A method for manufacturing a semiconductor device includes forming a hard mask pattern and a spacer at both sides of the hard mask pattern. When the lens information obtaining unit obtains the updated lens information, the recording unit records the updated lens information in addition to the moving image data. The request may include a description of the alert area and other preferences or indications. The second portion provides a block connected to a tubular shaft for telescopically receiving the cylindrical rod. The invention furthermore relates to novel nucleic acid sequences which code for the \u03946-desaturases used in the method, gene constructs comprising these nucleic acid sequences, a vector and transgenic plants comprising at least one nucleic acid sequence or a gene construct.
