Squeeze-film gas bearing technology

Squeeze-film bearing is studied to develop a low-friction suspension for the output-axis gimbal of a single-degree-of-freedom gyroscope. Included are a review of pertinent literature, the theory of squeeze-film lubrication, and design elements

Competitive Pressure on China: Factor Rewards Migration

Our objective is to assess personal income under perfect competition, when factors are rewarded according to their productivities, and to contrast the ensuing distribution with the status quo.Competition will yield winners and losers, both in terms of factor claims and in terms of regions or provinces. Income differences will press people to migrate.To analyze this, we divide China into 30 input-output sectors and 27 provinces; we maximize domestic final demand, while preserving its proportions in each province, subject to material balances and factor constraints.The shadow prices to the constraints represent competitive commodity prices and factor rewards.Unskilled labor would stand to lose and, therefore, inequality would mount.The pressure on interprovincial migration would be enormous with 10 to 20% of the people on the road.The flipside is the great potential for improvement of the average standard of living.competition;income distribution;migration

Reactively sputtered RuO2 diffusion barriers

The thermal stability of reactively sputtered RuO2 films is investigated from the point of view of their application as diffusion barriers in silicon contact metallizations with an Al overlayer. Backscattering spectra of Si/RuO2/Al samples and electrical measurements on shallow junction diodes with Si/TiSi2.3/RuO2/Al contacts both show that RuO2 films are effective diffusion barriers between Al and Si for 30-min annealing at temperatures as high as 600°C
