Abstract:
A dual type cosmetics case includes a plurality of liquid containing parts and inlets partitioned from each other by a vertical partition wall. A plurality of stems immersed into the respective liquid containing parts are mounted in such a way as to be detachably coupled to the liquid containing parts. Each stem is selectively coupled to a cap and then used. The dual type cosmetics case is advantageous in that different kinds or colors of cosmetic liquids are held in one case, so that a user need not carry or keep several different cosmetics, and thus, especially while traveling, the volume of items which are to be carried by a person can be reduced. Further, costs for purchasing cosmetics can be reduced, so that the cosmetics case is very economical.
Abstract:
The present invention relates to a method of producing aromatic products (benzene/toluene/xylene) and olefin products from petroleum fractions obtained by fluid catalytic cracking, and, more particularly, to a method of producing products comprising high-concentration aromatic products and high value-added light olefin products from light cycle oil obtained by fluid catalytic cracking.
Abstract:
A deskew system includes a first voltage control delay receiving a data signal and generating N-numbered delayed data signals obtained by delaying a phase of the data signal in units of 90/N, where N is a natural number that is not less than 1. In response to a phase control signal, a second voltage control delay receives a clock and generates N-numbered delayed clocks by delaying a phase of the clock in units of 90/N. A skew compensation control unit generates a plurality of skew control signals to compensate for skew between the data signal and the clock based on the data signal, the N-numbered delayed data signals, the clock, and the N-numbered delayed clocks.

Abstract:
The present invention relates to a single container for multi-applicator with single or multi-housing chambers, the single container including: a body part in which one or more kinds of liquids are contained in a separated state from each other; a plurality of brush rod parts submergedly disposed in a plurality of housing chambers of the body part; and a cap part detachably coupled to the top end periphery of the body part so as to take out any selected one of the plurality of brush rod parts in the state of being coupled to the plurality of brush rod parts.
Abstract:
Disclosed herein is a method of regenerating a titanium-containing molecular sieve catalyst. Particularly, this invention provides a method of regenerating a titanium-containing molecular sieve catalyst used in epoxidation of olefin through simple treatment using a mixture solvent comprising aqueous hydrogen peroxide and alcohol. According to the method of this invention, when the catalyst having decreased activity is regenerated, the activity of the regenerated catalyst is equal to that of new catalyst and can be maintained stable for a long period of time.
Abstract:
The present invention relates to an arylphenoxy catalyst system producing an ethylene homopolymer or copolymers of ethylene and α-olefins, and a method of producing an ethylene homopolymer or copolymers of ethylene and α-olefins having a high molecular weight under a high temperature solution polymerization condition using the same. The catalyst system includes a group IV arylphenoxy-based transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst. In the transition metal catalyst, a cyclopentadiene derivative and arylphenoxide as fixed ligands are located around the group IV transition metal, arylphenoxide is substituted with at least one aryl derivative and is located at the ortho position thereof, and the ligands are not crosslinked to each other. The catalyst includes an environmentally-friendly raw material, synthesis of the catalyst is economical, and thermal stability of the catalyst is excellent. It is useful for producing an ethylene homopolymer or copolymers of ethylene and α-olefins having various physical properties in commercial polymerization processes.
