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.

Abstract: A display driving integrated circuit (IC) and a display driving method for supporting various driving mode include an input unit, a digital-analog converter and a row data output unit. The row data output unit outputs at least one of the row data to a row line corresponding thereto for each row scan clock pulse. The row data output unit activates output paths for outputting the row data to the row lines in an activation order of a driving mode selected from a plurality of driving modes having different orders of activating the output paths in response to a mode select signal.

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.

Abstract: Provided is a picker for transferring packaged chips, including a picker base, a base block fixably connected to the picker base, a plurality of nozzle assemblies, provided to the base block, each nozzle assembly being movable up and down, and having a nozzle which a packaged chip is held against or released from by air pressure, an air pressure supplying unit supplying negative or positive pressure by which the packaged chip is held against or released from the nozzle, a plurality of first mechanisms, through each of which the negative or positive pressure is supplied to the nozzle; and a plurality of second mechanisms, each of which moves up and down each of nozzle assemblies.

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.

Abstract: A handler is provided, including a chamber in which to-be-tested packaged chips contained in a test tray are connected to sockets of a test board, an exchanging unit exchanging the test trays with the chamber; a transferring unit transferring the test tray containing the to-be-tested packaged chips from the exchanging unit to the chamber, and transferring the test tray containing tested packaged chips from the chamber to the exchanging unit, a picker removing the tested packaged chips from the test tray staying in the exchanging unit and putting the to-be-tested packaged chips into the test tray staying in the exchanging unit; and an inserting unit including a pusher pushing the test tray to connect the to-be-tested packaged chips to the sockets of the test board, a pusher driving unit driving the pusher, a sensor sensing an amount of pressure applied by the pusher to the test tray; and a controller controlling the pusher driving unit to enable the pusher to apply a proper amount of pressure to the test tray.
