摘要: A method of Auger Electron Spectroscopic (AES) analysis for a surface of an insulating sample. The method is characterized by performing an AES analysis after depositing a conductive layer of a designated thickness on the surface of a sample containing an insulating layer by means of an ion beam sputtering for the purpose of the preventing charge accumulation. The conductive layer preferably is deposited to have a thickness of at least 6 .ANG. to 50 .ANG. and a beam voltage used for applying the conductive layer is at least 3 Kev. The conductive layer is made of any of iridium(Ir), chrome(Cr) and gold(Au). Because any electron charge generated on the sample is discharged via the conductive layer, the AES analysis can be performed for a sample containing an insulating layer.

摘要: A natural gas-using hydrogen generator is provided which is able to produce high purity hydrogen from natural gas and water. The generator comprises a desulfurization reactor, a reformer and a PSA. The natural gas-using hydrogen generator also comprises a first pipe line for connecting the reformer with the desulfurization reactor to provide hot combustion gas from the reformer to the desulfurization reactor. A first valve controls air flow being fed to the reformer, which is provided on a second pipe line for feeding air into the reformer. A heat exchanger is provided for exchanging heat between a third pipe line, whose both ends are connected to the second pipe line with the first valve therebetween. A fourth pipe line leads a hot product gas from the reformer to the CO conversion reactor to cool the product gas. A second valve, provided on the third pipe line, controls air flow being fed to the third pipe line.
