Abstract: In an automobile equipped with a drive motor, a positive value is set to a distribution factor during EV driving in a first CD mode. During EV driving in a second CD mode (a mode in which driving performance is limited as compared to the first CD mode), a value 0 is set to the distribution factor. First and second boosting converters are controlled such that an electric current (discharge power from the second battery) of a reactor of a second boosting converter when the distribution factor is small becomes smaller as compared to that when the distribution factor is large.

Abstract: An exhaust gas recirculation device capable of restraining generation of condensate water in an EGR path after engine stoppage is provided. When ignition is switched from ON to OFF, fuel injection is prohibited. As a result, a gas (fresh air) that flows into a cylinder after the switching is discharged into an exhaust passage without burning. In the present invention, a valve opening timing of an exhaust valve is changed so that a high peak portion of a pulsation of the gas arises at an EGR branch point, and the EGR valve is opened. Thereby, the fresh air flowing in the exhaust passage can be introduced into an EGR passage, and therefore an EGR gas in the EGR passage can be replaced with the fresh air.

The parallel on-off valve maintains communication between a left side first fluid room of the left cylinder and a right side first fluid room of the right cylinder and maintains communication between a left side second fluid room of the left cylinder and a right side second fluid room of the right cylinder by opening itself. The parallel on-off valve cuts off the communication by closing itself. The valve controller switches an opening/closing state of the parallel on-off valve based on a running state of a vehicle or an operation state of the vehicle by a driver.

Abstract: A second power storage device is electrically connected to a positive electrode line and a negative electrode line, and electric power for generating a driving force is directly supplied to an inverter section. A converter section supplies electric power received from the inverter section to a first power storage device. Because a backflow prevention circuit is provided, the electric power is not supplied in the direction of the second power storage device at this point. A diode of the backflow prevention circuit is connected between a system main relay and the connection node of a positive electrode line on the positive electrode line branching off from the positive electrode line and connected to the second power storage device. The diode controls the flow of a current from the positive electrode line side toward the second power storage device.

Abstract: It is an object of the present invention to provide a film-forming apparatus and a film-forming method that can prolong the lifetime of heaters used under high temperature conditions in an epitaxial growth technique. An inert gas discharge portion supplies an inert gas into the space containing the heater, gas is then discharged through the gas discharge portion without influence on the semiconductor substrate during film formation. It is therefore possible to prevent the reaction gas entering into the space containing the high-temperature heaters. This makes it possible to prevent a reaction between hydrogen gas contained in the reaction gas and SiC constituting the heaters. Therefore, it is possible to prevent carbon used as a base material of the heaters from being exposed due to the decomposition of SiC and then reacting with hydrogen gas. This makes it possible to prolong the lifetime of the heaters.
