    摘要: In a vector network analyzer with a transmitting and, a receiving side, each including a downward mixing super heterodyne receiver, a high voltage power supply for providing an accelerating voltage is arranged in series with a second power supply with a controllable lower output voltage so that unavoidable voltage variations in the acceleration voltage can be controlled. The second power supply is connected to the output of a phase and frequency discriminator by way of an amplifier and a low-pass filter. The discriminator has two inputs, one receiving the downwardly mixed transmitting side signal and the other the signal provided by a reference oscillator having a constant frequency. As millimeter wave oscillator a backward wave oscillator is used whose frequency drifting by temperature changes or by aging is compensated for by a control signal for the second power supply, which control signal is derived from the phase and frequency discriminator.

    摘要: A transcutaneous access port to a user has a coupling member destined to be anchored in a bone of the user. A first valve system is removably connectable to the coupling member and a second valve system is removably connected to the first valve system. An internal conduit is connected at its proximal end to the access port and at its distal end to a vascular structure of the user. An external conduit is connected to the access port and to an extracorporeal device. A traversing cavity is formed in the bone at an implantation site of the user, passing the internal conduit. The internal conduit is routed through the traversing cavity to connect its distal end to the vascular structure of the user. The coupling member is anchored to the bone at the implantation site. The proximal end of the internal conduit is connected to the access port.
