Title: Sizing method of warp sizing machine
Inventor: HAN YONG-SOK
IPC: D02H5/02
Filed: 1986-02-06
Granted: 1987-10-12
Abstract: The emulsion of grey yarn(3) supplied from creels(2) is removed rapidly by a heating means(13) located in front of a sizing means(5).  The heating means may consisted of heating rollers or an assembly of hot water tank and dipping roller. Since the emulsion is removed by hot temperature, the peripheral temperature becomes high so that it improves the adhesiveness of the sizing liquid onto the grey yarn in the sizing means.

Title: Method and apparatus of valuation of safety
Inventor: KANNO SADOSI
IPC: G01M99/00
Filed: 1986-10-23
Granted: 1990-04-30
Abstract: The safety assessing method involves measuring a depth of a crack formed in a fitting portion of a fitted member and determining an opening displacement of the crack by an elastic-plastic fracture method.  A reduction in shrinkage fitting force is calculated based on the determined opening displacement.  The determined opening displacement and the reduced shrinkage fitting force of the fitted member with a predetermined standard are compared to thereby assess the safety of the rotor.  An allowable reduction in shrinkage fitting force which permits further operation of the rotor having a crack formed in it is set at half the initial shrinkage fitting force determined during operation without crack formation.

Abstract: 반도체장치 및 그 제조방법에 관한 것으로써, 박형의 패케이지로 하기 위해, 장방형상의 반도체칩의 회로형성면의 대략 중심영역에 얇은 금속박으로 되는 공용 내부리이드를 긴변방향과 거의 평행하게 고정하여 배치하고, 또 그 위에 프레임 형상의 여러개의 신호용 내부리이드 및 공용 내부리이드를 적층, 고정해서 수지로 봉한 것이다. 
     이러한 반도체장치 및 그 제조방법을 이용하는 것에 의해, 공용 내부리이드를 본딩와이어가 건너뛰는 일이 없어 단락할 위험이 없고, 다중 본딩이 가능하며, 반도체칩의 주면에서 본딩와이어의 정점까지의 높이를 낮게 할 수 있어 박형의 패케이지를 제작할 수 있다.
