摘要:
In an optical transmission system using an RZ code, in order to improve the quality of the modulated transmission signal, an RZ optical modulator includes an RZ carver that outputs a optical pulse train of the RZ code, a polarization adjustment device which improves and outputs a polarization extinction ratio of optical pulse train outputted from the RZ carver and an optical modulator which modulates and outputs the optical pulse train outputted from a polarization adjustment device.
摘要:
A specimen rack can be used for specimen containers irrespective of kinds thereof and irrespective of whether or not the specimen containers are rotated. An adapter is used for an automatic analyzer and a specimen pre-processing device and is adapted for a specimen rack capable of holding specimen containers. The adapter is provided with a specimen rack mounting section inserted and fixed to an adapter insertion section of a specimen rack body, a specimen container positioning section for holding the specimen containers, and a sleeve.
