Abstract: An object of the present invention is to provide a clock screw having a deep interference film blue color that contributes to decorativeness while also having superior scratch resistance and corrosion resistance, and a method for producing the same. The means for solving provided by the present invention consists of: a clock screw comprising a screw base material made of steel containing carbon at 0.5% by weight to 1.0% by weight, an oxide layer of the steel on the screw base material having a thickness of 60 nm to 80 nm, and a fluorine coating film on the oxide layer; and, a method for producing the clock screw comprising: a step for preparing the screw base material, a step for forming the oxide layer by heating the screw base material for 30 minutes or longer at a temperature of 300° C. or lower in an air atmosphere, and a step for forming the fluorine coating film on the oxide layer.

Abstract: Disclosed is a beryllium-free copper alloy having high strength, high electric conductivity and good bending workability and a method of manufacturing the copper alloy. Provided is a copper alloy having a composition represented by the composition formula by atom %: Cu100-a-b-c(Zr, Hf)a(Cr, Ni, Mn, Ta)b(Ti, Al)c [wherein 2.5?a?4.0, 0.1<b?1.5 and 0?c?0.2; (Zr, Hf) means one or both of Zr and Hf; (Cr, Ni, Mn, Ta) means one or more of Cr, Ni, Mn and Ta; and (Ti, Al) means one or both of Ti and Al], and having Cu primary phases in which the mean secondary dendrite arm spacing is 2 ?m or less and eutectic matrices in which the lamellar spacing between a metastable Cu5(Zr, Hf) compound phase and a Cu phase is 0.2 ?m or less.

Abstract: An object of the present invention is to provide a game apparatus that can display an avatar matched to any kind of game in which the avatar participates, without changing clothes or decorations worn by the avatar to new clothes or decorations. The game apparatus specifies display data of items based on attributes set to the items and includes a design table where a correspondence relationship between the attributes and the display data of the items is set. Display data of the player character is generated based on the specified display data of the items, and the player character is displayed on a display screen based on the generated display data of the player character.

Abstract: An object of the present invention is to provide a game apparatus that can display an avatar matched to any kind of games that the avatar participates, without changing clothes or decorations worn by the avatar to new clothes or decorations. The present invention relates to a game apparatus that can play a plurality of games using a specific player character. The game apparatus includes an item display data specifier that specifies display data of items based on attributes set to the items and a design table where a correspondence relationship between the attributes and the display data of the items is set; a character display data generator that generates display data of the player character based on the specified display data of the items; and a character displayer that displays the player character on a display screen based on the generated display data of the player character.
