摘要： A manufacturing method of a coil component includes: providing an assembly including a wound-wire part formed by winding, around a core, a conductive wire coated with a coating; and a lead part pulled out outwardly from the wound-wire; removing a portion of the coating from the conductive wire at a location outwardly extending away from the wound-wire part, wherein an entire coating over an entire circumference of the conductive wire at the portion of the coating is removed; providing a terminal electrode with a connecting part; forming a joining part at an end of the coating-removed lead conductive wire to electrically connect the terminal electrode to the lead part via the joining part by irradiating a laser from the connecting part toward the coating-removed lead conductive wire while restricting an irradiation range of the laser within a range where the coated lead conductive wire is not included.

摘要： In various aspects, methods of making perovskite manganese oxide particles are provided as well as perovskite manganese oxide particles made therefrom. The perovskite manganese oxide particles exhibit a strong magnetocaloric effect, making them well suited for applications in power generation and magnetic refrigeration, especially at or near room temperature. The methods can include forming an aqueous mixture of (i) a low-molecular-weight polymeric polyalcohol gel precursor, (ii) a stoichiometric amount of metal salts or hydrates thereof, wherein the metal salts or hydrates thereof comprise at least a Manganese (Mn), and (iii) a polybasic carboxylic acid; polymerizing the aqueous mixture to form a gel containing perovskite manganese oxide nanoparticles entrapped therein; and calcining the gel to remove at least a portion of organic material in the gel and form the perovskite manganese oxide particles. Method and systems are also provided for power generation and magnetic refrigeration using the perovskite manganese oxide particles.
