Abstract: Provided is a heterocyclic compound that can have an antagonistic action on an NMD A receptor containing the NR2B subunit and that is expected to be useful as a prophylactic or therapeutic agent for depression, bipolar disorder, migraine, pain, peripheral symptoms of dementia and the like. A compound represented by the formula (I), wherein each symbol is as defined in the DESCRIPTION, or a salt thereof.

Abstract: The present invention relates to an operation device which can be easily installed on a vehicle door, and a vehicle door comprising the operation device. An operation device of the present invention comprises: a gripper provided on an inner surface of a door of a vehicle; an operation interface provided on an inner side surface of the gripper for receiving an operation input entered by an occupant to operate at least one in-vehicle device; a first sensor provided on an outer side surface of the gripper for detecting a finger of the occupant; a second sensor provided on at least one of the inner side surface and an upper surface of the gripper for detecting a finger of the occupant; and a controller connected to the operation interface, the first sensor, the second sensor, and the at least one in-vehicle device.

Abstract: In a game medium passage detecting apparatus, optical sensors are arranged in correspondence with detection areas which are adjacent to one another in a cross direction of a game board surface. Each of the optical sensors has a light emitting element and a photoelectric detecting element. The light emitting elements and the photoelectric detecting elements are arranged such that the optical axis of the detection light extends in the direction which crosses a flat surface containing an axis extending in the depth direction of the game board surface parallel to the game board surface, crosses an axis perpendicular to the game board surface, and passes obliquely through the game board surface.

Abstract: In a game medium passage detecting apparatus, a plurality of optical sensors are arranged in correspondence to a plurality of detection areas which are set to be adjacent to one another in a cross direction of a game board surface. Each of the optical sensors has a light emitting element and a photoelectric receiving element. The light emitting elements and the photoelectric receiving elements are arranged such that the optical axis of the detection light extends in the direction which crosses a flat surface containing therein an axis extending in the depth direction of the game board surface in parallel with the game board surface and an axis intersecting perpendicularly the game board surface, and also passes obliquely through the game board surface.

Abstract: A plurality of medals are placed both on a fixed table and a movable table. A player supplies medals one by one on the movable table via a medal feeding rail. The movable table moves forward and backward in a reciprocating motion to drop medals placed on the fixed table into a medal outlet so as to give the medals to the player. A field table which is placed under the fixed table revolves around a tower, while containing a large number of medals accumulated therein, thereby circulating a large number of accumulated medals. Medals in the field table are automatically taken out, when the amount being in excess, by an overflow prevention device. Thus, the game machine permits the player to continue the game, free from concern about any medal overflowing from the field table.
