According to some embodiments, an arrangement of buffers in memory banks is provided. Each noise generator is positioned so as to convert a laminar or transitional air stream into a turbulent air stream such that a turbulent air-fuel mixture is realized in the combustion section of the engine to achieve more efficient operation. The sensor assembly is fixedly attached to the laser nozzle assembly and moves with the laser nozzle assembly. A first insulation layer is interposed between the first storage gate and the sidewall of the fin, and a second insulation layer is interposed between the second storage gate and the top surface of the fin. The mounting member has a planar surface section at one proximal-end-surface side of the cylindrical outer-peripheral surface. The post, which is disposed perpendicularly between the receptacle member and the clasp member, is formed from first and second post formation means having engaged one another when the resilient arm is inserted in the sleeve.
