摘要： An igniter assembly having excellent moisture proof is provided. A cylindrical protruding portion 24 and a cylindrical stepped portion 25 are arranged in the metal collar 20. Shrinkage of a resin 30 after injection-molding produces a gap in an interface 50 but, to the contrary, in an interface 51, it presses the cylindrical stepped portion 25 and does not produce a gap. Thereby, since production of a continuous gap is prevented, entry of moisture is prevented.

摘要： A method for determining the charging capacitance of a capacitor in an air-bag system using a bus system. The charging capacitance of a capacitor required to normally operate an air-bag system is determined by the formula (I) below. C = 2E/V2 (I) [where C is the charging capacitance of the capacitor, V is the charging voltage, and E is the minimum ignition energy needed to heat the heating part of an igniter and thereby to ignite the igniter powder and given by the formula (II) below. E = Imin2×(Rmax + r1 + r2) × T + w × 10 (II) [Imin: the minimum ignition current value (A), Rmax: the maximum resistance value (Ω) of the heating part, r1: ON-resistance value (Ω) of the switching circuit (the maximum ON-resistance value at 150°C), r2: the resistance value (Ω) of another element, T: the time (μsec) when current flows through the heating part, w: the power consumed by the whole integrated circuit when the switching circuit is OFF.
