Abstract: A game system 100, which is an example of a matching system, includes a game server 500 and a plurality of game devices 300 that are connected to the game server 500 over a network. The game system 100 includes a related player presenting section 331 for presenting, to a participating player who is attempting to join a game and for whom matchmaking is to be performed in any of matching rooms that are matching ranges, a related player related to the participating player, a matching room identification section 54 for identifying a matching room that is associated with the related player presented by the related player presenting section 331, and a matching processor 55 for performing matchmaking in the matching room identified by the matching room identification section 54.

Abstract: A method for manufacturing a grinding wheel which is formed by fitting a cylindrical grindstone chip including abrasive grains to a base metal formed to be of a columnar shape, comprises an adhesive agent applying step, a linear guide member arranging step for arranging and attaching a plurality of linear guide members on at least one of the outer peripheral surface of the base metal and the inner peripheral surface of the cylindrical grindstone chip, in parallel with a rotation axis of the base metal and with an equal distance separated in a circumferential direction from one another and a base metal and grindstone chip fitting step for fitting the base metal and the cylindrical grindstone chip to each other by relatively moving the base metal and the cylindrical grindstone chip, interposing therebetween the plurality of linear guide members arranged and attached with the equal distance separated from one another.

Abstract: A game apparatus detects an input position, on an input plane, at which an input operation has been performed. The game apparatus also detects an operation sound that occurs due to the input operation performed on the input plane. The game apparatus evaluates the detected operation sound, and obtains a result of the evaluation (e.g., volume of the operation sound). The game apparatus performs game processing by using the detected input position and the result of the evaluation. This enables the game apparatus to perform more complex processing by using a touch operation as input information, and allows a player to provide more complex instructions based on the touch operation.
