A combination structure of the assembly plates and the cylinder of a lock latch includes a cylinder, a first assembly plate, and a second assembly plate. Further, requirements for improvements in productivity and cost minimization are also increased. A first cutter extends axially and radially from the distal portion, and includes a first blade for shaping an edge of a lens. The corrective impulses are filtered into shaped pulses that exhibit a constrained spectrum and combine with the communication signal to reduce an unwanted signal peak.
