Title: Method of processing several television signals for transmission and device
IPC: H04N7/08
Filed: 1991-02-08
Abstract: To process several television signals for transmission purposes, for example for an optical waveguide cable television distribution network, the television signals are converted group by group as frequency-division multiplex signal into a frequency position which is advantageous for subsequent digitising (AD). The frequency-division multiplex signal is digitised as a composite signal. Due to this processing, the complexity both at the receiver end and at the transmitter end can be kept down without noticeable deterioration in quality. At the receiving end, only one D/A converter (DAG) and one channel group converter (UG') is necessary for one group of channels of television signals. <IMAGE>

Title: Diamond neutron detector
IPC: G01T3/00
Filed: 1991-10-07
Abstract: A neutron detector is formed from a layer of polycrystalline diamond (12, 24, 40) which is deposited by a chemical vapour deposition process. The diamond material contains <1><0>B as a dopant, in a concentration of 1 000 ppm or less. In one embodiment, the layer of diamond material is deposited on a supporting substrate (10). Advantageously, the substrate itself may comprise a layer of diamond material. In another embodiment, the substrate comprises a layer of conductive or semiconductive material (22). The diamond material is deposited on top of the substrate, with at least two regions in contact with the semiconductive material. A central portion of the semiconductive material is etched away, and electrical contacts (26, 28) are applied to the remaining portions (22.1, 22.2) of the semiconductive substrate. An advantage of the neutron detector of the invention is that the diamond layer is very thin, less than 50  mu m thick, so that the sensitivity of the detector to other radiation, particularly  gamma  radiation, is reduced. <IMAGE>

Abstract: The present invention relates to method of manufacturing
semiconductor devices having built-in capacitor comprising a
dielectric substance of high dielectric constant or a
ferroelectric substance as the capacitance insulation film, and
aims to solve a problem that the prior art capacitance insulation
film contained in semiconductor devices has a rough surface which

in which method a capacitance insulation film is produced by first
forming a first dielectric film, and forming a second dielectric
film on the first dielectric film for a thickness greater than the
difference in level between top and bottom of the surface of first
dielectric film, and forming a thin film whose etching speed is
identical with that of the second dielectric film on the second
dielectric film making the surface of thin film flat, and then
etching the whole of the thin film and part of the second
dielectric film off simultaneously to make the surface of second

Filed: 1996-04-01
Abstract: The present invention provides compositions for inactivating thrombin bound to fibrin within a thrombus or clot, whereby the ability of clot-bound thrombin to catalytically promote further clot accretion is substantially diminished or eliminated. The compositions of the present invention are particularly useful for preventing thrombosis in the circuit of cardiac bypass apparatus and in patients undergoing renal dialysis, and for treating patients suffering from or at risk of suffering from thrombus-related cardiovascular conditions, such as unstable angina, acute myocardial infarction (heart attack), cerebrovascular accidents (stroke), pulmonary embolism, deep vein thrombosis, arterial thrombosis, etc. The compositions comprise agents which activate heparin cofactor II mediated inhibition of thrombin and having minimal affinity for antitrhombin III. Preferred agents are low molecular weight heparin preparations (MW of 3,000-8,000) prepared by depolymerising heparin using nitrous acid, oxidising the resultant product with periodate and reducing it with borohydride. The product has its non-sulphated uronic acid residues in open ring form and it substantially free of aldehyde groups.
