IPC: B22F7/00
Filed: 1982-09-08
Granted: 1986-02-05
Abstract: Lithographic printing substrate ordinarily require a mechanical or chemical graining of aluminum surfaces. Such substrates are difficult and expensive to make. It has been found that lithographically suitable substrate can be prepared by the firing of monobasic phosphate solutions with or without dispersed particles therein. The presence of reactive metallic oxides enhances the properties of the surface.

Granted: 1991-02-27
Abstract: Un circuit (10) reçoit un signal d'entrée cyclique possédant une fréquence déterminée par une source (11), cette fréquence pouvant varier, par exemple par rapport à un paramètre ou condition à mesurer. Le circuit (10) permet d'obtenir avec une grande précision un courant de sortie représentant la fréquence du signal d'entrée. En particulier, le circuit utilise une paire de tensions stabilisées et différentes (16) (17), l'une (16) desquelles est appliquée à un circuit d'établissement de moyenne (30) pendant un laps de temps prédéterminé pendant chaque cycle du signal d'entrée, et l'autre tension (17) est appliquée au circuit d'établissement de moyenne (30) pendant le temps où le premier signal n'est pas envoyé au circuit d'établissement de moyenne. Un signal de commande (Vo) qui est une fonction de la moyenne de la tension fournie par le circuit d'établissement de moyenne est développé à partir de celui-ci (30), et le signal de commande (Vo) est utilisé à son tour pour commander un amplificateur de commande de courant (60) et des transistors (61) (62) qui commandent à leur tour le passage de courant au travers d'une charge (40) reliée aux terminaux de sortie (36) (37) et au travers d'une résistance de réaction (63). L'utilisation de sources de tension stabilisée (16) (17) pour la dérivation de signaux de commande de courant assure une grande stabilité et permet de réduire le coût tout en obtenant un fonctionnement précis.

Patent EP-0153493-B1 (EP)
IPC: F02D41/12
Filed: 1984-12-22
Granted: 1989-03-29
Abstract: The invention is directed to a mixture metering arrangement for an internal combustion engine with a digital data processor, particularly a microcomputer, the signal processing pattern of which is governed by clock pulses, and with a signal generating means which delivers analog output signals. The signal generating means is responsive to operating parameters of the internal combustion engine and is an exhaust gas sensor responsive to the air ratio Lambda. The exhaust gas sensor is used in a closed-loop control system to influence the air-fuel ratio and changes its output quantity at the air ratio of Lambda=1. In this arrangement, a correcting stage corrects the influence of a delay time (tv) connected with the clocked signal processing on the mixture formation. The delay occurs in the transmission of the change in the output of the sensor. Two methods are indicated for the mode of operation of the correcting stage by means of which a mean value shift of the quantity (FR) influencing the mixture formation is avoided and the concentration of toxic substances in the exhaust gases is minimized. Flowcharts are disclosed to realize the invention by means of a suitably programmed microcomputer.

Abstract: 57 This invention is a method of color electrophotography in which toner images are superposed sequentially on a photosensitive material sheet to form a multi-color image by using a liquid developer. According to this method, the photosensitive material sheet is made to pass by a conductive doctor member and then by an air blasting member in sequence immediately after development, so as to form the multi-color image. By this method, the multi-color image can be formed in the condition that most of a excess developer is removed while a small quantity of carrier liquid containing no residual toner particles is made to exist as a uniform liquid layer on the surface of the photosensitive material sheet, and thus a clear image free from a fogging of the surface can be obtained.
