Abstract: A tungsten electrode material contains a tungsten-based material and oxide particles dispersed in the tungsten-based material. The oxide particles are composed of an oxide solid solution in which a Zr oxide and/or an Hf oxide and an oxide of at least one rare earth selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu are dissolved as a solid solution. A content of the rare-earth oxide with respect to a total amount of the Zr oxide and/or the Hf oxide and the rare-earth oxide is not lower than 66 mol % and not higher than 97 mol %, a content of the oxide solid solution is not lower than 0.5 mass % and not higher than 9 mass %, and the remainder is composed substantially of tungsten.

Abstract: A Mo—Si—B-based alloy for a heat-resistant alloy that satisfies, more than conventional, physical properties such as proof stress and hardness adapted to an increase in the melting point of 5 a welding object. The Mo—Si—B-based alloy powder is such that the full width at half maximum of (600) of Mo5SiB2 in X-ray diffraction peak data is 0.08 degrees or more and 0.7 degrees or less.

Abstract: The purpose of the present invention is to provide a solution for use in the extraction of cobalt, whereby it becomes possible to extract cobalt at lower cost and more safely compared with a case in which a conventional one is used. The solution for use in the extraction of cobalt according to the present invention comprises: an ionic liquid containing a quaternary ammonium group; and an organic solvent which exists in such a state that the organic solvent is mixed with the ionic liquid and which has a kauri-butanol value of 60 or more.

Abstract: Provided is a tungsten electrode material that can improve the life of an electrode than conventional by the use of a material in place of thorium oxide. The tungsten electrode material includes a tungsten base alloy and oxide particles dispersed in the tungsten base alloy, wherein the oxide particle is an oxide solid solution in which a Zr oxide and/or a Hf oxide and an oxide of at least one or more kinds of rare earth elements selected from Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu are solid-dissolved.

Abstract: A model managing apparatus manages an intellectual property model formed by using program description to model a function to be realized as hardware. The model managing apparatus includes a data storing unit that stores and manages therein electronic system levels that are components into which the intellectual property model is divided. The components are an application program interface that defines external communications, a register that defines data to be input and output, and a behavior that defines a function or a computation. The data storing unit further stores therein connection data that defines connection relations between the register and the behavior, between behaviors, and between the behavior and the application program interface.
