Abstract: Manganese oxide particles and lithium manganese oxide particles have been produced with an average diameter less than about 500 nm. The particles have a high degree of uniformity including a very narrow distribution of particles sizes. Methods are described for producing metal oxides by performing a reaction with an aerosol including a metal precursor. In particular, the particles can be formed by laser pyrolysis. The lithium manganese oxide particles can be formed by the heat treatment of nanoparticles of manganese oxide. Alternatively, lithium manganese oxide particles can be formed directly by laser pyrolysis. The lithium manganese oxide particles are useful as active materials in the positive electrodes of lithium based batteries. Improved batteries result from the use of the uniform nanoscale lithium manganese oxide particles.

Abstract: 본 발명은 짧은 톱니, 전이 톱니 및 적어도 하나의 긴 톱니를 구비하는 종류의 기어를 개시한다. 긴 톱니의 단면은 호크 비크 형상이며, 긴 톱니의 형상은 볼록부, 팁부, 오목부, 및 안내부에 의해 연속으로 부드럽게 연결된다. 긴 톱니의 2개의 측면은 긴 톱니의 양면 상의 짧은 톱니와 이웃하는 전이톱니를 각기 구비한다. 본 발명에 따르는 치합기어 쌍은 유체 누출의 감소, 로터의 내부 힘의 상쇄, 진동 및 소음의 최소화의 이점을 갖는다. 또 본 발명은 하우징, 상부 엔드커버 및 하부 엔드커버를 갖는 케이싱을 구비하고, 액상 또는 기상의 유체를 전달, 압축 또는 팽창시키기 위한 유압장치를 개시한다. 본 발명에 따르는 하나의 구동로터 및 본 발명에 따르는 하나의 종동로터를 갖는 적어도 한쌍의 치합기어는 하우징 내에 수용된다. 그 결과, 로터 간의 누출이 감소될 수 있으며, 그로 인해 압축률이 향상될 수 있다. 그 밖에도, 작동 중에 과압축 및 저압축을 피할 수 있다.
