Abstract:
L'invention se rapporte à un procédé de fabrication d'une pièce de micromécanique (11, 21, 31, 41, 51, 61) en un matériau monobloc. Le procédé comporte les étapes suivantes : a) former un substrat (1) comportant l'empreinte (3) négative de ladite pièce de micromécanique à fabriquer; b) recouvrir ladite empreinte négative du substrat (1) d'une couche (5) d'un matériau; c) retirer du substrat (1) une épaisseur supérieure (e 2 ) à celle (e 1 ) de la couche déposée (5) afin de laisser une épaisseur de ladite couche circonscrite dans ladite empreinte négative; d) retirer le substrat (1) afin de laisser libre la pièce de micromécanique (11, 21, 31, 41, 51, 61) formée dans ladite empreinte négative.
Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen von Körpern mit Oberflächenstrukturen im Mikrometer- oder Nanometerbereich, wobei der Prägeabschnitt eines Prägewerkzeugs mittels eines Härteprüfgeräts mehrfach auf verschiedene Stellen der Oberfläche eines Körpers gepresst wird, wodurch an den jeweiligen Aufpressstellen Vertiefungen eingeprägt werden, und wobei ein Prägewerkzeug mit einem länglich geformten Prägeabschnitt eingesetzt und entsprechende Kanäle oder linienartige Strukturen in dem Körper erzeugt werden.
Abstract:
PURPOSE: A mold for an electric fabrication and a method for manufacturing thereof are provided to reduce peeling phenomenon at a bonding layer of a conductive layer using silicon. CONSTITUTION: A mold for an electric fabrication includes next steps. A substrate is supplied. An upper layer(21') of substrate is etched to one or more patterns to an intermediate layer(22') in order to one or more cavity on a mold. The upper portion of substrate is coated with electrically insulating coating. Coating and intermediate layer is formed on a vertical wall(31') by directionally etching. The substrate has an upper layer(21') and a sub-layer(23').
Abstract:
A micromechanical structure has a first micromechanical element, a second micromechanical element and a torsion spring arrangement having a first torsion spring element, having a first center line, mechanically connected to the first micromechanical element at a first contact region and to the second micromechanical element at a second contact region, and having a second torsion spring element, having a second center line, mechanically connected to the first micromechanical member at a third contact region and to the second micromechanical member at a fourth contact region in order to connect the first micromechanical member and the second micromechanical member to be movable relative to each other. A distance between the first and second center lines, starting from the first and third contact regions toward the second and fourth contact regions, decreases in a first portion and increases in a second portion. In a rest position of the micromechanical structure, the first and second torsion spring elements are arranged without contact to each other.
Abstract:
The invention relates to a microelectromechanical system (10) comprising a drive module (200) comprising:
a fixed drive portion (210), a movable drive portion (220), and a suspension (230),
the movable drive portion (220) being able to be moved relative to the fixed drive portion (210) in a first direction (A), as a result of an electrostatic force, which causes an elastic deformation of the suspension (230), and the movable drive portion (220) being able to be moved relative to the fixed drive portion (210) in a second direction (B), opposite to the first direction (A), as a result of an elastic return force generated by the suspension (230),
the actuator (11) also comprising a stop (24) limiting the movement of the first movable portion (220) in the second direction (B) so that the elastic force generated by the suspension (230) is not cancelled.
Abstract:
The invention relates to a one-piece metal component including an electroformed metal body, the external surface of the body including, only over or to a predetermined depth, less trapped hydrogen than the rest of the electroformed metal body causing a hardening relative to the rest of the body in order to improve the wear resistance of the one-piece component while preserving a relative magnetic permeability of less than 10 and the ability to be driven or pressed fit.
