    Abstract: 本發明提供一種維持能量密度並且降低內部電阻之電極。於活性物質層12中形成凹凸，藉此活性物質層12至集電層11之厚度於凹凸中變化。因此，於如凹凸之凹部33般至集電層11之距離較小之部分，電性之內部電阻降低。又，活性物質層12之凹凸係藉由對活性物質層12施加力而形成。因此，包含於活性物質層12中之活性物質粒子之總量不會變化。藉此，於在活性物質層12中形成凹凸之情況下，於凹凸之形成之前後，活性物質層12之能量密度不產生變化。

    Abstract: In a half thrust bearing for a crankshaft, a slide surface includes at least two oil grooves extending in a radial direction, pad surfaces located on both circumferential sides of each oil groove, a first inclined surface formed on a forward side of the oil groove in a rotation direction of the crankshaft, and a second inclined surface formed on a backward side of the oil groove in the rotation direction. Each of the first and second inclined surfaces has a circumferential length which varies along the radial direction and includes a ridge portion at a radial position where the circumferential length is minimum. The axial thickness of each of the first and second inclined surfaces is maximum at the ridge portion in the radial direction and become smaller from the ridge portion toward a radially inner end and toward a radially outer end.

    Abstract: A bearing device includes a piston arranged in a cylinder of a rotor, and a half bearing mounted on the piston to support a roller. The piston includes a recessed holding surface, and holding side surfaces on both axial sides thereof. Each holding side surface includes a ridge portion having an arc-shaped or elliptic-arc-shaped profile protruding toward a radially inner side of the piston. The half bearing includes a partially cylindrical portion, and protruding portions protruding from axial end faces thereof. Each protruding portion has a protruding portion end face which includes a central recessed surface, and two support recessed surfaces located on both circumferential sides thereof, that have an arc shape or an elliptic arc shape to correspond to the profile of the ridge portion, so that only the two support recessed surfaces are in contact with the ridge portion.

    Abstract: Provided is a half bearing constituting a sliding bearing that is unlikely to cause damage during an operation of an internal combustion engine. The half bearing includes at least one protrusion, and the protrusion projects outward in a radial direction from an outer circumferential surface. A recessed portion that is recessed inward in the radial direction from the outer circumferential surface is formed over the entire inner-circumferential length between the protrusion and a circumferential-direction end surface of the half bearing. Two radial-direction grooves are formed in the circumferential-direction end surface of the half bearing relative to the protrusion, and each of the radial-direction grooves is adjacent to each of recessed portion side surfaces. The radial-direction grooves extend in the radial direction along the recessed portion side surfaces and are separated from the recessed portion at a midpoint of the extension. An inner circumferential surface-side end portion in an extending direction of the radial-direction grooves is located between a recessed portion bottom surface and an inner circumferential surface of the half bearing. A groove width and a groove depth of the radial-direction grooves decrease from the position separated from the recessed portion toward the inner circumferential surface-side end portion and reach zero at the inner circumferential surface-side end portion.
