摘要： The invention relates to an infrared gas analyser (1), especially for use as a gas detector for leak detection using a sampling probe. Said gas analyser comprises a vessel (test vessel 2), through which a test gas flows, and an infrared light source (4, 5, 42) which produces an infrared light that shines through the test vessel (2). The analyser further encompasses a detector (35) that facilitates measurement of the infrared light absorption in the test gas. The aim of the invention is to provide at low costs an analyser that is apt for every day use. To this end, a reference vessel (3) through which a reference gas flows is provided in addition to the test vessel (2) through which the test gas flows. A reference gas is sucked from the environment of the test gas suction area. The same or an additional light source (4, 5, 42) and the same detector (35) are allocated to said reference vessel. The analyser is provided with means (38, 41) that effect a modulation of the infrared light shining through the vessel (2, 3). Means (36) are provided which produce the measured values and which allow that the background signals obtained by the infrared absorption in the gas of the reference vessel (3) are taken into consideration for the signals obtained by measuring the infrared absorption in the test vessel.

摘要： The memory cell configuration has a large number of memory cells provided in a semiconductor substrate and having bit-line trenches which extend in parallel in the longitudinal direction in the main face of the semiconductor substrate, at the bottoms of which in each case a first conductive region is provided, at the peaks of which in each case a second conductive region of the same conduction type as the first conductive region is provided, and in the walls of which in each case an intermediately located channel region is 0 provided; and having word lines which extend in the transverse direction along the main face of the semiconductor substrate, through specific bit-line trenches, to activate transistors provided there. An additional dopant is introduced into the trench walls of the bit-line trenches which are located between the word lines, in order to increase the corresponding transistor turn-on voltage there to suppress leakage currents.

摘要： Method for operating, a helium leak indicator (1) consisting of a helium detector (4) with evacuation devices comprising at least a high-vacuum pump (6), a backing pump (9) and a valve (16) whose level of flow conductance can be adjusted and serves to modulate the through-flow of test gas to be analyzed; in order to influence the sensitivity in a simple manner, the method provides that the modulation properties be changeable in such a manner that the effective pumping capacity at the inlet of the leak indicator is changed by the adjustment of the modulation properties.
