IPC: H05K3/46
Filed: 1987-04-24
Abstract: PURPOSE:To obtain a conductor material which is chemically stable and has low resistance by adding tungsten or molybdenum as a main ingredient and group IIIa metal or group IIIa metal oxide as an auxiliary agent into the conductor material. CONSTITUTION:One or more species of tungsten or molybdenum as a main ingredient and group IIIa metal or group IIIa metal oxide as an auxiliary agent are added into a conductor material.

Resistance of the conductor material can be hence lowered. Further, a particle diameter of the group IIIa metal or the group IIIa metal oxide is made smaller than that of tungsten or molybdenum. Accordingly the group IIIa metal or the group IIIa metal oxide can be dispersed sufficiently into powder of tungsten or molybdenum.

Abstract: PURPOSE:To utilize to the utmost light absorbed in the vicinity of surface, and increase short current, by arranging PN junctions in the transversal direction on a semiconductor substrate, arranging alternately rows of N-type and P-type semiconductors, so as to intersect with the row of PN junctions, and forming ohmic electrodes on the N-type and the P-type semiconductors. CONSTITUTION:PN junctions are arranged in the transversal direction on a semiconductor substrate 1; the row 4 of N-type semiconductors and the row 5 of P-type semiconductors are alternately arranged, so as to intersect with the row of PN junctions; ohmic electrodes 6 are formed on the N-type and the P-type semiconductors 4, 5. That is, the following are arranged; an N-type gallium arsenide layer 2, a P-type gallium arsenide layer 3, a high concentration N-type gallium arsenide layer 4, a high concentration P-type gallium arsenide layer 5 and transparent ohmic electrodes 6. Thereby, electron-hole pairs generated by incident light absorbed in the vicinity of surface are specially separated. Since internal electric field is generated in the N-type gallium arsenide layer 2 and the P-type gallium arsenide layer 3, the lifetimes of electron and positive holes are lengthened. Since unevenness is generated on the surface, the reflectivity of the incident light is decreased, and the absorption coefficient is increased.

Patent MX-9207266-A (MX)
Inventor: ASSELINEAU LIONEL
IPC: C07C43/04
Filed: 1992-12-15
Abstract: A reactive distillation process is described, making it possible, in the same vessel, to carry out a catalytic reaction and to isolate the required product by distillation, in which the liquid phase containing the reactants passes from the top downwards through at least one catalyst bed without the vapour phase of the distillation passing through the said catalyst beds. These operating characteristics are in practice obtained in a reactive distillation zone (C) which comprises an alternation of distillation cells (D) comprising one or a number of trays (5) and of reaction cells (R) containing the catalyst beds and designed so that the liquid phase flowing off a distillation tray (5) flows over a spillway (7) via a down column (6) to reach the catalyst bed (8) at its bottom and to pass through it as an upward stream before pouring by overspill onto a distillation tray (5) of the following distillation cell (D), so that the distillation vapour which travels from the bottom upwards through the distillation trays (5) does not pass through the said reaction cells (R). Each reaction cell (R) is physically separated from the adjacent distillation cell(s) (D). The process and the apparatus which are described can be applied particularly to the reactions of synthesis of tertiary alkyl ethers by addition of aliphatic monoalcohols (methanol, ethanol) to isoolefins (isobutene, isopentene). <IMAGE>

Abstract: Un acumulador para formas comerciales que se inserta fácilmente en, o se separa de, una trayectoria de formato continuo, alimentándose las formas comerciales en zig zag desde una máquina para el manejo de formas comerciales (tal como un plegador) a otra (tal como una máquina postal como un insertador). Una barrera que tiene bandas impulsoras en una cara es movible desde una posición que permite que las formas posen debajo de ella, a una posición de barrera en la cual las formas se acoplan con la barrera y se impulsan lentamente hacia arriba a la barrera hasta que se flexionen por su propio peso o anaquel. Al manejar las formas de esta manera, las formas se doblan a lo largo de perforaciones entre las formas continuas (haciendo más fácil su separación subsecuente) y se evita que desarrolle un rizo.
