Disclosed is a static micromixer with a mixing chamber and a duct component upstream of the former for separate feeding to the mixing chamber of the fluids to be mixed or dispersed. The aim of the invention is to design the duct component in a static mixer of this generic type in such a way as to improve the efficiency of the mixing process in the mixing chamber. The invention is characterised by the following features: a) the wafer-like elements A and B for the duct component each consist of thin films with a thickness of 10-1000 microns, preferably

The invention relates to a micro-diaphragm pump consisting of two valve chambers, a pump chamber between them, each valve chamber being connected to the pump chamber by a channel, a pump drive and a diaphragm sealing the three chambers. The diaphragm has an inlet valve in the region of one valve chamber and an outlet valve in the region of the other. The aim of the invention is to design a pump in such a way that both valves may be fitted on the same side of the diaphragm and substantially to simplify the construction process of the pump body. For this purpose, the valves are integrated into the diaphragm and the valve component structures on the diaphragm are on the same side thereof, and a pump body containing the pump and valve chambers is made in one piece.

The invention relates to a process for producing microstructure bodies tapering as the height increases so that sieves or nets, for example, can be formed by galvanic shaping, the apertures of which are smaller on one side than on the other. The process of the invention comprises the usual steps in the X-ray deep lithography on an X-ray resist; in addition, the X-ray resist is subjected to a second irradiation over the entire surface in which the characteristic dose limit is not attained in the X-ray resist.

The invention concerns a method of significantly increasing the efficiency of a gyrotron and a gyrotron designed to carry out the method. Optimum matching of the gyrotron geometry and the magnetic field enables the overall efficiency to be increased if a slightly undulating magnetic field exists in the resonator zone and if the commutator is electrically biased or has coaxial electrically biased zones disposed adjacent to each other in the axial direction.

A process for accelerating electrically charged particles and a particle accelerator for applying the process are diclosed. The beam thus generated has a high degree of intensity and convergence and is suitable for uniformly depositing a material on a substrate. Similarly, it is useful for generating light of different spectral regions.

The invention relates to variant CD44 surface proteins. Antibodies against the variant determinant of these proteins and a process for producing them, and in addition the C-DNA sequences which code for these variant protein pieces, and the use of these proteins or parts thereof and the antibodies directed against them for the diagnosis and treatment of tumor metastases.
摘要:
A switch matrix comprises non-linear optical (e.g. bistable) elements each consisting of an optically active layer applied to a substrate (7). The surface of the substrate has a microstructure composed of pillars (2) each of which functions as a switch element and has at least one optically active layer (4). The pillar structure prevents interaction due to thermal contact and diffusion of charge carriers across the optically active layer and the substrate. The lithographic-galvanic (LIGA) process described is suited to the mass production of these structured substrates by moulding plastics. Both transparent and opaque substrates with high aspect ratios and adequate stability can be advantageously manufactured in this way.
