Title: Determining critical surface characteristics of mounting films for semiconductor wafers
Inventor: MILLER ANTON JOHANN
IPC: B24B37/04
Filed: 1994-11-23
Abstract: A method of improving the yield and achievable tolerances of integrated circuits by obtaining surface measurements of non-reflective soft mounting films used in integrated circuit manufacture. The non-reflective surface of a mounting film (14) is first rendered reflective by applying a reflective wafer (16) atop the film surface. This reflective test wafer, which is highly plano-parallel and preferably has a thickness less than that of the ultimate product wafer, is applied to the mounting film to be measured via direct pressure whereby the reflective test wafer conforms to and takes on the surface characteristics and contours of the film. The formerly non-reflective surface of the mounting film is thereby rendered effectively reflective and thus susceptible to optical profiling by a computerized interferometer in accordance with well-known techniques. The mounting film may then be critically applied during integrated circuit manufacture, during initial wafer forming and/or during chemo-mechanical polishing for layer planarization. <IMAGE>

The rod-like member produced by these crimping techniques may be over-wrapped to provide pockets (39) surrounding the crimped sections which may be filled with a smoke-modifying material, for example, activated charcoal particles. Discrete elements cut from the rod-like member may be used in cigarettes, such as in production of filtered cigarettes.
Patent GB-2324638-A (GB)
Title: Regulating a transport system
Inventor: ERRINGTON SIMON
IPC: B61L3/00
Filed: 1997-04-26
Abstract: Certain transport systems, particularly underground railways, are run according to nominal timetables. A problem with this approach is that perturbations in the service cause large time intervals to develop between some vehicles leaving other vehicles with little distance between them. This can cause overcrowding on eg. station platforms. A method of regulating a transport system, such as a railway system, comprises deriving a preferred departure time for a vehicle at a stopping-place, eg. a station 2, by means of eg. a train monitoring system 5 and a computer 3, located at a control site 1; and communicating the time to a driver of the vehicle. The departure time may be visually displayed, in the form of a countdown, on a television screen 12 located either on the platform of the station 2 or in the driver's cab.
Patent GB-2311378-A (GB)
Title: NMR sample cell
Inventor: ANDERSON WESTON ARTHUR
IPC: G01V3/14
Filed: 1996-10-16
Abstract: The present invention relates to improving the sensitivity of an NMR system for electrically conductive (polar) NMR samples. Many NMR samples use water or a salt solution of water or other electrically conductive liquid as a solvent for biologically active materials. When such a sample is placed in the probe coil of an NMR spectrometer, electrical losses in the conductive material lowers the Q of the receiving circuit and thereby reduces the sensitivity of the spectrometer. These electrical losses can be greatly reduced by breaking up the current paths within the sample. This can be achieved by a special sample cell (16) that compartmentalizes (17) the sample with electrical insulating material reducing the electrical current paths.
