Abstract: The process comprises repeatedly depositing inside a quartz reaction tube a soot-like core forming glass (26) at different temperatures, by which a distribution of a doping concentration in the radial direction of the core can be set as desired. 
     A modification to the process comprises forming two constricted portions (28) at opposite ends of a quartz reaction tube (4), charging a solution of a compound of a rare earth element as a solution into the section of the tube between the constricted portions (28) for doping. By this method, the doping concentration becomes uniform along the length of an optical fiber preform (30) with defects being rarely produced and without any complicated operation.

Abstract: A system for signalling the presence of selected ion species in a gaseous sample of an ion mobility sensor (10), having a unidirectional field provided between first and second electrodes (16, 18) positioned a selected distance apart. An ionization source (35) generates ions in the sensor and a trigger controller (42) allows ions to enter the region (12) between the first and second electrodes at a time t₁. The ions then arrive at the second electrode at a time t₂. A transimpedance amplifier (38) converts the ion charges to voltage signals. The presence of selected ion species is determined by circuitry that is activated by the trigger controller at t₂. The species are preferably analyzed by directing the amplifier output to an analog to digital converter (56) and then to a digital signal processor (58). The ions may alternatively be analyzed by generating a logic pulse representing a selected ion species when the amplifier output exceeds a preset value. An alarm signal is output when the logic pulse is coincident at an AND gate (46) with a logic pulse representing the species' travel time from the first electrode to the second electrode.

Abstract: A brighter white opacified paint, which contains a conventional film-forming polymer together with a conventional optical brightener and particles anatase titanium dioxide and/or zinc sulphide as the white opacifier. Unlike the rutile form of titanium dioxide, the anatase form or zinc sulphide enables the optical brightener to function usefully in the presence of the white opacifier especially when the amount of optical brightener present is not more than 10 micromoles/g of the non-volatiles content of the paint. Preferably the particles are encapsulated in polymer or attached to a discontinuous polymer barrier comprising particles of organic polymer in order to space them apart and improve opacity. A small amount of fluorescence is also obtainable from chloride-produced rutile.

Abstract: A video signal processing apparatus for use in a two-panel liquid crystal projector includes a matrix circuit (54) for receiving a luminance signal and colour signals output from a luminance/chroma processor (53) and generating colour signals in a different way from that of an existing matrix circuit. A matrix circuit (54) generates a new luminance signal by adding the minimum value of the colour difference signals to the luminance signal. The minimum value is subtracted from the respective colour difference signals to generate new colour signals. Another matrix circuit (54) generates colour signals and a luminance signal which are applied to a liquid crystal panel (57, 58) based on the minimum value of the colour signals which are obtained by the existing matrix circuit (54) instead of using the colour difference signals. The colour signals and luminance signal which are obtained by the respective matrix circuits (54) are used for light modulation for a colour liquid crystal panel (58) and white/black liquid crystal panel (57). Then, amplitude of the newly obtained luminance signal is controlled by an amplifier (66, 75) having an amplification factor based on a difference between light utilization efficiencies of the luminance signal and the colour signals which are displayed on a screen. Thus, an unnatural image phenomenon is removed and resolution and brightness can be improved. Further, disharmonization between the luminance signal component and the colour signal component can be prevented in view of the optical and signal processing conditions.
