摘要： The production apparatus is used in production of single crystals by solution growth techniques. The production apparatus includes a seed shaft, a crucible, and a drive source. The seed shaft has a lower end surface to which a seed crystal is to be attached. The crucible contains a solution from which a single crystal is made. The drive source causes the crucible to rotate, and also varies the rotational speed of the crucible. The inner peripheral surface of the crucible includes a flow control surface which defines a non-circular cross-sectional shape. This single crystal production apparatus is capable of strongly stirring the solution contained in the crucible.

摘要： An apparatus (10) for producing an SiC single crystal is used in the solution growth includes a seed shaft (28) and a crucible (14). The seed shaft (28) has a lower end surface (28S) to which an SiC seed crystal (32) is to be attached. The crucible (14) holds an Si—C solution (15). The seed shaft (28) includes a cylinder part (28A), a bottom part (28B), and a low heat conductive member (28C). The bottom part (28B) is located at the lower end of the cylinder part (28A) and has the lower end surface (28S). The low heat conductive member (28C) is arranged on the upper surface of the bottom part (28B) and has a thermal conductivity lower than that of the bottom part (28B). This production apparatus can make the temperature within the crystal growth surface of the SiC seed crystal less liable to vary.

摘要： A manufacturing method for a bent member of the present invention includes a holding step of holding one end portion of a long steel material having an opening end in a longitudinal direction by a chuck, a feeding step of feeding the steel material in the longitudinal direction with the one end portion as a head after the holding step, a heating step of performing high-frequency induction heating on a portion of the steel material in the longitudinal direction to form a heated portion, a bending step of moving the chuck in a three-dimensional direction to apply a bending moment to the heated portion, and a cooling step of injecting a cooling medium to the heated portion to cool the heated portion after the bending step. When the heating step is started, the chuck is cooled by the cooling medium in a state where a heating amount applied to the one end portion when the heated portion is formed on the one end portion is greater than that of an upstream side adjacent portion adjacent to the upstream side of the one end portion as seen along a feeding direction of the steel material.
