Abstract: A driving force transmission device includes drive rollers, roller support portions, and a roller arrangement portion. The drive rollers transmit a driving force to a main wheel. The roller support portions rotatably support the drive rollers. The roller arrangement portion includes a base, an outer frame, and an inner frame. The base expands radially outward with respect to a rotation axis. The outer frame extends in a circumferential direction around the rotation axis and protrudes from the base in an axial direction along the rotation axis. The inner frame is radially inside the outer frame and protrudes from the base in the axial direction. The roller support portions are fitted between the inner circumferential surface of the outer frame and the outer circumferential surface of the inner frame.

Abstract: A lithium ion secondary battery according to an embodiment of this disclosure includes: a positive electrode mixture layer provided on a main plane of a positive electrode current collector; a negative electrode mixture layer provided on a main plane of a negative electrode current collector; and an insulator covering a region of a part of a surface of a gradually-decreasing portion included in the positive electrode mixture layer. The portion has thickness gradually decreasing toward a terminal of the positive electrode mixture layer; the surface of the portion has a tangent line in contact with the surface in at least two contact points, and has a depressed part between any adjacent two contact points on the tangent line; and an end of the insulator is positioned between the contact points closest to and farthest from the terminal of the positive electrode mixture layer along the tangent line.

Abstract: A lithium ion secondary battery includes: a positive electrode mixture layer provided on a main plane of a positive electrode current collector; and an insulator covering a part of a surface of a gradually-decreasing portion included in the positive electrode mixture layer. A first region is smaller than a second region on a cross-section of the lithium ion secondary battery that is orthogonal to the main plane, the first region being defined by a perpendicular line to the main plane passing a contact point between the surface of the gradually-decreasing portion and an end of the insulator, the main plane, and the surface of the gradually-decreasing portion, and the second region being defined by an orthogonal line orthogonal to the perpendicular line and in contact with an upper surface of the positive electrode mixture layer on a plane including the cross-section, the perpendicular line, and the surface of the gradually-decreasing portion.

Abstract: A human monoclonal antibody against a protein comprising the same or substantially the same amino acid sequence as the amino acid sequence represented by SEQ ID NO: 1 or SEQ ID NO: 3, its partial peptide, or a salt thereof, is useful as an agent for preventing/treating cancer, etc., an apoptosis inducer of cancer cells, a growth inhibitor of cancer cells, a cytotoxic agent against cancer cells through a host defense mechanism mediated by the Fc region of an antibody, and so on.

Abstract: The present invention provides an antibody capable of specifically recognizing the same amino acid sequence as an antigenic determinant of mouse monoclonal antibody MAB-ME-16F4.3 (FERM BP-10329), and an antibody of capable of specifically recognizing the same amino acid sequence as an antigenic determinant of mouse monoclonal antibody MAB-ME-12C9.2 (FERM BP-10328), and methods of risk prediction of bone fracture and/or diagnosis of osteoporosis by detecting a MEPE-derived molecule in a biological sample using the above-mentioned two kinds of antibodies.

Abstract: The Battery pack of the present invention consists of the upper half 10 and lower half 60 which can be joined to each other. The upper half 10 comprises an elastic rubber gasket 20 which is integrally molded into the upper half 10. The elastic rubber gasket 20 has a sealing section 21 providing for water-proof characteristics and passage sections 22 providing for gas release. The sealing section 21 comes in contact with the sealing surface 62 of the lower half 60, thus providing for water-proof joining of the upper half 10 and the lower half 60. The purpose of the gas release sections 22 is to allow venting of gas generated during the recharging of the batteries.

Abstract: An electrical pin comprises a metal pin having plated metal members at peripheral end surfaces thereof and head members including solder secured to the end surfaces of the metal pin and the plated metal members.
