Abstract: Longitudinal guides, as are used for example in sliding callipers, must satisfy a stringent requirement for straightness and stiffness. In order to guarantee high measurement accuracy, the slide (44) must be able to be guided along the bar (41) free of play and with a constant sliding resistance. Conventionally, guide tracks are arranged on opposite surfaces which results in a high production cost because of the requirements for their parallelity. The subject matter of the invention is a sliding guide which requires no parallel guide tracks and thus requires a low machining cost while providing high precision and being free of play. On the one hand, it contains a bar (41), which consists advantageously at least partially of ceramic, and, on the other hand, a slide (44), which is guided by two sliding surfaces in surfaces which are at an angle with respect to one another. The bar contains guide tracks and ferromagnetic rails (42) and the slide contains permanent magnets (47) which interact with the rails. In consequence, the slide is held on the bar by magnetic force and can be displaced without play over the complete bar length with a constant displacement force. <IMAGE>

Abstract: Un élément élastique tel qu'une plaque mince ou un ressort à disques, appelé communément ''ressort Belleville'', capable de flexion le long d'un axe perpendiculaire à sa surface, est modifié pour intégrer un segment d'amplification disposé dans une ouverture centrale sous forme d'une bande à profil approximatif de ''W'' (10) relié à ses extrémités à des positions opposées situées sur la marge interne de l'ouverture centrale. La partie centrale (11) du ''W'' forme un ''U'' inversé qui est soumis, après positionnement dans l'ouverture centrale, à un effort de torsion suivant le plan du matériau pour ramener légèrement les bouts de l'extrémité ouverte du ''U'' sur une position plus proche l'un de l'autre que les bords internes du ''U'' situés au plus proche de son extrémité fermée (12). L'un d'une paire de contacts est monté à l'extrémité fermée de la partie en forme de ''U'' du dispositif en face d'un autre contact (27) supporté par la base de l'interrupteur. Des forces (F) exercent une pression perpendiculaire au plan du matériau à un endroit du ressort sensible périphérique où les extrémités de la partie en forme de ''W'' se relient à la marge interne de l'ouverture centrale dudit ressort et, quand la pression atteint un niveau prédéterminé, la partie en forme de ''U'' se déclenche brusquement et se déplace vers une position où le contact qu'elle supporte est en opposition au contact porté par le boîtier d'interrupteur.

Abstract: Des modules (MD) disposés sur une puce (CH) et qui sont accessibles uniquement à partir des éléments de raccordement (EXT) du composant (CH) sont testés au moyen de configurations d'essai qui sont produites pour les modules (MD). Pour l'essai, ces configurations de test de modules (MTM) sont transformées en configurations d'essai (BTM) qui sont appliquées aux éléments de raccordement (EXT) du composant (CH) et sont telles que les configurations de test de modules (MTM) interviennent alors au niveau des éléments de raccordement (INT) des modules (MD). La transformation s'effectue au niveau de fonctions de transmission (UF) qui représentent les chemins de connexion entre les éléments de raccordement (EXT) du composant et les éléments de raccordement (INT) des modules (MD). Les configurations de test de modules (MTM) sont converties au moyen de ces fonctions de transmission en configurations de test de composant (BTM) qui peuvent alors être appliquées aux éléments de raccordement des composants. L'accès aux éléments de raccordement des modules (MD) n'est plus nécessaire. Les modules (MD) sont des circuits, par exemple des additionneurs ou des multiplicateurs, etc., pour lesquels existent déjà des configurations de test. Les réseaux suivis par les chemins de connexion entre les éléments de raccordement des composants et les éléments de raccordement des modules sont constitués d'éléments de circuits qui n'altèrent pas la logique des signaux transmis aux éléments de raccordement des composants pendant le transit jusqu'aux éléments de raccordement des modules.
