Patent EP-0359809-A1 (EP)
Inventor: ZURAWSKI JOHN HENRY
IPC: G06F7/00
Filed: 1989-03-30
Abstract: Un procédé et un appareil servent à prévoir le nombre de bits qui doivent être pris en considération afin de normaliser le résultat d'une addition ou d'une soustraction à virgule flottante. Ils utilisent un additionneur/soustracteur (34) à virgule flottante de basse précision, un codeur de priorité (23) que détermine la position du bit non-zéro le plus significatif afin de générer la quantité de normalisation et une logique de pré-arrondi (18) qui pré-décale un bit d'arrondi en sens opposé à la normalisation. Le procédé et l'appareil fonctionnent en parallèle avec un additionneur (33) à virgule flottante de haute précision, ce qui rend superflus dans la plupart des cas un calcul de précision absolue de normalisation de la virgule flottante et un calcul d'arrondi. La quantité de normalisation requise pour une addition/soustraction à virgule flottante de basse précision est calculée avant le début de l'étape d'addition/soustraction à virgule flottante de haute précision. En outre, la logique de pré-arrondi fournit un bit de report à l'additionneur/soustracteur de précision absolue, ce qui économise le temps associé à une addition de bit d'arrondi de précision absolue.

Abstract: The present invention relates to an apparatus and method for safe disposal of hypodermic syringes, needles and other small, contaminated instruments such as, for example, scalpel blades, stitch cutters etc. (commonly referred to as "sharps"). The apparatus firstly comprises a collection container (30) having a primary lid (31) which is movable between an open position and a closed position, and is releasably latched in the closed position. The latch mechanism (34) is adapted to be released when the container is brought into cooperation with a destructor apparatus (10). The destructor apparatus comprises a disposal receptacle (55) adapted to receive the container and unlatch the lid, and a destructor means (20, 13, 14) adapted to generally comminute the materials deposited therein. The destructor apparatus has an inlet (15) and an outlet (16), a plurality of rotating blades (20) which cooperate with two cutting plates (13, 14) which are arranged to define a flow path for the materials between the inlet and the outlet. The cutting blades and cutting plates cooperate to comminute the material by impact and cutting action. The present invention provides a convenient means of disposing of sharps generally without risk to the person handling the sharps.

Abstract: A motor vehicle clutch control for vehicles which are equipped with manual transmissions. The control has multiple hydraulic actuators which are mounted on a conventional stationary bell shaped housing which encloses a clutch. The actuators are positioned apart from the axis of the clutch and act directly on a member which is centered on the rotational axis of the clutch. The bell shaped housing has apertures which cooperate with the "off axis" mounting of the actuators to allow the inspection and the servicing of the actuators without the removal of the bell housing or other adjacent parts from a vehicle. In a first embodiment of the invention, the actuators are mounted on a detachable bracket in the interior of the housing and are accessible for installation and removal through an aperture in the side of the housing. In the second embodiment of the invention the actuators are mounted on the rear of the housing and have output members which extend through apertures in the rear of the housing. The "off axis" mounting cooperates with the apertures to allow their installation and removal from the housing.

Abstract: A method of forming a compound semiconductor (GaAs) layer hetero-epitaxially grown on a silicon single crystal substrate(1) comprises the consecutive steps of: 
growing a first (e.g., III-V group) compound semiconductor (GaAs) layer(3) on the silicon substrate(1); heat treating the substrate and the layer to reduce a dislocation density thereof; doping the first compound semiconductor (GaAs) layer(3) with p-type impurities by feeding the impurities together with a volatile group element (V group) source gas (AsH₃ gas) into a reactor during the heat treating step; and growing a second compound semiconductor (GaAs) layer(4) on the first compound semiconductor (GaAs) layer(3). It is possible to adopt an ion-implantation method instead of the thermal diffusion method. A GaAs/Si substrate in which an increase of electron carriers is prevented by a compensation with the doped p-type impurities is obtained and is used for a production of a GaAs device (FET).

Abstract: On incorpore communément des composés d'hydroxylamine dans des solutions de développement photographique en couleur, afin de retarder l'oxydation due à l'air. Lorsque l'élément photographique traité dans la solution de développement en couleur contient un composé polyhydroxy aromatique servant de supplément stabilisant, il se produit une élévation du niveau dudit composé dans la solution de développement lorsqu'un vieillissement se produit. De plus, du fait du vieillissement, il se produit une élévation graduelle du niveau des impuretés métalliques à l'état de traces dans la solution. L'interaction d'une impureté métallique à l'état de trace avec le composé polyhydroxy aromatique peut former un complexe métallique lequel catalyse l'oxydation du composé d'hydroxylamine, et le rend ainsi inefficace pour l'utilisation à laquelle il est destiné. Selon le procédé amélioré de l'invention, la solution de développement couleur est protégée contre l'oxydation catalysée indésirable due à un complexe métallique, par adjonction dans ladite solution d'un complexant d'acide aminopolycarboxylique.
