Abstract: 사설교환기 시스템의 타임 스위칭 방법에 관한 것이다. 
     메모리를 구비한 사설교환기의 타임 스위칭 방법에 있어서, 
     자신의 가입자가 다른 가입자와 공유하게 될 하이웨이 번호를 기입하고 있는 상기 메모리에서 해당 가입자가 가지고 있는 하이웨이 번호를 억세스하여 상기 하이웨이가 가진 다수의 채널 중 비어 있는 채널 유무를 조사하고, 상기 조사결과 비어 있는 채널이 있어 채널을 배정 받을 경우 가입자 송신 채널과 DTMF 리시버 채널을 연결함과 동시에 가입자 수신 채널과 톤공급회로 채널을 연결하고 다이얼된 디지트를 받아들여 분석하며, 상기 분석 결과 착신측 착신하이웨이에 비어있는 채널이 있으면 발신자에게 호출음을 연결하고 착신자에게 링신호를 송출하여 착신자 응답이 있으면 발신자와 착신자의 채널을 타임스위치를 통해 통화로를 연결하도록 함으로써 한 하이웨이에 배당되는 가입자의 수용율을 증가함으로써 시스템의 확장이 용이해지고, 통화량에 따른 가입자의 수용으로 통화의 질을 높인다.

Abstract: 트랙션 슬립 제어를 나타내는 차량용 회로 구성 
     가변 제어 문턱 값(RS)은 기본 문턱 값(GS) 및 휘일 슬립 가속도로부터 유도된 부분으로 이루어진 제어 문턱 값을 갖는 브레이크 조종장치를 통해 트랙션 슬립 제어용 회로 구성으로 형성된다. 휘일 슬립(VR)은 제어 편차, 즉 제어 문턱 값(RS) 및 휘일 슬립(VR) 사이의 차이를 결정하기 위해 제어 문턱 값에 비교된다. 브레이크 압력 패턴(P)은 트랙션 슬립 제어 과정중에 휘일 슬립 가속도에 따라 제어된다.
