  • Publication number: 20140141292
    Abstract: The present invention relates to a storage-battery vent cap which adjusts an internal pressure of a storage battery by exhausting a gas generated inside the storage battery to the outside and blocking inflow of external air. The vent cap includes a cylindrical body installed in a vent hole of the battery and formed with an exhaust hole; a cylindrical insert coupled to the body, a partition being formed inside the insert and a coupling hole and a air vent being formed in the partition; and a valve fixed to the coupling hole and elastically deformed by an internal pressure of the battery to open the air vent. The valve has an umbrella-like shape including a valve body having a larger diameter than that of the coupling hole, a cover formed on an outer circumferential surface of the valve body, and a fixing portion downwardly protruded from the valve body.

  • Patent number: 8643632
    Abstract: A display device includes a display panel having an active area in which sub-pixels formed at crossing regions of data lines extending in a first direction and gate lines extending in a second direction crossing the first direction are arranged, and a non-active area outside of the active area. A driver supplies a drive signal to the gate and data lines in the display panel. Data links are extended in the first direction from the driver to supply a data signal to the data lines. Gate links are extended out from the driver and extended up to the active area in the first direction from the non-active area between the driver and the active area so as to supply a gate signal to the gate lines extending in the second direction. Accordingly, it is possible to reduce or minimize the area of the non-active area and/or to improve an aperture ratio.

  • Patent number: 8617857
    Abstract: The present invention relates to novel thraustochytrid-like microalgae having the ability to produce bio-oil, and a method of producing bio-oil using the same. The microalgae of the invention accumulate bio-oil at a high ratio in the cells when being cultured in glucose-containing medium, and thus can produce bio-oil in a high yield. Also, the microalgae can produce bio-oil using bean powder as a nitrogen source, and a product obtained by culturing edible bean powder as medium can be used as a raw material for producing food and feed. Also, the microalgae can produce bio-oil using non-food cellulosic biomass as a carbon source. Moreover, the use of non-food cellulosic biomass for production of bio-oil can overcome the factors limiting the development of bio-oil, including the unstable supply of food resources and an increase in the cost of raw materials, and can improve the commercial competitiveness of microbial fermentation oil.
