Abstract: PURPOSE: To provide a method for treating a fluorine-containing waste liquid wherein the treating capacity is kept high and the maintenance is easy by adding a calcium salt and an inorganic flocculant to the liquid and filtering it by a cross-flow method. CONSTITUTION: This treating method comprises introducing a fluorine-containing waste liquid into a flocculation vessel 1; supplying slaked lime and an inorganic flocculant respectively by using a slaked lime supply section 2 and an inorganic flocculant supply section 3; sufficiently agitating the liquid; introducing the liquid containing the resultant flocculate into a circulation vessel 4; and circulating the liquid through a pipe 11, a filtration section 5, a pipe 12, and the circulation vessel 4. In this circulation process, the liquid flows along a filtration membrane 5b and a part of the liquid permeates the filtration membrane 5b and flows out to the outside. Thus, a flocculate having a large particle size and easily separable from water can be selectively deposited on the filtration membrane 5b by applying a cross-flow method wherein the liquid to be treated containing a flocculate made coarse by the addition of an inorganic flocculant is filtered while the liquid is being caused to flow along the filtration membrane 5b.

Title: Exhaust gas recirculation valve for car
Inventor: JANG SEONG HWAN
IPC: F02M25/07
Filed: 2000-03-30
Abstract: PURPOSE: An EGR valve is provided to promote the fuel efficiency of a vehicle by surely discriminating a state needing exhaust gas recirculation or a state not needing exhaust gas recirculation through the improved attachment of an EGR valve to an exhaust manifold and the change of the shaft of a valve controlling exhaust gas recirculation amount. CONSTITUTION: An EGR valve(200) including a back pressure hose(100), an exhaust gas recirculation amount adjusting valve(130) and a spring(140) is mounted to vertically open and shut the flow of exhaust gas recirculating through an exhaust manifold(120). When a vehicle is operated in a range needing exhaust gas recirculation, an ECU(Electronic Control Unit) transmits a back pressure generating signal to an actuator. The actuator generates back pressure and feeds the back pressure to the back pressure hose of the EGR valve. By the back pressure, opening degree of the valve(130) is adjusted and exhaust gas recirculation amount is regulated. In a range not needing exhaust gas recirculation, back pressure is not generated and the valve(130) is closed by the tension of the spring. Thus, recirculation from the exhaust manifold from an intake manifold is restrained.

Inventor: KIM SANG HEON
IPC: C12N1/19
Filed: 2000-04-08
Abstract: PURPOSE: Provided is a method for detecting an inhibitor of human immunodeficiency virus(HIV) using an E.coli strain JM109(KFCC-1159) cotransformed with vector pJC1 for the expression of HIV nucleocapside protein, and vector pNH1Psi(SL1234) including nucleotide sequence SL 1234(SEQ ID: NO.1) of HIV ψ and beta-galactosidase reporter gene(SEQ IN: NO.2). Therefore, it can be effectively used for the development of anti HIV inhibitor. CONSTITUTION: The detection method of HIV inhibitor comprises the steps of: culturing E.coli JM109(KFCC-11159) cotransformed with vector pJC1 and vector pNH1Psi(SL1234); treating the culture with a compound supposed to be an inhibitor of HIV; and measuring the expression level of beta-galactosidase in culture broth, decreased by the compound. The transformant characteristically decreases the expression of beta-galactosidase by linking nucleotide sequences of HIV protein and HIV ψ, and is thus used for the detection of HIV inhibitor.
