    摘要: This process for the desulfurization and denitration of light oil is effected by extraction with an organic solvent containing nitrogen. The invention also relates to light oil desulfurized and denitrated by said process as well as an organic solvent containing nitrogen for the extraction. The solvent is selected from among, for example, hetrocyclic compounds containing nitrogen, such as pyrrolidones, imidazolidinones, pyrimidinones and pyridinium salts, and acid amides. The combination of the process of this invention with any ordinary process for hydrodesulfurization enables the production of light oil having a sulfur content not exceeding 0.01% by weight. Light oil still containing benzothiophenone and dibenzothiophenone derivatives after hydrodesulfurization can be easily desulfurized to yield a desulfurized product not having any undesirable color, or any offensive smell. Also, the extraction of nitrogen compounds and aromatic compound from light oil is effected by the same process. As the re-extraction of sulfur compounds from the extracted phase or the separation of the extracted phase into the solvent and the extracted oil can be easily carried out, the solvent is reusable. The light oil treated according to the process of this invention enables a reduction of particulates in the combustion product thereof, and has a high cetane index.

    摘要: An optical head comprising a diffracting element having two tracking diffracting regions separated by a division line extending in a direction corresponding to a track direction of a recording medium, and one focusing diffracting region separated from the tracking diffracting regions by a division line extending in a direction corresponding to a radial direction of the recording medium. The optical head further comprises a light receiving element having two tracking light receiving regions for receiving diffracted lights produced in the tracking diffracting regions, and two adjoining focusing light receiving regions for receiving a diffracted light produced in the focusing diffracting region. The diffracted light produced in the focusing diffracting region always has a substantially constant light intensity, even when a tracking error occurs. As a result, an offset can be prevented from occurring in a focus error signal by finely adjusting the diffracting element.
