Abstract: According to one embodiment, a display control apparatus includes a memory, an output module, and a setting module. The memory is configured to store first menu configuration information to compose a first menu screen and second menu configuration information to compose a second menu screen. The output module is configured to output first menu screen display information to display the first menu screen based on the first menu configuration information and content data in response to a selection operation of the first menu screen, and to output second menu screen display information to display the second menu screen based on the second menu configuration information and content data in response to a selection operation of the second menu screen. The setting module is configured to set one of the first menu screen and the second menu screen as a top menu displayed at a startup timing.

Abstract: According to one embodiment, an application operation control apparatus includes a manager, a creator, and a controller. The manager is configured to manage an application configured in XML and script. The creator is configured to create a dummy application with reference to the manager, the dummy application corresponding to a first application being temporarily inaccessible and being stored in an external storage medium. The controller is configured to control an operation based on the dummy application and a second accessible application managed by the manager.

Abstract: There is disclosed a high heat resistant aluminum alloy impeller, which is suitably used as an impeller, especially for a centrifugal compressor, and for the rotor and the blade of a turbo molecular pump or the scroll of a scroll compressor. Also, a method for manufacturing this aluminum alloy impeller is disclosed. The impeller is composed of an Al--Fe rapid solidification aluminum alloy, which is produced by a spray forming process for spraying a molten metal with inert gas and rapidly solidifying the metal at a cooling speed of 10.sup.2 .degree. C./sec. or higher while simultaneously deposing the metal. The rapid solidification aluminum alloy is subjected to hot extrusion processing within a temperature range of 200.degree. C. to 600.degree. C. and further subjected to hot forging.

Abstract: The present invention provides a heat resistant alloy having a composition consisting essentially of, in weight percentages, 4 to 12% of Fe, 1 to less than 4.0% of Si, 1 to 6% of Cu, 0.3 to 3% of Mg, and the balance aluminum and incidental impurities. The aluminum alloy may further contain one or more elements selected from 0.5 to 5 wt. % of V, 0.5 to 5 wt. % of Mo and 0.4 to 4 wt. % of Zr, the total content of these components not exceeding 8 wt. %. Since the heat-resistant aluminum alloys have a superior combination of properties of high tensile strength, good ductility and high fatigue strength at elevated temperatures up to 200.degree. C. as well as moderate temperatures, they can be applied to structural members, such as connecting rods, of internal combustion engines, thereby considerably reducing the weight of such structural components. The use of the alloys results in an increased output power and high efficiency in the internal combustion engines.
