In a gas combustion type striking machine, a combustion chamber is opened and closed by moving a movable sleeve in a vertical direction. The present invention also relates to regulatory elements, promoters capable of causing expression of exogenous genes in plants, wherein the regulatory elements are from the genes for caffeic acid Omethyl transferase, 4CL, CCR or CAD. Then, the chemical formulation is pumped into SCF by a high-pressure pump 45 such that the SCF and the chemical formulation are mixed together to form a process fluid. Further, the associations in the speech signature database are leveraged to find other relevant mobile stations or users and to generate additional associations and to also locate associated users and mobile stations. The reinforced storage covers target the areas of the fabric storage covers that experience particular high stress and strain during deployment and filling.
