摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a soft magnetic member, which can favorably reduce iron loss. SOLUTION: In an annealing process of a soft magnetic member, the soft magnetic member is retained at an annealing temperature of 550°C to 850°C only for an annealing time period of 0.5 to 20 minutes, and the total time period for which the soft magnetic member is retained at a temperature of 400°C or higher is set to 3 to 100 minutes. This method can substantially reduce the time period for which the soft magnetic member is retained at a high temperature in comparison with conventional methods, thereby substantially reducing heat deterioration of organic constituents of the soft magnetic member and preventing increase in eddy-current loss. Further, it is found that distortion stress of the soft magnetic member is reduced to a required level in spite of short-time retention at a high temperature, thereby allowing hysteresis loss to be reduced favorably.

摘要翻译：要解决的问题：提供可以有利地减少铁损的软磁性部件的制造方法。解决方案：在软磁性部件的退火处理中，软磁体仅在退火时间为0.5〜20分钟的条件下保持在退火温度为550℃〜850℃，总时间将软磁性部件保持在400℃以上的温度下，设定为3〜100分钟。与常规方法相比，该方法可以显着降低软磁体在高温下保持的时间，从而大大降低了软磁体的有机组分的热劣化，并防止了涡流损耗的增加。此外，发现尽管在高温下保持短时间，但是软磁性构件的变形应力降低到所需水平，从而可以有利地降低磁滞损耗。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To adhere an adsorbent to an adsorption core (fin) without lowering an adsorption capacity of the adsorbent while reducing number of manufacturing steps. SOLUTION: An adsorbent 34 is adhered to an adsorption core (fin 50) via a thermosetting powder adhesive or thermoplastic powder adhesive. Thus, since the adsorbent 34 is adhered to the fin 50 in the state that the adhesive is dispersed on a surface of the adsorbent 34, the state that the adhesive covers much the surface of the adhesive 34 can be prevented, and a substantial decrease in an adsorption capacity of the adsorbent 34 can be prevented. Since a drying step, a cleaning step and the like can be abolished, the number of manufacturing step can be decreased, and hence the manufacturing cost of an adsorption module can be reduced.
