An electric actuator for an automatic transmission includes an adapter to transmit rotary motion between the adapter and the automatic transmission. The substrate is made of a metal foil processed into a three-dimensional structure which is substantially deformed from a major plane of the metal foil, preferably having bulge portions which protrude from at least one side of the metal foil, the bulge portions preferably having a curved, strip-shaped form between laterally spaced slits in the metal foil. The gene is controlled by the promoter for the catalytic subunit of the telomerase or by the promoter for cyclin A. The nitride semiconductor layer is provided on the single crystal layer. In this case, a discharge vessel plate 1, 9 is, as it were, of two-fold design, specifically as a first discharge vessel plate 1 with an external electrode set and, in addition, as a stabilizing plate 9 outside the first discharge vessel plate 1. The markers are shaped and located at the stent end such that the compressive stress exerted on the end annulus of the stent during release of the stent is shared between the markers and the inflection zones that do not carry a marker.
