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.

Abstract: A vehicle control system monitors an infant possibly left behind in a cabin of a vehicle. The vehicle control system performs a danger avoidance process of either avoiding or reducing a danger to the infant based on a monitoring result. The vehicle control system includes an image acquirer for acquiring one or more vehicle stationary images indicating an interior of the cabin. The one or more vehicle stationary images are captured by an imaging device during stopping of the vehicle. A leaving behind determiner is provided to determine presence or absence of an infant left behind in the cabin based one or more vehicle stationary images.
