摘要:
An object of the present invention is to provide a method of starting and stopping a gas turbine and a start-and-stop control device, which are capable of solving a problem of a failure in normally igniting a fuel gas due to a purge gas (nitrogen gas) remaining in a fuel gas pipe and thereby igniting the fuel gas stably. For this purpose, the start-and-stop control device performs control at the time of starting the gas turbine by sequentially performing: first exhaust gas duct purge for pushing out a fuel gas remaining in an exhaust gas duct with compressed air from a compressor; fuel gas pipe purge for pushing out nitrogen gas remaining in a fuel gas pipe between a fuel gas shutoff valve and a combustor at the time of stopping the gas turbine by the fuel gas by opening a fuel gas shutoff valve; and second exhaust gas duct purge for pushing out the fuel gas remaining in the exhaust gas duct at the time of the fuel gas pipe purge by the compressed air from the compressor, and then the fuel gas is supplied to the combustor by opening the fuel gas shutoff valve again and ignited.

Provided are a substrate on which carbon nanotubes each having one end connected to the substrate can be formed at a high synthetic rate and from which the carbon nanotubes are less likely to be peeled off. The substrate is a substrate for forming the carbon nanotubes and includes a buffer layer 13 formed on at least one of surfaces of a substrate main body 14 and containing aluminum atoms and fluorine atoms. The carbon nanotube complex includes the substrate and a plurality of carbon nanotubes 11 each having one end connected to a surface of the buffer layer 13.

The present invention provides an energy device including a carbon nanotube electrode which prevents a carbon nanotube from peeling from an electric conductor. The energy device includes rolled electrode bodies, wherein at least one of the electrode bodies is formed such that a carbon nanotube layer is formed on the electric conductor, and concave regions are formed in a stripe shape on the carbon nanotube layer so as to extend in a direction parallel to a roll axis.

A toner is provided which is excellent in development stability in both a low-temperature, low-humidity environment and a high-temperature, high-humidity environment over a long time period. The toner includes toner particles containing at least a binder resin and a colorant, and a fatty acid metal salt. The fatty acid metal salt has a volume-based median diameter (D50s) of 0.15 μm or more and 0.65 μm or less, and the liberation ratio of the fatty acid metal salt in the toner is 1.0% or more and 25.0% or less.
