Title: Method for suppressing generation of ring shaped attachment on inner wall of lime kiln
Inventor: SEO IN GUK
IPC: F27D25/00
Filed: 1998-12-29
Abstract: PURPOSE: A method is provided to suppress the growing and attachment of a ring shaped attachment on the inner wall of a lime kiln. CONSTITUTION: High temperature flame is prevented from touching the wall of a lime kiln by installing a flame diffusion preventing board(5). The flame diffusion preventing board has two shapes.

The RF unit receives a radio signal to convert the signal into an analog signal, and outputs the analog signal to the modem or converts a digital signal of the modem into an analog signal to convert the analog signal into a radio signal, then transmits the radio signal to a base station. The modem converts the analog signal of the RF unit into a digital signal to combine the digital signal, and outputs service information to the time switch or spreads the service information to output the information to the RF unit. The time switch outputs the service information to a U-interface or switches the service information in a time slot, then outputs the information to the modem. The time switch supplies a clock and a frame synchronous signal to the U-interface. The D-channel processor outputs integrated service digital network(ISDN) D-channel messages of the time switch and the U-interface to the controller, or outputs an ISDN D-channel message of the controller to the time switch and the U-interface. The controller performs controlling processes for operations of each block in the RIU. The S-interface performs activation/deactivation processes for pseudo-ternary coding and a layer1, and interfaces terminal adapters(TAs) with terminal equipments(TEs1) of the RIU and an ISDN by performing functions in an S reference point.

Title: Liquid crystal display
Inventor: SHIN JUNG HYEOK
IPC: G02F1/1335
Filed: 1999-06-23
Abstract: PURPOSE: A liquid crystal display is provided to prevent flicker generation by applying an exactly clocked pulse width modulation(PWM) frequency to a plurality of inverters. CONSTITUTION: A liquid crystal display comprises a plurality of inverters(150,153,155) which are electrically connected to corresponding lamps(130) via a wire and supply a power to the corresponding lamps(130). A PWM illuminating part(200) is connected to the inverters(150,153,155) via a wire and applies a PWM frequency to each of the inverters(150,153,155) so as to be synchronized with PWM frequencies of the inverters(150,153,155).

Abstract: PURPOSE: A method for manufacturing a capacitor of a semiconductor device is provided to increase electric permittivity and to reduce a leakage current, by forming a TaON dielectric layer by a surface chemical reaction using NH3 gas and evaporated gas of Ta(N(CH3)2)5. CONSTITUTION: A semiconductor substrate(11) having a lower structure for forming a capacitor of a semiconductor device is prepared. A storage electrode(13) is formed on the semiconductor substrate. A nitride layer is formed on the entire structure to prevent a native oxide layer from being grown on the storage electrode. A TaON dielectric layer is formed on the entire structure including the nitride layer by using Ta(N(CH3)2)5 as a precursor. Impurities in the TaON dielectric layer are removed. A plate electrode is formed.

Abstract: PURPOSE: A high-speed fillet welder is provided to reduce a welding time with high quality by welding a steel structure at high speed more than 2m/min. CONSTITUTION: A high-speed fillet welder comprises a motor(20), a rotary cam(30) and a slide block(50). The motor generates rotary power on the outer side of a slide torch(15), and the rotary cam is installed in the end of the rotary shaft of the motor. The slide block in the slide torch forms a through hole(55) passing a welding wire(5) through the center and vibrating the welding wire by the rotation of the rotary cam through a connecting pin(40). Thus, the fillet welder welds a bonding face of a steel structure without a welding trouble.
