Abstract: Liquid hydrogen is produced while reducing emission of carbon dioxide to the atmosphere. Provided is a liquid hydrogen production device including: a carbon dioxide cycle plant (2), which includes a turbine (23) using a carbon dioxide fluid as a driving fluid, and is configured to drive the turbine (23) to generate motive power with use of a carbon dioxide cycle in which the carbon dioxide fluid discharged from the turbine (23) is increased in pressure and heated and is then re-supplied to the turbine (23); and a liquefaction plant (4) configured to cool gaseous hydrogen by heat exchange with a refrigerant, to obtain liquid hydrogen. The motive power generated by driving of the turbine (23) is used as motive power to be consumed in the liquefaction plant (4).

Abstract: A natural gas liquefying apparatus includes: a precooling unit, which is a treatment unit configured to precool natural gas; a liquefying unit, which is a treatment unit configured to liquefy the natural gas; a refrigerant cooling unit, which is a treatment unit configured to cool a liquefying refrigerant; a compression unit configured to compress vaporized refrigerants; and a pipe rack including air-cooled coolers arrayed and arranged on an upper surface. The treatment units and the compression unit are separately arranged in a first arrangement region and a second arrangement region arranged opposed to each other across a long side of the pipe rack. The pipe rack interposed between the first and second arrangement regions has a region in which no air-cooled cooler is arranged in order to arrange a plurality of pipes, through which refrigerants are allowed to flow, in a direction of a short side of the pipe rack.

Abstract: In a method for manufacturing a MOS transistor, a MOS transistor isolation layer is formed within a semiconductor substrate to surround an area for forming the MOS transistor in the semiconductor substrate. Then, first impurities are introduced into the area of the semiconductor substrate to adjust a threshold voltage of the MOS transistor. Also, second impurities are introduced into only a part of a periphery of the above-mentioned area adjacent to the MOS transistor isolation layer above which a gate electrode of the MOS transistor will be formed.
