摘要： The present invention is envisaged to provide an apparatus and a process for synthesizing lactide, according to which the water content in the produced lactide can be reduced. In operation of the system, lactic acid oligomer discharge valve 10 is closed, allowing transfer of lactic acid to its polycondensing apparatus 2, and concentration and polycondensation of lactic acid are advanced by heating and evacuation, with the produced water being evaporated. Lactic acid, lactic acid oligomer and lactide are removed from the produced gaseous body by condenser 11 and refluxed to the polycondensing apparatus, and then water content in the gaseous body is measured by pressure gauge 12. After confirming that the water content is below a specified value, lactic acid oligomer discharge valve 10 is opened to allow transfer of the lactic acid oligomer, said oligomer being depolymerized to produce gaseous lactide, which is condensed and recovered.

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： In search that uses searchable code, the search query and the secure index is collated in round-robins fashion, registering the required secure index and a characteristic quantity of deposited data in a database server to realize the searchable code. The server uses the characteristic quantity to perform clustering on the secure index. For search, collation is first performed only for representative data of a cluster. For a hit, the collation priority is raised for all the data included in the cluster. When there is no hit, the priority is lowered. After calculating the priority, collation is performed sequentially for all the data on the basis of the priority.
