摘要： This invention provides apparatus for and a method of interferometrically inspecting a surface of an object. The invention is particularly well suited for inspecting semiconductor devices in the sub-micron range. A two beam interference microscope (102) obtains an image of an object (100) which is mounted on a piezo controlled sample table (104) and illuminated using a broadband light source. A CCD camera (100) obtains an image and the image is processed by using information derived from the interference fringes. The advantage is that large step heights can be measured and that a priori knowledge of the surface is not required. The invention can be adapted so that it can be used to simultaneously inspect and analyse an object, the latter being achieved by utilising data derived from a characteristic phase and/or spectral variation occurring in reflected light. This data can be manipulated mathematically e.g. by a Fourier Transform.

摘要： Periodontitis and susceptibility thereto is tested by measuring the change in morphology of a sample of polymorphonuclear leukocytes (PMNs) from the patient at a predetermined time after incubation thereof with supernatant from a virulent strain of Porphyromonas gingivalis and comparing the result with that from a sample of PMNs from a healthy patient. Since loss of polarisation corresponds to a loss of actin which is bound by phalloidin, the change can be measured by observing a decrease in fluorescence of fluorescently labelled phalloidin in the sample. In serious cases there is a complete loss of fluorescence.

摘要： A method and apparatus for continuously extruding a product, and forming it into a bend by applying a force (20) to it at a point of application downstream of where its surface becomes solid. The force has a transverse component relative to the die axis (18), and performs work upon the extruded material (5), extra to the work that has already been performed to extrude it. Non-contact means of applying the force are described, and various ram-type contacting means (33) are illustrated. Alternative means of operation are described in which the point of application of the force to the extrudate during bending varies relative both to the extrudate and to the die (4), relative to the extrudate only, and relative to the die only. Means to alter the direction of bending are described, and to diminish the necessary bending force by creating a fluctuating melt pressure within the die.

摘要： A magnetic material of at least two component parts arranged to have respective structures which mutually are not homogenous, the structure of one part cooperating with the structure of the other to assist (fig. 3) the magnetostrictive behaviour of the material. The cooperation can be the structure of one part altering the atomic spacing of the other part (fig. 1, fig. 2). The alteration can be an increase from the usual atomic spacing. There can be contiguous component parts and the cooperation can be a pseudo free surface on at least one said part or a reduced restriction of the local moment otherwise achieved by the contiguous component parts (fig. 5). A component can be at least partly an alloy and the alloy can have ratio other than the usual one for said alloy. One of the components can be non-magnetic.

摘要： A PET radiation detector includes a pair of amplifying gaps (3, 21) to enhance the electron yield from a TAME gas, BaF2 gamma detector, together with a gate electrode (17) to inhibit passage of charge to the detector electrodes and reverse passage of ions to the crystal. A further reverse-biased gap may be positioned adjacent the crystal to prevent charge build-up thereon. Shield electrodes (23, 25) prevent gate switching signals causing spurious responses in the detector circuit.

摘要： A poultry harvester comprises a pick-up head feeding birds from the front end of the harvester on to a conveyor belt (18). The pick-up head comprises a three-rotor array with the poultry-handling elements (28) on each rotor (12, 13, 14) abutting and/or intermeshing with the elements of the other two rotors of the array. Stationary sidewalls flank both sides of the conveyor belt (18) and barrier loops (351) extend away from these sidewalls to interdigitate with the guide elements of rotors (12, 13) and embrace the cores of these rotors. This prevents birds from being pulled between the sidewalls and the adjacent rotors. A similar arrangement may also be used at the rear end of the harvester.

摘要： A bulk ionically conductive polymer gel is prepared by dissolving a salt such as lithium trifluoromethanesulphonate (which would provide lithium ion conductors) in an organic compound such as N-formylpiperidine. The organic compound dissolves the salt at 20 DEG C but is not a solvent at 20 DEG C (though it is at 215 DEG C) for polyethylene terephthalate. The last-named is a crystallisable polymer which is added in a minor amount at a high temperature to the other components and provides the required mechanical rigidity for the product at lower temperatures.

摘要： Solid polymer electrolytes for electrochromic devices are produced by dissolving lithium perchlorate and polymethylmethacrylate in propylene carbonate, all dried to below 10 ppm water, and screen printing or casting a film of the resulting solution followed by removal of solvent to leave a final polymer concentration of about 40 % by weight based on the combined weight of polymer and solvent. Screen printability is conferred by a resin modifier such as MODAFLOW .
