Abstract: A liquid crystal display including many speakers within a stand and having a display unit, a display angle of which can be adjusted by a cam in order that a user can conveniently see it. The stand supports the display unit through a support and has an inclined part between a front part and a rear part. In addition, a speaker for outputting a high-pitched sound is installed within the front part of the stand and speakers for outputting a middle-low pitched sound are installed within the both sides of the stand. The support is rotatably connected to the display unit and the stand by a driving of the cam and contacted with the cam provided to toe inclined part of the stand and the angle of the support is adjusted by a rotation of the cam and so an angle of the display unit is adjusted.

Abstract: A tower-shaped computer having a drive unit unifying an FDD (Floppy Disk Drive) and a CD-ROM drive (Compact Disk-Read Only Memory) horizontally on the lower part to improve the utility of the space effectively. There is provided a computer comprising a body having a receptacle in a lower part of a front face and a plurality of input-ports provided at a rear side of the receptacle; a drive unit being received in the receptacle such that a front portion thereof is protruded from the front face of the body, the drive unit includes a floppy disk drive integrated with a compact disk read-only memory drive and output ports positioned at a rear side thereof and connected to the input ports, respectively.

Abstract: A remote infrared password key system teaches entering a password with a remote control, conveniently entering a password by pressing one key utilizing a password hot key which also eliminates the need to store the password, and preventing unwanted disclosure of the password, by using a remote infrared password key system.

Abstract: A method for suppressing an electromagnetic wave in a semiconductor manufacturing process contemplates diffusion of a material into a region where active elements for processing a high speed digital signal are massed. During a wafer manufacturing process, high temperature particles of the material is diffused to shield the active elements of the integrated circuit from electromagnetic waves, and the integrated circuit is packaged in a circuit interlocking a wafer chip and external electrical conducting pins emanating from the integrated circuit are wrapped with a material exhibiting a resistance varying directly with the frequency of a high frequency components of electromagnetic interference. Since a main portion is surrounded by a material for shielding an electromagnetic wave in a wafer manufacturing process and a package manufacturing process for the manufactured wafer chip, electromagnetic shielding is obtained relative to other circuits on the chip.
