  • Patent number: 10276475
    Abstract: A thermal conductive stress relaxation structure is interposed between a high-temperature substance and a low-temperature substance to conduct heat in a heat-transfer direction from the high-temperature substance to the low-temperature substance. The structure includes an assembly configured such that a thermal conductive material gathers in a non-bonded state having stress relaxation effect. Such an assembly is a rolled-up body configured such that a carbon-based sheet material and a metal-based sheet material are alternately rolled up, for example. This structure has one or more interfaces at which adjacent parts can slide, thereby dividing a deformable region to relax the thermal stress. It has a low rigidity and can thus deform to release the thermal stress. The structure can suppress the thermal stresses and the shape changes that would be generated in the high-temperature substance and the low-temperature substance, and each physical body located there between.

  • Patent number: 10214093
    Abstract: A transmission unit is able to switch between a non-neutral state where power of an engine is transmitted via a path K1 and a neutral state where power of the engine is not transmitted via the path K1. A clutch is able to switch between an engaged state where power is transmitted from the engine to a first MG and a released state where transmission of power from the engine to the first MG is interrupted. When the transmission unit is controlled to the non-neutral state and, at the same time, the clutch is set to the released state, a vehicle is operable in series-parallel mode. When power is transmitted via the path K2 by directly coupling the engine to the first MG by the clutch and the path K1 is interrupted by controlling the transmission unit to the neutral state, the vehicle is operable in series mode.
