Abstract: [Problem] An object of the present invention is to provide frozen renal cells which have high cell viability after thawing and in which physiological functions of the kidney are maintained, and a renal cell culture in which the physiological functions of the kidney is maintained. [Solution] A method of producing frozen-state renal cells includes: a recovery step of recovering cultured renal cells; and a freezing step of freezing the renal cells recovered in the recovery step, in which the renal cells are recovered as an aggregate in the recovery step, and the aggregate is frozen while an aggregated state of the aggregate is substantially maintained in the freezing step.

Abstract: A game apparatus includes a pusher configured to reciprocate forward and backward on a surface of a table, the pusher including a first surface that is an upper surface of the pusher; a feeder configured to feed a game object that is rollable regardless of an orientation of the game object, onto the first surface; and a suppressor provided on at least one of the pusher and the table and configured to suppress an amount of movement of the game object.

Abstract: A game apparatus provides a game using three-dimensional game objects rollable regardless of their orientation, and includes a circulating mechanism configured to circulate the three-dimensional game objects. The circulating mechanism includes: a conveyor device configured to transport the three-dimensional game objects from a first position to a second position higher than the first position; a first path configured to move the three-dimensional game objects from the second position to a third position lower than the second position; a supply path for supply of a part of the three-dimensional game objects to a game object utilizer that uses the supplied three-dimensional game objects in the game, the part entering the supply path at a position between the second position and the third position; and a second path configured to move a part of the three-dimensional game objects not entering the supply path, to the first position lower than the third position.

Abstract: A conveyor device includes a supporter extending from a first end of a rotation axis to a second end thereof in a helical manner relative to the rotation axis, an encircling member that encircles at least a third portion of the supporter, the third portion being a portion between a first portion on the first end and a second portion on the second end, and at least one guide for a three-dimensional game object to move from the first end to the second end along with rotation of the supporter, the at least one guide extending from the first end to the second end within a gap between the supporter and the encircling member and being configured such that the guide in coordination with the supporter and the encircling member supports the three-dimensional game object when the three-dimensional game object moves from the first end to the second end.
