Title: Dispositif de protection pour ligne d'énergie électrique
Inventor: SOUILLARD MICHEL
IPC: H02H3/48
Filed: 1980-10-06
Abstract: L'invention concerne les protections utilisées sur les lignes de transfert d'énergie électrique à courant alternatif. Un mode de réalisation d'un appareil mettant en oeuvre l'invention comporte des moyens détecteurs d'impédance ayant une caractéristique d'impédance définissant au moins trois zones, pouvant être distinguées les unes des autres dans leur diagramme RX, et étant agencés pour produire des signaux respectifs différents à raison de un par zone, indiquant la zone dans laquelle se trouve l'impédance détectée. Le trajet du point représentatif de l'impédance apparente de ligne à travers ces zones est différent selon qu'il s'effectue sous l'effet d'une rupture de synchronisme des générateurs alimentant la ligne ou de simples oscillations de puissance. Un circuit est prévu pour effectuer cette distinction. Application à la détection des pertes de synchronisme.

Abstract: La lithographie, par rayons ioniques presente un interet particulier dans la fabrication de circuits integres a grande echelle, dont la capacite de traitement etonnamment elevee est le resultat du choix approprie du a) materiau de reserve et b) des especes d'ions. Le materiau de reserve, generalement a action negative, est caracterise par une sensibilite aux rayons electroniques inadequate a la lithographie commerciale ordinaire aux rayons electroniques. La caracteristique pertinente responsable de la sensibilite inadequate aux rayons electroniques est la caracteristique meme responsable d'une sensibilite ionique accrue. Les especes ioniques, toujours de nombre atomique plus grand que celui du proton, sont dictees par l'observation que la sensibilite augmente de maniere inattendue a une vitesse plus grande qu'elle n'est previsible d'une maniere traditionnelle.

Abstract: A gas fitting is proposed which is in particular utilisable for heating furnaces and boilers, and which can be equipped both with a thermoelectric safety pilot and with a safety pilot based on the ionisation principle. The gas fitting has a safety pilot valve whose closure member is acted on by a closing spring and a magnetic actuator of the safety pilot. The valve seat of the safety pilot valve faces the operating side of the fitting and the valve chamber (20) lying in front of the valve seat can be closed in the direction of the operating side by a lid-like casing part (12, 12') to which the magnetic actuator (50, 50', 76) of the safety pilot is fastened. When a thermoelectric safety pilot is used, a manually operated actuator (94) is mounted on said lid-like casing part (12, 12') at the side of the magnet insert (76) of the safety pilot, said actuator (94) acting by means of a rocking lever (82) on the armature of the magnet insert and on the closure member (2) of the safety pilot valve. This has the effect that for both types of safety pilot the casing of the fitting can have one and the same main part. The magnetic actuator of the safety pilot is disposed on the operating side of the fitting. <IMAGE>

Abstract: A batch chip placement system and method for positioning semiconductor chips (24A, B, C) or the like upon a substrate (15) containing an array of chip sites or footprints whose actual position on the substrate deviates from the theoretical or nominal position over successive substrates. The positioning is achieved by first sensing the X and Y offsets of a pair of alignment marks (15A, 15N) on the substrate from their theoretical or nominal position to determine the AX and ΔY correction factors required to obtain the actual X/Y position of the alignment marks. The actual X/Y position of the alignment marks is used to determine actual X/Y chip position values, 6 rotation and shrinkage factor corrections required to obtain proper orientation and positioning for batch chip placement.

Abstract: A random number generator and a gaming machine employing such random number generator are set forth in accordance with preferred embodiments of the present invention. The random number generator disclosed employs a white noise source to clock a counting arrangement whose maximum count exceeds the largest random number desired. A variable counter clocked at a fixed rate, is loaded with random numbers obtained from the counting arrangement and each time the variable counter is counted down to a threshhold state a new random number is read from the counting arrangement. Random numbers obtained in this manner are then checked to ascertain their propriety and those which are accepted are then subjected to pseudo-random number regenerative techniques to further randomize the same. The resulting random numbers are then employed within a digitally controlled and operated gaming machine to select winning condition, the probabilities to be displayed during periods when wagers are accepted and otherwise to vary initial conditions associated with the gaming event prior to the actual occurrence thereof. The gaming event is then visually displayed in accordance with the winning conditions selected and any successful wagers are paid.
