A plurality of the ignition devices are connected to an ignition control system via a common bus. The ignition devices are selectively operable for actuating a plurality of airbag devices by means of electrical energy and an electrical signal supplied from the ignition control system. Each ignition device includes an ignition package formed integrally from a communication/ignition circuit and an ignition element provided on a silicon chip. Not only can the dimensions of the ignition device be reduced in comparison with a case in which the communication/ignition circuit and the ignition element are separately provided, but also wiring between the communication/ignition circuit and the ignition element can be completed beforehand when the ignition device is produced, thereby decreasing the number of wiring steps during assembly with the ignition control system.

Ion-implanted bubble device comprises a magnetic layer in which bubble propagation paths are formed by ion-implantation. The bubble propagation path has an inside turn including a cusp of which the summit deviates toward a direction of bubble propagation with respect to a cusp center line. Such a bubble propagation path permits the ion-implanted bubble device adopting a folded minor loop organization to be realized.
