Electrostatic office copiers may be converted to digital data printers by adding a modulated hene laser and raster scanning while retaining the charging station, toning station and phtoceptor drum.the majority of present office are se-based photoceptors, but the speed is limited due to the… More

In order to meet the accelerating market demand for vlsi semi-conductor memory and logic circuits, it appears as though magnetically confined plasmas are required in order to attain anisotropic etching at a high rate. current high-pressure plasma systems etch with a high rate but with poor feature… More

Thermal management has become a major design constraint in electronic and high-precision devices as they are miniaturized and their performance is increased. in applications where passive (conduction) cooling is required, the device designer is faced with the dilemma of choosing a material that has… More

Silicon nitride powder has substantial advantages over other ceramic powder for applications such as cutting tool inserts, rotary shafts for turbines, and engine valves. consequently, the market demand is expected to increase from 250,000 lbs to 2.5 million lbs annually by 1995, provided an economic… More

Hydrogenated amorphous silicon (a-si:h) is a revolutionary new semiconducting material that can be deposited over large areas at relatively low cost, and is particularly suited for applications such as large-volume photodetectors in high energy physics accelerator projects. perez-mendez and others… More
