Novel DNA constructs and host cells comprising the same are disclosed. The plastic parts can be produced efficiently, in an automated manner which is flexible with respect to the process and workpiece and is operationally reliable. The implant container has a housing and a threadable cap with a vent hole formed therein which is covered by an insert member constructed of sintered PTFE mounted inside the cap. The column switch signal CL01 or CL11 makes conductive the corresponding column switches, and the selected bit line BL1, BL2, BL1, or BL2 is connected to a data bus DB or DB. The outer framework is formed by joining corresponding ends of sealing plates. Also provided is a process of producing a throw-type fire extinguisher.
