Abstract: According to an aspect of the present disclosure, there is provided a substrate treating apparatus comprising: a vessel part having a substrate treatment region formed therein and including a supply port through which a treating fluid is supplied to the substrate treatment region and an exhaust port through which the treating fluid is exhausted from the substrate treatment region; a fluid supply unit configured to supply the treating fluid to the substrate treatment region; an exhaust unit configured to exhaust the treating fluid from the vessel part. The exhaust unit comprises: a main line connected to the exhaust port; an extension line branched from at least one of first and second nodes of the main line and including at least one of a first orifice or a first check valve to control an exhaust speed; and an auxiliary line branched from a third node of the main line, where an orifice and a check valve are not formed.

Abstract: A substrate treating apparatus of the present disclosure comprises: a chamber member having an accommodation space configured to accommodate a vessel part where a substrate treatment region constituting a supercritical treatment space are formed, and an opening configured to move the substrate inside or outside; a shutter configured to open or close the chamber member; and a first exhaust part configured to discharge an internal air from the accommodation space to the outside, wherein the temperature of the substrate treatment region is increased.

Abstract: The present disclosure relates to a plurality of host materials, an organic electroluminescent compound, and an organic electroluminescent device comprising the same. By comprising a specific combination of host compounds and/or an organic electroluminescent compound according to the present disclosure as an organic electroluminescent material, an organic electroluminescent device having low driving voltage and/or high luminous efficiency and/or long lifespan characteristics can be provided.

Abstract: The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure, it is possible to produce an organic electroluminescent device having improved driving voltage, power efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

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.
