Title: Procede de developpement de vernis negatifs sensibles aux radiations
IPC: G03F7/32
Filed: 1985-07-08
Granted: 1991-04-10
Abstract: Procédé pour obtenir un solvant de développement pour des vernis négatifs sensibles au rayonnement utilisés dans des procédés lithographiques pour la production de puces électroniques. Le polymère de vernis négatif est appliqué sur la surface du substrat de la puce, directement ou grâce à une couche d'agent de liaison approprié, de n'importe quelle manière conventionnelle convenant à ce polymère particulier. Une fois obtenu le revêtement polymère de vernis sur le substrat, le polymère de vernis est irradié par l'utilisation d'une source de rayonnement convenable afin d'y obtenir une image latente. L'image latente existe dans le revêtement de vernis polymère sous la forme de polymère réticulé entouré par des zones de polymère non irradié et non réticulé qui doivent être retirés afin de développer l'image, produisant de la sorte le motif de vernis désiré sur le substrat. Le développement de l'image par voie humide nécessite l'utilisation de solvants capables de dissoudre le polymère non réticulé tout en laissant une image de polymère réticulé essentiellement non brouillée et non déformée sur le substrat. La présente invention prévoit l'utilisation d'un solvant de développement formé d'un mélange de composés organiques dont chacun, appliqué séparément, agit comme un non-solvant pour un tel polymère non réticulé, mais qui agit comme un solvant lorsqu'il est appliqué sous forme de mélange. Les images développées en utilisant les solvants de développement de la présente invention sont supérieures aux images produites en utilisant les procédés de développement de l'art antérieur du fait que sont essentiellement éliminés le gonflement, la déformation du profil, l'érosion superficielle et l'irrégularité des lignes de l'image développée.

Abstract: Familles d'hydroptères présentant un coefficient élevé de sustentation et un faible coefficient de traînée. Le vecteur de tourbillonnement induit est en partie supprimé par l'introduction d'une composante longitudinale d'écoulement orientée depuis la pointe du profil aérodynamique en direction de la base de l'hydroptère au moins dans la région de la pointe de ce dernier. On peut accroître encore l'efficacité de l'hydroptère en réduisant le tourbillon provoqué par un faible coefficient de sustentation et un coefficient élevé de traînée, par le renforcement de la surface le long de la pointe. Pour des conditions de sustentation données, il est possible de réduire la surface du profil aérodynamique et d'améliorer les performances de cavitation. On obtient une résistance élevée à la torsion et à la flexion par l'emploi de matériaux à modules élevés disposés selon des orientations sélectionnées.

Granted: 1991-01-09
Abstract: The processes for oxidation of propylene to acrolein and the oxidation of propylene to acrylic acid in two stages with acrolein as an intermediate are improved by use of anhydrous diluent gases to reduce or replace steam in the reaction streams. In particular, the use of anhydrous diluents which raise the composite flowing heat capacity of the diluent gas mixture to at least about 6.5 calories/gram-mole ( DEG C) will improve selectivity to desired products and will reduce the water load on the system. Reduction in second-stage catalyst efficiency is compensated for by introducing steam to the feed to the second stage, and/or by increasing the operating temperature of the second stage, and/or increasing the active surface area of the second/stage catalyst.

Title: Video signal processing for bandwidth reduction
IPC: H04N7/26
Filed: 1986-12-23
Granted: 1992-06-03
Abstract: At the transmitter a coder includes a motion vector generator (10) providing vectors (MV) describing the movement of individual blocks of pixels. The video signal is 4:1 compressed in bandwidth by pre-filters (13) and a sub-sampling unit (12) to produce a signal (SSH) from which a high-definition image can be re-constructed at (14) in the coder and at (14') in the decoder. The sampling lattice is shifted in accordance with the motion vectors (MV) which are digitally transmitted along with the compressed bandwidth analogue signal, to enable the samples to be correctly located in the reconstructed image. Poorly correlated moving areas are handled by pure spatial filtering (pre-filter (16) and sub-sampling unit (18)) with reconstruction (20, 20') by spatial interpolation. The two reconstructed signals (RVH and RVL) at the coder are compared in a mode selector (22) with the input video and a switch (24) is set to transmit whichever of the compressed signals (SSH, SSL) gives the best match. A mode signal is also transmitted and, at the receiver decoder this operates a switch (26) to select (RVH') or (RVL') correspondingly for feeding to the display. In a modified embodiment the sub-sampling unit (12) does not employ a moving lattice but all samples for a four field sequence are taken from one field of each sequence.

Abstract: A voltage generator (1) produces, without consuming power, an ideal network voltage (7), having an original amplitude, between the neutral conductor (N) and the control input of a transistorized symmetrical complementary circuit (2). The output of the complementary circuit is connected to the phase conductor (7) carrying the a.c. voltage produced. The power input connections (11, 12) of the complementary circuit are switched individually without interruption by an electronic switching circuit (3) to the different voltage levels of a d.c. voltage source (4) which is symmetrical to the neutral conductor. The control of the switching transistors in the switching circuit is effected by an electronic control circuit (5). By comparing in a set of comparators (28, 29) the positively and negatively-shifted instantaneous value of the d.c. voltage, the control is effected in such a manner that the voltages of the transistors (8, 9) of the complementary circuit (2) are inside specified voltage ranges. The system produces an a.c. voltage with a low source impedance and high efficiency.
