Abstract: PCT No. PCT/HU91/00013 Sec. 371 Date Jan. 2, 1992 Sec. 102(e) Date Jan. 2, 1992 PCT Filed Mar. 28, 1991.The invention relates to inclusion complexes of 3-morpholino-sydnonimine or its salts or its tautomer isomer, process for the preparation thereof and pharmaceutical compositions containing the same. The inclusion complex of 3-morpholino-sydnonimine or its salt formed with cyclodextrin derivative is prepared by a) reacting the 3-morpholino-sydnonimine or its salt in an aqueous medium with a cyclodextrin derivative and the complex is isolated from the solution by dehydratation, or b) high energy milling of 3-morpholino-sydnonimine or its salt and a cyclodextrin derivative.

Abstract: 본 발명은 2개의 대향 배열된 도체 패턴을 갖는 전자총을 포함하는 음극선관에 관한 것이다. 작동시에 전자 비임은 도체 패턴사이에서 이동한다. 종래의 전자총의 전극에 의해 달성되는 전자 - 광학 기능, 즉, 전자 비임을 집중시키고 수렴시키는 것은 2개의 평면 도체 패턴에 의해 달성될 수 있다는 것이 발견되었다. 상기 도체 패턴은 정확히 제조될 수 있고 상호에 대해 정확히 배열될 수 있다. 이것은 복잡한 렌즈 시스템의 제조를 가능하게 한다.

Title: Structure of laser diode
Inventor: AN DO-YOL
Filed: 1992-04-03
Granted: 1994-12-03
Abstract: The laser diode structure is formed in such a manner that a metal layer is formed on a substrate; a source/drain is formed on the metal layer; an active layer made of a conjunctive quantum well is formed on the metal layer area between the source and the drain; and a gate is formed on the portion of the metal layer between the source and the drain to apply an electric field.
