Abstract: An electrolyte composition and catalyst ink, a solid electrolyte membrane formed by printing the electrolyte composition and catalyst ink, and a secondary battery including the solid electrolyte membrane. An electrolyte composition includes a solvent; a lithium salt dissolved in the solvent; and a cycloolefin-based monomer dissolved or dispersed in the solvent and a catalyst ink includes a catalyst that promotes the ring-opening and polymerization reactions of the cycloolefin monomers of the electrolyte composition.

Abstract: A method of controlling scrolling of contents provided in an electronic device including a touch screen and a scroll controlling region including a scroll pointer. The method includes sensing a touch on at a location in the scroll controlling region on the touch screen; sensing movement of the touch on to a location out of a scroll moving region on the touch screen; and changing a scrolling rate based on the sensed location out of the scroll moving region to control scrolling of the provided contents.

Abstract: A combination system including a plurality of reproducing apparatuses, such as a digital versatile disk player (DVDP) and a video cassette recorder, and a method for controlling operation of the same. The combination unit includes a selecting unit for selecting a reproduced signal provided by one of the plurality of reproducing apparatuses that is switched to a play mode, a selection information storing unit for storing selection information identifying the reproducing apparatus that outputs the reproduced signal selected by the selecting unit, and a control unit for controlling the reproducing apparatus to switch to a pause mode or a stop mode when the selection information stored in the selection information storing unit changes from identifying the reproducing apparatus to identifying another reproducing apparatus of the plurality of reproducing apparatuses.

Abstract: There is disclosed a hinge mechanism for use in a portable phone having a phone body and a cover, the hinge mechanism configured to mechanically couple the cover to the phone body. The hinge mechanism includes at least one hinge module mounted to the phone body and configured to hinge the cover with respect to the phone body for opening and closing the cover. The hinge module includes a hinge housing having a bottom wall and a pair of opposite lateral end walls spaced from each other, one of the lateral walls having a hole. The hinge housing also has a pair of opposite longitudinal end walls spaced from each other. A hinge shaft is mounted in the housing and has a mountain-shaped portion provided with a pair of opposite cam surfaces at one longitudinal portion thereof and a shaft portion at the other longitudinal portion thereof.
