Abstract: A transfer apparatus comprises first and second rod-shaped members comprising a magnetic material; a driving device configured to rotate the first and second rod-shaped members about central axes of the first and second rod-shaped members, and a movable portion facing a part of side surfaces of the first and second rod-shaped members and comprising a magnetic material, the movable portion moving along the central axes of the first and second rod-shaped members when the driving device rotates the first and second rod-shaped members; a movable bearing capable of being coupled to the movable portion by a magnetic force, the movable bearing receiving a load from the first rod-shaped member and movable along the central axis of the first rod-shaped member in association with a movement of the movable portion; and a decoupling mechanism configured to decouple the movable bearing from the movable portion.

Abstract: A transfer apparatus comprises a rod-shaped member 2A that comprises a magnetic material, a cover 20A, made of a nonmagnetic material, that covers the rod-shaped member 2A, a first terminal member 22A configured to allow insertion of one end portion of the rod-shaped member 2A, a second terminal member 23A configured to allow insertion of the other end portion of the rod-shaped member 2A, and a driving device 4A, connected to the first terminal member 22A, that rotates the rod-shaped member 2A about a central axis of the rod-shaped member 2A, in which the rod-shaped member 2A and the first terminal member 22A are fixed to each other, the cover 20A and the first terminal member 22A are fixed to each other, the rod-shaped member 2A and the second terminal member 23A are not fixed to each other, and the cover 20A and the second terminal member 23A are fixed to each other.

Abstract: A transport apparatus includes a moving member, a shaft, a contact member, and an air damper. The moving member is moved along a table where an article is to be disposed. The shaft is rotatably connected to the moving member. The contact member is connected to the shaft and is to be brought into contact with the article. The air damper attenuates kinetic energy of the contact member and the shaft while the contact member and the shaft are being moved down toward the table.

Abstract: A temperature management apparatus is provided with: a temperature management furnace having a space in which an article is disposed and temperature is managed; bar-like members containing a magnetic material; facing members, each of which faces a part of the side surface of each of the bar-like members and contains a magnetic material; drive apparatuses, which rotate the bar-like members about their center axes and change the relative positions of the bar-like members and the facing members; and a contact member, which moves in the temperature management furnace in association with changes of the relative positions of the bar-like members and the facing members, and which moves the article by being in contact with the article. The drive apparatuses are disposed outside of the space in which temperature is managed.

Abstract: A grinding bar capable of stably staying a grinding part in a minute part of an affected part to execute a grinding and treatment in an environment having a large visual field is provided. This grinding bar to be mounted on a hand piece and used for grinding a tooth comprises a shank part 12 to be mounted on the hand piece, a tapered neck part 13 provided continuously to the shank part 12, a rod part B provided continuously to the neck part 13 and narrower and longer than the neck part 13, and an arrowhead-like or piece-like grinding part 15 formed by fixing diamond particles to the tip of the rod part B.
