According to one embodiment, this invention allows to acquire attribute information of a stream object and to generate it as management information upon recording a digital stream when an MPEG-TS that uses H. The method includes forming an etch film on a substrate, forming a protection film on the etch film, forming a hard mask layer on the protection film, and forming a plurality of first mask patterns characterized by a first pitch on the hard mask layer. A ground plane is mounted to the opposing surface of the main printed circuit board, in facing, spaced-apart parallel relationship with the antenna pattern and in spaced-apart parallel relationship with the main printed circuit board. The elongated prothesis is inserted in unexpanded state into a desired location within the body passageway and with the catheter positioned so that its expandable portion registers inside a first portion of the endoprosthesis, the inflatable portion of the catheter is inflated to cause deformation of the first portion of the endoprosthesis to an expanded diameter. The middle part of the wire clip extends through the plate cams and can be lifted away from the heat sink by turning the operating members from an unlocking state to a locking state. The forming step in which the starting materials are fabricated into a shape can include extrusion, dry pressing, or slurry casting.
