Patent KR-850000190-B1 (KR)
Title: Process for preparing polyolefin layer
Inventor: PEERLKAMP ERIK RIJKELE
IPC: B32B27/08
Filed: 1981-08-31
Granted: 1985-03-05
Abstract: In the prodn. of a hollow molding, esp. a surfboard comprising a polyolefin outer shell and polyurethane foam core, the improvement is that the shell is made by forming a surface layer of stabilized polyolefin and another layer of unstabilized or slightly stabilized polyolefin inside the surface layer. The surfboard is suitably made by rotational molding, improved adhesion being obtd. between the polyolefin layer and polyurethane foam. Polyolefin layers can be easily repaired by melt-welding when damaged, which cannot be carried out using crosslinked material.

Title: Shearing machine
Inventor: MINATO YOSHIHARU
IPC: B23D15/12
Filed: 1982-05-26
Granted: 1989-04-11
Abstract: This shearing machine has stationary lower blades to cooperate with upper blades on a ram oscillating up and down about an eccentic shaft carried between slide plates forming a frame.  The ram, movable along the shaft, is pulled by a spring to widen the horizontal clearance between the blades.  The spring is attached to a rod held in an arcuate slot in the side plate.  Lead screws rotatable in nuts fixed to the plate act on blocks secured to the ram and slidable in apertures in the plate.  The lead screws are rotatable by means of a hand wheel and transmission to increase or decrease the horizontal clearance between the blades.

Title: Method and device of cleaning wire
Inventor: GOUQH ROBERT PETER
IPC: B21C43/04
Filed: 1983-08-09
Granted: 1988-11-26
Abstract: The cleaning method for elongate strip e.g. metal rod or wire comprises passing the material through a die which is dimensioned to provide a working clearance.  The strip is held under tension e.g. by a pair of feed rolls (12,14).  Transverse vibratory movement of the wire or rod is generated e.g. by a snail cam (18) rotated on a shaft (20) to periodically contact the material. This causes a number of points around the strip to contact the die.  A fluid is passed through the die, e.g. via supply lines (26), to displace material removed from the strip surface.  The strip can instead be vibrated electromagnetically.

Abstract: Tissue plasminogen activator (t-PA) zymogens and variants are prepared, including a fibrinolytically active variant of t-PA that has an amino acid alteration at a site within the protease domain of t-PA as compared with the corresponding wild-type t-PA, which alteration renders the variant zymogenic in the presence of plasmin-degraded fibrinogen, and/or fibrin (or plasma clot) specific, as compared to the corresponding wild-type t-PA. DNA sequences can be prepared that encode the zymogens and variants, as well as expression vectors incorporating the DNA sequences, and host cells transformed with the expression vectors. The zymogens and variants may be used in a pharmaceutical preparation to treat a vascular disease or condition or to prevent fibrin deposition or adhesion formation or reformation in mammals.

Abstract: 본발명은 고집적 반도체 소자의 자기정렬콘택 제조방법에 관한 것으로, DRAM셀의 비트라인 또는 전하저장전극 콘택형성시 콘택면적이 축소되어 콘택저항이 증대되는 것을 방지하기 위하여 실리콘 기판 상부에 게이트 산화막 및 절연층이 하부 및 상부에 구비되는 다수의 게이트전극을 형성하는 단계와, 상기의 구조를 포함하는 전체구조 상부에 내부산화막을 도포하고 액티브 오픈마스크를 이용하여 게이트전극과 게이트전극 사이의 내부산화막을 비등방성 식각으로 내부산화막을 제거하여 실리콘 기판을 노출시키는 동시에 게이트전극 측벽에 내부산화막 스페이서를 형성하는 단계와, 상기 노출된 실리콘 기판 상부의 콘택영역에 소정두께의 폴리실리콘층 접속매체를 형성하는 단계와, 전체구조 상부에 두꺼운 내부산화막을 도포하고 에치백 공정으로 상기 절연층의 소정상부에서 평탄하게 하는 단계와, 콘택마스크를 이용하여 폴리실리콘 접속매체를 노출시키고 비트라인 또는 전하저장전극을 형성하여 상기 폴리실리콘층 접속매체를 통하여 하부실리콘 기판에 콘택시키는 단계로 이루어지는 기술이다.

Abstract: The method for measuring the gap between the front panel  and shadow mask of the cathode  ray  tube  without  contact  comprises steps: (a) measuring and calculating the gap  with  the  reflected laser beam;  (b)  measuring  and  calculating  the  gap  with  the reflected laser beam; (b) comparing and compensating the  measured value to the reference one in the CPU; and  (c)  welding  the  gap with the compensated value. The apparatus comprises  a  number  of laser sensors (22) measuring the gap distance, a  digital  display (24) indicating the measured  value,  a  CPU  (25)  comparing  the measured value to the reference one and compensating the  measured one, and a welder controller (26) controlling the welder with  the compensated value.

Abstract: forming an etch stop layer on a semiconductor substrate; coating a first material on the etch stop layer, selectively etching the first material layer using a first mask pattern for forming a storage electrode to form a first pattern; coating a second material to fill the groove placed between the first patterns, selectively etching the second material layer to form a second pattern; removing the first and second pattern, forming a first conductive layer on the overall surface of the substrate; removing the first conductive layer placed on the remaining second material layer to define the first conductive layer into unit cells.
