摘要:
A powder density measuring device where a pair of purge gas-introducing paths is provided in a direction transverse to a material-measuring path in which pneumatically transported powder is introduced, and a pair of light transmission windows is provided so that the material-measuring path is viewable through the pair of the purge gas-introducing paths. A light projector is provided at one of the light transmission windows and a light receiver is provided at the other window so as to be opposed to each other. Powder density calculating/controlling means is provided, and, when a light beam radiated from the light projector is radiated to inside the material- measuring path, the means calculates powder density based on the amount of light received by the light receiver.

摘要:
Tablets containing a drug affected in contact with a lubricating agent, wherein the tablets contain no lubricating agent in it, the inner structure of the tablets comprises a compressed mixture of the drug with a filler, and a lubricating agent is located on the tablet surface. A process for producing tablets which involves the step of mixing a drug affected in contact with a lubricating agent with a filler to give a mixture; the step of mixing a lubricating agent powder and dispersing with air-pulsating wave under positive pressure; the step of spraying the lubricating agent powder, which has been dispersed by the above air-pulsating wave under positive pressure, onto the bottom face of the upper pestle, the top face of the lower pestle and the side face of the mortar of a tabletting machine so as to coat the bottom face of the upper pestle, the top face of the lower pestle and the side face of the mortar with the powder; and the step of compression-molding the above mixture by using the pestles and mortar coated at each surface with the lubricating agent.
