The dynamometer comprises the battery(3), the drive motor(5), the motor controller, the solar panel(17), the solar battery controller, the engine(11) and one or more alternators. The battery is mounted to the car body(9). The battery stores the electrical energy. The drive motor is connected to the driving shaft(14) of the rear wheel(10). The drive motor converts the electrical energy supplied from battery into the kinetic energy. The motor controller controls the operation of the drive motor. The solar panel is mounted on the exterior of the shingle(15). The solar panel obtains the electrical energy from sunlight. The solar battery controller is mounted between the solar panel and battery. The alternator produces current by the rotation driving power of the engine.

PURPOSE: An apparatus for restraining the melted substance of a reactor core from being generated in a nuclear power station is provided to safely cool the melted substance of a reactor core having a high temperature through the indirect cooling which is created by a plurality of coolant containing vessel disposed at the lower portion of the nuclear reactor. CONSTITUTION: The apparatus for restraining the melted substance of a reactor core from being generated in a nuclear power station comprises a wall of defense(30) installed at an inner middle portion of a pressure containment building(1) in the nuclear reactor; and a plurality of coolant containing vessels(20) positioned at a lower portion of a pressure vessel(2) disposed in the pressure containment building(1). The coolant containing vessels(20) are installed at a plurality of stages between the wall of defense(30) and a joint wall(1') of the pressure containment building(1). The upper surface of the coolant containing vessels(20) is inclined downwards from the joint wall(1') to wall of defense(30). A coolant containing vessel(50) is formed at a position opposite to the coolant containing vessels(20).

PURPOSE: A control method and an apparatus for battery charging and discharging for an on-line electric vehicle are provided to prevent battery life from being reduced due to frequent battery charging and discharging using power collected by a current collector for driving the electric vehicle and charging a battery. CONSTITUTION: A control unit(510) controls charging and discharging of a battery in an on-line electric vehicle. An input side charging switch(530) supplies charging power to the battery or stops supplying the charging power. An output side discharging switch(540) supplies or stops discharging power from/to the battery. A current collector driving control unit(550) controls the drive of a current collector. A collection power control unit(560) controls the collection power of the current collector in order to be used for driving the one-line electric vehicle.
