Abstract: A first valve chest 241 formed integrally with a lid 2 of a high-pressure gas cylinder, a first valve element 5, a spring 6, a second valve chest 32, a second valve element 7, a spring 8 and a main body 8 are all formed in a rotor-shape, and in addition to arranging their axis lines on the same axis lime, flow channels 56, 35 and 76 are arranged on said axis line. By forming each part in a rotor-shape and adjusting the vibration directions of the valve elements 5 and 7 to the same direction, miniaturization is contemplated while suppressing loads generated by vibration. This invention is to provide a compact two-step pressure-reducing valve usable for a long term.

Abstract: An airbag device for a vehicle includes an airbag that can be inflated to restrain an occupant of the vehicle against the impact of a collision, an inflator for generating gas to inflate the airbag, and a guide passage provided between the inflator and the airbag for guiding the gas into the airbag. The airbag has at least one opening formed therein to provide a fluid communication between the interior and exterior of the airbag, the opening being disposed near the guide passage to perform an aspiratory function efficiently.

Abstract: A folded-up air bag is accommodated in a module cover of a steering wheel, and a peripheral edge of an opening in the air bag is fixed to a retainer supporting an inflator. The folded-up air bag is covered from a rear side of a vehicle to a front side of the vehicle by a deployment-limiting sheet disposed along an inner surface of the module cover and fixed at one end thereof to the retainer. The deployment-limiting sheet is longer than a length of an inner periphery of the module cover in a longitudinal direction of the vehicle body. Thus, it is possible to inhibit the air bag from being expanded rearwards of the vehicle body at an initial stage of deployment by the deployment-limiting sheet, thereby avoiding the early interference with an occupant.

The navigation system is mounted on the electric automobile. A destination, to which one wants to drive by the automobile, is inputted as drive plan information. Based on a distance planned to be driven by the automobile to the destination and a remaining capacity of the battery determined by remaining capacity detector, it is determined whether the automobile can reach the destination with the remaining capacity of the battery.

Abstract: This invention relates to a braking control system for an electric automobile that runs by driving wheels with an electric motor. The braking control system controls braking of a vehicle through regenerative braking by the motor. Upon application of brakes, the braking control system can make combined use of mechanical braking by a mechanical brake system (11) and regenerative braking by a drive motor (2). The braking control system is designed to control regenerative braking of the motor (2) by a regenerative braking control device (12) so that greater braking force is produced when a failure in the mechanical brake system (11) is detected by a failure detection device (22) than when the mechanical brake system (11) is detected to be normal.
