Title: Process for preparing core-shell particle dispersions
Inventor: MARTIN VOGEL
IPC: C08F2/22
Filed: 1987-10-31
Granted: 1995-07-31
Abstract: An aqueous dispersion of water-insoluble core-shell particles is prepared by emulsion polymerization for use as an opacifying agent in coatings. The particles have interior cores which are swollen with nonaqueous solvent. The polymeric exterior shells have a glass transition temperature greater than about 50 DEG C in the presence of the nonaqueous solvent. The partition coefficient for the nonaqueous solvent between the interior core polymer phase and the exterior shell polymer phase is at least about 1.25. Coatings compositions formulated using the core-shell particles show increased opacity, as single light scattering microvoids are formed in individual particles when the solvent evaporates and the core collapses inside the rigid exterior shell. Opacity develops even when aqueous coatings containing the particles are dried under high humidity conditions.

Abstract: 본 발명은 기판의 수직방향으로 레이저광을 발진하는 면발광형 반도체 레이저에 관한 것이다. 
     면발광형 반도체 레이저는 반도체기판에 대하여 수직인 공진기를 구성하는 반도체 층의 적어도 콘택트층 및 클래드층을 반도체기판을 대하여 수직인 1개 또는 여러개의 기둥형 반도체층으로 하고, 그 기둥형 반도체층 주위에 Ⅱ-Ⅵ족 화합물 반도체 에피택셜층을 메워서 구성된다. 
     광출사측의 전극은 기둥형 반도체층의 콘택트층과 접촉하여 형성되는 동시에 광출사구를 확보하기 위한 개구가 형성되고 이 개구에 광출사측의 반사경이 형성된다. 
     개구는 콘택트층의 기하학적 중심을 포함하는 범위이며 콘택트층 표면적의 10%이상 90%이하의 범위에서 형성된다. 
     위상동기형의 반도체 레이저이고 분리홈에서 분리된 복수의 발광부로부터 하나의 광속을 지닌 비임직경의 커다란 비임을 얻는 경우 출사되는 비임파장에 대하여 투명한 Ⅱ-Ⅵ 족 화합물 반도체 에피택셜층을 매립층으로써 이용한다. 
     또한 복수의 기둥형 반도체층 및 그 사이의 매립층과 대향하는 영역에 걸쳐서 광출사측의 전극의 개구를 형성하고 이 개구에 광출사측의 반사경을 형성한다.

Title: Ferrite bead chip
Inventor: LEE HYONG-JIN
IPC: H01F1/00
Filed: 1991-10-25
Granted: 1995-02-02
Abstract: Ferrite bead chip used for noise-reduction filter has a simple structure. The impedance of the manufactured chip has a low scattering in its value less than 5%. The chip consists of a ferrite core (1), an electrode (2) inside the core, and caps (3) at both ends of the ferrite core. The manufacturing method has the steps of inserting the electrode with a coating of epoxy adhesives into the ferrite core (1), bonding the electrode and core by heat-treatment, putting caps at the ends of the core, and finally spot-welding the caps and the core.

Abstract: 본 발명은 연속동제련방법을 개시한다. 
     우선, 용련로와 분리로와 전환로와 용련로, 분리로, 전환로를 직렬로 접속하는 용탕홈통과 복수의 양극로와 양극로와 전환로를 접속하는 조동홈통을 설치한 후 용련로내의 동정광을 도입하여 동정광을 용해, 산화하여 매트와 슬래그의 혼합물을 생성하고 그 혼합물을 분리로에 수용하여 슬래그로부터 매트를 분리한다. 이어서 슬래그로부터 분리된 매트를 산화하여 조동을 생성한 다음에 조동홈통을 통해 한족의 양극로내로 조동을 유동시켜서, 양극로내에서 보다 고품위의 동으로 정제한다. 
     양극로에서의 정제처리시에, 조동수용공정과 산화공정은 적어도 부분적으로 중복하는 방식으로 행해진다.

Title: A radioactive iodine compound for labeling an antibody
Inventor: YAMAUCHI AKIRA
IPC: C07D207/40
Filed: 1991-11-30
Granted: 1999-05-01
Abstract: The radioactive iodine compound of this invention or an intermediate for preparing the compound is represented by the following formula (I): <CHEM>  wherein R is H or <1><2><5>I. The radioactive compound can readily introduce a radioactive isotope element such as <1><2><5>I into an antibody molecule without damaging the activity of the antibody molecule. Therefore, the compound can preferably be used to label an antibody of immunoradiometric assay, and allow a higher degree of measurement sensitivity.
