Title: Process for preparing solid nifedipine preparation of high bioavailability and with sustained effect
Inventor: ROSSI PIERGIORGIO
IPC: A61K47/34
Filed: 1986-10-15
Granted: 1994-07-16
Abstract: The object of the present invention is a process which permits the increase of the bioavailability in the solid formulations of nifedipine and its derivatives. In consists in dissolving the active substance together with a polyethylene glycol, in a common solvent, then absorbing this solution on a micronized, inert excipient, soluble in the gastrointe­stinal juices, and finally, co-precipitating the active substance and the polyethylene glycol by evaporating the solvent.The very large surface of the excipient on which the solution is absorbed, and the presence of polyethylene glycol, wich facilitate the homogeneous distribution of the solution on this surface, permit the active substance to precipitate and become very fine particles.The same results may be also obtained by blending homogeneously the micronized inert excipient with micronized nifedipine, and causing the mixture to be absorbed on a solution of polyethylene glycol, which by subsequent solvent evaporation, precipitates in fine particles that are homogeneously dispersed and in intimate contact with the active substance.Forms of solid dosage prepared with the mixture thus obtained, have shown a bioavailability higher than similar formulations already on the market.

Title: Optical writing materials

IPC: G11B7/243
Filed: 1989-07-31
Granted: 1993-10-08
Abstract: The high repeative  recording  and  playing  ability  can  be obtained by the  addition  of  Si  on  the  existed  TbFeCo  group recording layer. The addition of Si can  stabilize  the  value  of CNR; on the other hand, it has disadvantage that the CNR value  is decreased. This disadvantage can be removed by addition of  Gd  on the non-s-state; i.e. the high CNR can be achieved. The  25  %  of the overall recording layer is Tb and Gd  and  only  the  relative ratio of Tb and Cd can be changed. Because  of  high  conservative magnetic force, the 25 % ratio is chosen.

Abstract: 내부 연소 엔진(10)에 연결된 연료 및 공기 혼합가스로 연료 공기비 조절 방법은 엔진과 관련된 배기 가스 촉매 변환기(16) 가스 저장 용량에 고려할 문제를 주며, 변환기에 의한 변환 정도는 배기 가스내의 산소 성분에 의존한다. 따라서 상기는 상기 변환기에 의해 공급되며 저정된 산소에 의해 영향을 받으며, 촉매의 변환 정도는 연료 공기비의 목표 향상 또는 웨이킹에 의해 최적화 된다. 이러한 목적에 대해서, 공기 넘버 λ에 대한 측정값과 목표 값 λs 사이의 차가 결정되며 이차의 적분 함수 값은 조절기(13)에 의한 프리셋값(IS)을 향한 시간의 함수로서 조절된다.
Patent KR-940002342-B1 (KR)
Title: Circuit for displaying error states of unit microcomputer
Inventor: KIM SONG-SU
IPC: G06F15/16
Filed: 1991-01-18
Granted: 1994-03-23
Abstract: The information of abnormal state in unit-Micoms is displayed with a LED displaying unit to supply the efficiency of A/D conversion. The display circuit has an oscillator (50) for generating the specified frequency, a divider (40) for generating the specified clock signal, a control signal generator (10) for outputting the control signals (y1,y2) corresponding to the abnormal state, an LED display unit (70), a logic arithmatic unit (60) for driving the LED, a 7 segment decoder (20) for driving the abnormal state display unit (30), gate means (G1,...,G16) for controlling the error state signals (A0-A3,B0-B3,C0-C3) of Micoms (A,B,C) and decoders (DCD1,DCD2) for driving the gate means.
Patent KR-0181949-B1 (KR)
Title: Nonextruded concentrates of additives, fillers or pigments
Inventor: BARBI GIAMPAOLO
IPC: C08K7/22
Filed: 1991-05-14
Granted: 1999-05-15
Abstract: Nonextruded concentrates in particle form, each particle comprising:     A) a matrix consisting of a nonextruded particle of an olefin polymer or copolymer, having a porosity, expressed in percentage of voids on the volume of the particle, higher than or equal to 15%; B) one or more additives, pigments or fillers, or combinations thereof, deposited on the surface of the matrix (A) and/or inside its pores. The concentrates are used in the processing of polyolefins. n
