Abstract: A wafer cooling apparatus (10) characterized by a chamber (16), a pedestal (18) disposed within the chamber and a mechanism (20) for lowering a semiconductor wafer (88) onto an upper surface (60) of the pedestal (18). The upper surface (60) of the pedestal (18) is grooved to allow gas trapped between the wafer (88) and the pedestal surface (60) to escape around the periphery of the wafer, thereby minimizing the tendency of the wafer to "skate" across the surface of the pedestal on a thin layer of gas. The method involves extending a number of pins (74) through a grooved cooling surface (60) of the pedestal (18) to contact a wafer (88), and retracting the pins (74) into the pedestal to lower the wafer (88) to the cooling surface (60) and to force gas trapped between the wafer and the pedestal into the grooves (62) of the pedestal.

Abstract: A method is to be provided for checking for contaminants, in which expediently only one analytical system, for example a mass spectrometer, is required, to which the test air in question of each bottle is fed in succession. As a result, the overall expenditure for such a checking machine is to be reduced. This object is achieved by drawing in, during the analysis of a preceding bottle, a predeterminable amount of air from the next and/or further bottle, and keeping it in readiness within the system for subsequent direct in-feed to the analytical instrument and by feeding it to the analytical instrument after the preceding bottle has been checked and by then removing it from the system by inverting the flow direction and feeding in flushing gas. <IMAGE>

Abstract: Apparatus for imaging diseases in tissue comprising a light source for generating excitation light that includes wavelengths capable of generating characteristic autofluorescence for abnormal and normal tissue. A fibreoptic illuminating light guide is used to illuminate tissue with light that includes at least the excitation light thereby exciting the tissue to emit the characteristic autofluorescence. An imaging bundle collects emitted autofluorescence light from the tissue. The autofluorescence light is filtered into spectral bands in which the autofluorescence intensity for abnormal tissue is substantially different from normal tissue and the autofluorescence intensity for abnormal tissue is substantially similar to normal tissue. An optical system is used to intercept the filtered autofluorescence light to acquire at least two filtered emitted autofluorescence images of the tissue. The acquired images are displayed in real time on a display monitor in such a manner as to delineate abnormal and normal tissue.
