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.

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.

A hydrogen fuel feeding system of a fuel cell system that has: a switching device for switching a reactor, that can carry out a reforming process and a regeneration process, between alternate statuses of a first status of feeding a reactant to the reactor while exhausting a fuel gas and a second status of feeding a gas for regeneration to the reactor while exhausting a regeneration exhaust gas; and a control apparatus for switching the switching device so that residual reforming gas, which is still remaining in the reactor before switching, is combusted in an exhaust air processor and not exhausted as the residual reforming gas without treatment when switching from the first status to the second status.

A fuel reforming apparatus includes a reforming catalyst, a filtering member, a raw material supply flow passage and a processed gas flow passage. The filtering member has a plurality of cells. A reforming catalyst is carried on a surface of a partition on the side of the processed gas flow passage. If raw gas including hydrocarbon fuel is supplied to the fuel reforming apparatus and filtered by the filtering member, soot included in the raw gas is trapped by gaps in the partition, and the hydrocarbon fuel is reformed into reformed gas including hydrogen and carbon monoxide on the reforming catalyst. By increasing the amount of air supplied from a blower at intervals of time, the soot trapped by the partition is removed by combustion.

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.

A hydrogen generation device includes a catalyst; a sulfur-trap member; a soot-trap member; a pair of reformers; and a control portion. In each reformer, a reforming reaction is carried out to generate hydrogen-containing gas using gasoline and cathode off-gas on the catalyst, and an exothermic reaction is carried out to heat the catalyst using anode off-gas and air. The control portion executes a control such that the reactant and the exothermic material are alternately supplied to each reformer, whereby the reforming reaction and the exothermic reaction are alternately carried out in each reformer. A fuel cell system includes the hydrogen generation device.

摘要:
A hydrogen extraction unit has reformed gas flow channel plates, hydrogen separation plates, and purge gas flow channel plates, which are designed as thin metal plate members. The hydrogen extraction unit is constructed by laminating these thin plate members and then bonding them together by diffusion bonding. Each of reformed gas flow channel holes formed in the reformed gas flow channel plates constitutes a flow channel for reformed gas together with a correspondingly adjacent one of the hydrogen separation plates. Each of purge gas flow channel holes formed in the purge gas flow channel plates constitutes, together with a correspondingly adjacent one of the hydrogen separation plates, a flow channel for purge gas with which hydrogen extracted from reformed gas is mixed.
摘要:
An NOx absorbent is arranged in an engine exhaust passage absorbs NOx when the air-fuel ratio of inflowing exhaust gas is lean and discharges absorbed NOx or SOx when the oxygen concentration of inflowing exhaust gas decreases. When the air-fuel ratio of the exhaust gas flowing into the NOx absorbent is rich, previously absorbed NOx or SOx is discharged from the NOx absorbent. When NOx or SOx is to be discharged from the NOx absorbent, oxygen is left in the exhaust gas flowing into the NOx absorbent and the oxygen concentration of this exhaust gas is maintained within a predetermined range.

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.
