Patent EP-0651505-A1 (EP)
Inventor: ANGIULLI JOHN MICHAEL
IPC: H03K3/03
Filed: 1994-10-14
Abstract: A variable frequency digital ring oscillator which can be formed in a small area for use in testing of chips employs a ring oscillator formed of CMOS inverters (6), transmission gates (3,5) and capacitors (4,7) and CMOS logic as a voltage controlled ring oscillator. A wide range of frequency of oscillation is achieved with small number of components. The ring oscillator circuit's oscillator frequency is controlled only by DC voltages (V p ,V n ) such as may be provided by (but not limited to) a manufacturing chip tester. The output signal of the oscillator swings between Vdd and Vss and does not need additional level translation circuits to drive CMOS logic. The ring oscillator can be composed of an odd number of CMOS inverters connected in cascade to form a loop. We provide a CMOS transmission gate with PMOS and NMOS transistor device inserted between each adjacent inverter and a MOS capacitor connected between the output of each transmission gate and the Vss supply of the ring oscillator circuit (conventionally ground). The gate voltages of the PMOS and NMOS transistors in the transmission gate are different and provide a different DC voltage between Vdd and Vss. Variation of the gate voltages of the transmission gates controls the frequency of oscillation of the circuit. The use of a plurality of cascaded delay elements between inverters achieves a wider range of oscillation frequency than possible with a single delay element.

Abstract: A mechanism for connecting and disconnecting, locking and unlocking, and holding members (10,12) to one another, including snap-on fasteners, and at the same time providing mechanical, electromagnetic shielding, electrical conductivity, and thermal dissipation, coupled with environmental sealing, is provided by a cylindrical or elliptical body (12) having a circumferential groove (34) therein and a continuous coil spring (22) disposed therein. A housing (10), having a bore (36) sized to accommodate the cylindrical, or spherical, body (12), is provided, and a tapered bottom in the circumferential groove (34) prevents the spring (22) from turning past a vertical line, thus locking or connecting the cylindrical, or spherical, member (12) with the housing or plate (10).

Abstract: The invention relates to a process for the hydrometallurgical regeneration (reprocessing) of spent domestic and appliance batteries in order to recover the raw materials, in particular those containing metal. Said process comprises the fine powder, which is produced by the batteries being shredded and the residual materials being separated, being solubilised (digested) by means of a sulphuric acid and, in the process, at least a large proportion of the substances contained in the powder being brought into solution,  alkali being metered in to raise the pH, after at least one further process step the metallic raw materials being recovered from the metal salt solutions which have been produced selectively and in each case contain only one metal as the main component, and then the remaining sulphate solution, which is low in metal and contains salts, being worked up (processed) by a dialysis and the sulphuric acid recovered in the process and the alkali being fed back into the process cycle. So as to make it possible for the reagents in the form of the process acids and/or the process alkalis to be reused without difficulty, without the dialysis being impaired or the dialysis system being destroyed, and without premature wear of the anodes taking place in the electrolysis systems and without any emissions of ammonia taking place, the low-metal sulphate solution prior to the electrolysis is passed over an ion exchanger and all the residual metals present in the sulphate solution as cations are removed.

Abstract: A pearlescent lamp comprising a hollow glass envelope enclosing a source of electric light has its interior surface coated an iridescent optical interference film over which is disposed a layer of particulate titanium oxide, wherein both the iridescent film and titanium oxide layer have been formed in-situ inside the lamp envelope as a reaction product of gaseous TiCl₄ and H₂O. The iridescent film is first formed on the interior envelope surface and then an electrostatic potential is applied to the envelope which changes the reaction product to particulate titanium oxide which deposits on the interference film.

Abstract: L'invention concerne un procédé de formation d'un dispositif de mémoire vive à probabilités qui permet d'obtenir un comportement de sortie désiré en réponse à des entrées évaluées en temps réel. Dans une forme simplifiée de celui-ci, chaque entrée d'adresse du dispositif est amenée par un train d'impulsions ayant une longueur R égale à une première longueur R1, et le dispositif calcule une sortie en fonction des sorties d'impulsions produites par le dispositif en réponse aux impulsions des trains d'impulsions d'entrée. Le comportement du dispositif est évalué après avoir réalisé cette procédure au moins une fois, et à partir de celui-ci on obtient une mesure de la performance. Une nouvelle valeur de R = R2 « R1 est ensuite sélectionnée en fonction de la mesure de performance, et le processus est répété. Le contenu des adresses de mémoire dans le dispositif pRAM est mis à jour en fonction de la mesure de la performance qui vient d'être calculée. Le procédé peut s'appliquer à un réseau comprenant une pluralité de modules, chacun ayant un dispositif pRAM ou une pluralité de dispositifs pRAM.
