An improved design for a golf putter has a putter head with a back surface formed in an elliptical shape elongated along a transverse axis normal to a swing plane for the putter, enclosing a hollow interior and having a circumferential rim forming an elliptical frame for the putter head. During the formation of the upper capacitor plate in a capacitor structure, metals or their alloys are simultaneously patterned as an upper capacitor plate and as a fuse. The transformation engine accepts as input an implementation-independent model written in a modeling language such as UML that provides graphical notation to describe inheritable classes and their attributes and relationships. One or more upper guide rails substantially following at least a part of the surface conveyor’s outer circumference away from the suspension conveyor, therewith defining a gap between the surface conveyor and the upper guide rail or rails equipped to receive the saddles back portion. The antenna unit has a radio wave resonance part through which a radio wave is transmitted or received, an antenna ground part electrically connected to the radio wave resonance part, and a connection part which fixes the antenna ground part at such a position that the antenna ground part is closer to the radio wave resonance part than other ground parts of the wireless communication apparatus. 5 to 3 atom % of silicon, and at least 6 atom % of aluminum.
