Abstract: A method for the refining of glass by means of high temperatures in a skull crucible is provided. The method includes introducing a glass melt in the skull crucible through an inlet disposed at an upper region of the skull crucible, heating the skull crucible by irradiation of high-frequency energy, and discharging the glass melt from the skull crucible through an outlet disposed at the upper region, the outlet being disposed at a place essentially lying opposite the inlet.

Abstract: A hypervideo player for playing hypervideos containing both video and hypervideo hyperlinks provides user selectable run-time options for the form of hypervideo hyperlink emphasis region display attributes displayed at the time of viewing. The hypervideo player may reside on a host system. The hypervideo player integrates video file(s) and hypervideo hyperlink data file(s) to form a hypervideo. The hypervideo player decodes a video file, encodes the decoded video file with a corresponding hypervideo hyperlink data file at key frames of the video file to form a hypervideo, displays the hypervideo on a display device and provides the user, at the time of viewing, with at least one user selectable option for the form of hypervideo hyperlink emphasis region display attributes. The hypervideo player preferably employs interpolation between key frames to determine the display position of the hypervideo hyperlink emphasis region(s) in non-key frames of the hypervideo.

Abstract: In a method for manufacturing Ni—Al alloy powders for electrode materials of fuel cells, in which, using aluminum chloride (AlCl3) as a catalyst, powders of Ni and Al, that have been used as electrode materials, are chemically reacted with each other to diffuse the Al into the Ni powders, so that Ni—Al alloy powders can be manufactured at a low temperature below fusion points of Ni and Al while maintaining a shape and a size of the existing Ni powders as they are, thus providing a manufacturing process of Ni—Al alloy powders that is simple, economical, compatible in working, and ready for scale-up, and in which a conventional manufacturing process of electrode based on Ni is used as it is, so that large sized electrode is manufactured.
