Abstract: A battling stadium game apparatus and methods for toy tops providing multiple play level surfaces which may include platform inserts to actively direct interactions of spinning tops across multiple play level surfaces, a base, concave areas at a first play level surface at the base, concave areas with battling surfaces at the first play level. The battling surface includes a middle area and a periphery area surrounding the middle area, an overdrive surface disposed at a second play level surface at the base, the overdrive surface is at a level elevated from the concave arena. A lid nests within the base and defines an exterior wall around the perimeter of the base, with a third level platform element between the base and the lid for a third play level surface.

Abstract: A top toy includes a shaft part, a trunk part, and a top tip cover. The trunk part is detachably configured on the shaft part. The top tip cover is detachably configured on the shaft part at a longitudinal end. The shaft part includes a first engagement part being movably configured between a raised position and a lowered position in an axial direction and a second engagement part. The top tip includes a third engagement part being configured to be engaged by rotating in a first direction with the second engagement part to prevent the shaft part from separating from the trunk part in the axial direction. The top tip cover includes a fourth engagement part being configured to be engaged with the first engagement part to prevent the top tip cover from rotating in a second direction with respect to the shaft part.

Abstract: A semiconductor memory device of an embodiment includes: a first stacked body in which a plurality of first conductive layers is stacked via a first insulating layer; a second stacked body in which a plurality of second insulating layers is stacked via the first insulating layer, the second stacked body being surrounded by the first stacked body; and a pair of first plate-like portions extending in a stacking direction and in a first direction intersecting the stacking direction, the pair of first plate-like portions being disposed between the first and second stacked bodies on both sides of the second stacked body in a second direction intersecting the stacking direction and the first direction. The pair of first plate-like portions each has a first side wall facing the first stacked body and including a metal element-containing layer in contact with an end surface of the first insulating layer of the first stacked body.

Abstract: A first locking mechanism is configured to block rotating the first and second holders by locking an operation component or by locking the first and second holders when the cap is not mounted on one of the first and second holders, and is configured to unlock rotating the first and second holders by being engaged with the cap when the cap is mounted on one of the first and second holders and when the cap is arranged to face upwardly towards a upper side. A second locking mechanism is configured to block rotating the first and second holders by locking the operation component or by locking the first and second holders when the cap is mounted on one of the first and second holders and when the cap is arranged to face downwardly to a lower side opposite to the upper side.

Abstract: A cap shooting toy includes a toy body, a pushing member, a shooting device, and a magazine. The toy body includes a loading unit in which a first ceilinged cylindrical cap is loaded. The pushing member is configured on the toy body to push the first ceilinged cylindrical cap from the loading unit in a shooting direction to a shooting position. The first ceilinged cylindrical cap is shot prior to a second ceilinged cylindrical cap in the shooting direction. The shooting device includes a pair of flipping pieces extending in the shooting direction. The magazine abuts the toy body and is configured to supply the first and second ceilinged cylindrical caps to the loading unit. The first and second ceilinged cylindrical caps have first and second circumferential periphery respectively. The first and second circumferential periphery abut to each other when in the magazine.

Abstract: A spinning top toy for spinning on a surface includes a shaft part and a body. The shaft part includes a shaft part body and a ground contact part being integrally formed with the shaft part body. The shaft part extends in an axial direction. The body is configured on the shaft part. The ground contact part includes a wheel-shaped body being slidably configured on the shaft part body. The wheel-shaped body is configured to be moved to a first position, and is configured to be moved to a second position. The second position is closer to the surface than the second position in the axial direction. The wheel-shaped body is configured to be in contact with the surface when at the second position.

Abstract: The spinning top launching device includes a rotary drive mechanism being configured to be rotated by the operation member and configured to apply rotary force to the spinning top, a rotation speed detection mechanism including a centrifugal clutch mechanism being configured to be rotated by the operation member, and an operation body being engaged with an output side of the centrifugal clutch mechanism to be moved in a first direction from a predetermined position. The operation body includes an indication part configured to indicate the rotation speed.
