Abstract: A method of controlling compressor for refrigerator and apparatus thereof are disclosed to control an operation of the compressor by optimum efficiency by changing freezing capacity of the compressor. The apparatus controls a rotation direction of the compressor installed in the refrigerator and changes the freezing capacity of the compressor in accordance with the rotation direction of the compressor, thereby effectively controlling the operation of the compressor.

Abstract: A proton conducting titanate includes titanate and a sulfonic acid group-containing moiety having proton conductivity introduced into the surface of the titanate, in which the sulfonic acid group-containing moiety is directly bound to the titanate via an ether bond (—O). A polymer nano-composite membrane includes the proton conducting titanate, and a fuel cell includes the polymer nano-composite membrane. The proton conducting titanate is provided with a sulfonic acid functional group having proton conductivity, which increases the proton conductivity of the polymer nano-composite membrane. The polymer nano-composite membrane includes the proton conducting titanate, and thus can have a controllable degree of swelling in a methanol solution, and the transmittance of the polymer nano-composite membrane can be reduced. The polymer nano-composite membrane can be used as a proton conducting membrane in fuel cells to improve the thermal stability, energy density, and fuel efficiency of the fuel cells.

Abstract: A protective material comprising a flexible substrate including a top surface and a plurality of discrete guard plates affixed to the top surface in a spaced relationship to each other. The guard plates comprise a material which significantly expands upon the addition of sufficient heat forming a thermally insulating, flame retardant layer.

Abstract: A supple, globally flexible, composite protective material having guard plates on a substrate with a clearly visible pattern. The substrate is flexible and has a surface with a colored pattern including two or more colors. The guard plates are small, non-overlapping, printed resin material members having major and minor dimensions and are arranged in a predetermined pattern over a substantial portion of the surface of the substrate. In one embodiment of the invention the guard plates are transparent or translucent to visible light so that the colored pattern on the surface of the substrate is visible. In another embodiment the colors of the guard plates blend in with the colored pattern of the substrate.

Abstract: A proton conducting inorganic material having a layered structure in which a sulfonic acid group-containing moiety having proton conductivity is introduced in between the layers of an inorganic material having a nano-sized interlayer distance such that the sulfonic acid group-containing moiety is directly bound to the inorganic material via an ether bond. A polymer nano-composite membrane including the product of a reaction between the inorganic material having the sulfonic acid-containing moiety with a proton conducting polymer, and a fuel cell adopting the same, wherein the polymer nano-composite membrane has a structure in which a proton conducting polymer is intercalated between the layers of the proton conducting inorganic material having a layered structure, or a structure in which the product of exfoliating the proton conducting inorganic material having a layered structure is dispersed in a proton conducting polymer.

Abstract: A beverage container is disclosed. The beverage container includes a container body for containing carbonated beverage. A pumping lid assembly for selectively opening and closing the container body is inserted into the opening of the container body. The pumping lid assembly includes an extension cylinder engaged at its lower portion with the upper end portion of the container body. A pump housing is rotatably mounted in the interior of the upper portion of the extension cylinder. A plunger assembly is fitted into the central portion of the pump housing, and designed to pressurize air in the interior of the container body while being moved downward, to suck exterior air from the outside while being moved upward, and to rotate together with the pump housing and align the first and second beverage outlets so as to enable the discharge of carbonated beverage from the container body when being rotated.
