Title: Method of forming metal matrix composite bodies by a self-generated vacuum process and products produced therefrom
Inventor: KANTNER ROBERT CAMPBELL
IPC: C22C47/08
Filed: 1990-07-16
Granted: 1999-04-01
Abstract: The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, a suitable matrix metal (33), typically in a molten state, is in contact with a suitable filler material (31) or preform in the presence of a suitable reactive atmosphere in an impermeable container (32), at least at some point during the process, which permits a reaction to occur between the reactive atmosphere and the molten matrix metal (33) and /or filler material (31) or preform and/or impermeable container (32), thereby causing molten matrix metal (33) to infiltrate the filler material (31) or preform due to, at least in part, the creation of a self-generated vacuum. Such self-generated vacuum infiltration occurs without the application of any external pressure or vacuum.

Title: Recording method of optical media
Inventor: YO UN-SONG
IPC: G11B11/03
Filed: 1991-12-23
Granted: 1995-01-10
Abstract: The method for recording and reproducing reduces the signal transfer time by deleting the recorded signals during the pause time. The method comprises (A) executing either deleting or verifying the unrecorded sector in advance during the pause time which is not to record or reproduce the signals between CPU and magnetic optic disc drive; (B) only recording or reproducing the signals without deleting or vertifying the signals while recording or reproducing the signals.

Abstract: 축과 클러치 드럼간의 오일 통로 연결은 클러치 드럼을 축에 마운팅하는 스플라인에 작용하는 힘의 불평형을 의도적으로 제공함으로서 밀봉된다. 적어도 스플라인의 일부의 측부는 각이져서 클러치 드럼과 축간에 적용된 적어도 토오크의 일부가 방사상 부품으로 분리된다. 다른 스플라인수 또는 비대칭적인 스플라인의 위치 결정을 제공함으로서 함께 확고히 오일 통로에 인접한 축과 클러치 드럼의 측부를 강제하도록 정미하중이 설계된다. 이는 오일 통로의 양측상의 클러치 드럼으로부터 하나이상의 스플라인을 단순히 생략함으로서 성취된다. 그와 같은 구조에 대해 축상의 동일 스플라인은 통상 힘의 대칭적 분포를 필요로 하는 기어등의 마운팅에 사용된다.

Abstract: 본 발명은 추출 증류에 의한 부탄 및 부텐의 분리 방법에 관한 것이다. 
     주로 부탄과 부텐을 함유한 공급원을 가압하의 추출 증류 칼럼내에서 극성 용매(예를 들어, 디메틸 포름아미드)와 접촉시키면 상부에서 부탄이 회수된다. 부텐을 함유한 용매는 가압하의 두 번째 칼럼을 통과하는데, 이곳에서 부텐은 부분적으로 탈착되어 상부에서 회수된다. 여전히 부텐을 함유한 용매는 대기압하의 세 번째 칼럼내에서, 정제되며, 이의 용매-함유 증기 증류물은 압축된 후 두 번째 칼럼의 저부로 회수된다.

Title: Cell line for producing chimera antibody of hbv pre-s2
Inventor: HAN MUN-HUI
IPC: C12N15/51
Filed: 1992-05-04
Granted: 1995-08-29
Abstract: The chimeric antibody to pre-S2 of HBV (I) of subtype adr is prepared by; A (for heavy chain) (1) cutting DNA of aLys-30 of 8.9 kb with BanHI and BglII for HuCr1, (2) inserting that fragment into plasmid PSV2-neo to get PVS2neo-hCr1, (3) cutting DNA of pMHG-S2 of 9.4 kb and adding EcoRI linker, and (4) inserting that fragment into PVS2neo-hCr1 to get plasmid pHS2-neo (KCTC 0031BP); (for light chain) (5) extracting hygro gene from pSVhygro, (6) cutting pHuCk with EcoRI to get HuCk gene, (7) cutting pMGK-S2 with XmnI to get MuVk and Ek genes and adding XhoI linker, (8) inserting genes of (5), (6), (7) into plasmid pBluescript SK+ to get plasmid pLS2-hygro, C (KCTC 0032BP), (for transfectoma) (9) transfecting DNA fragments of PvuI treated pHS2-neo and SpeI/NotI treated pLS2-hygro to get A-44 (KCTC 0033BP). From A-44 transfectoma, 55kd size of heavy chain and 25kd of light chain of (1) were purified.
