摘要:
An engine valve, formed of a titanium alloy, enables improvement of reliability and productivity while improving creep resistance and fatigue strength at a high temperature. The engine valve, including a stem section and a bevel section provided at one end of the stem section, is integrally formed of the titanium alloy. A portion of the valve, extending from the bevel section to a medial portion of the valve stem, is formed mainly of a needle-like crystallographic texture. Another portion of the valve, extending from the medial section to the other end of the stem section, is formed of a material having a substantially equiaxed crystallographic texture. A boundary between the needle-like texture and the equiaxed texture is provided in a range of sliding movement of the valve relative to a valve guide that slidably guides the stem section within the cylinder head.

摘要:
The present invention relates to an information processing device, an information processing method, and a program for easily acquiring information. A television receiver accesses an application server and acquires an application list therefrom. When an application is selected from the application list, the television receiver again accesses the application server and acquires the selected application therefrom. While executing a process based on the acquired application, the television receiver accesses a content server as needed and acquires content data therefrom. The acquired application and content data are deleted from a storage unit when an end of the process based on the application is designated. The present invention applies to television receivers which acquire data via a network.

Next, an opening reaching at least a surface of the insulating substrate is formed in the source electrode, the GaN layer and the n-type AlGaN layer. Then, a nickel (Ni) layer is formed in the opening. Thereafter, by conducting dry etching from the back side while making the nickel (Ni) layer serve as an etching stopper, a via hole reaching the nickel (Ni) layer is formed in the insulating substrate. Then, a via wiring is formed extending from an inside the via hole to the back surface of the insulating substrate.
