Filed: 1973-06-08
Abstract: 1429848 Detecting gases electrically HOCHVAKUUM DRESDEN VEB 8 June 1973 [9 June 1972] 27329/73 Heading G1N The partial pressure of inorganic and organic gases is determined by measuring the electrical conductivity of a single organic solid molecular compound exposed to the gases. The gases such as oxygen, hydrogen, carbon monoxide, carbon dioxide interact with the solid compound in a chemisorption process which changes the electrical surface properties and its conductivity. In one embodiment a cell is formed by depositing a pair of spaced metal electrodes on a quartz substrate and depositing a thin paste layer of all-trans-betacarotene over the electrodes and substrate. Alternatively a mono-crystal of all-trans-beta-carotene is applied to the substrate and then the spaced electrodes applied thereto. The cells so formed by be fastened to a P.T.F.E ring in the centre of which is a thermostatically controlled metal box in contact with the cell for maintaining its temperature constant. The P.T.F.E ring is supported by struts on a flange. The electrode leads are connected in series with a source of D.C., and measuring amplifier which latter is connected to an indicator.

Title: Thyristor with surface emitter layer - has several sections over emitter-base pn-junction with different impurity concentrations
IPC: H01L29/08
Filed: 1974-12-04
Abstract: The thyristor is designed for taking up relatively rapidly increasing blocking voltages without impairing its characteristics. Its surface emitter layer bounds a base layer of opposite conductivity, between which is formed a pn-junction. Over the latter are distributed special sections in which the value of the impurity concentrations differs from that in the remaining regions. The highest impurity concentration of the part of the base layer bounding the pn-junction is so low that these parts of the base layer are prevented from degeneration. The highest impurity concentration in these parts of the base layer is approximately 5.1018 atoms per cu.cm. The pn-junction in the specified sections is underneath the thyristor surface, differing from the pn-junction depth in the remaining regions.
