It is an object of the present invention to provide 2-iminocarboxylic acid derivatives, and a practically suitable industrial method for producing benzazepinones in a short process under mild conditions. In order to improve such an implant, the invention suggests that a sealing collar surrounding the recess opening, and an annular groove surrounding the sealing collar be provided on the top of the base body, wherein the post has a circumferential shoulder on the bottom thereof facing the base body, the shoulder having a shape that is complementary to the sealing collar and the annular groove. A valve core is also provided on the gauge through which fill air can be directed. The first crystalline silicon film and the second crystalline silicon film having different crystal structures are used as an active layer of a thin film transistor. The digital sigma-delta modulator generates a switching element control signal for controlling at least one of the switching elements. Preferably, a horizontal extension portion is connected to the riser rod at a location on the riser rod which is opposite to the horizontal transition portion.
