Abstract: Provided is a surface-coated metal porous body having a three-dimensional network structure, the surface-coated metal porous body including: a framework forming the three-dimensional network structure; and a coating film provided on a surface of the framework, wherein the framework has a body including a metal element as a constituent element, the coating film includes a scale-like carbon material and a fine-grained conductive material, a distance D between two points that are farthest from each other on an outer perimeter of a main surface of the scale-like carbon material is 5% or more and 120% or less relative to a thickness of the framework, and the scale-like carbon material is deposited on the surface of the framework.

Abstract: When a game is started, the game execution time is counted by a counter and a determination is made as to whether or not the execution time coincides with a timer value which is set before the game is started, so that the game is forcibly ended upon coincidence. When the game is forcibly ended, the game content before the ending is preserved. Thus, it is not necessary to do the game all over again, in order to restart the game.

Abstract: A solder ball supply device comprising flux supply means 200 which supplies flux at the same time to input and output terminals on substrate 1 prior to supply of solder balls, and solder ball supply means 300 which takes out a number of solder balls from discharger 350 in which solder balls are held matrixwise at the same time in the same pattern as the pattern of said input and output terminals and supplies solder balls to said input and output terminals to which flux has been supplied.
