Abstract:
A folder-type portable apparatus including a body and a folder coupled to the body by a hinge device. An external display device having a first section and a second section, is disposed on the upper surface of the folder. A camera lens positioned adjacent to the external display device, and a sliding cover slides to reveal and cover the external device and the camera lens.
Abstract:
A folding-type portable apparatus having a display device and a camera lens, gradually and simultaneously exposed as the slider slides. The folding-type portable apparatus includes a body; a folder having a first display device positioned on the top surface thereof; and a slider provided with a camera lens housing having a camera lens and adapted to slide in the longitudinal direction of the folder while continuously facing the first display device to expose/hide the first display device and the camera lens, simultaneously and gradually as it slides.
Abstract:
A portable communication apparatus equipped with a tri-column type cradling function, and wide-view and stereophonic sound functions. The portable communication apparatus includes a central housing, a first housing rotatably coupled to the central housing about a first hinge axis in such a manner that the first housing is movable closely to or remotely from the central housing, a second housing rotatably coupled to the central housing about a second hinge axis, which is parallel to the first hinge axis, in such a manner that the second housing is movable closely to or remotely from the central housing and first housing, and a support unit for supporting the first and second housings, thereby maintaining the first and second housings and the central housing in a tri-column structure.
Abstract:
An electron amplifier and a method of manufacturing the same are provided. The electron amplifier includes a substrate in which a plurality of through holes are formed, a resistive layer deposited on the sidewalls of the through holes, an electron emissive layer including carbon nanotubes which is deposited on the resistive layer, and an electrode layer formed on each of the upper and lower sides of the substrate. Because the electron emissive layer of the electron amplifier is uniform and provides a high electron emission efficiency, the electron amplification efficiency is improved. The electron amplifier manufacturing method enables economical mass production of electron amplifiers.

Abstract:
A sliding-type portable communication apparatus includes a body housing; a sliding housing sliding on an upper surface of the body housing while being in contact with the body housing; first and second angled housings, each of the first angled housings extending from one corner of one side of the body housing in an inclined direction gradually going far from a lower surface of the sliding housing, each of the second angled housing having a first surface and a second surface, the first surface being in contact with the first angled housing while extending in the inclined direction, and the second surface being opposite to the first surface and in contact with the sliding housing; a pair of connecting arms, each of which extends from an end of one of the second angled housings in the inclined direction; and a rotatable lens housing disposed between the connecting arms and having a camera lens, the camera lens being oriented in a direction passing through the lower surface of the sliding housing when the sliding housing has not been moved a predetermined distance, and the camera lens being oriented in a direction passing through the upper surface of the body housing when the sliding housing has been moved.
Abstract:
Disclosed herein is a portable swing-type digital communication device with a step compensating mechanism. The portable swing-type digital communication device comprises a body housing, and a swing housing rotatably attached to the body housing by means of a hinge module. The swing housing is rotatable about a hinge axis at a prescribed angle perpendicular to the top surface of the body housing. The swing housing being disposed at a prescribed angle to a planar surface of the body housing when the swing housing is rotated a prescribed angle from the body housing. Also, the portable swing-type digital communication device comprises a step compensating mechanism for preventing a step between the top surface of the body housing and the top surface of the swing housing when the swing housing is rotated to the prescribed angle from the body housing.
