  • Patent number: 9255014
    Abstract: A method for producing a thermoelectric conversion material composed of a metal A having an alkali metal or alkaline earth metal, a transition metal M, and oxygen O, and represented by AxMyOz, where x, y, and z are valences of the respective elements, includes the steps of: using a massive metal oxide as the thermoelectric conversion material and a salt in a solid, liquid or gaseous state; causing a diffusion reaction between the oxide and the salt; and forming the thermoelectric conversion material having aligned crystal orientation. A production apparatus includes a reactor into which the oxide and the salt are introduced, and a heating means for heating the oxide and the salt within the reactor to promote the diffusion reaction. Thereby, the thermoelectric conversion material having efficiency is produced more simply and at lower cost than a production of the single crystal.

  • Patent number: 8959001
    Abstract: A test pattern is sequentially selected from an original test pattern sequence constituted by a plurality of test patterns including a don't care bit. Power consumption in each of regions obtained by substantially equally dividing a layout region of a semiconductor integrated circuit in a case where a don't care value is specified in the selected test pattern and this selected test pattern is applied to the semiconductor integrated circuit is estimated. A searching is conducted for a don't care value of the selected test pattern which minimizes a variation in power consumption among the regions by repeatedly changing the don't care value and repeatedly estimating power consumption in the regions. A new test pattern sequence constituted by a plurality of test patterns including no don't care bit is generated by defining the don't care value obtained by the searching as a don't care value of the selected test pattern.
