본 논문은 LCD 제조 공정 라인에서 LCD용 원판을 다른 여러 공정으로 이송하는데 사용하기 위한 수평형 스토크 시스템의 설계 및 제작에 관한 연구이다. 구동원으로 제작된 영구 자석 여자 횡자속형 전동기는 높은 공극 자속 밀도를 얻을 수 있는 구조로 일반 선형 유도 전동기나 선형 등기기에 비해 단위 체적당 높은 출력 밀도를 얻을 수 있는 장점을 가지고 있다. 3차원 등가 자기 회로망법을 사용하여 기자력 변화에 따른 추력 및 흡인력과 같은 특성을 해석하였으며 정특성 실험을 통하여 설계 및 해석의 타당성을 검토하였다.

It is desirable to monitor the vital signals, such as ECG, of a emergency patient during transfer in the hospital as well as in the ambulance. The purpose of this study is to develop a system which provides a real-time and wireless ECG to the medical staff nearby patient during transfer in hospital. In this context, we developed a low-power, low-cost and portable ECG system consisting of 1) ECG measurement and RF transmission module and 2) RF receiving and LCD display module. The developed system is expected to be useful in monitoring ECG of a patient during transfer in the hospital.

This paper describes an improved design model that can be used to configure a non-contact pneumatic device to turn a large sheet at the in-line system. For rotational moving in the conveyor system, the conventional method is to turn the system itself. The improved non-contact pick-up system mainly uses 8 pairs of L-shaped latches and 12 swirl type heads. It is positioned above the upward air flow table. This system performs the non-contact gripping and side-edge contact support in the vertical and rotational directions to hold the self-weight of a large flat sheet. A non-contact air head can exert a sufficient gripping ability at 4N lower than the standard working pressure. The side latches support 60% of the lifting force required. Through structural and flow analysis, the working conditions were simultaneously considered in accordance with the deflection and flatness of the glass.
