    • 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.
    • 本发明的目的是提供一种启动和停止燃气轮机和起动和停止控制装置的方法,其能够解决由于吹扫气体而导致的燃料气体的正常点燃故障的问题( 氮气)残留在燃料气体管中,从而稳定地点燃燃料气体。 为此,启动和停止控制装置在启动燃气轮机时,通过依次执行以下步骤来执行控制:第一废气管道吹扫,用于从压缩机推出压缩空气中的残留在废气管道中的燃料气体; 用于通过打开燃料气体截止阀,在燃料气体停止燃气轮机时,在燃料气体切断阀和燃烧器之间排出残留在燃料气体管道中的氮气的燃料气体管道吹扫; 以及第二废气管道吹扫,用于在通过来自压缩机的压缩空气吹扫燃料气体管道时推出残留在排气管道中的燃料气体,然后通过打开燃料气体将燃料气体供应到燃烧器 关闭阀再次点火。

    • A solid immersion lens holder 200 includes a holder main body 8 having a lens holding unit 60 that holds a solid immersion lens 6, and an objective lens socket 9 for attaching the holder main body 8 to a front end of an objective lens 21. The solid immersion lens 6 is held in a state of being unfixed to be free with respect to the lens holding unit 60. A vibration generator unit 120 that causes the holder main body 8 to vibrate is attached to the objective lens socket 9. The vibration generator unit 120 has a vibrating motor 140 held by a motor holding member 130, and a weight 142 structured to be eccentric by weight is attached to an output shaft 141 of the vibrating motor 140. A vibration generated in the vibration generator unit 120 is transmitted to the solid immersion lens 6 via the objective lens socket 9 and the holder main body 8. Thereby, achieving the solid immersion lens holder capable of improving the close contact between the solid immersion lens and an observation object.
