Abstract: Des procédés et des appareils permettent de détecter des réactions immunochiniques et des niveaux d'antigènes et d'anticorps contenus dans du sérum. Un réactif immunochimique sélectionné est immobilisé sur la surface d'une première électrode. Une deuxième électrode est agencée de sorte que les électrodes génèrent un courant galvanique lorsqu'elles sont électriquement interconnectées et submergées dans une solution aqueuse conductrice. Les électrodes sont ensuite électriquement interconnectées et submergées dans une solution aqueuse conductrice qui contient le réactif immunochimique complémentaire du réactif immunochimique immobilisé. Le courant galvanique généré par les électrodes submergées est mesuré en fonction du temps. Le niveau du réactif immunochimique complémentaire contenu dans la solution est calculé en comparant le courant mesuré avec un courant standard.

Abstract: Lorsque des programmes écrits pour des ordinateurs Von Neumann peuvent être utilisés sur des ordinateurs géants, par exemple des ordinateurs vectoriels, les opérations du programme qui peuvent être exécutées en parallèle doivent être exécutées en parallèle dans les ordinateurs vectoriels afin d'exploiter la capacité de ces derniers. Ces situations peuvent alors être introduites dans le programme s'il contient des boucles de programme. Une boucle de programme qui ne renferme aucun cycle peut être vectorisée, c'est-à-dire, exécutée par des instructions vectorielles. Si une boucle de programme comporte des cycles, l'ordinateur vectoriel doit comporter des instructions spéciales pour exécuter ces cyles en parallèle. Une instruction spéciale de ce type peut, par exemple, être une instruction pour former la somme vectorielle ou pour former une série arithmétique. Les boucles d'instruction sont l'objet d'un contrôle pour y déceler la présence éventuelle de cycles qui peuvent être remplacés par des instructions spéciales. A cet effet, le flux de contrôle et le flux de données déterminés par les instructions dans la boucle sont analysés et des corrélations de contrôle et des corrélations de données entre les occurrences scalaires de variables dans les instructions sont déterminées et tracées sur un graphique. On analyse ensuite soigneusement ce graphique pour déterminer si un cycle qu'il contient peut être remplacé par une instruction vectorielle de l'ordinateur vectoriel.

Abstract: La présente invention est conçue pour fonctionner avec un dispositif d'imagerie numérique qui reproduit sur papier une image originale en couleur. De manière à obtenir des reproductions de haute qualité, c'est-à-dire des reproductions qui correspondent du point de vue de la finition couleur à la couleur de l'image originale, le procédé de la présente invention travaille sur les densités de couleur originale avec un module de correction des couleurs qui possède, comme entrées, les densités désirées de rouge, vert et bleu, et qui sort les densités modifiées de rouge, vert et bleu que l'on peut considérer comme étant des signaux de commande cible indépendants du canal pour le dispositif d'imagerie. Dans le cas où les conditions extérieures changent et empêchent d'obtenir les densités désirées de rouge, vert et bleu lorsque le module de correction de couleur est utilisé, un module d'ajustement neutre est activé qui prend comme entrées les signaux de commande cible de rouge, vert et bleu du module de correction de couleur et sort des signaux ajustés de rouge, vert et bleu qui sont envoyés au dispositif d'imagerie. La dérivation des paramètres pour le module d'ajustement neutre s'effectue par la production d'une image sur papier de taches de couleur neutre. Les densités des taches sont mesurées et fournies au module de correction de couleur pour déterminer les relations correctes entre les signaux de rouge, vert et bleu sortant du module de correction de couleur et les densités résultantes. Dans un mode préférentiel de réalisation de l'invention, le module d'ajustement neutre est constitué de trois tables de consultation unidimensionnelles. Le module de correction de couleur est constitué de deux fonctions polynomes, de deux ensembles de trois tables de consultation unidimensionnelles et d'un réseau de circuit qui assure les fonctions d'exponentiation et logarithmiques.

Date Jan. 10, 1991.A known film becomes transparent when heated from a first temperature (for example, room temperature) to a second temperature and non-transparent when heated to a third temperature. These changes are reversible. A film of this type is to be used as a record carrier for optical information. The film (A) is passed continuously or stepwise past an erasing device (L), a cooling device (K), a preheating device (V) and a writing device (S). The film (A) can be made either transparent or non-transparent by heating it to different predetermined temperatures. The information can be recorded on the film in either its transparent form in non-transparent surroundings or in its non-transparent form in transparent surroundings. The device can be used together with the film to obtain a "paperless" office, because the recordings can be erased from the films, which can therefore be constantly re-used.

Abstract: An alignment detection apparatus for detecting the alignment of a superfine exposure system including an interrupted emission light source. The apparatus is equipped with an output variation monitoring sensor to detect an output variation of the light source and further a photoelectric conversion device to perform the photoelectric conversion of the alignment light to generate discrete photoelectric conversion signals. Also included in the apparatus is an integration and hold circuit to integrate and peak-hold each of the photoelectric conversion signals. This peak-hold values are corrected on the basis of the detected light-source output variation due to the monitoring sensor to output stepwise continuous signals from which a harmonic component is removed by a filter so as to obtain a smooth analog waveform. This analog waveform is processed by a phase detector. The output of the phase detector allows an accurate alignment irrespective of using the interrupted emission light source.

Abstract: A multistep process is disclosed which enables hermetically sealed, durable, long-lasting illumination devices which utilize electrical discharges through inert gas and inert gas/mercury vapor mixtures to be produced in an essentially flat-plate configuration without the use of glass tubing to contain the discharge. This process utilizes plates of glass having a particular range of thermal expansion coefficients for the preparation of these display devices through the discovery of a heating/cooling process that enables these thick glass assemblies to be produced rapidly yet without cracking and without significant residual air or water vapor contamination and which includes the heat sealing of a evacuation/backfilling tubulation in the same sequene and also includes the unique feature of the inclusion of finely divided powder in the inert gas chamber which, when subjected to the heating/cooling cycle, acts to getter residual air and water vapor from the inert gas. This process also utilizes a special means for preventing the adhesion of the flat plates to the platens used for their support during the thermal fusing treatment that is required to form the gas discharge channels. An interrupt step, introduced after fusion bonding is complete, enables the usage of a low softening point glass having a thermal expansion coefficient compatible with that of the window glass to produce the evacuation and gas filling tubulation port.
