A method of producing a flexible timing-driven routing tree is provided. It is thus possible to repair more defective addresses for a given number of redundant memory cells. One end of the heat pipe is thermally attached to the fin unit, and the other end of the heat pipe is thermally attached to the first surface of the block. Each module and stator core segment can be individually installed and removed without disturbing the other units. The method can include digitizing a signal modulated by a pseudo noise sequence, dividing the digitized signal into a plurality of sample blocks, and estimating a PN phase embedded in a sample block of the plurality of sample blocks using an iterative message passing algorithm executed on a redundant graphical model. This arrangement facilitates the centering and fastening of any tool to the press machine.
