Provided are a porous sintered compact suitable for a filter, a power feeder in a polymer electrolyte membrane type water electrolyzer, a current collector in a solid polymer fuel cell and in addition a liquid dispersion plate, especially an ink dispersion plate for an ink jet printer ink and the like. A titanium powder sintered compact made of a plate-like porous compact is obtained by sintering spherical powder made of titanium or a titanium alloy produced by means of a gas atomization method. A void ratio in the range of from 35 to 55% is realized by filling without applying a pressure and sintering without applying a pressure.

An engine exhaust treatment device is capable of combusting PM accumulated in a DPF or activating an exhaust purification catalyst even immediately after engine startup or at the time of light load operation. A combustible gas supply passage (8) communicates with an exhaust passage (4) on an upstream of a combustion catalyst (5). An air supply unit (9) and an ignition unit (10) are provided in this supply passage and interlocked with a control unit (11). Where a temperature of the exhaust is lower than a predetermined temperature, the control unit supplies air (12) to a combustible gas by the air supply unit (9) and causes ignition of the combustible gas by the ignition unit (10), so as to cause flame combustion of the combustible gas. The temperature of the exhaust (6) in the exhaust passage (4) is increased by heat of this flame combustion.
摘要:
The present invention provides a method for washing a separation membrane module after filtering raw water containing particles having a hardness higher than that of a separation membrane. Thus, after completion of filtration, water at the primary side in a separation membrane module is drained to outside the system, backwash waste water in the separation membrane module is then drained while carrying out backwash, and any of the steps of: (a) filling the primary side in the separation membrane module with water and carrying out air scrubbing; and (b) carrying out air scrubbing while feeding water to the primary side in the separation membrane module is then carried out, followed by draining water at the primary side in the separation membrane module to outside the system.
