Inventor: POHJALAINEN PASI
IPC: H02P21/34
Filed: 1993-07-01
Abstract: The invention relates to a method of determining rotational speed, size and instantaneous direction of a residual flux of an inverter-supplied squirrel cage induction machine, to be used for starting the squirrel cage induction machine when there is a rotating residual flux (g(C)s) in the machine (1) and a total leakage inductance ((sigma)Ls) of the machine is known. According to the invention measures are taken, comprising steps of short-circuiting stator windings; measuring a first stator current vector (is1) and switching off the stator circuit at the end of a first time period (T1); short-circuiting the stator windings once more after a second time period (T2) from the end of the first time period (T1); measuring a second stator current vector (is2) and switching off the stator circuit after a time identical with the first time period (T1) from the second short-circuiting; determining the frequency (g(C)s) of the residual flux ((omega)s) on the basis of the directions of the first and the second stator current vector (is1, is2) and the lengths of the first and the second time period; determining the size of an absolute value (]g(C)s]) of the residual flux on the basis of the total leakage inductance ((sigma)Ls) of the squirrel cage induction machine and the first or the second stator current vector (is1, is2); and determining the instantaneous direction of the residual flux (g(C)s) on the basis of the direction of the first or the second stator current vector (is1, is2).

Abstract: L'invention concerne un système pour déployer des radeaux de sauvetage pneumatiques sur des bateaux. Les radeaux de sauvetage (2, 3) sont du type gonflable et des tubes (7) similaires à des bas sont ménagés pour transférer le personnel du bateau à au moins un des radeaux de sauvetage. Les radeaux de sauvetage sont disposés en groupes et connectés de manière libérable à une structure inférieure commune (1). Chaque groupe comprend un radeau de réception (2) et plusieurs radeaux d'évacuation (3) connectés de manière libérable au radeau de réception (2). Ladite structure inférieure (1) est suspendue à partir d'au moins un câble de treuil (4) disposé à partir d'une membrure support (5) pouvant se déplacer d'une position de parcage à l'intérieur du bateau vers une position d'utilisation à l'extérieur du bateau. Lorsque la membrure support (5) est en position d'utilisation, la structure inférieure (1) peut être abaissée dans l'eau à l'aide du treuil (8). Les câbles (4) du treuil passent dans des glissières de guidage (6a) au fond du radeau de réception et dans des glissières de guidage (6b) dans un tube de sauvetage en forme de bas (7) connu en soi qui s'étire entre la membrure support (5) et le radeau de réception (2). Le radeau de réception se gonfle automatiquement lorsque la structure inférieure (1) est abaissée sous la surface de l'eau alors qu'au même moment les radeaux d'évacuation (3) restent à flot, dégonflés, à côté du radeau de réception (2) et reliés à lui de manière libérable. Le mécanisme de gonflage des radeaux d'évacuation peut être actionné manuellement depuis le radeau de réception selon les besoins, de manière à maintenir une voie de sauvetage sans danger, continue, du pont du bateau aux radeaux d'évacuation.

Abstract: L'invention concerne un procédé permettant d'essayer les transferts dans les réseaux de téléphonie mobile. On fait passer un mobile d'essai sur des itinéraires pertinents alors qu'il émet un signal radio et enregistre sa position. Des stations de base mesurent de façon synchrone l'intensité du signal reçu de ce mobile d'essai. Les valeurs obtenues sont compilées dans une base de données de mesures des positions enregistrées pour ce mobile d'essai à différents instants. On peut alors procéder à des essais de transferts en faisant varier des paramètres de transfert choisis pendant une période puisée dans la base de données de mesures. La mesure s'effectue donc sur la liaison montante, ce qui procure une base réaliste pour déterminer un algorithme de transfert souhaité. L'invention permet, avec un seul jeu de mesures, d'effectuer des essais portant sur un grand nombre d'algorithmes sans perturber le réseau.

Abstract: When an automatic circuit tester (10) detects that a fault has occurred in a circuit board (14), it applies to the circuit board (14) a sequence of vectors that differs from the test sequence (T n , T n+1 ) by which the fault detection occurs only in that each vector's component that corresponds to an input pin in question on the board device under test maintains a level that simulates an open circuit at that input pin. If the resultant response differs from the response to the original test sequence, the input pin can often be ruled out as one at which a fault has occurred. In this way, many open-circuit faults at input pins can be diagnosed without special probing, even when several such faults occur simultaneously.

Abstract: A surface-imaging technique for lithographic processes is disclosed. The lithographic processes are used to manufacture integrated circuit devices. An image is produced on a resist that is applied onto a substrate. The image is produced by exposing selected regions of the resist material to radiation. The selected exposed regions correspond to the image. The resist is then exposed to a silylating reagent that selectively reacts with either the exposed or the unexposed region of the resist. The silylated resist is then subjected to reactive ion etching, which forms an  in   situ  silicon oxide etch mask over the silylated regions of the resist. The mask so formed provides etching selectivity which provides precise image transfer from the resist into the substrate.

Abstract: The process according to the invention, intended for treating the pollution of polluted aquatic media, consists in using microorganisms, not in their state of preservation but in their growing state. Thus, before putting the metal organisms in the polluted water, the process consists in placing them in a device intended to activate them in order to change them from their state of preservation to their growing state. The device according to the invention carrying the general reference (100) comprises activation means (AM), control and adjustment means (CAM) and distribution means (DM). The activation means (AM) comprise a main vessel (1) arranged in a secondary vessel (2) and which comprises stirring means (14), heating means (17, 18) and discharging means (22, 23). The main vessel (1) forms an activation chamber (3) and consists of a cylindrical peripheral wall (4) extended towards the bottom by a rounded bottom wall (5). The said vessel is hermetically closed, at its top part, by a lid (6) movable between an open position and a closed position. The said main vessel (1) is housed in a secondary vessel (2) of greater dimensions in order to create an intermediate space (7) around the said main vessel (1). The secondary vessel (2) comprises a side peripheral wall (8) as well as a bottom wall (9) and a top wall (10) which comprises a filling hole (11) closed by a removable cap (12). In order to maintain bacteriological liquid (13) at a sufficient temperature, namely between 10@C and 70@C, the main vessle (1) is in a water bath consisting of the secondary vessel (2) in which the water (17) is heated by the heating resistance (18). Once the concentration has been obtained, the treating liquid (13), comprising the bacteria in the growing state, is distributed by diffusion into the medium to be treated. The bacteria continues to grow in the said medium for a certain time (c), until at their equilibrium state (d) which reflects an optimal activity. During this equilibrium state (d), the bacterial population remains stable: this is the maximum biological treatment phase. <IMAGE>

Abstract: The microwave antenna (2) which is fed from the outside via a connection line (1) is designed as a folded dipole (3) which is insulated and wound in the form of a double helix (4) over an essentially cylindrical, conducting support body (6) which can also be formed directly by the terminal region (8) of the shielding (9) of a coaxial cable (7) serving as connection line (1). By displacing the feed point of the connection line (1) out of the centre of the double helix (4) the input resistance of the microwave antenna (2) can be easily adapted to the characteristic impedance of the connection line (1). Overall, this results in a stable resonance of the microwave antenna (2) and holds back radiation of the connection line (1). <IMAGE>
