Abstract: A refrigeration cycle device for a vehicle includes a refrigerant circuit, in which a zeotropic refrigerant mixture is circulated, including a utilization heat exchanger including a first heat exchange portion and a second heat exchange portion disposed in series with the first heat exchange portion in a direction in which the zeotropic refrigerant mixture flows in the refrigerant circuit. The first heat exchange portion is disposed on an upstream side of the second heat exchange portion in a direction in which the zeotropic refrigerant mixture flows when the utilization heat exchanger functions as an evaporator of the zeotropic refrigerant mixture.

Abstract: An air conditioner, which is a heat pump apparatus, includes a refrigerant circuit, a compressor, and a composition adjustment mechanism. The refrigerant circuit circulates a non-azeotropic mixture refrigerant including a first refrigerant and a second refrigerant having a boiling point higher than the first refrigerant. The compressor compresses the non-azeotropic mixture refrigerant. The first refrigerant is a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds. The composition adjustment mechanism is provided in the refrigerant circuit. The composition adjustment mechanism prevents an increase in the rate of the first refrigerant included in the non-azeotropic mixture refrigerant discharged from the compressor.

Abstract: A method of manufacturing ferromagnetic particle exothermic elements for performing a deposition treatment for causing a treating aqueous solution containing fluorine and iron to contact nucleus particles, to deposit iron hydroxide and form layers around the nucleus particles, and an after-treatment for heating the iron hydroxide layers to change them into ferromagnetic layers, thereby producing ferromagnetic particle exothermic elements with outside of the nucleus particles covered by the ferromagnetic layers, wherein, in time of the deposition treatment, a reaction initiator that reacts with hydrogen fluoride is added to said treating aqueous solution.

Abstract: Exothermic elements (30) for hyperthermic treatment having, as a main component thereof, ferromagnetic layers (20) coated outside nucleus particles (10). The ferromagnetic layers (20) comprise an oxide having a magnetic domain structure mainly formed of at least one of a single domain and a pseudo-single domain. These exothermic elements for hyperthermic treatment may be manufactured by heating after depositing iron hydroxide on the nucleus particles (10) by a liquid phase process.
