Patent EP-0327636-A1 (EP)
Inventor: LEE NEVILLE K S
IPC: G11B11/105
Filed: 1988-08-08
Abstract: Un dispositif de mémoire de grande capacité optique est utilisé dans des systèmes de traitement de données. Deux ou plusieurs lasers produisent des rayons laser séparés de lecture et d'écriture ayant des longueurs d'onde différentes. Des rayons laser de lecture et d'écriture peuvent être polarisés orthogonalement. Un diviseur de faisceau de polarisation (30) combine les rayons de lecture et d'écriture le long d'un chemin optique commun sur une tête optique (12). La tête dirige le rayon combiné sur un support de stockage magnéto-optique (10). Un rayon de lecture est réfléchi par le support (10) sur le chemin commun au travers de la tête (12). Un diviseur de rayon dichroïque (32) disposé dans le chemin commun entre la tête (12) et le diviseur de polarisation (30) réfléchit le rayon de lecture sur un détecteur optique (18a, 18b, 20). S'il est nécessaire d'avoir plus d'un laser d'écriture, un second diviseur dichroïque (68) peut être utilisé pour combiner les rayons d'écriture multiples et les rayons de lecture.

Abstract: Cette invention se rapporte à une méthode de solidification et de stockage de déchet qui permet de conférer une très longue stabilité dans le temps, comparable à certains matériaux archéologiques, plus particulièrement aussi elle permet la solidification et le stockage de déchets qui sont dangereux ou potentiellement toxiques pour l'homme et l'environnement naturel. Le procédé de stabilisation, de solidification et de stockage de déchet, consiste: a) à préparer et mélanger ledit déchet avec un liant géopolymère silico-aluminate alcalin, dans des proportions telles que l'on obtienne un mélange contenant in-situ une matrice géopolymérique de type poly(sialate) (-Si-O-Al-O-) et/ou poly(sialate-siloxo) (-Si-O-Al-O-Si-O), et/ou poly(sialate-disiloxo) (-Si-O-Al-O-Si-O-Si-O), ladite matrice géopolymérique réalisant conjointement à la fois la stabilisation des éléments toxiques et la solidification en un matériau solide et durable; b) puis à traiter cedit mélange par les moyens conventionnels d'ingénierie afin d'obtenir un matériau stockable doté d'une stabilité dans le temps au moins équivalente à celles des matériaux archéologiques. Dans cette matrice géopolymérique, le rapport molaire des oxydes Al2O3:Na2O+K2O est compris entre 1,5 et 4,0, ces valeurs permettant de conférer une très longue stabilité dans le temps.
