Abstract: A coin feeding apparatus comprising: a disk that includes a plurality of protrusions on a surface of the disk, is disposed to be inclined and rotatable, and, when rotating, causes a first coin or a second coin to be caught on and carried upward by the plurality of protrusions, the second coin having a diameter greater than that of the first coin; a cover that forms, between the cover and a surface of the disk, a space for storing a coin therein; and a separation unit that separates one coin out of two of the first coins from the plurality of protrusions so as to cause the one coin to fall into the space, the two first coins being caught on the plurality of protrusions side by side.

Abstract: A device for fixing biological soft tissue is endowed with strength and deformation performance for being used as a device for coupling biological soft tissue that has been cut or separated due to an incision or the like during a surgical procedure, and is completely degraded in vivo and discharged after adhesion of the soft tissue or after healing of the incision tissue. The device is composed of a ternary Mg alloy material of Mg—Ca—Zn. In the Mg alloy material, the Ca and Zn are contained within the solid-solubility limit with respect to the Mg. The remainder is composed of Mg and unavoidable impurities. The Zn content is 0.5 at % or less. The Ca and Zn content has a relationship of Ca:Zn=1:x (where x is 1 to 3) by atom ratio. The crystal grain structure is equiaxed, the crystal grain size according to linear intercept being 30 to 250 ?m.
