A signal input port of a reverse amplifier is provided by an FIC connector, for direct connection to an F-port output of a forward amplifier, thereby eliminating the need for jumper cables. Thus, the present invention provides an organic composite galvanized steel sheet that is formed by sequentially depositing on a surface of a steel sheet a galvanization layer, a zinc phosphate layer containing Mg, and an organic layer, and is characterized in that a value of MgP in the zinc phosphate layer is 0. Thereby, a driving displacement of the varifocal optical lens can be maximized. The connector can provide attachment between the insert and an external grille. An electronic thermal igniter assembly has an ignition component receivable through the opening in the lid so that the exothermic weld material may be ignited either by the electronic thermal igniter assembly or may be ignited by a spark.
