    • Closing movement of at least one of two or more air chambers is started at an early stage, and an inflated air chamber is tightly closed and maintained in an inflated state for a long time. Inside of an airbag is partitioned into air chambers, with a partitioning cloth, and a diffuser that stores a gas generator is disposed in the air chambers, through the partitioning cloth. Gas from a gas generator is rectified by the diffuser, and is supplied from outlet parts, into the air chambers, thereby inflating and deploying the air chambers. An occupant side base cloth, a semi-perimeter portion around the lower outlet part, is connected to a back-side base cloth of the airbag, and in accordance with an inflation of the lower air chamber, a tension is imposed on the occupant side base cloth from the back-side base cloth, thereby elongating the lower air chamber. This causes the base cloths to come close to each other and gradually narrow the opening width, thereby enabling the base cloths to closely stick to each other so as to close the opening of the lower outlet part.

    • A differential transformer includes a primary coil for excitation and first and second secondary coils for detection which can be wound up on an outer surface of a bobbin made of a non-magnetic substance. In the bobbin, i.e., in a differential coil composed of the primary coil and the first and second secondary coils, a core is movably inserted in an axial direction thereof and is made of a magnetic substance. In the differential transformer, when AC current is applied on the primary coil, an induced voltage corresponding to a relative displacement between the core and the differential coil is generated, so that a size of a measured member can be measured by detecting the induced voltage. In the first and second secondary coils, a compound conducting wire is used, which includes two conducting wires which are different from each other in forms of a thermal coefficient of resistivity and are connected by a predetermined rate with regard to their length. Therefore, it is provided that the differential transformer can obtain a detection value corresponding to the relative displacement between the core and the differential coil regardless of a change of the ambient temperature.

    • A switching power supply capable of executing output voltage stabilizing control with a high degree of reliability even when the DC output voltage is at DC 2V or lower. A DC--DC converter unit 1 converts a DC input voltage Vin to DC through switching and outputs a DC output voltage Vo for a load 10 through output lines 71 and 72. An auxiliary power unit 3, which is electrically linked to the DC--DC converter unit 1, outputs a DC voltage Va through an auxiliary source output line 30 having a potential that is negative relative to the potential at the lower-potential output line 72. An output voltage detection unit 2, connected between the higher-potential output line 71 and the auxiliary source output line 30, detects a DC voltage (Vo+Va) manifesting between them and provides the detection signal to a control unit 4 via a photocoupler 9. The control unit 4 implements output voltage stabilizing control on the DC--DC converter unit 1.
