A bubble separator used in a fluid circuit for an automobile and that separates bubbles in a refrigerant may include a swirl flow formation part extending in a substantially horizontal direction, and including an internal space having a columnar shape. The bubble separator may also include a flow inlet disposed at one end of the swirl flow formation part, and being open so as to cause the refrigerant to flow in the flow inlet in a tangential direction of an inner peripheral surface of the swirl flow formation part and so as to form a swirl flow on the inner peripheral surface. The bubble separator may also include a flow outlet disposed at another end of the swirl flow formation part, and being open so as to cause the refrigerant to flow out of the flow outlet in a tangential direction from the inner peripheral surface. The bubble separator may further include a gas discharge port to discharge gas separated from the refrigerant in the swirl flow formation part outside of the swirl flow formation part, and at least one liquid drop nozzle provided on a wall surface of the swirl flow formation part.

A bus arbitration system uses different arbitration rules at different times, by periodically changing the priority order of the bus masters; by masking further bus requests from a particular bus master for a certain interval each time that bus master is granted the use of the bus; by masking requests from bus masters other than a central processing unit for certain intervals while the central processing unit is processing an interrupt; by raising the priority of a particular bus master if a bus request from that bus master remains unacknowledged for a certain interval; or by ignoring bus requests from the central processing unit while another bus master is performing a certain process.

A memory system includes a plurality of output buffers each of which outputs one of a plurality of one-bit signals forming data. The output buffers are put into a plurality of buffer groups. The memory system further includes a controller for feeding timing signals to the corresponding buffer groups via delay circuits having mutually different time constants, respectively. The timing signals include certain timing which causes the output buffers to output the corresponding one-bit signals. Since the foregoing certain timing is delayed depending on the time constants of the delay circuits, although the output buffers in the same buffer group output the corresponding one-bit signals simultaneously, the output buffers in the different buffer groups output the corresponding one-bit signals with mutually different timing.

Data output system

A data transfer controller transfers data in blocks having a restricted set of permitted sizes. Before transferring each block, the data transfer controller performs a segmented comparison on the current data address, at which the block starts, and a stopping address, at which the entire data transfer will end, and determines the block size from the result of the segmented comparison. In the segmented comparison, the data transfer controller compares a first part of the data address with a first part of the stopping address, then compares a second part of the data address with a second part of the stopping address. The comparison of second parts is made in different ways, depending on the result of the comparison of first parts.

The present invention relates to a slurry thickening tank comprising a tank body disposed below the surface of a slurry within a slurry tank, a slurry inlet provided in the upper part of the tank body, a thickened slurry outlet provided in the lower part of the tank body, and supernatant liquid withdrawal means provided in the upper part of the tank body, whereby the slurry introduced into the tank body through the slurry inlet is thickened by sedimentation in the tank body and the resulting thickened slurry is discharged from the tank body through the slurry outlet, wherein the surface of the structural member of the tank body extending from the slurry inlet to the thickened slurry outlet has an angle of inclination greater than the angle of repose for the thickened slurry, and to an absorption tower for use in flue gas desulfurization systems which is equipped with such a slurry thickening tank. This slurry thickening tank can maintain satisfactory operating conditions for a long period of time without developing any trouble such as a blockage of the thickened slurry outlet.

Slurry thickening tank and absorption tower for use in wet flue gas

This invention is related to a slurry filtration device and the wet lime-gypsum flue-gas desulfurization system comprising a slurry filtration device for the separation (concentration) of gypsum. The slurry filtration device comprises tank that has a slurry supply pipe at its upper part and a filtrate-drain hole at its bottom, a layer of filter sand lying on its bottom, a slurry accumulator arranged on the layer of filter sand, and a vibrator set in said slurry accumulator for vibrating the slurry. The present invention not only improves the solid-liquid separability remarkably but also saves cost and space.

Slurry filtration device and flue-gas desulfurization system

A wet type flue gas desulfurization apparatus in which desulfurization of flue gas is carried out through gas/liquid phase contact of flue gas with an absorbent slurry. More particularly, disclosed in a combined absorption tower comprising an absorbent slurry liquid tank, a thickening tank serving for concentration by settling of a reaction product slurry formed through the reaction of the absorbent and SO.sub.2 present in flue gas, an absorption section situated above said liquid tank for the gas/liquid contact of flue gas and the absorbent slurry as well as for carrying out the desulfurization reaction, and a stack section situated above said absorption section serving for the dispersion of the treated flue gas into the atmosphere, wherein the absorption section is provided with nozzles for upward spraying of the absorbent slurry, and flue gas introduced at the bottom of said absorption section and absorbent slurry sprayed through the nozzles are subjected to gas/liquid contact, and a unreacted portion of the absorbent slurry and a reaction product slurry descend into said liquid tank, and the reaction product slurry from said liquid a tank is introduced into said thickening tank.
