    摘要: The gas oil fraction hydrotreatment process of the invention is characterized by using a gas oil fraction with a sulfur content of 0.8-2% by mass and a total aromatic content of 20-35% by volume as the feed oil and subjecting the feed oil to hydrotreatment in the presence of a hydrogenation catalyst comprising at least one metal from among Group 6A metals and at least one metal from among Group 8 metals as active metals, and under reaction conditions with a reaction temperature of 330-390° C., a hydrogen partial pressure of 12-20 MPa and a liquid hourly space velocity of 0.1-1 h−1, to obtain an ultralow sulfur and low- aromatic gas oil fraction having a sulfur content of not greater than 1 ppm by mass and a total aromatic content of not greater than 1% by volume. This hydrotreatment process allows production of a “zero sulfur” and “zero aromatic” gas oil fraction in an efficient and reliable manner without provision of special operating conditions or equipment investment.

    摘要: A ultra-high density memory device utilizing a photoinductive ferromagnetic thin film. A photoinductive ferromagnetic thin film is formed on a GaAs substrate, and a tip is arranged so as to face the photoinductive ferromagnetic thin film. The GaAs substrate is disposed on an xyz scanner, and the three-dimensional positional relationship between the GaAs substrate and the tip is changed by the xyz scanner. Blue light is radiated onto the thin film in order to make the magnetization orientation of molecules uniform. Through application of a relatively high voltage, a relatively large current is caused to flow between the tip and the substrate, so that randomization of the magnetization orientation of molecules of the photoinductive ferromagnetic thin film; i.e., writing operation is carried out. Also, through uniform radiation of circular polarized light onto the GaAs substrate and application of a relatively low voltage, tunneling current is caused to flow between the tip and the substrate, which tunneling current changes in accordance with the magnetization orientation of molecules of the photoinductive ferromagnetic thin film. Through detection of the tunneling current, the magnetization orientation of molecules of the photoinductive ferromagnetic thin film can be detected.

    摘要: There is provided a method for upgrading hydrocarbon compounds, in which hydrocarbon compounds synthesized in a Fisher-Tropsch synthesis reaction are fractionally distillated, and the fractionally distillated hydrocarbon compounds are hydrotreated to produce liquid fuel products. The method includes fractionally distilling heavy hydrocarbon compounds synthesized in the Fisher-Tropsch synthesis reaction as a liquid into a first middle distillate and a wax fraction, and fractionally distilling light hydrocarbon compounds synthesized in the Fisher-Tropsch synthesis reaction as a gas into a second middle distillate and a light gas fraction.
