Abstract: A method and an apparatus for separating thigh meat and oyster meat from the thighbone can automatically separate thigh meat and oyster meat without detecting the boundary of the white cap at an end of the thighbone and the meat including thigh meat and oyster meat. The apparatus includes a cutter that is inserted into the detected boundary part in the final operation of deboning a thigh-with-bone of an edible beast and bird. The apparatus has a clamper, a guide-with-a-groove device, and a guide-with-a-cutter device downstream of the guide-with-a-groove device provided on the transfer line of the clamper. Both guide devices are provided such that the open end side of each guide device, which is Y-shaped is directed toward upstream of transfer of the clamper.

Abstract: An immersion nozzle for steel continuous casting has two delivery ports opposing each other and has one or more bore reduced portions above the delivery ports in a bore. A bore reduced portion closest to the delivery ports has an elliptical horizontal section, with an elongate direction of the ellipse nearly parallel with a direction of the delivery ports. The bore elliptic reduced portion may include another bore reduced portion second closest to the delivery port, wherein a lower end surface of the bore elliptic reduced portion closest to the delivery port can be 0.3H-2H of a delivery port height H of from an upper end of the delivery port, the spacing to the upper bore elliptic reduced portion being 0.3D-2D of a diameter D of the bore, and moreover a length of each bore reduced portion being 0.5D-5D.
