  • Patent number: 8227463
    Abstract: [Problems] The object is to improve the absorbability of a heterocyclic compound including s-triazine and a pyrimidine derivative in vitro. [Means for Solving Problems] Disclosed is, for example, an amorphous body of a heterocyclic compound as represented by the general formula (I) [wherein each of R's and others is as defined in the description] including s-triazine and a pyrimidine derivative, or a hydrate, a solvate or a pharmaceutically acceptable salt of the heterocyclic compound. Also disclosed is a process for producing the amorphous body. Further disclosed are: a solid dispersion comprising the amorphous body; and a medicinal preparation comprising the solid dispersion.

  • Patent number: 4873793
    Abstract: A numerically controlled machine tool for machining a non-circular workpiece according to profile data. The servomotor drive unit of the machine tool includes a frequency voltage converter which outputs a velocity compensation signal proportional to the frequency of position command pulses in the servomotor drive units. A position error signal is modulated by the velocity compensation signal. The numerical controller of the machine tool can measure the position error and phase error, and can compensate for these errors. The numerical controller operates according to ideal profile data and measures the actual position change of a tool slide corresponding to the angle position change of a main spindle. Then, the numerical controller calculates the position error and phase error depending on the actual position change and ideal profile data, and produces execution profile data which are compensated for position error.
