Patent number: 10130978Abstract: 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.Type: GrantFiled: October 16, 2015Date of Patent: November 20, 2018Assignees: SOFTARD INDUSTRIES CO., LTD., JXTG NIPPON OIL & ENERGY CORPORATIONInventors: Katsuhiko Kawakami, Guiqing Xu, Masayuki Kidokoro, Yasuo Uchida, Masanao Kato, Masanao Mitsuhata, Shouzou Sugihara, Tsukasa Mitsuta, Takayuki Nakazawa

Patent number: 9829736Abstract: 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.Type: GrantFiled: January 29, 2014Date of Patent: November 28, 2017Assignee: Sakai Display Products CorporationInventors: Takahiro Yoshikawa, Takayuki Nakazawa, Kazuhiko Negoro, Mayumi Hori
