Abstract: In a dynamometer, an internally cooled disc is utilized in a braking system which can apply a large amount of torque for an extended period of time. A hollowed braking disc (24) comprising individual cooling cells (50) is employed. Cooling liquid is injected into the center of the braking disc and, by centrifugal force, is forced into the cooling cells (50) via a flow tube ring (44). The cooling liquid vaporizes in the cooling cells thus absorbing the heat generated. The vapor escapes the disc via vent holes (68). A unique torque measurement system is also utilized with its braking system. A resultant force, formed by the sum of individual forces upon braking pistons (27,28) within the braking system, is measured utilizing a strain gauged load cell. The strain gauged load cell is strategically positioned to measure a resultant displacement of the braking caliper due to the applied torque.

Abstract: A method of writing and reading coded data writes and reads the coded data which are coded by an orthogonal transform coding so that an original image can be restored progressively or sequentially, where the original image is divided into blocks of an arbitrary number of pixels and the coded data are obtained by coding quantization coefficients which are obtained when gradation levels of the pixels within each block are subjected to a two-dimensional discrete cosine transform. The method comprises the steps of extracting the quantization coefficients for each restoration stage, subjecting the extracted quantization coefficients to a variable length coding, writing the variable length coded quantization coefficients into storage means as the coded data, reading the coded data from the storage means, restoring a code length of the coded data based on the read coded data, extracting coded data corresponding to the restored code length from the read coded data, and outputting the extracted coded data as coded data required in each restoration stage.

Abstract: 2.1 Microlenses are used for mould fitting when coupling monomode fibres to optical semiconductor components. The aim now is to achieve this mode fitting with the elimination of optical lenses. 
<??>2.2 For this purpose, a first integrated optical waveguide to which the semiconductor component is to be coupled is embedded in a second, larger waveguide to which the monomode fibre is to be coupled. The first waveguide narrows down in the form of a taper in the second waveguide and terminates at a distance from an end face of the second waveguide. The optical waveguide coupled into the first waveguide expands owing to the fact that this waveguide becomes thinner, up to the point where the wave guidance is taken over by the second waveguide.

Abstract: Steel sheet coated with a nontoxic, relatively insoluble, inorganic, corrosion resistant coating. A silicate coating is formed on a steel sheet by rinsing the sheet for at least 30 seconds in an alkaline aqueous solution containing 0.005 M silicate, 0.005 M metal salt and having a temperature of at least 25 DEG C. The sheet is dried to form an adherent silicate coating having a thickness of at least 2 nm prior to being treated with an aqueous solution containing 0.5-5 vol.-% silane. If the sheet is painted, the silane film forms an adherent bond between the paint and the silicate coating. A silane treated silicate coating minimizes red rusting on terne coated steel by sealing pin holes. A silane treated silicate coating also provides good corrosion protection and paint adherence on cold-rolled or galvanized steel.
