Patent EP-0787381-A1 (EP)
Inventor: DENT PAUL W
IPC: H03F3/60
Filed: 1995-10-10
Abstract: Circuit d'amplification de puissance conçu pour produire un signal de sortie s'appliquant à une charge et pouvant produire plus de deux puissances de sortie et comportant au moins deux amplificateurs présentant un rendement optimal quelle que soit la puissance de sortie. Ledit circuit peut fonctionner en différents modes dont celui consistant à activer un amplificateur pendant un cycle entier d'un signal d'entrée, à amplifier ou activer un amplificateur en fonction d'un signal de commande indépendant du signal de sortie amplifié. Dans les deux cas, les amplificateurs restants sont désactivés et le couplage entre les amplificateurs empêche les amplificateurs désactivés de freiner le flux de puissance allant de l'amplificateur activé à la charge. Selon un autre aspect de l'invention, le rendement optimal pour différents niveaux de puissance de sortie s'obtient en couplant chacun des amplificateurs à une alimentation commune et à la charge par l'intermédiaire d'un circuit d'adaptation d'impédance, avec une impédance différente pour chaque amplificateur. Le circuit d'adaptation des impédances peut comporter un transformateur push-pull muni de prises permettant de choisir différents rapports de spires entre les différents amplificateurs et la charge. Le circuit d'adaptation peut par ailleurs comporter plusieurs lignes quart d'onde reliées chacune par l'une de leurs extrémités à la charge, et par l'autre, à l'un des amplificateurs par l'intermédiaire d'un symétriseur.

Abstract: A video signal is sampled by sequential switches (104), etc. and the voltage held in capacitors (150) after passing through switches (110). Next, switches (120), (130) turn on, the hold for capacitor (152) is carried out, and that voltage buffered by analog buffer (170), then output. The switch on-off control is performed by means of lines L1 and L2. The control of the supply voltage is performed by V1 +  to V4 + , and the polarity of analog buffers (170) , (172), etc. is controlled. By means of the switch on-off control and the supply voltage control, four driving methods for alternating liquid crystal driving can be realized. Further, the analog buffers are composed of TFTs; and positive and negative polarity inversion can be performed through supply voltage shift.

Abstract: Un système (100) de distribution de produits multiples comprend une pluralité de distributeurs (10a, 10b, 10c) de solution d'emploi, ainsi qu'un dispositif de commande (110) destiné à sélectionner un des distributeurs (10a, 10b, 10c) selon un schéma prédéfini, par exemple, à sélectionner différents distributeurs sur différents jours de la semaine. Chaque distributeur (10a, 10b, 10c) distribue une concentration régulée de solution d'emploi à l'aide d'un appareil (13) d'apport de diluant, lequel délivre un diluant afin de former un concentré liquide à partir d'une composition chimique solide (22), et pour former du diluant d'appoint afin de diluer le concentré de liquide et de former une solution d'emploi d'une concentration régulée. Un réducteur (24) de mousse réduit l'énergie cinétique du diluant d'appoint avant le mélange avec le concentré liquide, afin de réduire la formation de mousse. Un utilisateur non qualifié peut faire fonctionner le système de distribution (10) afin de distribuer une solution d'emploi d'une concentratin régulée avec précision, et l'unité de commande (110) sélectionne automatiquement le distributeur approprié selon le schéma prédéfini, sans aucune entrée supplémentaire de la part de l'utilisateur. Par conséquent, la probabilité d'une erreur de manipulation de l'utilisateur se produisant est considérablement réduite par la sélection automatique du distributeur correct (10a, 10b, 10c), et la régulation de la concentration de la solution d'emploi.

Abstract: A semiconductor laser device comprises a plurality of distributed feedback semiconductor laser elements (2a,2b,2c,2d,2e) disposed on a semiconductor substrate (1) and each including a resonator (3) having a center axis and a gain-coupled diffraction grating (41), wherein the gain-coupled diffraction gratings (41) are arranged at the same period and in the same direction, and the center axes of the resonators (3) form different angles with the direction perpendicular to the direction of the diffraction gratings (41). Therefore, the wavelengths of light beams oscillated in the respective semiconductor laser elements are varied from each other. Further, even when the diffraction grating with no λ/4-shifted region is employed, the oscillation of laser light in each semiconductor laser element is not adversely affected by the phase change of the laser light due to reflections at the front and rear facets of the resonator, so that a stable single-mode oscillation is easily realized.

Abstract: There is disclosed a process for producing a glycidyl ester of acrylic acid or methacrylic acid which comprises the steps of neutralizing acrylic acid or methacrylic acid with a carbonate or a bicarbonate of an alkali metal in an excess amount of epichlorohydrin while an oxygen-containing gas is blown into the liquid reaction system; subjecting water formed by the neutralization and epichlorohydrin to azeotropic distillation to discharge them outside the reaction system and to form an alkali metal salt of acrylic acid or methacrylic acid; adding a quaternary ammonium salt as a catalyst to the reaction system to react the alkali metal salt of the acid with the epichlorohydrin and thus synthesize the glycidyl ester of the acid; cooling the liquid reaction product while recovering part of the excess epichlorohydrin under reduced pressure; adding aqueous solutuion of an alkali hydroxide to the liquid reaction product to separate into aqueous layer and organic layer; adding a catalyst deactivator to the organic phase; and subsequently distilling the organic layer to separate the glycidyl ester of the acid while blowing an oxygen-containing gas into the organic layer. The above process makes it possible to efficiently produce a highly pure glycidyl ester of acrylic acid or methacrylic acid in high yield with minimized contents of impurities.

Abstract: In a process of recovering oxygen-enriched gas by pressure swing adsorption with use of two adsorbers (A, B) each packed with an adsorbent which selectively adsorbs nitrogen from a gas mixture mainly containing nitrogen and oxygen, recovery of remaining oxygen-enriched gas is fully carried out by pressure equalization between both adsorbers (A, B), and a vacuum pump (8) is always connected to either adsorber (A or B) for continuous evacuation of nitrogen. For this purpose, the pressure equalization between both adsorbers (A, B) is conducted at least in two steps wherein one adsorber (A or B) is pressurized, whereas the other adsorber (B or A) is depressurized, so that recovery of oxygen-enriched gas is possible until there is substantially no pressure difference between both adsorbers (A, B).
