Patent EP-0407013-A1 (EP)
Inventor: KOSKINEN OLAVI
IPC: B01F27/91
Filed: 1990-05-08
Abstract: The present invention relates to an apparatus for mixing fluids, and especially to a mixer shaft which is provided with a mixing means at the end thereof and which extends from the exterior side of a mixing tank deep into the interior thereof. According to the invention, the mixing shaft is mounted on bearings at a point near the mixing means, and the housing construction of the mixer shaft, including a shield, forms a shape convergent towards the mixing means, which shape contributes to flowing of fluid. For purposes of servicing, the mixer shaft with its drive means may be displaced out of the tank without the necessity of emptying the tank. 
     The above has been achieved in such a manner that the shaft housing (18) with bearings and sealings is disposed inside a shield (56), which extends inside the mixing tank (80) and is attached to a wall thereof so that the mixer is detachable from the tank (80) in such a way that, of the moving parts of the mixer, only the mixing means (64, 66) remain inside the tank (80), whereby emptying the tank is avoided.

Afin de réduire la taille du diaphragme d'actionnement sans rencontrer des concentrations de contrainte excessives au niveau dudit diaphragme, ce dernier (18) peut être actionné par un film de polyimide conjointement avec un corps de vanne (15, 22) en silicium comportant des sièges de vanne (40D à 45D) dont les orifices sont ouverts ou fermés par déflexion du diaphragme (18). On peut micro-usiner des tranches de silicium à l'aide de techniques de fabrication en lots afin de fournir les sièges de vanne (40D à 45D) et les passages (30 à 35) nécessaires au fonctionnement. On produit l'ensemble de vanne (10) sous forme d'un sandwich en couches fait de tranches individuelles, comprenant une couche actuatrice (25), une couche d'arrêt (28), une couche de siège de vanne (15), ainsi qu'une couche (11) dotée de canaux d'écoulement recevant du gaz provenant de la couche du siège de vanne (15) et réalisant les interconnexions nécessaires avec les sorties prévues. Le film du diaphragme (18) est positionné entre la couche du siège de vanne (15) et la couche d'arrêt (22), et est défléchi ou déplacé afin de réguler le passage de gaz par les orifices des vannes. La couche de diaphragme (15) est scellée au corps de la vanne en silicium (15, 22) selon un procédé de fusion, tel que le scellement par brasage ou par une composition vitrifiable.

Abstract: Montre électronique comportant une fonction "heure du voyageur" que l'on peut mettre en marche lorsque l'utilisateur part pour un long voyage vers l'est ou l'ouest par avion, bateau ou autre moyen de transport. Cette fonction fait avancer ou retarder la vitesse de fonctionnement de la montre, de sorte qu'à la fin du laps de temps que dure le voyage et que détermine l'utilisateur, la montre indiquera l'heure locale réelle au lieu d'arrivée et reprendra alors sa vitesse normale de fonctionnement. Le voyageur peut ainsi s'habituer progressivement au changement d'heure dû à son passage par plusieurs fuseaux horaires, en regardant de temps en temps sa montre, de sorte que les effets psychologiques du "décalage horaire" en sont réduits. La montre comprend un microprocesseur (10), un cristal de quartz (20) pour donner une heure standard, un dispositif d'affichage (30) pour afficher l'heure, et une série de boutons (40-90) pour activer les fonctions de la montre. Ledit microprocesseur comprend une série de registres (145 à 160) pour mémoriser l'heure de départ, la destination, et la durée du voyage, et pour commander le fonctionnement de la montre.

Abstract: The machine possesses a horizontal roller (1) which is equipped with beating pins (3) and under the underside of which bar grids (4, 5) are arranged. Above the top side of the roller (1) open out at one end of the latter an inlet line (9) and at the other end an outlet line (10) for a stream of conveying air transporting the textile fibres in flock form. Obliquely set guide plates (11) are arranged above the top side of the roller (1) between the mouths of the inlet line (9) and of the outlet line (10). The guide plates (11) limit transfer chambers which move the stream of conveying air further in the direction of the axis of the roller (1). The transfer chambers are connected to an air-permeable and dust-permeable wall (30) which is provided on the right-hand side of the machine, as seen in the Figure, and which is part of a vacuum chamber (20). The machine can consequently separate out of the stream of fibre flocks not only coarser impurities through the bar grids (4, 5), but also fine dust-like impurities which are sucked through the air-permeable and dust-permeable wall (30) into the vacuum chamber (20) and then into the suction line (15). <IMAGE>

Abstract: It has been found that surface reactions with basic materials such as amines found in the processing environment during lithographic processing contribute to a loss of linewidth control for resists such as chemically amplified resists. This loss in linewidth results from the reaction of the acid generated by exposing reation with, for example, the amine resulting in a lack of chemical reaction where such reaction is desired. The problem is solved in one embodiment by employing an acid containing barrier layer on the resist.
