A method of producing axially hetero-structured nanowires is also provided.

At least one of the faces (14, 16) of the inventive ring magnet (10) is provided with an axial structure (20, 21, 22, 24, 26).

An axially hetero-structured nanowire includes a first segment that includes GaAs, and a second segment integral with the first that includes InxGa1-xAs.

An axial end of the winding structure is disposed adjacent the axial end of the filter element.

The polymeric abutment cap has a second anti-rotational structure for mating with the first anti-rotational structure and a second axial retention structure for mating with the first axial retention structure.

The upper region includes a first anti-rotational structure and a first axial retention structure.

Additionally, the structure allows an axial twisting of the backbone.

The on-off member (13) is provided with an axial guide structure.

The axial stop and the centering structure are different structures.

This reduces the number of different components and thus reduces costs, whilst achieving a high operating efficiency.

The invention relates to an electric fluid pump with a semi-axial construction, the pump housing (32, 33, 34) having at least two identical pump-housing parts (33, 34).

The channel structure may be open on a second axial end of the pole piece that is opposite the first axial end.

A method of producing axially hetero-structured nanowires is also provided.

The structure extends in the axial direction from the root to the distal end.

The first radial bearing structure is positioned between the axial bearing structure and the distal end of the main body of the drill head and is distally offset from the axial bearing structure.
