The invention relates to a method for manufacturing a plurality of metal microstructures characterised in that said method includes the following steps: a) obtaining a conductive substrate or an insulating substrate covered with a conductive seeding layer; b) applying a layer of photosensitive resin to the conductive portion of the substrate surface; c) flattening the surface of the layer of photosensitive resin to a desired thickness and / or surface state; d) irradiating the layer of resin through a mask defining the contour of the desired microstructure; e) dissolving the non-polymerised areas of the photosensitive resin layer to expose the conductive surface of the substrate at parts; f) galvanically depositing at least one layer of a metal from said conductive layer such as to form a block that substantially reaches the top surface of the photosensitive resin; g) flattening the resin and the electroformed metal in order to make the resin and the electroformed blocks level and thus to form electroformed parts or microstructures; h) separating the resin layer and the electrodeposited layer from the substrate; and i) removing the layer of photosensitive resin from the structure obtained at the end of step g) in order to release the microstructures thus formed.

The invention is directed towards an information presenting device and a portable electronic device including such an information presenting device. The information presenting device (16) comprises a first information layer (18) having a first information presentation structure (20) of photo chromatic material changing appearance when irradiated by light (28) of a specific wavelength, a second information layer (22) having a second information presentation structure (24), and a first light source (26) illuminating the second information layer for presenting the second information presentation structure, wherein the first information layer is of a material that is transparent for light emanating at least from the first light source when the first layer is not exposed to light of said specific wavelength.

The present invention provides a deinterleaver (10) for a wireless communication device that is simple and inexpensive to implement. In particular, a deinterleaver for deinterleaving a stream of data bits representing a plurality of symbols that have been interleaved using a multi-stage interleaving scheme is provided, the deinterleaver comprising preprocessing means (12) for ordering the data bits in the stream into pairs, such that the data bits in the pair are consecutive data bits from a symbol; at least one memory (16,18) for storing the paired bits, such that each pair of data bits is stored in a respective location in the memory; and a read and write address generator (20) for the at least one memory, the generator being adapted to determine the addresses in the at least one memorythat pairs of data bits are to be stored, and to determine the addresses in the at least one memory that pairs of data bits are to be read from.

A wind power generator having a nacelle, which is mounted to an upper end of a support tower, supports in rotary manner a rotor, and is oriented around a rotation axis by an orienting device provided with at least one gearmotor. The gearmotor presents an output gear coupled with a crown gear fixed to the support tower and is hinged to the nacelle so as to rotate around a fulcrum axis, which is substantially parallel to the rotation axis under the thrust of an actuation device.

An object of the present invention is to provide an apparatus for removing particles which effectively eliminates particles in the vacuum container unit without degrading the rate of operation of the processing device, and is simple and inexpensive to embody. <??>The apparatus for removing particles in accordance with the present invention is for a processing device including a vacuum container unit having a plurality of chambers in which a predetermined process is performed on a wafer carried in by a conveyer unit in atmosphere. The apparatus comprises a charge neutralizing means for neutralizing charges generated on a surface of the wafer, the charge neutralizing means being mounted in a waiting-accommodation unit which constitutes a part of the conveyer unit, and a charging means for adsorbing particles in the vacuum container unit by electrostatic force, the charging means being mounted in the vacuum container unit.
