A thermal storage type gas treating apparatus has a high sealing performance while achieving a simple apparatus construction. The thermal storage type gas treating apparatus includes a valve member rotatable to place successively a supply port for a gas to be treated and an exhaust port for a treated gas formed in the valve member, in an opposed and communicating relationship with supply and exhaust ports formed in a distributor, thereby successively passing gas to be treated and treated gas through a plurality of thermal storage chambers communicating at one end with a combustion chamber. The valve member is supported to be displaceable toward and away from the distributor. A valve biasing device is provided for pressing the valve body to the distributor, while being inoperative with respect to a gas chamber device.

A purging apparatus for a fuel cell system according to the present invention comprises a steam supply passand an air supply pass. A purging method for the fuel cell system according to the present invention comprises, at a time of causing a fuel reformer, a fuel cell bodyand a fuel supply lineto carry out the purging operation, first carrying out the purging operation by steam, and then carrying out the purging operation by air. According to such a structure, there can be provided the purging apparatus for the fuel cell system and the method therefor, which have an easy structure and an easy operation, and enables combustible gas and condensed water remaining in the system to be removed in a reliable manner.

Purging method of fuel cell system

In active driving of liquid crystal panels (R, G, and B) corresponding to R, G, and B color by X shift registers (R, G, and B) and Y shift registers (R, G, and B), alternating-current driving is performed such that signals to be written to the R color and B color liquid crystal panels are opposite in polarity to a signal to be written to the G color liquid crystal panel and also Vcom voltage of each of the liquid crystal panels is adjusted to thereby reduce flicker. The Vcom voltage supplied to the B color liquid crystal panel, for example, is finely adjusted to reduce flicker of a synthetic image of the liquid crystal panels.

A full automatic washing machine includes an outer tub, a rotatable tub rotatably mounted in the outer tub, an agitator rotatably mounted in the rotatable tub and an electric motor for driving the rotatable tub and the agitator. The volume of clothes accommodated in the rotatable tub is detected. A control circuit controls either a stored-water rinse mode in which the clothes are rinsed with water being stored in the rotatable tub or a rinse-with-dehydration mode in which the clothes are rinsed and dehydrated with the water supplied into the rotatable tub. The stored-water rinse mode is selected when the detected volume of clothes is large. The rinse-with-dehydration mode is selected when the detected volume is small.

A projector rear is simple in structure uses reflection type liquid crystal plates to project images on a screen. R light emitted by a light source is directed to a first liquid crystal plate via a first dichroic mirror. Light reflected from the first liquid crystal plate is reflected toward a projection axis by the first dichroic mirror. B light transmitted through the first dichroic mirror is reflected by a second dichroic mirror and impinges on a second liquid crystal plate. Light reflected by this second liquid crystal plate is again reflected toward the projection axis by the second dichroic mirror. G light is made to directly enter a third liquid crystal plate. G light reflected by the third liquid crystal plate travels along the projection axis. The angular positional relations among optical elements are so set that the angle of incidence to the normal to each dichroic mirror is close to the angle of reflection.

Projector system

A fuel cell power plant comprised of a fuel cell main unit to which a fuel is supplied, a containment vessel for housing the fuel cell main unit; a purge gas supply pipe for introducing a purge gas which excludes combustion elements in the containment vessel; and a combustion element removal apparatus which is provided with the purge gas supply pipe and which effectively removes combustion elements in the purge gas before the purge gas is introduced in the containment vessel. The fuel call power plant may include a fuel reformer having at least a reforming space, and may use a reformed fuel gas or a used fuel gas as the purge gas from which the combustion elements are removed. The fuel reformer may include a burner for a reforming reaction, and in this case, the power plant may use a burner exhaust gas as the purge gas from which the combustion elements are removed. The combustion elements mainly include oxygen and reactive carbon which are removed from the purge gas before being supplied to the containment vessel.
