be optimal values so that a noise index is minimized. A difference in electrical length between each signal supply point of each of the first and second gate electrodes (20, 30) and the corresponding gate input terminals (22, 32) has a negligible magnitude with respect to a quarter wavelength of an input signal applied to the corresponding gate input terminal (22, 32). The dual gate FET has a low-noise arrangement, and a microwave can be applied to either one of the first and second gate electrodes (20, 30), thereby obtaining, e. g., a low-noise mixer. In this case, a separator required upon use of a single gate FET can be omitted, thereby easily arranging a monolithic IC.

Abstract: Herein disclosed are a microwave plasma treating method and a system therefor. A slow wave structure (19) is disposed in the propagation region of microwaves, and the microwaves are thus introduced at a delayed phase velocity into a discharge chamber 10 in which gases are transformed into plasma. Thus, the phase velocity of the microwaves is adjusted to a relatively low velocity, at which charged particles are distributed most densely in the plasma, so that the energy may be efficiently transformed to much more charged particles in the plasma. Thus, the plasma of high density is generated to improve the plasma treating rate.

Abstract: A fuel delivery system for an aircraft gas turbine engine which provides a monitor intended to estimate, from actual engine starting or operating conditions, whether the fuel delivery system is capable of meeting predetermined operating specifications, such as adequate capacity for a windmill restart. The differential pressure regulating valve (60), which is normally provided to maintain a constant pressure drop across the metering valve which meters fuel to the jet turbine engine, has a position monitor (82) associated therewith. A signal (80) relating to the regulating valve position is processed along with a signal (84) indicating the corresponding actual engine operating conditions, to determine "excess capacity" at the operating condition and estimate from that information whether the engine will likely be capable of meeting worst case demands.

Title: Dual bus communication system
Inventor: WATSON GREGORY CHARLES ADAM
IPC: H04L12/407
Filed: 1991-06-12
Abstract: A communications system has a plurality of stations (S₁,S₂ ... S N ) interconnected by a pair of uni-directional, oppositely-directed signal paths (A,B). For transmitting data down one path (A), frames are passed down the path (A) and each station (S₁, S₂ ... S N ) can write a packet of data to any frame which is empty. The stations (S₁, S₂ ... S N ) are arranged to operate in cycles in each of which a station can transmit up to a given number of packets. The stations (S₁, S₂, ... S N ) are operative to cause the frames to present a reset-request indication when all stations so far passed have completed packet writing in their current cycles. When a tail station (S N ) receives this indication, it knows all stations have finished their cycles and it transmits a reset signal on the other path (B) to initiate new station cycles. In order to increase the overall efficiency of the system in cases where only a single station wishes to transmit, each station is arranged to propagate a reset-request indication when starting a new cycle as well as upon cycle completion and to remember if any resets are received during the packet writing phase of its cycle.

Abstract: Expedient fabrication of fine-featured integrated circuits entails aperture pattern delineation (12) to produce a masking layer atop a semiconductor body followed by insertion within a controlled atmosphere chamber within which device-functional layered material is epitaxially grown within apertures. Critical, device-consequential properties of epitaxial material is assured by removal of a thin surface layer of material (15) revealed during delineation. Such removal, sufficient to eliminate meaningful contamination and/or crystalline damage introduced during delineation, is of sufficiently small quantity as to be accommodated within the chamber. Under most circumstances, the controlled atmosphere is at reduced pressure as required for e.g. MOMBE epitaxial growth.

Abstract: A new instrumentation amplifier design uses three operational amplifiers (op amps) (A4, A5, A6), each of which has a feedback circuit connected from its output to its inverting input. The first op amp (A4) has a unity gain feedback (2), and is connected through a gain setting resistor (Rg) to the inverting input of the second op amp (A5). The output of the third op amp (A6) is connected through a resistor (R5) to the inverting input for the second op amp (A5), while the third op amp's (A6) non-inverting input is connected to one of the second op amp's (A5) inputs. Differential voltage input signals (V INM , V INP ) are applied to the non-inverting inputs of the first and second op amps (A4, A5), while a reference voltage (V ref ) is applied to the inverting input of the third op amp (A6). The circuit is capable of operating with a single voltage supply (V+) by setting the negative voltage supply (V-) together with the reference voltage (V ref ) at ground potential. It has a simplified gain equation based upon the ratio between the feedback resistor (Rf) for the second op amp (A5) and the gain setting resistor (Rg). Multiple selectable gain setting resistors (Rg1, Rg2, Rg3) may be provided to allow for gain programmability, with a special switching circuit (S1a, S1b, S2a, S2b, S3a, S3b) that isolates the switch resistance from the gain equation.

Abstract: The subjects of the present invention are methods and devices for automatically manufacturing branch-off connections of conductive wire or fibre-optic harnesses, comprising several branches and branch-off connections. The present invention permits the production of branch-off connections which each length of wire of the harness will have to assume:   - by identifying, for each length of wire (7f), the points associated with these branch-off connections by means of their abscissae on each wire (7f) as they progress and by putting them into branch-off gripping elements (3'f), - by forming these branch-off connections by collecting together, in the branch-off gripping elements (3'f), all the intermediate points associated with a single branch-off connection and by picking them up from the gripping elements in which they have been arranged.   The branches (7) of the harness (7a, 7b,..., 7f) are separated and formed by moving these branch-off gripping elements (3'a, 3'b, ..., 3'f) apart. One application is the automatic manufacture of conductor wire harnesses. <IMAGE>
