  • Publication number: 20230036035
    Abstract: An information processing apparatus comprises a first heat generation circuit, a second heat generation circuit, a blocking assembly, and a processor. The blocking assembly performs a first operation of blocking air flowing from the first heat generation circuit toward the second heat generation circuit or a second operation of passing the air, and the processor is configure to instruct the blocking assembly to perform the first operation in a case where a temperature of the air is higher than a predetermined value, and instruct the blocking assembly to perform the second operation in a case where the temperature of the air is lower than the predetermined value.

  • Patent number: 11559788
    Abstract: The problem to be solved by the present invention is to provide an oxygen storage and release material comprising a ceria-zirconia-based complex oxide improved in ability to remove HC and NOx and a three-way catalyst able to reduce an amount of NOx emission. Further, to solve this problem, an oxygen storage and release material comprising a ceria-zirconia-based complex oxide containing Gd2O3 in 0.1 mol % or more and less than 20 mol % and having an ion conductivity of 2×10?5 S/cm or more at 400° C. is provided. Further, in addition to the above, an oxygen storage and release material having a molar ratio of cerium and zirconium of 0.2 or more and 0.6 or less by cerium/(cerium+zirconium) and an speed of oxygen storage and release “?t50” of 20.0 seconds or more or amount of oxygen storage and release of 300 ?mol-O2/g or more etc. was obtained.
