Title: Preparation for ferric oxide
Inventor: KIM SANG-DON
IPC: C01B17/06
Filed: 1985-05-11
Granted: 1988-03-12
Abstract: The fluidization reactor for the invention consists of an external reactor tower and an internal reactor tower.  The oxidation of the iron sulfide by air introduction in the external reactor generates SO2 gas with heat, which moves over in flow to the internal reactor to make endothermic reaction with the iron sulfide in the reactor, thus removing the necessity of supplying heat for the reactions.  The SO2 gas from the external reactor is supplied in the amount of slightly more than the requirement for the reaction of SO2 an iron sulfide in internal reactor.  The iron sulfide is fed in the particle sizes of about 0.05-0.15mm.

Title: Color video signal reproducing apparatus
Inventor: EZAKI TADASHI
IPC: H04N9/79
Filed: 1988-06-23
Granted: 1998-11-16
Abstract: A video signal reproducing apparatus has a filter circuit (31) interposed in a transmission path for a reproduced luminance signal, and the characteristic of the filter circuit (31) desirably includes a band-eliminating characteristic and a comb-filter passband characteristic which can be selectively emphasized. When the reproduced luminance signal has a normal or relatively smaller frequency bandwidth or a relatively small line correlation component, or when the level of the reproduced carrier chrominance signal is high, the band-eliminating characteristic of the filter circuit is emphasized. The foregoing video signal reproducing apparatus is particularly suited for reproducing a color video signal that includes a wide band luminance signal, in which case the comb-filter passband characteristic of the filter circuit is selected or emphasized so as to reduce noise near the color subcarrier frequency, to avoid displacement of a reproduced picture of high definition in the vertical direction and also to avoid interference caused by the vertical non-correlation component of a color picture.

Patent KR-950003147-B1 (KR)
Title: Method for producing polyeter-ester polymer
Inventor: KIM KWANG-TAE
IPC: C08G63/91
Filed: 1991-06-29
Granted: 1995-04-01
Abstract: The polyether ester elastomer comprising the short chain ester unit of formula (I) and the long chain ether unit of formula (II) is prepared by adding the phenol based alkali metal salt of formula (III) and one or mixt. of primary or secondary amine when the output amt. of methanol is 70%, then ester exchanging reaction and polymerization. In the formulas R is divalant radical which is prepd. by removing carboxyl gp. from dicarboxylic acid having below 400 of Mw; D is divalant radical which is prepd. by removing hydroxy gp. from short chain diol having below 250 of Mw; G is divalent radical which is prepd. by removing hydroxy gp. from long chain ether glycal having 400-4000 of Mw. In the formula (III), R is benzene, antracence or phenantrane; R' is alkyl, aryl or halogen.; M is alkali metal.; m,n = 0.5.
