  • Patent number: 8520867
    Abstract: Provided is a high-accuracy embedded audiphone. A transducer (34) made of a giant magnetostrictive element is provided in an intracorporeal unit (3) that is embedded in a skull (5). An audible sound modulation transmission signal (S1), which is amplitude-modulated by a sound collection signal generated in an extracorporeal unit (2), is transmitted from an extracorporeal transmitter coil (31) to an intracorporeal receiver coil (32) provided in the intracorporeal unit (3) with the help of a transmission magnetic flux (33). Moreover, because of an induced electromotive force of the intracorporeal receiver coil (32), the transducer (34) expands and contracts. Therefore, it is possible to highly accurately conduct an audible sound signal through bone with no power source or demodulation circuit provided in the intracorporeal unit (3).

    Abstract: Column which includes a first column with an upper layer of H2SO4 silica gel and a lower layer AgNO3 silica gel and a second column packed with alumina, connected detachably to a lower end of the first column. An oily liquid containing polychlorinated biphenyls, is added to the upper layer and heated. An aliphatic hydrocarbon solvent is supplied to the upper layer, whereby polychlorinated biphenyls captured by the first column are dissolved in the aliphatic hydrocarbon and then flow to the second column. The polychlorinated biphenyls are captured by the alumina which is located near the inlet of the second column, which is then detached from the first column. A hydrophobic solvent is passed through the second column in a direction opposite to the direction in which the aliphatic hydrocarbon was passed, providing an extract containing the polychlorinated biphenyls dissolved in a small amount of the hydrophobic solvent.
