Title: Method for amplifying carbon powder at high speed to maintain carbon powder density in re-blowing work
Inventor: PARK JONG HYEON
IPC: C21B5/00
Filed: 1998-12-21
Abstract: PURPOSE: A method for amplifying carbon power at high speed is provided to regulate density of carbon powder blown into a melting furnace by changing carbon powder amount according to wind flow in order to improve ventilation of a burning stand and a softening thermal bonding layer. CONSTITUTION: A system decides if a blowing apparatus for carbon powder is normal in a re-blowing work. If so, the system decides wind flow is well suit for blowing carbon powder. Then, the system sets carbon powder amount for a normal work. A mode is selected for mutually communicating the system and a carbon powder density controlling operator. The system decides if the operator's output is way out of 0.2 T/H range from the up and the down. If so, the system decides that wind flow is increased and changes blowing amount of carbon powder.

Title: Hot and cold water dispenser of generating supersonic waves for eliminating harmful insects
Inventor: E KESH HE
IPC: F25D11/00
Filed: 1998-12-28
Abstract: PURPOSE: A hot and cold water dispenser with a supersonic waves generator is provided to eliminate harmful insects easily grown near or inside of the dispenser caused by fallen water. CONSTITUTION: A supersonic waves generating unit receives electricity from an electric power unit supplying alternating current of 100V/200V. Then, a rectifying unit(20) formed by a transformer(T) and a bridge rectifying circuit(BD) rectifies the alternating current into continuous current. Herein, a frequency converting unit(40) is installed for varying the band of frequency to prevent harmful insects from being adapted to supersonic waves. The rectified electricity is inputted to the frequency converting unit for being switched into each terminal(a,b,c) of a switch. Thus, if the electricity is connected to the terminal a, a low frequency is generated by serially connecting coils(L1,L3) of a frequency generating unit(30) with a condenser(C3). If the electricity is connected to the terminal b, a relatively low frequency is generated by serially connecting the coil(L3) of the frequency generating unit with the condenser. Therefore, the frequency generating unit is formed by the coils, the condensers(C1,C2), a resistance(R1), and a field effect transistor(FET) for generating supersonic waves frequency.
