Abstract: An apparatus and a method of producing a vapor-grown carbon structure capable of obtaining a vapor-grown carbon structure with a markedly low production cost are provided. A vapor-grown carbon structure producing apparatus 1 has a screw feeder 4 for supplying a biomass raw material into a furnace 2, a thermal decomposition zone 5 having a first high-temperature air introducing nozzle 6 for thermally decomposing the supplied raw material at a thermal decomposition temperature of 500 to 900° C., a combustion zone 7 having a second high-temperature air introducing nozzle 8 for combusting a thermal decomposition product at a reaction temperature of 900 to 1300° C., and a charbed zone 9 for holding a combustion residue having passed through the combustion zone 7 and generating a carbon radical in a decomposition gas, to generate a vapor-grown carbon structure.

Abstract: A device is provided to be able to spray over a wide range and suppress a chilling injury. In the device, a rotating nozzle is connected to a connection pipe having a connection passage in communication to a nozzle stem of an aerosol can to have an outlet directed laterally. The rotating nozzle comprises a hollow support having a connection passage connected to a connection passage outlet of the connection pipe and a hollow arm rotatably supported at a tip end of the support, and an arm orifice is provided at a tip end of a connection passage in the arm and oriented such that reaction force of spray causes the rotating nozzle to rotate and aerosol contents are sprayed forwardly of a rotating plane of the rotating nozzle.
