Abstract: A microwave heating method using a microwave, including: controlling a frequency of the microwave, to form a single-mode standing wave; disposing an object to be heated in a magnetic field region where a strength of a magnetic field formed by the single-mode standing wave is uniform and maximum; and heating the object to be heated by magnetic heat generation by magnetic loss caused by an action of the magnetic field of the magnetic field region, and/or induction heating by an induced current generated in the object to be heated due to the magnetic field of the magnetic field region.

Abstract: CO2 introduced into the ground reacts with water in the moisture present in the surroundings to convert to hydrocarbon, suppressing leakage of CO2 above ground. The method for producing hydrocarbon has an introduction step for introducing CO2 into a storage site in the ground where moisture and a catalytic metal are present, the pressure is 5 MPa or higher, and the temperature is 40° C. or higher, to bring the CO2 into a subcritical state or a supercritical state, and a synthesis step for reacting the water in the moisture with the subcritical or supercritical CO2 in the storage site to synthesize hydrocarbon. The storage site is preferably a site from 800 m to 1200 m below ground. The pressure of the storage site is preferably 8 MPa or higher.

Abstract: A Magnetic-field melting preform solder that melts by action of an AC magnetic field, wherein the preform solder includes a laminated structure made up of two or more layers, at least two layers constituting the laminated structure is made up of solder material, the at least two layers do not contain ferromagnetic material, each of the at least two layers includes a surface facing with each other, and the surfaces facing with each other are in contact with each other. A bonding method using the preform solder includes a providing the preform solder between an electrode on a substrate and an electrode of an electronic component, and bonding together the electrode on the substrate and the electrode of the electronic component by generating an AC magnetic field around the substrate and thereby melting the preform solder.
