A method and system for enhancing reach-performance of a multi-carrier VDSL System estimates loop length, estimates maximum available bandwidth that can be utilized at that particular loop length, optimally selects an FFT size and sampling rate, and decides whether to apply a time domain equalization to its receiver and if so, selects a cyclic extension size. more than the maximum temperature of a first reaction temperature range. Distribution mechanisms are mounted movably on the shell between a rest position in which they prevent the fluid from coming out of the shell and an active position in which they allow the fluid to come out when the user presses his hands against them during washing. The IC carrier is held, adhered to the oversheet left in the recess. The controller moves the movable unit at a decelerated, low rate of speed before finishing its movement to the first position. Alternatively, a source gas is supplied to the interior of a chamber between a substrate and a copper plate member such that the source gas is gradually increased continuously from a flow rate of 0 to a predetermined flow rate to increase the particle size of the metal component, as copper gradually.
