Abstract: The present invention is based on the finding that the previous column and row representation in the scanning image projection has to be given up, in order to enable that the ratio between row and column frequency or vertical and horizontal deflection frequency is not critical and may be decreased. An inventive projection apparatus for projecting an image on an image field includes a deflection means for deflecting a light beam about a first deflection axis at a first deflection frequency and about a second deflection axis at a second deflection frequency different from the first, in order to move the light beam across the image field, as well as a modulation means for modulating an intensity of the light beam depending on the image to be projected. The first and second deflection frequencies differ by less than an order of magnitude.

Abstract: A micromechanical device comprises a substrate and a member which is moveably attached to the substrate , wherein the member is formed in an electrically conductive layer, wherein a first area of the moveable member forms a first electrode, a second area of the moveable member forms a second electrode, and wherein the first electrode and the second electrode are electrically insulated from each other by an electrically insulating third area which penetrates the conductive layer, and wherein the substrate comprises a third electrode which is at least partially arranged opposed to the first electrode and the second electrode.

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.

Abstract: An apparatus for producing filaments from meltable material utilizing centrifugal force includes a hollow body (2) rotating at high speed, whose bottom (5) the meltable material strikes from above in the solid state. The wall of the hollow body, shaped as a cylindrical casing, is formed by a heating device (4) which includes metal elements running in a rectangular and helical fashion, such that the interstices of the helix form the discharge openings for the molten material.
