A lower link () is provided with an oil hole () in a crank pin bearing portion () in order to supply a jet of oil to a connecting portion between an upper pin () and an upper link (). Oil hole () is composed of a first oil hole () linearly extending from the inner peripheral surface of crank pin bearing portion () outwardly in the radial direction, and a second oil hole () linearly extending from the outer surface of lower link () so as to intersect a distal end portion of first oil hole (). An inclination angle (θ) of first oil hole () with a divided surface () set as a reference becomes relatively small, and hence the position of an oil inlet () involving a problem of stress concentration becomes closer to divided surface () exhibiting a relatively low stress. Consequently, the stress concentration at oil inlet () is alleviated.

Lower link of internal combustion engine

A lower link () is formed of two components by being divided at a dividing surface () including the central axis of a crank pin bearing portion (), the two components including a lower link upper () with an upper pin bearing portion () and a lower link lower () with a control pin bearing portion (). The dividing surface () includes a first dividing surface () located more on the upper link side than the crank pin bearing portion () and a second dividing surface () located more on the control link side than the crank pin bearing portion (). In the lower link (), the first dividing surface () has a surface roughness larger than a surface roughness of the second dividing surface ().

Multi-link piston crank mechanism for internal combustion engine

An internal combustion engine has a lower link rotatably mounted to a crankpin of a crankshaft, an upper link having a first upper link end rotatably connected to a piston pin of a piston and a second upper link end rotatably connected to a first lower link end side of the lower link through a first connecting pin, and a control link having a first control link end supported on a cylinder block and a second control link end rotatably connected to a second lower link end side of the lower link through a second connecting pin. When viewed in an axial direction of the crankshaft, the second connecting pin is arranged to swing along a lateral direction substantially perpendicular to a center axis of a cylinder of the internal combustion engine.

A lower link () is formed such that outer circumferential sides of both end portions of a crankpin through-hole () are stiffer than a center portion of the crankpin through-hole (), i.e. a bifurcation portion of a bifurcated shape thereof. The both end portions of the crankpin through-hole () are formed such that inner circumferential surfaces () of the both end portions are curved at a predetermined curvature in an axial direction of a crankshaft with no load input on the lower link (). Moreover, the center portion of the crankpin through-hole () is formed such that an inner circumferential surface () thereof is located inward of the inner circumferential surfaces () of the both end portions and is straight in the axial direction of the crankshaft with no load input on the lower link ().

Multi-link piston-crank mechanism for internal combustion engine

A multi-link piston crank mechanism includes a crank pin bearing portion including a crank pin bearing central portion that is disposed at a center thereof in an axial direction of a crank shaft. The crank pin bearing central portion at a portion positioned on the first end side of the lower link is thicker in a radial direction of the crank pin than a portion positioned on the second end side of the lower link. The second control link end portion is thicker along a radial direction of the second through hole than the second upper link end portion along a radial direction of the first through hole.

When the compression ratio of a variable compression ratio internal combustion engine () is set at a low compression ratio, a lubricating oil ejected from a lower link oil passage () is reflected by an upper link () at the piston top dead center, and supplied to a cylinder inside wall surface on the side on which a control link () is located in a view as viewed in the axial direction of the crank shaft. When the compression ratio of the variable compression ratio internal combustion engine () is set at a high compression ratio, the lubricating oil ejected from lower link oil passage () is reflected by upper link () at the piston top dead center, and supplied to the back side of the piston crown.

An electrostatic charge image developing carrier includes magnetic particles and a resin coating layer which covers the magnetic particles, wherein a sulfate ion concentration of the resin coating layer is 0.05% by weight or less with respect to a total weight of the resin coating layer, and when a total value of a molar amount of sulfate ions contained and a molar amount of sulfo groups contained per 1 g of the resin coating layer is A mol and a molar amount of sodium ions contained per 1 g of the resin coating layer is B mol, a relationship of 0.1&#x3c;B/A&#x3c;1.2 is satisfied.

An opening on one end side of a pin-boss oil passage opens to the inner circumferential surface of a pin boss part of an upper link, while an opening on the other end side thereof opens to the outer circumferential surface of the pin boss part of the upper link. A lower-link oil passage has a one-end-side opening structured to open to a pin-boss-facing surface of the lower link facing the outer circumferential surface of the pin boss part of the upper link and its other-end-side opening structured to open to a crankpin bearing surface. The lower-link oil passage is configured to point, at a prescribed crankangle, to a specified end edge of end edges of the other-end-side opening of the pin-boss oil passage, the specified end edge facing one end side of the upper link.

A lubricating mechanism of a multilink, piston-crank mechanism for an internal combustion engine is provided. At a predetermined crank angle at which the crank pin oil passage and the lower link oil passage are communicative, viewed in the direction of the crankshaft, along a straight line connecting the center of rotation of the crank shaft and the end of the lower link oil passage at the side opposed to the pin boss opposing surface, the pin boss portion is disposed as the lubricating object. On the axial side of the pin boss portion, a recess portion is provided.

This invention provides a majority circuit, connecting a plurality of processing units. The majority circuit can detect a single error or multiple errors, and sets the majority output signal to an ineffective level when multiple errors are detected. The majority circuit includes comparators, each comparing two outputs of three processing units, and the error detector recognizes the error status and outputs the single error signal and the multiple error signal accordingly. The majority circuit also includes a selector, which selects the output of a normal processing unit, when the normal processing unit can be specified based on the comparison result. The selector changes the output to a predetermined level, when the normal processing unit cannot be specified.
