    摘要： A process for preparing an optically active 4-mercapto-2-pyrrolidone derivative of the formula [I]: ##STR1## wherein R.sup.1 is a hydrogen atom or a protecting group and R.sup.2 is a hydrogen atom or a protecting group, which comprises subjecting racemic 4-amino-3-mercaptobutyric acid or a salt thereof to optical resolution by using 1-(trichlorophenyl)ethanesulfonic acid, followed by subjecting the product to cyclization reaction after protecting the functional groups thereof, if necessary, and further optionally removing the protecting groups therefrom. The present process is industrially advantageous than conventional processes for preparing optically active 4-mercapto-2-pyrrolidone derivatives which are useful as an intermediate for various medicines such as carbapenem antibacterial agents.

    摘要： A synchronous pattern detection section checks coincidence between a predetermined reference synchronous pattern and a bit pattern included in a data stream. Each time a bit pattern which coincides with the reference synchronous pattern is detected, the synchronous pattern detection section extracts a frame length of a data frame corresponding to the bit pattern which is detected, and stores the extracted frame length in a storage section. Each time a bit pattern which coincides with the reference synchronous pattern is detected in the synchronous pattern detection section, a synchronization determination section determines whether or not the bit pattern detected by the synchronous pattern detection section is a correct synchronous pattern, based on a plurality of frame lengths stored in the storage section and a bit length of a data stream which is obtained after detection of the bit pattern. With this structure, a synchronous pattern included in the data stream can be detected with higher precision.
