Patent KR-920008416-B1 (KR)
Title: Magnetic recording medium with vertically oriented magnetic particles
Inventor: TAKAHASHI YASUNORI
IPC: G11B5/70
Filed: 1984-12-06
Granted: 1992-09-28
Abstract: A film type multilayer magnetic recording medium comprised of a film applied to a substratum in which coating film needle-shaped magnetic grains are orientated with their longitudinal axes perpendicular to the film surface in a multilayer state and having a film thickness of 1.1 to 2.0 times the average length of the grains, has an excellent property, because the angular ratio (Br Bs) of both horizontal and vertical components respectively are 0.6 or more. As a result, it is possible to attain a high density recording. The film type multilayer magnetic recording medium of the present inventions is manufactured by applying a fluid film forming material, in which neddle-shaped magnetic grains are dispersed to form a coating film having the thickness of 1.1 to 2.0 times the average length of the magnetic grains on a substratum, and then drying or hardening the film forming material in a magnetic field orientated perpendicularly toward the film surface.

Title: Method for preparation of polyester monofilament for zipper
Inventor: SHIN SANG-IL
IPC: D01F6/62
Filed: 1991-09-10
Granted: 1993-10-11
Abstract: The method for preparing the filament  having  good  slipping property comprises: adding dispersing agents, which are  shown  in formula (I) (where m  =  1-4,  n  =  1-3,  R1:lower  alkyl  group, A:titanium, zirconium, aluminium, X:alkylate, sulfonyl,  phenolic, carboxyl phosphate, etc., R2: lower ethylene  such  as  methylene, ethylene, isopropylene, oxoethylene,  Y:  acrylate,  methacrylate, amine) to the ethylene glycol with the adding rate of  10-50  wt.% against silicone microparticle to make an ethylene glycol  slurry, and  dispersing;  mixing  the  dispersed  slurry   with   silicone microparticles, on the surface of which silanol group  is  blocked by 0-70 wt.%, with the mixing rate of the silicones of 0.1-10 wt.% against polyester polymer to form a slurry; spinning and drawing.

Title: Process for producing porous ceramics
Inventor: KIM SU-TAE
IPC: C04B28/24
Filed: 1991-10-15
Granted: 1994-06-10
Abstract: The porous lightweight ceramics is produced by (a) heating and firing limestone, and removing carbon dioxide to make slaked lime, (b) mixing the slaked lime with ammonium dicarbonate (NH4HCO3) in the amount of 0.8-1.8 times the lime at -10 - 20 deg.C, (c) molding the mixt. at the high pressure, and (d) reacting it at 150 deg.C or less in the closed container. The lightweight ceramics has a good strength and heat-insulating property, and is used as interior or exterior materials for buildings.

Title: Method of searching tv channel automatically
Inventor: YU YON-SU
IPC: H04N5/50
Filed: 1991-11-20
Granted: 1995-03-08
Abstract: The method is designed to minimize TV channel searching time employing the wanted searching band of the user. The method comprises; a search mode selection step which search mode is selected from overall band, VHF low band, VHF high band, and UHF; a selection step of deciding whether all channel of the specified band is searched or not; a channel scope selection step from the selected band; a channel selection step from the channel scope.
