Abstract: It is necessary to suppress the interruption of the power supply when the power source is changed. A power receiving apparatus receives power from a first power source or a second power source, and one of power from the first power source and power converted by a voltage conversion unit is supplied to a load unit, based on a result of detection of whether the power receiving apparatus is connected to the first power source, a result of detection of whether the power receiving apparatus is connected to the second power source, and a voltage that can be supplied from the second power source.

Abstract: An exhaust gas filter for purifying exhaust gases including particulate matter discharged from an internal combustion engine includes a honeycomb structure whose axial direction matches an exhaust gas flow, a plug portion which selectively plugs upstream end faces of the honeycomb structure which faces the exhaust gas flow, and catalyst carried on the honeycomb structure. The honeycomb structure has a plurality of partition walls and cells surrounded by the partition walls, and pores formed inside partition walls between adjacent cells communicating with each other. The plurality of the cells have open cells which are penetrated in the axial direction and plugged cells having one upstream end which face the exhaust gas flow plugged by the plug portion. The honeycomb structure has a first region which does not carry the catalyst on the partition walls and a second region which carries the catalyst on the partition walls.
