Disclosed is a motor and a drain pump including the same. The motor includes a rotor, a rotation shaft positioned through a center of the rotor, and a shaft fixing member for supporting the rotor and the rotation shaft, in which the shaft fixing member and the rotor include a fixing device provided in a direction that intersects a rotation direction of the rotation shaft to prevent the rotation shaft from being idle.

There is disclosed a cup comprising a cup body comprising an opening and provided to contain a beverage; and a handle part provided in an outer surface of the cup body and configured to be holdable by a user, wherein the handle part forms a preset angle with respect to an outer surface of the cup body so that the cup body supported by handle part is spaced from a table surface or floor when the handle part in contact with the table surface or floor, and wherein the length or width at which the handle part is formed is provided in a size such that when the handle part contacts with the table surface or floor, an imaginary normal extending from the table surface or floor to the center of gravity of the cup body to pass through the handle part.

A drainage pump includes a housing that defines a receiving space configured to receive fluid. The housing defines a suction port configured to introduce fluid into the receiving space, and a first discharge port and a second discharge port that are configured to discharge the fluid in the receiving space to an outside of the housing. The drainage pump further includes an impeller disposed in the receiving space and configured to rotate about a rotation axis to thereby discharge the fluid in the receiving space through the first discharge port or the second discharge port; a first rib that protrudes from an inner circumferential surface of the housing toward a center of the receiving space and that is disposed between the first discharge port and the second discharge port; and a second rib that protrudes from a portion of the first rib toward the center of the receiving space.

Drainage pump and cloth treating apparatus including same

A method for producing tetraalkoxysilane includes reacting a compound represented by Chemical Formula 1 below with an alkali metal at a molar ratio ranging from 1.0:1.0 to 1.0:1.1 and in the absence of a solvent to produce a basic catalyst represented by Chemical Formula 2 below; and mixing the basic catalyst represented by Chemical Formula 2, silicon metal, and an alcohol represented by Chemical Formula 3 below to produce tetraalkoxysilane: Chemical Formula 1O(CHRCHO)&#x2014;H, Chemical Formula 2O(CHRCHO)-, and Chemical Formula 3OH, where M is alkali metal, Rrepresents a C1-C5 linear hydrocarbon group or a C3-C5 branched hydrocarbon group, Rrepresents H or a C1-C3 linear hydrocarbon group, Rrepresents a C1-C2 alkyl group, and n is an integer of 2-3. Thus, it is possible to increase the proportion of the catalyst in the process, and to minimize production of impurities caused by solvent decomposition.

Method for continuous production of tetraalkoxysilane

Disclosed is an organic framework including: planar layers formed by successively connecting building blocks arranged in the vicinity of each other, in which each of the building blocks includes two or three Cto Caromatic ring groups covalently bonded to a linear or annular boron-containing cluster; and a Lewis base coordinated to the boron-containing cluster within the planar layers.

Organic framework

Disclosed does a porous crystal comprising ammonia borane in which the ammonia borane is chemically bonded thereto by a chemical reaction while a porous crystal structure is maintained.

The present invention, by coating the polymer electrolyte membranes for fuel cells with inorganic thin films via a PECVD method or a reactive sputtering method, reduces the methanol crossover sizably without seriously reducing the ionic conductivity of polymer electrolyte membranes, thereby, when applied to fuel cells, realizes a high performance of fuel cells. A surface of membrane can be coated with inorganic thin films made of inorganic materials, which are for example silicone oxide, titanium oxide, etc., so as to make composite polymer electrolyte membrane. For coating, plasma enhanced chemical vapor deposition method or reactive method can be used.
