Title: Mobile process and appts. for removing metals from solids - or aq. suspensions or liq(s) comprising units connected together
Inventor: SCHLUTTIG ALEXANDER DR
IPC: C02F11/00
Filed: 1990-08-21
Abstract: In a mobile process and appts. for (dis)continuous removal of metals, esp. heavy metals, from solids, aq. suspensions and solns., the units are connected together in such a way that the mobile process has advantages over discontinuous and stationary processes and appts. ADVANTAGE - The plant is mobile, for use on land or water and can be installed on trucks, trains or ships. It consists, as wished, of one compact unit or several (pref. 6) mobile sub-units. Sol. metal cpds. can be leached from sludges. The quality of the metal removal is independent of the concn. and combination of the heavy metals. The process is operated in a closed cycle, the prods. are smeltable metal salts and metal-free solid mixts., with no waste prods. which have to be deposited. Metal removal may be in situ e.g. in wet dock. The productivity w.r.t. unit of time, is greater and several consumers can use one disposal unit together. The process can be optimised in continuous operation by including sensors, coupled to a computer, for continuous determn. of metal, allowing also of recycling of insufficiently treated prod.

Title: Masking of burst type errors in PCM digital audio signals - expanding signal section in time domain followed by smooth bending and recombination of signals
Inventor: BARBERIS MARC DIPL ING
IPC: G11B20/18
Filed: 1990-11-06
Abstract: An audio signal transmitted in digital form has a periodic pattern and within a specific interval (F) can contain distortions resulting in errors. A masking process is used to eliminate the signal distortion section (C) from the signal. On either side of the section there are regions defined as blending periods that allow a smooth transition to be obtained. Over the blending periods the signals are linearly weighted (d) to allow a smooth recombination to be obtained and an accurate reproduction of the original is achieved. USE/ADVANTAGE - E.g. for satellite radio broadcasting. Improved correction quality without introduction of noise.

Title: Reduced effect of contact-window mis-alignment in integrated circuits - using spacer technique inside the contact window to restrict interaction of interconnect layer with diffusion to a smaller area
Inventor: MOTONAMI KAORU
IPC: H01L23/485
Filed: 1990-11-12
Abstract: In a contact window (103), formed by etching through an insulator layer (2) to allow contact between the metallisation-layer (191) and a diffused region (113), pref. containing a lightly doped drain (LDD) region, resistant spacers (151) are present. The spacers restrict the area of interaction between the metallisation layer and the diffusion to the central region of the contact. The spacers are pref. made of a conductive or an insulating material, pref. undoped polycrystalline Si. The metallisation layer pref. consists at least partly of a doped poly-Si layer, while the spacers present a higher resistance to diffusion of these impurities than the substrate does in vertical direction. Also claimed is a metallisation layer contg. a refractory metal. In this case the spacers prevent interaction between the metal and the substrate except in the central area of the contact. The spacers are pref. mfd. by deposition of a poly-Si layer over the device surface after the contact window formation and controlled anisotropic etch-back. The metallisation layer is then completed by deposition of an undoped poly-Si layer followed by doping, of a doped poly-Si layer or of a refractory metal layer. USE/ADVANTAGE -The spacers reduce the lateral diffusion or soliciding in the contact window, which allows the contact window to be placed closer to the LDD region or allows increased alignment tolerance. The contact window pref. has a ratio of dia. to layer-thickness of not more than 1. The spacer width from window edge to edge of the spacer is 150-200 nm. The process is used in the mfr. of Si integrated circuits, pref. DRAMs.
