Apparatus concentrates contaminants outgassing from specimens in vacuum and passes concentrated contaminants to gas-chromatography/mass-spectrometry system for analysis. Cold wall of collection chamber adsorbs gases from specimen in isot... WC Mahone 被引量: 0发表: 1990年 Characterization and monitoring ...
pressure at 270,000 meters (10−6mb) iscomparableto that in the best human-madevacuumever attained. At heights above 1,500 to 3,000 meters (5,000 to 10,000 feet), the pressure is low enough to producemountain sicknessand severe physiological problems unless careful acclimatization is ...
PURPOSE: To reduce weight, simplify structure, and achieve compactness by improving the retention of a vacuum chamber and improving the shielding of the vacuum chamber and an electronic circuit part for converting signal. ;CONSTITUTION: A vacuum chamber 8 is retained at the upper part of an elect...
Altitude (Low Pressure) Testingmakes use of a vacuum chamber to simulate the effects of high altitude conditions. The pressure inside the altitude chamber can be reduced to correspond to the air pressure at a specific altitude. Products can be placed inside the altitude chamber and tested to det...

A vacuum system, and a method of controlling the pressure of vacuum chamber and a vacuum processing system are provided to use even in case the power supply stops with the power outage by controlling the opening and shutting of the first switching tool by using the first control gas. A gate...
Controlling the pressure in the vacuum chamber (45) of a distillation- or sublimation unit comprises evacuating at a first (high) rate using a flow path (50) of low flow resistance then, the pressure in the chamber is measured. Flow through the first path is interrupted on reaching a boili...
