Abstract: A method of manufacturing a tablet containing coated granules comprising compressing the coated granules containing biologically active substance and having a temperature exceeding a room temperature, whereby the tablet can be prevented from rupture of a part of a coating film of the granules at the time of tablet compression.

Abstract: The present invention provides a cast steel for ring-shaped components that has a low average coefficient of thermal expansion in a temperature range of 20° C. to 500° C. and high strength and good oxidation resistance at 500° C., which are required for ring-shaped components for use as blade rings and seal ring retainers of gas turbines, and that can hence be used for blade rings and seal ring retainers of gas turbines. Specifically, the present invention provides a high-strength and low-thermal expansion cast steel comprising, on a mass percentage basis, 0.1 to 0.8% of C, 0.1 to 1.0% of Si, 0.1 to 1.0% of Mn, 0.01 to 0.1% of S, greater than 40% and up to 50% of Ni, not greater than 4% (inclusive of 0%) of Co, greater than 1.5% and up to 4% of Cr, 0.01 to 0.1% of Al, and 0.001 to 0.1% of Mg, the remainder being substantially Fe.

Abstract: There is disclosed a water-soluble vitamin composition which containing about 90 to 99.8% by weight of a water-soluble vitamin, a polymer binder and at least one additive selected from the group consisting of monosaccharides, disaccharides, sugar alcohols, dextrin and organic acids, which can provide a tablet having high mechanical strength (hardness) with less compression problem and easy disintegration, upon compression. A process for producing the composition is also disclosed.
