  • Patent number: 10497852
    Abstract: A thermoelectric conversion material includes a matrix phase configured from a semiconductor. A first grain-boundary phase and a second grain-boundary phase are provided at a grain boundary of the matrix phase. The first grain-boundary phase is configured from a material which does not form a compound with the matrix phase by a eutectic reaction, a eutectoid reaction, a peritectic reaction, a peritectoid reaction, an eccentric reaction, or a segregation reaction. The second grain-boundary phase is configured from a material having resistance which is lower than that of the matrix phase or the first grain-boundary phase. A ratio of a volume of the second grain-boundary phase to a volume of the first grain-boundary phase is smaller than 1.

  • Patent number: 10448711
    Abstract: A first connector assembly may be connectable to a second connector assembly using a sliding attachment process, in which a front portion of the first connector assembly is inserted into an end of a slot in the second connector assembly and slides laterally along the slot until electrical contacts on the two connector assemblies are aligned. Electrical contacts of the first connector assembly may be biased proud to make contact with recessed electrical contacts in the second connector assembly. A retraction mechanism may be provided to retract the electrical contacts of the first connector assembly during lateral sliding. An interlock mechanism may be provided to prevent unwanted operation of the retraction mechanism.
