Proposal of self-standing support method for vibration reduction of refrigerator compressors
Nihon Kikai Gakkai ronbunshu, 2018 In household refrigerators, the rotational speed of a reciprocating compressor can be appropriately adjusted according to the temperature inside of the refrigerator. The lower rotational speed reduces the power consumption of the compressor.

Heat pumping in nanomechanical systems [PDF]
, 2011 We propose using a phonon pumping mechanism to transfer heat from a cold to a hot body using a propagating modulation of the medium connecting the two bodies. This phonon pump can cool nanomechanical systems without the need for active feedback.
