To provide a game device that can reduce the size of the device and can execute the simulation of a match game scene based on an operation input by a game player.A field panel 9 imitating a field of a sporting event, card holding stages 10 that are arranged in the locations indicating the positions of players in the sporting event on the field panel 9, and holding card 11 in a raised state, a card information reading means for reading card information recorded on the cards 11 held by the card holding stages 10, and a game execution control means for controlling the execution of a game are provided. Further, the game execution control means includes a means for controlling, based on the card information read by the card information reading means, the execution of the simulation of the match game scene, which is displayed on the touch panel 6 based on the operation by the game player, to be a predetermined number of times that is set in advance.

A sealing ring (21) used for reciprocating motion and having low friction characteristics. The sealing ring is held at one of two members that move relative to each other and slidably in intimate contact with the other. The sealing ring (21) has an end sliding part (21a) having an arcuate cross section and slidably in intimate contact with the other and also has a recessed surface (21c, 21d, 21e) formed in at least either a rear face or both side faces in an axial direction. The sealing ring (21) satisfies the relationships of A/2 and 0.5A

Provided is a process for producing a silane coupling agent, which can shorten the time required for the production process. A process for producing a silane coupling agent, characterized by comprising a step of reacting a silane compound (A) with a compound (B) which has a hydroxyl group and further contains an atom having an unshared electron pair other than an oxygen atom derived from the hydroxyl group, in the presence of a metal-containing catalyst (m) to obtain a silane compound (C) which has an alkoxyl group containing the atom having the unshared electron pair other than the oxygen atom derived from the hydroxyl group.
