Abstract: An in-terminal display device causes at least one first icon to appear and displays the at least one first icon in at least one of a plurality of areas. An in-terminal input device receives an operation of switching areas and an operation of selecting a first icon. An in-terminal controller or an in-server controller controls a game corresponding to a selected first icon such that the game can be played when any one of first icons is selected in a switched area. The in-terminal controller of the in-server controller limits the number of first icons to be caused to appear to an upper limit value or less.

Abstract: The disclosed game control device is a device executing a game that simulates a sport or an amusement in the real world. The device includes: a setter configured to set a situation in a sport or an amusement before an event on the game; an event generator configured to generate the event based on information of an operational input under the situation set by the setter; and a result generator configured to generate a game result based on the situation set by the setter and the event generated by the event generator.

Abstract: The game control device may include a storage unit, a first match-up executing unit, a character ability updating unit, and a second match-up executing unit. The storage unit stores an ability value of each player character. The first match-up executing unit executes a first match-up between two player characters in response to input of a communication terminal, and to determine a result of the first match-up based on the stored ability value of each player character. The character ability updating unit updates, based on the result of the first match-up, the ability values of the two player characters, and causes the storage unit to store the updated ability values. The second match-up executing unit executes a second match-up between player characters independently from the first match-up without input of the communication terminal, and determines a result of the second match-up based on the stored ability value of each player character.

Abstract: The present invention relates to a face structure of a hollow-body, metal golf club head, comprising a face of laterally elongated shape, a crown and a sole plate fixed thereto, and particularly to a face structure having thin-walled areas for extended, stable carry and horizontally stabled trajectory. The face 11 has a thick-walled area 15a of uniform thickness formed at the backside thereof, which extends from the heel side to the toe side thereof over the hitting area 16a, and with thin-walled areas 15b, 15c of uniform thickness formed above and below the thick-walled area 15a. An elongated portion 17 for fixing the crown and the sole plate is formed projecting backward on the backside periphery of the face 15.

Abstract: A racket which is capable of mitigating the shock transmitted to the handle, improving the stability of the face of the head-frame, and enhancing the ability to damp the vibration imparted to the frame upon impact is disclosed. The racket has two meshed pieces (5) integrally attached to the surface of each of the lateral sides of a head-frame (1) so that the meshed pieces (5) are opposed to each other across the sweet spot of the racket. The meshed piece (5) is made from titanium and has a predetermined shape.

Abstract: A golf club head of simple structure is provided, in which tungsten balance weights can be fixed to a titanium sole plate with a sufficient bonding strength. A golf club head 2 includes a hollow shell made of titanium or titanium alloy. The shell has a main body 4, a sole plate 6 and a face plate 8 which are integrally welded. Balance weight members 10 made of tungsten are provided on the sole plate 6 as press-fitted into holes 12 arranged between the toe side 6a and the heel side 6b of the sole plate 6. The balance weight 10 is a disk-like shape and integrally has a flange 10a extending radially at an upper end thereof. The flange 10a provided at an upper end of each balance weight member 10 abuts to the inner surface of the sole plate 6. Also, there is provided a metal plate 14 which covers and abuts the upper portions of the balance weights 10.

Abstract: An iron golf club head comprised of a head body 10 made of light metal such as titanium and containing a plurality of weight members 16.

Abstract: In a tennis racket whose frame and handle shaft are integrally made of fiber reinforced plastics and the frame defines a strung surface, the frame is so designed that its first thickness "t" in a direction of the strung surface is substantially uniform around the circumference of the frame and its second thickness "T" in a direction perpendicular to the strung surface is gradually varied. The second thickness is maximum at side sections of the frame interposing a sweet spot in the strung surface and is minimum at the top and bottom portions of the frame in such a manner that the maximum thickness is thicker in the range from 35% to 60% than the minimum thickness, which increases a weight per unit length of the frame toward the side sections.
