This invention relates to processes for producing an olefin-terminated polyester. In one of the processes which comprises reacting an olefin-terminated diester compound with a lactone in the presence of a polymerization catalyst with transesterification ability, the lactone is in a limited amount added to the reaction system. In another process which comprises reacting an olefin-terminated diester compound, a lactone compound, a cyclic acid anhydride and an epoxy compound in the presence of a polymerization catalyst with transesterification ability, the lactone, cyclic acid anhydride and epoxy compound are each in a limited amount added to the reaction system. In accordance with this invention, olefin-terminated polyesters having high terminal modification rates can be synthesized.

摘要:
A radar apparatus for detecting a distance to an object by receiving an electromagnetic wave reflected by the object is disclosed. The radar apparatus comprises a scan part and an electromagnetic wave emitter. The scan part includes a polarized light separation member configured to pass a preset first component of the electromagnetic wave and reflect a preset second component of the electromagnetic wave. The first and second components, respectively, are polarized lights having first and second polarization directions, which are perpendicular to each other. The scan part scans the second component of the electromagnetic wave in a predetermine scan angle range by rotating the polarized light separation member around a predetermined rotation axis. The electromagnetic wave emitter emits the electromagnetic wave toward the polarized light separation member of the scan part.
摘要:
Disclosed is a technology of discharging, from a drug cartridge, a drug instructed to discharge, while managing a plurality of drugs stored in a drug cartridge. The technology makes it possible to correctly discharge the drugs even when the dosing order of the drugs is changed. A medical agent dispenser has: a main body case (1); an annular drug cartridge (2) which is housed in the main body case (1) and has a plurality of holders (3) at equal intervals in the longitudinal direction; a discharge mechanism (7) which discharges the drugs from the holders (3); and an input interface (6) which receives operations of leading the drug to be discharged. Based on the number of operations the input interface (6) has received, gears (4a, 4b), i.e., rotating mechanisms which rotationally transfer the drug cartridge (2), are controlled.
