Abstract: L'invention se rapporte à un procédé de fabrication d'une mémoire utilisant un film ferro-électrique, grâce auquel on obtient une mémoire à substance ferro-électrique dans laquelle les informations peuvent être réécrites en un seul mot un grand nombre de fois et qui possède de bonnes caractéristiques quant à la tension de rupture et au courant de fuite, etc., en formant un film de polysilicium entre une couche de diffusion à concentration élevée en impuretés destinée à servir de région source ou de région de drain, et une électrode d'un film électrode à substance ferro-électrique. Un trou de contact est pratiqué dans un film isolant intercouche (111) situé sur la couche de diffusion à concentration élevée en impuretés (103) destinée à servir de région source ou de région de drain et formée sur un substrat semiconducteur. Après avoir formé par croissance épitaxiale sur ce substrat une couche de polysilicium (106), une électrode inférieure (107) et une couche à substance ferro-électrique (108) son formées. La couche ferro-électrique, l'éléctrode inférieure et la couche de polysilicium sont ensuite attaquées par gravure sélective. Etant donné que le gradin formé par le trou de contact est peu marqué grâce à la présence de la couche de polysilicium, l'épaisseur du film ferro-électrique est uniformisée et les caractéristiques de la mémoire sont améliorées.

Abstract: Described is a chamfer cutter, in particular one with two blades made of hardmetal, the two blades being mounted opposite each other in the head of a drilling/chamfering tool. The cutter is located across the diameter of the spiral face of the drill so that the chamfer angle can be adjusted, and disposed so that it can be fixed over 45 DEG -angled faces (7, 8) along the top (9) of the cutter. Significant for the invention is that the cutter has a four-sided body for smooth movement in the longitudinal, or adjustement, direction. The contact surface (15) and the sides (B) of the body have matching lateral guide surfaces (1, 3) which work smoothly with a U-section holding/guide bar located in the chamfering head. In addition, the sides (B) of the cutter body and the cutting-edge separation (B') are machined to the same dimensions and tolerances in the same machining pass to the same extent. This ensures that the cutter blade concerned is inserted into the diagonally opposite corner of the U-section holder so that, when the cutter blade is changed or displaced, the cutting edge always stays mounted in the same position.

Abstract: A process and device allow transversal and longitudinal cracks to be marked on masticatory surfaces on crown moulds in dentistry by means of a simple mechanical device. The marking device (1) has at least a supporting arm (12) and at least a working arm (3) between which a defined angle is set. The advantage of the marking device (1) lies in the fact that it can be suported on an articulated part of an articulator, so that the centre of rotation of the marking device (1) lies at the position of the geometric central point of a condylar sphere on the axis of a hinge of the articulator. Longitudinal cracks can thus be marked on models by making an outer end of the working arm (2) describe an approximately circular orbit the center of which lies in the central point of the opposite condylar sphere of an articulation of the articulator. Transversal cracks can be marked by making the outer end of the working arm (2) describe an approximately circular arc the center of which lies in the central point of the condylar sphere on the same side of the articulation of the articulator. The invention has the particular advantage of allowing the Benett shift to be taken into account during marking by means of a coaxially rotatable guiding arm (23).

Abstract: On décrit un procédé et un appareil permettant de faire des économies d'énergie et de former des enroulements de fibres de verre sur une bobine (24) qui sont exempts de migration. On fait passer de l'air qui entoure la filière (12) de formation de fibres au-dessous de la filière; l'air est chauffé par la tête de la filière et l'air chauffé est ensuite aspiré dans une chambre (36) à travers laquelle les fibres de verre (16) passent en étant en contact de transfert de chaleur avec l'air chauffé. Ce contact de transfert de chaleur provoque l'évaporation de l'eau ou du solvant contenu dans l'ensimage appliquée et permet d'obtenir des enroulements exempts de migration.

L'un des quadrupoles est enroulé dans une configuration d'enroulement + - +, alors que le quadrupole adjacent est enroulé dans une configuration d'enroulement - + + -. Cet agencement de quadrupole inversé élimine essentiellement les erreurs dépendant des gradients de température radiaux variables dans le temps et réduit les erreurs dépendant des gradients de température axiaux variables dans le temps, lesquelles peuvent etre essentiellement éliminées par un enroulement en octupole inversé, qui présente une configuration d'enroulement + - - + - + + - - + + - + - - +. Dans une variante, on peut éliminer essentiellement les erreurs dépendant des gradients de température axiaux variables dans le temps à l'aide de longueurs supplémentaires des extrémités 'x' et '-', que l'on déplace axialement de manière à éliminer lesdites erreurs.
