Abstract: A gold sputtering target has a gold purity of 99.999% or more. In such a gold sputtering target, an average value of Vickers hardness is 20 or more and less than 40, an average crystal grain size is 15 ?m or more and 200 ?m or less, and a {110} plane of gold is preferentially oriented to a surface to be sputtered of the gold sputtering target.

Abstract: A silver brazing material containing silver, copper, zinc, manganese, nickel, and tin as indispensable constituent elements. The silver brazing material includes 35 mass % or more and 45 mass % or less silver, 18 mass % or more and 28 mass % or less zinc, 2 mass % or more and 6 mass % or less manganese, 1.5 mass % or more and 6 mass % or less nickel, and 0.5 mass % or more and 5 mass % or less tin, with the balance being copper impurities. Within these compositional ranges, a predetermined relation is set between the manganese content and the nickel content, whereby the silver brazing material can be provided with excellent characteristics also in terms of processability or wettability. In the silver brazing material of the present invention, the silver content is reduced, and also melting point reduction and the narrowing of the temperature difference between solidus temperature and liquidus temperature are attempted.

Abstract: An area-isolation type solid-state image pickup device is such that an image pickup area is formed on an element formation surface of a semiconductor chip in a way to correspond to an optical image configuration of a subject, the semiconductor chip serving as an image pickup element, and an element drive circuit area and signal processing circuit area formed on a section other than the image pickup area. By doing so it is possible to fully utilize elements on an element formation surface of a semiconductor chip without ruining the element and hence to improve an efficiency with which a semiconductor device is manufactured.

Abstract: An oil pan for an internal combustion engine having an engine lubrication system. The oil pan comprises a shallow bottom section and a sump section. A guide plate is secured at an inner surface to which a crankshaft splashes lubrication oil carried into the shallow bottom section. The guide plate having an inclined and a guide parts extends generally along the axis of the crankshaft and extends generally parallel with a horizontal plane. The inclined part which gradually becomes high in level in the direction toward the sump is continuously connected to the inclined part to be formed in a generally arcuate shape. Therefore, the splashed oil at the inner surface cannot over the guide plate, and the oil is positively returned into the sump section by the guide plate. Accordingly, lubrication in this engine is smoothly carried out without causing a lack of the oil in the sump section.
