摘要： A desuperheater control system for use in a refrigeration apparatus includes a thermostatic expansion valve which responds to the temperature and pressure at the outlet of a desuperheater for bypassing refrigerant flow from the condenser back to the suction side of the compressor. A pressure chamber is connected to the outlet of the expansion valve to sense the pressure therein. A water regulating valve is responsive to the pressure in the pressure chamber for regulating the water flow through the desuperheater so that the superheated refrigerant gas from the compressor is cooled to a pre-selected temperature having a minimum superheat.

摘要： An adaptive position control system including X, Y and .theta. stages and their associated positioning and motion detection apparatus, position detection apparatus for detecting the position of the stages relative to a fixed reference, X and Y position control subsystems responsive to signals developed by the motion and position detection apparatus and operative to generate coarse mode and precision mode drive signals for application to the X and Y stage positioning apparatus, X and Y adjust subsystems for enabling adjustment of the position detection apparatus, and a .theta. adjust subsystem operative in a coarse mode and precision mode for adjusting of the angular orientation of the .theta. stage. Operator control input to the various subsystems is accomplished by means of a joystick control mechanism and central processing unit.
