  • Patent number: 6936303
    Abstract: The present invention provides an electric type initiator which can secure a reliability in activation and can be easily manufactured. The electric type initiator is characterized by comprising a header portion formed by using a resin material, a pair of conductive pins having top portions going through the header portion and exposing from an end portion of the header portion, a bridge wire formed by using a conductive body bridging between the top portions of the conductive pins, and a priming arranged in contact with the bridge wire. And, the present invention provides an initiator assembly which can be easily manufactured with less steps of the manufacturing process and can further reduce a manufacturing cost.

  • Patent number: 5725834
    Abstract: A candle type chemical oxygen generator which insures complete thermal decomposition of the candle with a predetermined flow rate of oxygen while maintaining the generator housing at a low temperature. Oxygen generated as a result of the thermal decomposition of the oxygen generating candle (32) by triggering the ignition device (F'), passes through cylindrical thermal insulation (36) and an annular gap between the cylindrical thermal insulation (36) and the cylindrical member (37) which houses the candle to thereby cool the cylindrical member, and is supplied to the exterior through the oxygen supply device (S').
