Hydrophobins for stabilizing phases in biphasic liquid systems. The seal comprises at least one cover ring, made from a non-ferromagnetic material and at least one elastic first sealing lip, the first sealing lip is fixed to the cover ring and makes sealing contact with the encoder and at least one signal-active part of the encoder is arranged on the inside of the seal and rotates about the rotational axis with the hub. The slope is formed on a step portion 12 formed by a BM layer formed on at least one of a gate electrode, a drain electrode and a source electrode formed in a periphery of the pixel electrode or at least one of a gate wiring and a drain wiring formed in the periphery or a step portion formed by partially overlapping peripheral portions of the adjacent pixel color layers. The main housing defines a base conformed to self-support the main housing on a support surface with the dirt cup arranged with its open first end at a higher elevation than its closed second end. The second conductive polymer film is formed such that it covers the apertures of the plurality of pores formed in the anode conductor, and the first conductive polymer film is formed such that at least a portion thereof is disposed inside the plurality of pores, or it is arranged as an outermost film of the conductive polymer layer. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state.
