  • Publication number: 20170294431
    Abstract: The present disclosure relates to a semiconductor chip having a level shifter with electro-static discharge (ESD) protection circuit and device applied to multiple power supply lines with high and low power input to protect the level shifter from the static ESD stress. More particularly, the present disclosure relates to a feature to protect a semiconductor device in a level shifter from the ESD stress by using ESD stress blocking region adjacent to a gate electrode of the semiconductor device. The ESD stress blocking region increases a gate resistance of the semiconductor device, which results in reducing the ESD stress applied to the semiconductor device.

  • Patent number: 9456972
    Abstract: Provided is niacin-peptide which has skin whitening activity. The peptide of the present invention has skin whitening activity by inhibiting melanogenesis, that is, by inhibiting the expression of a gene related to melanogenesis (for example, TRP-1, TRP2, or MIFT). The peptide of the present invention has high stability and skin permeability. Also provided is a cosmetic composition for skin whitening which contains the niacin-peptide.

  • Patent number: 8221674
    Abstract: A distributor bottom, particularly a nozzle-type distributor bottom, for steadily introducing process gas, especially process gas loaded with solid particles, into a process chamber, optionally to create a fluidized bed. The process chamber is disposed above the distributor bottom and is formed by walls of a reactor used for metallurgically, particularly thermally, treating feedstock. The distributor bottom is provided with a plurality of holes. Holes are arranged near the walls to prevent substances from attaching to the reactor walls. Special arrangements relate to nozzles and ducts.
