    摘要： A technology to automatically control the biasing of an optical duobinary transmitter using a single-drive LN-MZ modulator is provided. A low-frequency signal is amplitude modulated onto a voltage signal input into a Mach-Zehnder optical modulator 22. The optical output from the optical modulator 22 is detected by an optical detection subsystem 30. In a bias control subsystem 40, the low-frequency signal component amplitude modulated onto the electrical signal is detected from the optical output, and a DC bias voltage applied to the optical modulator is controlled such that the low-frequency signal component is either minimized or maximized.

    摘要： A blood collection needle which includes a needle for puncturing a patient's skin; a needle for puncturing a rubber plug which seals a blood collection tube; a hub for securing respective proximal portions of the two needles; a resilient cap fitted to the hub; and a valve member disposed in the internal passage of the hub which allows only blood flow from the needle used to puncture a patient's skin to the needle used to puncture the rubber plug which seals the blood collection tube. The valve member includes a bowl portion disposed so that the opening is faced toward the needle for puncturing the rubber plug and a guiding portion provided on a bottom surface of the bowl portion for causing the valve member to move to a predetermined position which closes the internal passage.
