Title: Two stage swirl-flow fluidized bed coal combustors and method
Inventor: CHON HAE-SU
Filed: 1991-03-09
Granted: 1994-05-17
Abstract: supplying fuel coals through a lower fluidized bed; reburning after collecting unburned fine particles scattered from the lower fluidized bed in an upper fluidized bed by the effect of whirling flow; continuously discharging ash contents to keep steady the solid hold-up in the upper and lower fluidized beds; adjusting operating temperature and air-blowing ratio in the upper and lower fluidized beds; and recirculating the unburned fine particles into the upper or lower fluidized eds. The method enhances combustion efficiency to lower scatter-discharging velocity.
Patent KR-940011527-B1 (KR)
Title: Improve method diarkyl propanedi imidate dihydrohalaide
Inventor: PARK SONG-SOK
IPC: C07C251/38
Filed: 1991-03-18
Granted: 1994-12-20
Abstract: The dialkyl propanediimidate dihydrohalide of forula (I) [R = C1-4 lower alkyl; X = halogen  is prepared by reacting a malononitrile with ROH [R = C1-4 lower alkyl  and HX [X = halogen . Pref. a dimethyl propanediimidate dihydrochloride is prepd. by reacting a methyl alcohol, a malononitrile and an anhydrous chloric acid, filtering the precipitate, washing it with a methyl alcohol, and vacuum drying it. The compound (I) is useful as a starting material for the manufacture of a propeneimidate.

Abstract: Described herein is a process for dehydrohalogenation of substituted dihydropyridine dicarbothioate compounds.
Patent KR-930008042-B1 (KR)
Title: Microcontroller unit
Inventor: LEE BYONG-JUN
IPC: G06F9/26
Filed: 1991-04-03
Granted: 1993-08-25
Abstract: The memory can be selected by read/write  signals  and  reset signals, as external memory blocks  and  external  timing  control blocks, and internal memory access selective control  signals  are provided. This  includes  the  selected  memory  access  selecting signal emitting latch by receiving the interface control signal as it receives a  reset  signal  (to  reset)  for  the  internal  and external selective access of  the  memory  access  clock  emitting section.
