  • Patent number: 8497333
    Abstract: Disclosed is a polylactic acid composition with improved heat-resistance and improved impact-resistance. Specifically, in the disclosed polylactic acid composition, both impact strength and heat-resistance are improved by mixing 30 to 80 wt % of polyketone and 10 to 40 wt % of modified rubber. The disclosed polylactic acid composition does not only exhibit excellent in heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance, etc., but also has improved impact-resistance and improved heat resistance. Thus, it is possible to employ polylactic acid as a bioplastic in interior/exterior parts of a vehicle.

  • Publication number: 20100104646
    Abstract: A nanoparticle composition is provided for preventing hair loss and promoting hair growth. It is based on herbal materials and thus has no harmful side effects on the body. When applied to the scalp, the nanoparticle composition deeply infiltrates into the dermis to promote blood circulation therein and provide nutrients thereto. Accordingly, the nanoparticle composition stimulates and activates hair follicles to thus promote the metabolism of hairs. Also, the nanoparticle composition exerts antioxidant activity on the scalp to thus inhibit depilation and aid in hair regrowth.

  • Publication number: 20080074120
    Abstract: Provided is a pushing block for use in a handle and a handler equipped with the pushing block. The pushing block includes pushing pins, provided under the test tray, each pushing the latch upwards from under the test tray to enable the latch to release the packaged chip, a first plate on which the pushing pins are provided, and an assembly changing horizontal motion into vertical motion to move the first plate vertically. Positioning of the pushing block under the test tray prevents interference between the pushing block and the picker during loading and unloading and makes it convenient to take corrective action when malfunction of the picker occurs.
