Abstract: Compact cosmetic case with airtight sealed structure, which has a simple construction and enhances its airtight sealed effect to prevent a leakage of cosmetics, such as powder, thus improving quality, increasing productivity and reducing the production costs. The compact cosmetic case includes a body, an inner casing to contain the powder, an inner lid hinged the inner casing and having a powder puff seat, and an outer lid hinged to the body and having a locking part. A groove is formed around an upper surface of the inner casing, with liquid rubber filling the groove to form a rubber seal. A locking hole is formed on the inner casing, while a locking lever having a locking projection is formed on the inner lid to be locked to the locking hole.

Abstract: A method and system for improving a channel change rate using a conditional access table/program map table (CAT/PMT) to be transmitted in an out-of-band (OOB) band. First main data including a channel ID of a scrambled channel and Conditional access table (CAT) information corresponding thereto and defining a version is transmitted from a main program of a conditional access system (CAS) headend. Second main data including the channel ID and Program map table (PMT) information corresponding thereto and defining a version is transmitted from a main program of a demux/remux device. Third main data generated by receiving and combining the first and second main data is included in service information (SI) and is transmitted in an Out-of-band (OOB) band. After extracting only the third main data from the transmitted Service information (SI) in response to a channel change event signal, encrypted broadcast content of each channel is released and provided to a user.

The vertical organic thin film transistor is advantageous because it exhibits excellent current-voltage properties due to a short channel length, and has simple fabrication processes. Also, in the vertical organic thin film transistor, current properties in response to the gate voltage are of an enhancement type. Therefore, the vertical organic thin film transistor may be fabricated into the organic light-emitting transistor through a simple process.
