  • Patent number: 10130978
    Abstract: Crude oil is discharged from an oil tank. A nozzle is inserted into a support opening formed in advance on a roof of the oil tank. A cleaning liquid containing LCO is injected from the nozzle over the sludge accumulated inside the oil tank after the crude oil is discharged from the oil tank. The cleaning liquid in which the sludge is dissolved is discharged from the oil tank and is returned to the oil tank for recycle cleaning. Subsequently, the cleaning liquid in which the sludge is dissolved is discharged from the oil tank.

  • Patent number: 9829736
    Abstract: Provided is a display device comprising a liquid-crystal panel and an optical sheet member including multiple stacked optical sheets emitting light from a light source toward the liquid-crystal panel, which can alleviate unevenness in light even in the case where, for example, light with such unevenness is emitted from the optical sheet member due to warps or wrinkles generated in the optical sheet member caused by heat generated by the light source. A diffusion sheet is provided between a liquid-crystal panel and an optical sheet member with a gap from the optical sheet member. The light emitted through the optical sheet member is diffused by the diffusion sheet and gap, and then enters the liquid-crystal panel.

  • Patent number: 7908245
    Abstract: Database management involving obtaining a request of update of a record of a database including: (i) pages with records, each including data and transaction identification information (XID) that has a range that is divided by a predetermined range; and (ii) generation identification information (GID) that is increased when the XID's value exceeds the divided range, where the page includes a GID header indicating the earliest GID of the records of the page. Also, reading a page's GID header when switching pages, comparing the GID header with the present GID of the present XID, and performing a freeze process to the record having the XID included in the page's GID header when the GID header's value is less than the difference between the GID's value to which the present XID belongs and a predetermined value.
