Abstract: A cutter insert for milling tools includes a base body having a base surface, a top surface, and four side surfaces. The four side surfaces, together with each of the base surface and the top surface, define respective cutting edges. The base body is twisted about each of two perpendicular, coplanar axes of the base body. Each side surface has two opposite corner edges that are offset from one another in a direction parallel to a center axis of the base body.

Abstract: The present invention relates to an apparatus and method for patterning a work piece arranged at an image plane and sensitive to electromagnetic radiation. Said apparatus comprising a source for emitting electromagnetic radiation directed onto a selected object plane, a computer-controlled reticle comprising a plurality of object pixels, adapted to receive said electromagnetic radiation at said selected object plane and being capable of relaying said electromagnetic radiation toward said work piece arranged at said image plane, an optical projection system comprising a Fourier filter adapted to filter said relayed radiation in a Fourier space and a first lens arrangement adapted to create essentially parallel central axis of cones of radiation onto said image plane, where every cone of radiation in a specific image pixel in said image plane corresponds to a specific object pixel in said computer-controlled reticle.

Abstract: A micromechanical component comprises a frame layer and an oscillating body which, with the aid of a suspension means, is supported in an opening penetrating the frame layer, in such a way that the oscillating body is adapted to be pivoted about an axis of oscillation vertically to the frame layer plane. At least one oscillating-body lateral surface, which extends substantially at right angles to the frame layer plane, is arranged in relation to at least one inner lateral surface of the opening in such a way that a capacitance formed therebetween is varied by an oscillation of the oscillating body in such a way that an oscillation of the oscillating body about the axis of oscillation can be generated by periodically varying a voltage applied between the frame layer and the oscillating body.
