Abstract

Ensemble modulaire pour dispositifs de mémoire à bulles. Il comprend deux plaques 11 et 13 de réflexion thermiquement et électriquement conductrices comportant des fentes allongées parallèles 17, 19, 21 et 25, 27, 29 respectivement. Les éléments d'emmagasinage 15 sont placés entre les plaques. Des bobines 23 et 31 engendrant un champ magnétique sont associées aux plaques 11 et 13 respectivement, les fentes dans chacune des plaques étant parallèles à l'ouverture centrale pratiquée dans chaque bobine. Application aux mémoires à bulles magnétiques.
