Abstract: A vehicular image display system includes: an image writing control part that writes first image data generated by a first application operating under a first operating system sequentially in image storage parts by switching of the image storage parts; an image reading control part that reads the first image data from the image storage parts sequentially by switching of the image storage parts; a display data generation part that combines the first image data and second image data generated by a second application operating under a control of a second operating system with higher reliability than the first operating system; an error detection part that checks the first image data; and a switching control part that suspends the switching of the image storage parts by the image writing control part and by the image reading control part, when an error is detected.

Abstract: In order to dynamically perform operation verification for each function of a program that is being run, a vehicle-mounted information processing section (22) performs operation verification of a function provided on the basis of the execution of a distribution program (141) by a computation section (23). Verification data (151) to be provided by the function is stored in a vehicle-mounted storage device (30). Operation verification for a function provided on the basis of the execution of the distribution program (141) by the computation section (23) is carried out on the basis of comparison of display data (Pd) that is generated on the basis of the execution of the distribution program (141) with verification data (151) that is stored in the vehicle-mounted storage device (30).

Abstract: A slide bearing including a metal backing; an Al-based intermediate layer; and an Al-based bearing alloy layer is disclosed. The Al-based bearing alloy layer includes one or more types of intermetallic compounds containing Al and two or more other types of elements, the Al-based bearing alloy layer including 8 or more grains of intermetallic compounds per ?m2 having a grain diameter less than 0.5 ?m. When the elements constituting the intermetallic compound are represented as X1, X2, . . . , Xn (n is a positive integer), a relative abundance of the elements satisfy X1?X2? . . . ?Xn. An abundance ratio X1/X2 of element X1 to element X2 ranges from 1 to 10. The Al-based bearing alloy layer has a Vickers hardness ranging from 50 to 80.

Abstract: Disclosed is a sliding bearing having excellent fatigue resistance property under a high specific load. The sliding bearing has a back metal layer 2, an Al-base alloy intermediate layer, and an Al-base bearing alloy layer which contains grains of an intermetallic compound consisting of Al and at least two other elements. The grains include relatively smaller size grains each having a grain size of less than 0.5 ?m.

Abstract: A multilayer aluminum-base alloy bearing formed by bonding a bearing alloy layer made of an aluminum-base alloy to a steel back metal through an intermediate layer made of an aluminum-base alloy, the intermediate layer being composed of two layers, that is, a lower layer and an upper layer, the lower layer in contact with the steel back metal being lower in hardness than the upper layer. Since the lower layer is soft, it is excellent in bonding property for the back metal, and since the upper layer is hard, it withstands a load exerted on the bearing alloy layer.

Abstract: Disclosed is a multi-layered Al-base bearing consisting of a steel back layer, an intermediate Al alloy layer and an Al-base bearing alloy layer which contains one or more elements selected from the group of Cu, Zn, Mg and Si, and which is bonded to the steel back layer via the intermediate Al alloy layer. The bearing is subjected to solution treatment at a temperature of not lower than 400° C. The intermediate Al alloy layer has a sub-layer being in direct contact with the steel back layer, and at least one sub-layer positioned closer than the former sub-layer to the Al-base bearing alloy layer. The former sub-layer consists of an Al alloy contains 2 to 8 mass % Si, and has a thickness proportion of 5 to 25% to the entire thickness of the intermediate Al alloy layer.

Abstract: An aluminum bearing-alloy containing 1.5 to 8 mass % of Si is provided, in which there can be observed Si grains on the sliding surface of the aluminum bearing-alloy. A fractional area of the observed Si grains having a grain size of less than 4 ?m is 20 to 60% of a total area of all the observed Si grains. Another fractional area of the observed Si grains having a grain size of from 4 to 20 ?m is not less than 40% of the total area of all the observed Si grains.
