Abstract: A flexible printed circuit board is robust to a repeated twisting and consists of a minute circuit printed on a flexible insulated material sheet, and has the bent parts of the opposite edges symmetrical in structure. The bent parts are straightened out when twisting occurs. In the flexible printed circuit board, the opposite edges are longer in length than the middle part such that the tensile deformation at the opposite edges at the time of twisting does not occur or is minimized.

Abstract: A disk drive assembly including a disk drive, a bracket for containing the disk drive, and a damper for absorbing an impact transmitted to the disk drive. The damper may have a shape of a ring to encircle a corner of the disk drive and may be formed of an elastic material to buffer an impact transmitted between the disk drive and the bracket. Particularly, since the width and/or diameter of the damper may be formed with a minimized size, the damper is capable of providing sufficient buffering properties. In addition, the space occupied by the damper may further be minimized. Thus, since the space occupied by the disk drive assembly may be reduced, it is possible to favorably apply the assembly to a portable electronic device.

Abstract: A liquid crystal on silicon (LCOS) device includes a wafer, glass, and walls formed at opposite ends of an upper surface of the wafer to define a predetermined cell gap between the glass and the wafer. A thin piezo-electric layer is attached onto a surface of the wafer and an electrode is applied with external power to expand and/or contract the thin piezo-electric layer. The LCOS device further includes a voltage detection unit for detecting a voltage generated by the deformation of the thin piezo-electric layer; and a feedback control unit for compensating for deformation of the thin piezo-electric layer according to the voltage detected by the voltage detection unit. The LCOS device achieves uniformity of the cell gap by adjusting the voltage level of the thin piezo-electric layer after bonding the wafer and the glass, and therefore, spacers are not required.

Also, the bracket can not only effectively protect a disk drive from an external impact but also be applied to an electric device such as a portable device. Also, a bracket according to another embodiment can prevent mutual interference between circuits provided on the bracket.

Abstract: A dual type LCD module for a mobile phone includes: a main LCD; a sub LCD; and a bracket interposed between the main LCD and the sub LCD. The main LCD and sub LCD are separated by a first distance by the brackets, which covers a periphery of the main LCD and includes an opening in which the sub LCD is arranged. In accordance with the invention, the weight of the sub LCD is not applied to the main LCD when the phone is shocked, so that the main LCD is prevented from being deformed by the sub LCD.

Abstract: A terminal includes a lower housing; an upper housing slidably installed with respect to the lower housing; and a pressing member with both ends being supported by the lower and upper housings, respectively, for providing variable levels of pressure in diverse directions according to a sliding position of the upper housing with respect to the lower housing, wherein one end of the pressing member is movably linked to the lower housing. The small-sized pressing member provides a maximum level of pressure to facilitate the sliding movement of the upper housing with respect to the lower housing. Thus, space utilization can be improved.

Abstract: A method and apparatus for generating a three-dimensional FEM are provided. In the three-dimensional FEM generating method, a surface mesh is generated by meshing the surface of a three-dimensional model of a three-dimensional object. A projected contour is generated by projecting the three-dimensional model from one direction, and a projected contour mesh is generated by meshing the surface of the projected contour. A solid base mesh is generated by stacking solid elements on a base side formed of two-dimensional elements of the projected contour mesh. The surface mesh is substituted into the solid base mesh in alignment with the projected contour. A final solid mesh is generated by distinguishing solid elements surrounded by the surface mesh in the solid base mesh.
