摘要： A method for producing a polylactic acid includes the steps of (a) crystallizing polylactic acid pellets obtainable by direct polymerization of lactic acid or ring-opening polymerization of lactide; and (b) removing low-molecular components having a weight-average molecular weight of 1,000 or less in the resulting crystallized, solid polylactic acid pellets by gasifying the low-molecular components to obtain polylactic acids with substantially no low-molecular components. In this method, an apparatus for removing low-molecular components in polylactic acid pellets includes a crystallizing means for maintaining a temperature between equal to or higher than a glass transition temperature of polylactic acid pellets and equal to or lower than the melting point thereof, while fluidizing the polylactic acid pellets; and a reactor for allowing a heated inert gas and/or heated air to pass through the resulting crystallized, solid polylactic acid pellets obtained by the crystallizing means.

摘要： The polymerization reaction is conducted by heating a lactide, a cyclic imide compound (e.g. succinimide, etc.) and a polymerization catalyst (e.g. tin octylate, etc.) at 100-190.degree. C. with stirring under a nitrogen gas flow. It is preferred that an amount of the cyclic imide compound is from 1 to 35% by mole based on the lactide. Even if an amount of the polymerization catalyst is small, e.g. 0.00001-0.1 mole %, based on the lactide, polylactic acid can be efficiently prepared. It is possible to avoid remains of the catalyst in the polymer and coloring of the polymer.

摘要： In a 3-dimensional animation generating apparatus which uses a computer, the user generates a number of static images having parent-child relationships and which serve as key frames in the sequence from the start to the end of the animation, a number of animation frames specified by the user being automatically inserted between the key frames by means of interpolation. In this 3-dimensional animation generating apparatus, the times of each of the key frames as specified by the user are stored, the parent object coordinates and child object coordinates generated by the user are stored in a world coordinate system, along with parent-child relationship in each of the key frames. When the 3-dimensional animation generating apparatus generates interpolated frames, the parent-child relationship in neighboring key frames in the time sequence is interpolated to first generate the parent-child relationship existing in the interpolated frame, after which the parent object coordinates in the interpolated frame are calculated in the world coordinate system by interpolating the parent object coordinates in each of the neighboring key frames. The coordinates of a child object in an interpolated frame are determined from the parent-child relationship within the interpolated frame and the parent object coordinates in the interpolated frame. The animation is thus generated from the interpolated frame parent object coordinates, the interpolated frame child object coordinates, and the parent-child relationship.

摘要： In an interactive editing apparatus, a three-dimensional object to be edited is a set of polygonal surfaces which are arranged in a three-dimensional space and have the same number of sides. These polygonal surfaces are arranged on the three-dimensional space to display on a perspective view, the sides of the polygonal surfaces are linearly enveloped to express a polygonal three-dimensional object. When a user edits any one of vertex positions, data regarding the edited vertex and associated other vertex positions are updated. Further in the interactive editing apparatus, data regarding vertexes and faces of the object are managed using data cells, and shape data before the last editing are stored in the data cells together with present shape data, whereby an undo function is realized.
