摘要： A foil bearing unit includes: a first foil holder formed of a single component; a radial bearing foil mounted to an inner peripheral surface of the first foil holder; a thrust bearing foil mounted to an end surface of the first foil holder; and an inner member including: a shaft portion; and a flange portion projecting radially outward from the shaft portion. The inner member is supported in a radial direction by a fluid pressure that is generated in a radial bearing gap between a bearing surface of the radial bearing foil and an outer peripheral surface of the shaft portion, and the inner member is further supported in a thrust direction by a fluid pressure that is generated in a thrust bearing gap between a bearing surface of the thrust bearing foil and one end surface of the flange portion.

摘要： The present invention aims to shorten a drying time for time for drying a coiled electrode. To this end, a drying device for drying the coiled electrode wound on a winding core includes a heating unit for heating the coiled electrode from a winding core side. Since this enables heat to be transferred from a core part toward a surface of the coiled electrode, tiny spaces can be generated between layers of an electrode and moisture can be evaporated from these spaces. Thus, moisture of the core part side, which has been difficult to evaporate, can be reliably evaporated and a drying time for the coiled electrode can be shortened.
摘要翻译：本发明旨在缩短用于干燥线圈电极的时间的干燥时间。为此，用于干燥缠绕在卷芯上的卷绕电极的干燥装置包括：加热单元，用于从绕组芯侧加热线圈电极。由于这样能够使热量从芯部朝向线圈电极的表面转移，所以在电极层之间可能产生微小的空间，并且可以从这些空间蒸发湿气。因此，能够可靠地蒸发难以蒸发的芯部侧的水分，能够缩短线圈电极的干燥时间。
