Granted: 1990-07-21
Abstract: Characteristics are measured of a sample based on its electrical properties. Firstly, an easily absorbing soln. material is impregnated with the sample which is obtd. from an object to be measured. The soln. material is chemically stabilized, flexible and emanates no interferential ingredient against the object to be measured. Finally, the soln. material is physically contacted with a measuring portion of a sheet-type ion-concn. device (I) for measuring the characteristics. Device (I) has an  electrode which is formed in part by an ion-responsive membrane, and also has a reference electrode. Both electrodes lie in the same plane for placement of the soln. material between them.

Abstract: 본 발명은 파이프 컨베이어의 파이프 라인계로(系路)에서 변각(變角)하는 코너 일부의 마모, 손상에 대한 보수를 하기 위하여 코너 보강 부재의 교환을 용이하게 함은 물론이고, 코너부에 보강부재를 설치하되, 코너부의 안둘레면에 형상변화가 없도록 하고, 요철을 형성하지 않도록 함으로써 피반송물의 걸림을 방지함과 동시에 반송수단의 이송을 스므스하게 한것을 특징으로 한다. 
     파이프 라인의 코너 안둘레쪽에 개구부(12)를 설치하여 이 개구부(12)에 블록 형상의 코너 보강 부재(14)를 부착하도록 하였다. 
     이 코너 보강 부재(14)는 일체의 블록으로 되어 있고, 상부 개구를 둘러쌓도록 하여 덮는 부착 케이스부(13)에 끼워 맞춤하여 고정되는 것으로 그 아래면은 코너부 안둘레의 만곡면에 대응한 만곡면으로 설정되어 있고, 교환이 가능하게 되어 있다. 
     또, 코너 보강 부재(14)로서 개구부(12)를 복수로 덮을 수 있는 단일형식의 코너 단위 부재(44)를 사용해도 된다. 
     이 코너 단위 부재(44)는 부착 케이스부(13)에 연결되는 누름 부재를 개재하여 개구부(12)를 맞도록 고정됨으로 부분적으로 교환이 가능하게 된다.

Title: Variable intake system
Inventor: CHOE MYUNG-SIK
IPC: F02B27/02
Filed: 1992-03-06
Granted: 1996-08-22
Abstract: The variable intake system enables an intake port to take various shapes according to the operating condition of engine for inducing the optimal intake flowing. A flexible tube(10) at the inside of an intake port(1) end expands or contracts by the ECU control. In case of low speed driving, the flexible tube is controlled to expand and lead intaking air into strong helical turbulence which is ideal for low speed driving. In case high speed driving, the flexible tube is controlled to contract and makes it possible to taking much of air in, which results in improved output power.

Abstract: 본 발명은 비축대칭 구면을 성형하는 방법 및 장치에 관한 것이다. 상기 장치는 θ좌표축 방향에서 Z축에 대해 작업홀더를 연속적으로 회전시키기 위한 θ축 회전 유닛을 제공한다. 
     상기 장치는 Z축에 수직인 Y축 방향에서 작업 홀더상의 작업물과 공구 홀더상의 공구사이에 Y축 비교 위치를 변경하는 Y좌표 변경 유닛을 포함한다. 작업 홀더상의 작업몰과 공구 홀더상의 공구사이의 Z축 비교 위치는 Z좌표 변경 유닛에 의해 Z축 방향으로 변경된다. θ축 회전유닛, Y좌표 변경 유닛 및 Z좌표 변경 유닛은 작업몰에 비축대칭 구면을 형성하도록 작업몰의 Y좌표와 θ좌표 및 Z좌표를 상호 비교하는 제어유닛에 의해 제어된다.
