Abstract: A shot peening method is disclosed. One method includes performing a first shot peening for applying residual stress to a surface of an object formed of a metal material at a first depth, and performing a second shot peening for applying residual stress to the surface of the object at a second depth deeper than the first depth after the first shot peening. The first shot peening is performed before the object is used at a high temperature and the second shot peening is performed after the object is used at the high temperature, and after a cracking caused by stress due to thermal expansion and contraction of crystal grains occurs in the object. The cracking being deeper than the first depth and shallower than the second depth.

Abstract: Provided is a thermoacoustic refrigerator including an air column pipe, a prime mover, a load, and a heat accumulation tank. An exhaust gas supplied to and discharged from the heat accumulation tank is supplied, as a heat source, to the prime mover disposed inside the air column pipe, so as to cause self-oscillation of a working gas filled in the air column pipe so that sound waves are generated. With the sound waves, the load disposed inside the air column pipe converts sound wave energy into heat energy, so as to output cold heat.

Abstract: A separation device that separates a mixture of magnetic bodies that are granular and non-magnetic bodies that is granular into the magnetic bodies and the non-magnetic bodies. The separation device includes a magnetic force separating mechanism, a wind force generation portion, a first wind force separating portion, and a second wind force separating portion. The magnetic force separating mechanism separates the mixture into first separated objects and second separated objects by attracting the magnetic bodies from the mixture of magnetic force. The first separated objects mainly contain the magnetic and non-magnetic bodies. The second separated objects mainly contain the non-magnetic bodies and magnetic bodies. The wind force generation portion generates wind force. The first wind force separates the first separated objects into the magnetic and non-magnetic bodies of wind force. The second wind force separates the second separated objects into the non-magnetic bodies and magnetic bodies of wind force.
