In some preferred embodiments of the present invention, a fastener on a door handle assembly having a door handle is moved by actuation of the door handle into a position in which the fastener connects the door handle assembly to the door. The germanium containing channel is coplanar with the plurality of source and drain regions, and the germanium containing channel includes a germanium containing material having a germanium content greater than the germanium content of the plurality of source and drain regions. The outer surface is formed at least in part by a lattice of protuberances at the same relative positional arrangement as the recesses. The thickness of the insertion layers is selected such that they do not increase the uniaxial anisotropy or deteriorate any other properties. Then, a requirement command is sent to the personal computer through the data transmission link, so as to control the personal computer to save the predetermined data. This process includes the step of conducting a hydrogenolysis of a halogenated trifluoroacetone, which is represented by the formula 1, by a hydrogen gas, in a liquid phase containing water, in the presence of a catalyst containing a transition metal, where X represents a chlorine, bromine or iodine, and n represents an integer from 1 to 3.
