摘要:
A solid solution particle of oxides contains a solid solution of oxides in which one oxide is dissolved into the other oxide, and in which the degree of dissolution of one oxide into the other oxide is not less 50%, and in which an average diameter of crystallite is not more than 100 nm. The solid solution particle of oxides has small average diameter of a crystallite and large specific surface area, and it improves capacities such as an oxygen storage ability due to high degree of dissolution. A catalyst for purifying exhaust gases has excellent purifying performance by employing the solid solution comprising ceria and zirconia which has large OSC and high oxygen adsorption and discharge speed.

An internal combustion engine in which a three-way catalyst (12) for purification of the exhaust gas is arranged in the exhaust passage, wherein the relationship between the magnitude of the stress causing deterioration of the three-way catalyst (12), for example the catalytic bed temperature, and the rate of deterioration of the performance of the catalyst is found. A durability test is performed by raising the catalytic bed temperature higher than that of the vehicle under market driving. The length of the durability test at this time is determined from the relationship between the catalytic bed temperature and the rate of deterioration of the performance of the catalyst so as to give the same degree of deterioration of the performance of the catalyst as with market driving. The length of the durability test required for giving the same degree of deterioration of the performance of the catalyst is much shorter than the market driving time.

An NOx storage member including at least one member selected from the group consisting of alkali metals, alkaline-earth metals and rare-earth elements, and at least one noble metal selected from the group consisting of Pt, Pd and Rh are loaded on a support including a porous oxide including TiO2 at least and ZrO2 on which Rh is loaded in advance. H2, which is generated by Rh/ZrO2, inhibits the sulfur poisoning, and the support, which includes TiO2 at least, secures the initial NOx purifying capability, thereby further inhibiting the sulfur poisoning. Accordingly, it is possible to inhibit the NOx storage member from the sulfur poisoning, and to maintain a high NOx conversion even after a durability test.

To enable power saving control by putting storage areas of the same attribute together in a specific RAID group in a storage apparatus that includes storage areas of different access patterns.The storage apparatus manages attributes of the RAID groups, which form a pool area, and attributes of the respective storage areas, based on an access log for each of the storage areas allocated to virtual volumes. The apparatus enables a power saving operation for each RAID group by putting the storage areas of each attribute together in a specific RAID group.

A data transfer device that confirms completion of writing into a memory on transferring data to the memory via a bus through which a response indicating completion of data writing in the memory is not sent back includes an inter-memory data transfer control unit performing data transfer between the memories. When the inter-memory data transfer control unit detects switching of a write destination memory from a first memory to a second memory, in order to confirm that writing into the first memory is completed, the inter-memory data transfer control unit performs confirmation of write completion as to the first memory by a procedure different from writing into the memory. When a data transfer with a designated transfer length is completed, in order to confirm that writing is completed as to the write destination memory at the end of the data transfer, the inter-memory data transfer control unit performs confirmation of write completion as to the write destination memory at the end of the transfer by the procedure different from writing into the memory. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of write completion.

A microchip 1 in which a resinous film can be inhibited from sagging into a channel. The microchip 1 comprises: a resinous substrate 2 having a channel groove formed therein; and a resinous film bonded to a surface of the substrate on which the channel groove has been formed. A micro-channel 3 including channels 3A and channels 3B is formed by the channel groove and the resinous film 10. The total length of the channels 3B, which is parallel to the X direction for the resinous substrate 2, is larger than the total length of the channels 3A, which is parallel to the Y direction for the resinous substrate 2. The resinous substrate 2 has been bonded to the resinous film so that the sides parallel to the channels 3B are parallel to the TD direction of the resinous film and that the sides parallel to the channels 3A are parallel to the MD direction of the resinous film.

A microchip has a resin substrate, which is provided with a first surface whereupon a channel groove is formed and a second surface on the opposite side to the first surface, and the microchip also has a resin film bonded on the first surface. A projection area is larger than the area of the first surface of the resin substrate when the resin substrate is viewed from a direction orthogonally intersecting with the first surface. Thus, warpage of the microchip can be suppressed at the time of thermally bonding the resin substrate and the resin film by a roller.
