    Abstract: A plurality of heat receiving ribs are projected inwardly from the inner wall surfaces of a crankcase of a splashing oil lubrication type internal combustion engine. The heat receiving ribs extend in the same direction of a crankshaft so as to easily absorb heat from splashed engine oil. As a result, the temperature in the crankcase is reduced, thereby the lubrication characteristic of the engine oil can be maintained in good condition.

    Abstract: A method of forming a compound semiconductor device. The method includes the steps of depositing a film that contains zinc oxide and silicon oxide to contain the zinc oxide by 70 wt % or more on compound semiconductor layer as a diffusion source, and diffusing zinc from the diffusion source into the compound semiconductor layer by annealing. Accordingly, there can be provided a compound semiconductor device manufacturing method containing the step of diffusing zinc into compound semiconductor layers, capable of deepening a Zn diffusion position from a ZnO/SiO2 film to such extent that COD endurance of laser end face window structures can be increased rather than the prior art.

    Abstract: A main bearing case has a bearing holder for holding a bearing so as to support a crankshaft, and a crankcase mounting section at which it is joined to a crankcase. Rib walls are provided so as to surround the bearing holder between the bearing holder and the crankcase mounting section. The rib walls are formed in a side of the crankcase, and in a neighborhood of each inner side face of the bearing holder and the crankcase mounting section. These rib walls receive a force exerted in a radial direction from the crankshaft. Thereby, an improvement of rigidity of the main bearing case can be achieved, and also the lubrication to a valve-operating system can be always ensured by preventing an oil surface from lowering even when an engine is located with inclination.

    Abstract: A hydrogen barrier layer is formed above a ferroelectric thin film in an integrated circuit. The hydrogen barrier layer is directly over a protected segment of the ferroelectric thin film, while a sacrificial segment of the ferroelectric thin film extends laterally beyond the edges of the hydrogen barrier layer. The sacrificial segment absorbs hydrogen so that it cannot diffuse laterally into the protected segment of the ferroelectric thin film. After it absorbs hydrogen, the sacrificial segment is etched away to allow electrical connection to circuit layers below it. The ferroelectric thin film preferably comprises a layered superlattice compound. Excess bismuth or niobium added to the standard precursor solution of a strontium bismuth tantalum niobate compound helps to reduce hydrogen degradation of the ferroelectric properties.

    Abstract: In an integrated circuit, a stack of thin film layers comprising respectively a bottom electrode, a thin film of metal oxide, a top electrode, a lower barrier-adhesion layer, a hydrogen barrier layer, and an upper barrier-adhesion layer are patterned to form a memory capacitor capped with a self-aligned hydrogen barrier layer. Preferably, the top and bottom electrodes comprise platinum, the metal oxide material comprises ferroelectric layered superlattice material, the upper and lower barrier-adhesion layers comprise titanium, and the hydrogen barrier layer comprises titanium nitride. The hydrogen barrier layer inhibits diffusion of hydrogen, thereby preventing hydrogen degradation of the metal oxides. Part of the upper barrier-adhesion layer is removed in order to increase the electrical conductivity in the layer. Preferably, the memory capacitor is a ferroelectric nonvolatile memory. Preferably, the layered superlattice material includes strontium bismuth tantalate or strontium bismuth tantalum niobate.
