    摘要: The present invention relates to a polarized xenon gas manufacturing supply device that is provided with a polarization cell 6 that produces a polarized xenon gas by polarizing a mixture of xenon gas and a diluent gas that consists primarily of a high-boiling-point gas that has a boiling point higher than that of the xenon gas, and a condenser (9) that cools the mixed gas discharged from the polarization cell (6) and condenses and separates the high-boiling-point gas by using the difference in boiling points between the xenon gas and the high-boiling-point gas, wherein the supply device is constructed so as to re-vaporize the condensed liquid of the high-boiling-point gas produced by the condenser (9) and introduce it to the polarization cell (6). This polarized xenon gas manufacturing supply device makes it possible to continuously manufacture and supply highly polarized and highly concentrated xenon gas.

    摘要: An electric power conversion apparatus includes first and second electric power conversion devices and a housing. The first and second electric power conversion devices are arranged to overlap each other in an overlap direction. The housing receives both the first and second electric power conversion devices therein. The housing has a partition wall that extends between the first and second electric power conversion devices to partition the housing into first and second parts in which the first and second electric power conversion devices are respectively received. The partition wall has a coolant passage formed therein, thereby allowing a coolant to flow through the coolant passage.

    摘要: The present invention provides a receiving optical subassembly (ROSA) with a co-axial shape and a stem for mounting semiconductor devices thereon that improves the high frequency performance of the ROSA. The ROSA mounts a photodiode (PD) and a pre-amplifier on a stem and the stem has a hollow the PD and the pre-amplifier are mounted therein. Since the hollow has a depth substantially equal to a thickness of the pre-amplifier, the bonding wire from the pre-amplifier to the surface of the stem may become shortest to reduce the parasitic inductance of the bonding wire and to enhance the high frequency performance of the ROSA.

    摘要: An exhaust emission control system of an internal combustion engine desorbs SOx by reversing a flow of an exhaust gas through an NOx storage-reduction catalyst, of which a structure is simplified as follows. A first exhaust pipe connected to an engine is connected to a first port of an emission switching valve having four ports. A second exhaust pipe 10, through which the exhaust gas is discharged into the atmospheric air, is connected to a second port, a third exhaust pipe connected to an inlet of a catalytic converter is connected to a third port. A fourth exhaust pipe connected to an outlet of the catalytic converter 30 is connected to a fourth port. When the emission switching valve is set in a forward flow position, the first exhaust pipe is connected to the third exhaust pipe, and the second exhaust pipe is connected to the fourth exhaust pipe, whereby the exhaust gas flows toward the outlet from the inlet within the catalytic converter. When the emission switching valve is set in a backward flow position, the first exhaust pipe is connected to the fourth exhaust pipe, and the second exhaust pipe is connected to the third exhaust pipe, whereby the exhaust gas flows toward the inlet from the outlet within the catalytic converter.
