A new and distinct apricot variety, Prunus armeniaca cv. The retainer and the inner and outer rollers not hardened are assembled together with rollers into a bearing and thereafter the assembled bearing is carburized, hardened and tempered. Read and write pointers are provided to designate which of said frame buffers that are used to be readwrite accessed at each point in time. These living polymer radicals can be further reacted to form polymers with a controlled architecture. The light-emitting unit is moved in the thickness direction of the object by a moving member so that the light-emitting unit can radiate the coherent light in a different radiation range in the thickness direction at the edge of the object. The 3-D, 2-D, and 1-D information is utilized to determine the thickness, surface area, volume, and mass of the organ wall.
