Abstract: In a power source system, a high-voltage battery and a low voltage battery are configured to store electric powers to be supplied to a traveling motor and an accessory, respectively. A step-up unit is interposed between the low-voltage battery and the traveling motor, and is configured to step up a voltage of the low-voltage battery and apply the stepped-up voltage to the traveling motor. A controller is configured to perform switching to a normal-time electric power supply circuit, in which the high-voltage battery and the traveling motor are coupled to each other, when the high-voltage battery is in a normal state and perform switching to an abnormal-time electric power supply circuit, in which the low-voltage battery and the traveling motor are coupled to each other via the step-up unit, when the high-voltage battery is in an abnormal state.

Abstract: A charging socket includes a fixed part, a charging opening, and a break member. A fixed part is configured to be fixed to an electric vehicle. A charging opening is to be inserted to a power feeding connector for charging a battery of the electric vehicle. A break member is configured to break and separate the charging opening from the fixed part when a predetermined amount or more of load is applied to the charging opening.

Abstract: An aircraft gas turbine is constituted by accommodating a compressor (14), a combustor (15), and a turbine (16) in a cylindrical main unit casing (12). A thick wall part (52) is provided on an outer periphery side of rotor blades (34) in the main unit casing. A cooling passage (53), for cooling the thick wall part (52) by circulating compressed air compressed by the compressor, is provided in the thick wall part. Also provided is a discharge passage (55) for discharging compressed air having circulated in the cooling passage to a combustion gas passage A. The structural strength of the thick wall part is ensured by appropriately cooling the thick wall part of the casing, while simplifying the structure and preventing a decrease in efficiency, thereby ensuring effective containment performance and an appropriate clearance between the casing and the rotor blades.
