Inventor: WHEELER ROBERT
IPC: B60W30/18
Filed: 1987-11-24
Granted: 1990-10-23
Abstract: The transmission system (10) has an operator actuated engine compression brake (17). The system senses vehicle deceleration and monitors throttle position (THL), vehicle brake actuation (BRK) and engine compression brake (ECB) actuation to select one of three mutually exclusive vehicle deceleration downshift profiles. The processing unit commands downshift in the third mode at engine speeds selected to result in insignficant vehicle engine braking. If during deceleration, either throttle position exceeds a set reference value or the compression brake is actuated, logic rules declare a performace/maximum braking condition. The shift profiles will result in the engine speed being at  maximun value upon completion of the downshift.

Abstract: 본 발명은 기판의 수직 방향으로 레이저 광을 발진하는 광을 발진하는 면발광형 도체 레이저 및 그 제조방법에 관한것이다. 
     면발광형 반도체 레이저, 이 레이저는 반도체 기판에 대해 수직인 공진기를 구성하는 반도체층의 적어도 클래드 층을 반도체 기판에 대해 수직인 1개 또는 복수개의 기둥모양 반도체층으로 만들고, 이 기둥 모양 반도체층의 주위에 - 족화합물 반도체 에피택셜층을 도포하여 구성된다. 
     복수개의 기둥모양 반도체층을 형성할 경우 그 사이에 분리옴을 형성하고, 이 분리홈에 - 족 화합물 반도체 에피텍셜층을 묻는다. 
     위상동 기형의 반도체 레이저를 구성할 경우에는 분리홈을 활성층까지 도달시키지 않는다. 
     분리홈에서 분리된 복수의 발광부에서 1개의 광속을 가진 비임직경이 큰 비임을 얻을 경우 출사되는 비임파장에 대해 투명한 - 족 화합물 반도체 에피텍셜층을 매립층으로서 이용한다. 
     또한 이 매립층 및 복수의 기둥 모양 반도 체층과 대항하는 에어리어에 걸쳐 광출 사측의 반사경을 형성한다.

Abstract: 불필요한 수지 자장성분이 실질적으로 없는 일방향 자장을 생성 가능한 영구자석 자기회로가 제공된다. 
     역극성의 한쌍의 주자극이 자력선을 생성하기 위해 영구자석체의 한쌍의 대향가장자리면에 배치된다. 
     가장자리면 사이의 자석체 주면은 채널로 제공되어 한쌍의 보조자극이 자력선의 중앙부를 제어하기 위해 채널의 대향 내측면부에 배치된다.
