Abstract: Un procédé permet à une représentation d'une image, produite par juxtaposition de pixels noirs et blancs, d'être convertie en une représentation en tons continus. Selon ce procédé de conversion d'un affichage par juxtaposition de pixels, les zones dont la représentation est obtenue par une juxtaposition de points, sont comparées avec des sections de configurations à juxtaposition de points afin de déterminer une représentation appropriée en tons continus qui aurait pu produire l'image obtenue par juxtaposition de pixels. Ce procédé peut être répété sur un plan spatial, pixel par pixel, jusqu'à ce que la représentation initiale tout entière de l'image soit convertie en une représentation en tons continus. Le procédé peut aussi être modifié en ce qui concerne la technique produisant des élément linéaires. En outre, le procédé peut être utilisé pour effectuer des modifications de la grandeur de l'image, y compris des miniaturisations et des agrandissements de l'image originale. Selon cette application, des parties produites par juxtaposition de points de l'image originale sont à nouveau traitées par juxtaposition de points de façon à produire une image de sortie d'une grandeur différente. De même, des parties de l'image originale traitées selon la technique d'éléments linéaires sont traitées sous forme de valeurs d'échelle de gris et à nouveau traitées par juxtaposition de points pour produire des représentations d'éléments linéaires d'une grandeur différente.

Title: Explosive powder charge operated setting tool
Inventor: JOCHUM PETER
IPC: B25C1/14
Filed: 1994-04-14
Granted: 2000-06-13
Abstract: An explosive powder charge operated setting tool uses compressed propellant gases for returning a piston from an end position to a starting position. The piston is axially displaceable by the propellant gases within an axially extending guide bore in a piston guide. The propellant gases flow from the guide bore through a first opening into an axially extending channel outside the piston guide and then through a second opening in the region of the end position of the piston back to the guide bore. After the piston is driven into the end position, compressed propellant gases within the guide bore return the piston to the starting position where it impacts against the base of a cartridge carrier located at the starting position. When the piston is stopped, the cartridge carrier is displaced to a limited extent opposite to the setting direction of the tool. To afford the limited displacement, the cartridge carrier is connected to the housing part laterally enclosing the piston guide by sawtooth-shaped threads providing clearances.
