The present invention is directed to novel telomerase nucleic acids and amino acids. In a first rotation direction of the drive shaft, each motorized member is driven in a forward direction, and each pumping propeller generates the flow of liquid in the normal direction ensuring the cleaning of the immersed surface. The earth plane suitably comprises a silicon layer which is doped so that it has become conductive and can thereby constitute the earth plane for the transistor and the additional component of chip type.
