Abstract: The method it makes it possible for a system program automatically to form into a system program variant matching the storage capacity of the system memory during the loading into a system memory of a program-controlled processing device. For this purpose, the system program is subdivided into a basic program module and into at least one supplementary program module. A program loading sequence first initiates the storage of the basic program module and determines the available storage capacity. Depending on this capacity, the storage of program sequences of the supplementary program module is then enabled. The basic program module contains a list of branching addresses to the program sequences of the supplementary program module in which the addresses of the program sequences not loaded are modified. <IMAGE>

Abstract: A hand tool, in particular a percussion drill, has in its gear unit between drive motor (3) and driven tool (8) a wrap spring clutch (17, 21, 22), which either interrupts or restores the driving action, the two clutch halves of the wrap spring clutch (17, 21, 22) being of asymmetric design. The asymmetry may relate both to the geometry of the friction surfaces (17, 27) of the clutch hubs (18, 21) and to the shape of the wrap spring (23). Such a clutch can be adapted optimally to the respective intended application. In particular, according to choice, the ease of shifting can be increased, the range of variation of the initiating torque reduced or the power density changed. It is particularly advantageous to choose an approximately equal transferable torque on the two asymmetric clutch halves. <IMAGE>

Abstract: The device (1) for positioning elements, in particular car headlamps, comprises a stepping motor (12) driven by an order enabling a loss of step to be detected. Any loss of step, in the positioning phase, that is to say when a specified position is ordered, automatically guides the drive shaft of the element into a stop position in order that a reinitialisation be carried out by means of open-loop control electronics. After this reinitialisation or this recalibration, the specified positioning is attempted anew. The positioning error engendered by the loss of step, and which is consequenced each time the drive shaft comes up against a stop, is divided by virtue of a reduction i, so that the resulting error during positioning is always substantially less than 0.1 mm. <IMAGE>

Abstract: Le système décrit sert à répartir les moyens de traitement entre des terminaux (T1 ~ Tn) connectés par l'intermédiaire d'un réseau de communication (30). Chaque terminal (Ti) comporte au moins un groupe méthode (32) et une unité mémoire (34) servant à stocker les fichier de données. Un terminal émetteur, par exemple le terminal (T1) accède aux données se trouvant ailleurs dans le système réparti en générant un message. Ce message contient un code terminal qui identifie une fonction objet pour accéder à un terminal (T2) en vue d'exécuter une fonction objet, un code méthode qui identifie une méthode pour accéder aux données et un nom d'ordre qui contient ou identifie les données désirées. Le terminal, par exemple le terminal (T2), qui contient les données désirées, décode le message et accède à un fichier de données se trouvant dans l'unité mémoire (34) contenant les données désirées identifiées par le nom d'ordre. Ce message peut également contenir un sélecteur et des conditions de remise à l'état initial qui commandent la séquence de traitement des données dans les terminaux (T0 et Tn), de façon à ce que le traitement du terminal émetteur (T1) et du terminal d'accès aux données (T2) puissent être coordonnés. Lorsque le traitement identifié par le code méthode est terminé dans le terminal d'accès aux données (T2), un message contenant les données résultantes est émis depuis le terminal d'accès aux données (T2) en direction du terminal émetteur (T1). Les fonctions objets de la présente invention peuvent contenir une méthode sans données et peuvent être transmises d'un terminal à l'autre sous la forme de données. Ainsi, on peut remplacer ou créer n'importe quel programme du système d'exploitation ou d'application en transmettant une fonction objet contenant ce programme sous la forme de données.
