    摘要： A foil bearing includes an outer member (11), and a plurality of foils (13) that are mounted to an inner circumferential surface (11a) of the outer member (11) and directly face the inner circumferential surface (11a) of the outer member (11) in a radial direction without interposition of another member (such as back foils). The foils (13) each include: holding portions (13a, 13b) that are formed at both circumferential ends and held while in contact with the outer member (11); and a body portion (13c) that is formed circumferentially between the holding portions (13a, 13b) and has a bearing surface (A). At least an end portion on one side in a circumferential direction of the body portion (13c) is raised radially inward with respect to the inner circumferential surface (11a) of the outer member (11).

    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： In a tapered roller bearing assembly, a crowning profile formed portion of the roller rolling surface is made up of a contact area crowned portion, which is held in contact with an inner ring raceway surface, and a non-contact area crowned portion which is held in non-contact with the inner ring raceway surface. The contact area crowned portion and the non-contact area crowned portion have their generatrices extending in an axial direction of a roller, which generatrices are represented by corresponding continuous lines represented by different functions and continued smoothly at a point of connection, and the curvature of the generatrix of the non-contact area crowned portion in the vicinity of the connection point is chosen to be smaller than the curvature of the generatrix of the contact area crowned portion.
