In a method of producing a conductor pattern on a substrate and, in particular, of producing RFID labels, the conductive base material and the substrate material are initially provided, further the conductive base material is punched to obtain a conductor pattern and a residual base material. The at least one operation may involve, at least in part, at least one object stored in the storage. The transitioning passage includes at least two turning corners of obtuse angle at the outermost turning side and adjacent to the horizontal channel and the vertical channel, respectively. The handle has a main body and a chamber disposed within the main body. Further, the present invention is: a hydride composite containing NaH, a metal salt containing an alkali earth metal or a transition metal, and an ammonia source that is a solid at ordinary temperatures and generates an ammonia gas by decomposition; and a preparation process of a hydrogen gas including a reaction process to heat such a hydride composite. The methods can be used for detecting, imaging andor treating pathologies, as well as for diagnostics.
