Title: Amorphous alloy for magnetic heads
Inventor: NAKAMODO MIKIO
IPC: C22C45/00
Filed: 1987-03-23
Granted: 1990-04-28
Abstract: Amorphous alloy for a magnetic head has a composition of the formula (Fe1-a, Co a) 100-e-f-bCre Ruf(Sic,Bd)b, where a is 0.930.95, c/c+d is 0.55-0.65, b is 22-27, e is 0.4-2.6 and f is 1.5-4.0.

Patent KR-0161660-B1 (KR)
Title: Abrasive product having binder comprising an aminoplast resin
Inventor: LARSON ERIC G
IPC: B24D11/02
Filed: 1989-11-22
Granted: 1999-01-15
Abstract: This invention relates to abrasive products having a resinous binder which holds and supports abrasive grains on a backing sheet or in a fibrous sheet. Generally, thermally curable binders provide coated abrasives having excellent properties, e.g., heat resistance. In order to obtain the proper coating viscosities, solvent is commonly added to these binders. When polyester backings are used, curing temperature is limited to about 130 DEG C, resulting in long cure times. The long cure time along with solvent removal necessitate the use of festoon curing areas. Disadvantages of festoon curing areas include the formation of defects at the suspension rods, inconsistent cure due to temperature variations in the ovens, sagging of the binder, wrinkling of flexible webs, and shifting of abrasive grains. Although radiation curable resins solve the problems associated with thermally curable resins, with respect to festoon ovens, radiation curable resins are generally more expensive than thermally curable resins. This invention provides an abrasive product comprising abrasive grains bonded together or bonded to at least one major surface of a backing sheet, by a binder formed from a precursor comprising an aminoplast resin having on average at least 1.1 pendant  alpha , beta -unsaturated carbonyl groups per molecule. The binder is formed by curing the precursor at the  alpha , beta -unsaturated site of the carbonyl group, by radiation energy or by heat, in the presence of an appropriate initiator system. The aminoplast resin can also contain pendant amino or hydroxy functional groups, which allow polymerization with condensation curable resins, such as phenolic, melamine, urea, urethane, and furfural resins. Polymerization at the unsaturated site of  alpha , beta -unsaturated carbonyl group can be effected either by radiation energy or by heat, and curing at the sites of the amino or hydroxy functional group can be subsequently effected by heat.

Abstract: 롤러측(4)상에 차례로 배열되어 롤러몸체 베어링의 방식에 따라 롤러축(4)상에서 롤러몸체(4)위로 회전가능하게 지지된 동일한 구조의, 다수의 외부부시(2)를 갖으며, 상기 외부부시(2)는 서로 접촉되지 않게 간격을 두고 있고, 박판 스트립 또는 박판웨브(21)는 외부부시(2)를 부분적으로 둘러싸고 있으며, 이로인해 외부부시의 원통형 외부면의 부분에 프리스트레스가 가해지는, 와인딩장치용, 특히 진공상태에서 플라스틱 웨브를 연속적으로 증발 또는 스퍼터링 하기 위한 장치용 스트립 및/또는 박판웨브의 안내 및 신장롤러에 있어서, 롤러축(4)의 종방향홈(17)내에 종방향으로 이동가능하게 지지되어 안내되는 사각형로드(18)가 설치되어 있고, 상기 로드는, 외부부시(2)에 할당된 수용부시(8)내에 지지되거나 이 수용부시와 일체로 형성되어 있으며 사각형로드에 간격을 두고 배치된 리세스까지 방사상 내부로 뻗은 적어도 하나의 볼핀(19)과 협력작용하고, 이로인해 사각형로드(18)의 종방향 이동은 한쌍의 저널 또는 볼핀(13,14)에 의해 기울어질 수 있도록 롤러축(4)상에 지지된 수용부시(8)를 롤러축(4)의 종축에 대해 선회시킨다.

Abstract: 분할면 중심선을 따라 원주형의 중공부를 갖도록 조합시킨 금형의 중궁부 양측 적정부위에 축심에 직교하는 방향으로 코어 프린트 성형을 위한 원주형의 오목부를 가지며, 상기 중공부의 축심을 따라 심봉을 끼워 그 주위에 원통형 공간을 갖는 코어 조형용 금형을 준비하는 제1공정과; 소정 온도로 가열된 상기 금형의 공간으로 주물사를 충진시킨 다음 그 금형의 분할과 심봉을 빼내고 그의 일측 관통부를 폐쇄시켜 코어를 얻는 제2공정과; 상기와 같은 코어의 일측으로 직경이 줄어드는 용적 변화부를 갖는 부위에 소직경의 파이프를 연결하고 그의 타단으로 코어 프린트를 조형한후 상기 소직경 파이프의 외주면에 도형재를 도포하여 완전한 코어를 얻는 제3공정과; 상기 코어를 캠축 주조용 주형의 캐비티내에 장치하고 중공 캠축 주조용 주형을 조립하는 제4공정과; 상기 주형에 주철 용탕 주입 응고시키고, 그 내부의 코어를 제거함과 동시에 소직경 파이프를 제거하여 캠축 주물을 얻는 제5공정으로 이루어지는 중공 캠축 주물의 주조방법을 제공함으로써, 중공부의 직경이 줄어드는 용적 변화형 코어(Core)의 제작이 용이하고, 주조시에 발생되는 가스의 배출이 용이함은 물론 탈사성이 우수하여 중공 캠축의 제조를 용이하게 할 수 있게 한 것이다.

Title: Warking method and road-shoulder wall for concrete road-shoulder
Inventor: KANG HAENG-ON

Abstract: A precast or site-poured concrete retaining wall is constructed to expand the width of the paved road toward the earth raised shoulder edge with an effect of reducing construction time and cost. The wall having an "L" section has a base plate portion (2) to be provided with tie-bars (7) on the upright wall having a portion to secure a guard rail post in insertion. The tie-bars are connected to the projective extensions of concrete reinforcing steel rods for concrete pavement of the expanding part of the road shoulder.
