Abstract: A biosensor that can perform analysis based on a sample noninvasively collected from a human body is provided. The biosensor comprises an identification substance (38) that binds to a substance to be detected (40), and an electrode (16) charged with a charge of the identification substance (38), comprises an inhibitor (39) that inhibits a substance not to be detected (42) from attaching to at least one of the identification substance (38) and the electrode (16), and detects a change in a charge density of the electrode (16) caused by binding of the substance to be detected (40) to the identification substance (38).

Abstract: A slide surface of a thrust bearing includes a planar portion, a taper portion, and a pocket portion. The pocket portion includes a bottom surface, a first side surface, and a second side surface. The first side surface is formed on the side of the taper portion. The second side surface is formed on a side opposed to the first side surface. A depth from the plane of the planar portion to the thinnest portion of the taper portion is between 10 ?m and 80 ?m. A first angle that is an angle between a virtual surface obtained by extending the bottom surface and the second side surface is between 90° and 120°. And a second angle that is an angle between a virtual surface obtained by extending the first side surface and the tapered surface is between 60° and 120°.

Abstract: A bearing device includes a thrust bearing. The thrust bearing has a bearing surface in a half-split ring shape, and a plurality of oil grooves formed to cross the bearing surface from an inner circumferential side to an outer circumferential side. Further, the thrust bearing includes a first thrust bearing that is disposed on a side surface facing a side of a transmission, and a second thrust bearing that is disposed on a side surface facing an opposite side to the transmission. In the first thrust bearing, a bearing surface between the plurality of oil grooves is configured by including a taper surface formed so that a wall thickness becomes thicker toward a rotation direction of the crankshaft. Further, in the second thrust bearing, a bearing surface between the plurality of oil grooves is configured by a plane in which a wall thickness is constant.
