Granted: 1999-03-20
Abstract: A process for the stereoselective synthesis of [R]- and [S]-2,3-dihydro-1,3-dimethyl-2-oxo-1H-indole-3-acetonitriles comprises reacting racemic and 5-alkoxy-substituted (+/-)-1,3-dimethyloxindoles with a halogenated acetonitrile in the presence of a substituted N-benzyl cinchoninium, quinidinium, cinchonidinium, or quininium catalyst. The resulting alkylated oxindoles can be converted to primary amines by catalytic reduction in the presence of hydrogen gas. One of the primary amines, such as enantiomers of 3-(2-aminoethyl)-1,3-dihydro-1,3-dimethyl-5-methoxy-2H-indol-2-one, can be enriched by contact with a chiral tartaric acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The product can be used in the synthesis of stereospecific forms of physostigmine and related compounds having pharmaceutical activity.

Abstract: A method for manufacturing a layer of a laminated, disposable absorbent product (10), such as a fluid-permeable cover layer (12), an absorbent core layer (14) and a fluid-impervious backing layer (16) thereof, with a conparatively small amount of waste matter. The method conprises the steps of longitudinally cutting a continuous web (32) of starting material according to a cyclic pattern (34) constructed with line segments corresponding to the edge contour of the disposable absorbent product. The cutting operation divides the continuous web in two strips (36,38), each strip having a patterned longitudinal edge whose outline corresponds to the cyclic pattern. The strips are crossed and joined to one another in a parallel and in a phase relationship to form a compound web having longitudinal edges producing repeatedly the edge contour of the disposable absorbent product. The invention extends to integrating this method into an operation for manufacturing disposable absorbent products, and to an apparatus for carrying out the methods according to the invention and the resulting products. <IMAGE>   <IMAGE>

Granted: 1999-06-15
Abstract: In the field of regulation of cell proliferation, a method of inhibiting or preventing cell proliferation is disclosed. Rb, a stable protein encoded by the retinoblastoma gene (RB1), is synthesized at all phases of the cell cycle. Newly synthesized Rb is underphosphorylated during the G0 and G1 phases but is phosphorylated at multiple sites at the G1/S boundary and during S phase. HL-60 cells lose their ability to multiply phosphorylate newly synthesized Rb when induced to terminally differentiate by chemicals such as dimethylsulfoxide, retinoic acid and butyric acid. A method of using these chemicals to inhibit or prevent cell proliferation in cells containing Rb is disclosed.

Abstract: PURPOSE: A polymer dispersed liquid crystal(PDLC) is to provide a wide viewing angle, to improve light utilization efficiency without utilizing a polarizing plate and to eliminate an alignment process, thereby facilitating a manufacturing process. CONSTITUTION: A polymer dispersed liquid crystal composition is prepared which is composed of 1 to 40 wt% of acrylate-series monomer-oligomer comprising a crosslinking agent, 0.1 to 20 wt% of diacrylate derivative monomer having a structure similar to that of a liquid crystal to be added, 0 to 20 wt% of a cholesteric liquid crystal and 50 to 98wt% of a nematic liquid crystal. A small amount of UV initiator is added to the composition to polymerize it, thus obtaining the PDLC. The PDLC is injected between the glass plates with a coating of indium tin oxide thereon, and is exposed to UV radiation to cure it. When the UV curing is completed, the PDLC develops a focal-conic structure, so that a liquid crystal cell becomes opaque, whereas the cell turns into a homeotropic state and it becomes transparent when an electric field is applied thereto.

Abstract: 본 발명은 난방운전에 의한 실내공기 조화시, 실내온도를 감지하고 실내공간의 면적을 산출하여 이들을 설정온도 및 기준면적과 비교하여 풍량을 제어하는 공기조화기의 풍량제어방법에 관한 것이다. 본 발명에 따른 공기조화기의 풍량제어방법은 공조공간의 제1실내온도(Ti)를 감지하는 실내온도감지단계(11); 공조공간의 공기조화기로부터 벽까지의 거리를 감지하고, 이 감지된 데이터에 기초하여 면적을 산출하는 실내면적 산출단계(15); 제1실내온도(Ti)를 설정온도(To)와 비교하고, 산출된 실내면적(M)을 제1설정면적(S1) 및 제2설정면적(S2)과 각각 비교하는 제1, 2온도 및 면적비교판단단계(16, 18); 면적 및 온도 비교판단단계(16, 18)에서의 비교결과에 따라 풍량을 강, 중, 약으로 제어하는 풍량제어단계(17, 19, 20); 풍량제어운전중에 제2실내온도(TS)를 감지하여 제2실내온도(TS)와 설정온도(To)를 비교하는 온도판단단계(21); 온도판단단계(21)에서의 비교결과 실내온도가 설정온도보다 높으면 운전오프신호가 입력되었는지를 판단하는 운전오프신호입력판단단계(22); 상기 단계 (22)의 판단결과, 운전오프신호가 입력되었으면, 운전을정지하는 운전정지단계(23)로 이루어진 것을 특징으로 한다. 따라서, 상기와 같은 본 발명의 제어동작에 따라 실내공간 전체가 골고루 설정온도로 유지될 수 있다.

Title: The method for preparation of vinyl sheet with cubic effect
Inventor: KIM JIN-HYUNG
IPC: B29D7/00
Filed: 1993-04-13
Granted: 1997-01-21
Abstract: A method for manufacturing the vinyl upper member having cubic effect comprising the first step manufacturing the semi-product which foam layers(2,6) are laminated on the upper and lower sides of the base layer(1) coating pastes in grass mat(GM); the second step uniformly arranging the first and second chip layers  by a pair of brushes(F,F-1); the third step stabilizing the chip layer(3) by a cooler(K); and the forth step stabilizing by appling UV coating layer(5) on the surface is disclosed. Thereby, it is possible to improve wear-resistance, chemical-resistance, luster and contamination-resistance.

Title: Process for purifying ubns4e1e2 protein
Inventor: CHO JOONG MYUNG
IPC: C12P21/00
Filed: 1993-04-28
Granted: 2000-12-15
Abstract: PURPOSE: Provided is a method for purifying recombinant protein UBNS4E1E2 in a high yield which is useful in developing vaccines against hepatitis C virus and diagnosing hepatitis C more correctly. CONSTITUTION: The method for purifying recombinant protein UBNS4E1E2 is comprised of the next steps of: i) destroying E. coli where recombinant protein UBNS4E1E2 is expressed; ii) washing cell sediments with buffer solution containing triton X-100 and centrifuging it; iii) washing insoluble protein pellets with buffer solution containing urea and centrifuging it; iv) washing insoluble protein pellets with buffer solution containing guanidine hydrochloride; v) dissolving insoluble protein pellets in buffer solution containing SDS and centrifuging it; and vi) performing S-300 gel permission chromatography with obtained supernatant.
