    摘要: [Problem] A method for manufacturing a bent hollow pipe is provided, in which even when a three-dimensionally bent pipe is formed, a gap, an uneven thickness, and the like would not occur at contact portions at the ends of both of the flange portions when press work is finished, and thus a pipe having the high quality contact portions can be formed.[Solution] In a method for manufacturing a bent hollow pipe, a material W, which is to be processed and which is a flat plate extending a first plane formed by a first direction and a second direction perpendicular to the first direction, is pressed in a stepwise manner using a plurality of forming dies from a third direction perpendicular to the first plane, so that two sides of a second plane formed by the second direction and the third direction of the material W are brought into contact with each other, and the bent hollow pipe is made to be bent and extend in a three dimensional manner that is bent in the first plane and in the second plane. The method includes a step in which a push out portion 13 is formed that is pushed out onto the material W in the third direction and that is bent and extends within a third plane formed by the first direction and the third direction in a press work, and extension portions 15 are formed to extend away from each other at both sides which sandwich the push out portion 13 of the material W, and flange portions 16 are formed that are bent, in a direction opposite to a push out direction of the push out portion 13, at ends of the extension portions 15, a step in which while bending is maintained between the extension portions 15 and the flange portions 16, a bent portions 17 between the push out portion 13 and the extension portions 15 are bent in the opposite directions, so that the both of the flange portions 16 are formed in a direction in which the both of the flange portions 16 face each other, a step in which the both of the flange portions 16 of a three-dimensionally bent portion P that is bent in the first plane and in the second plane are bent and brought closer to each other as compared with both of the flange portions 16 in a portion other than the three-dimensionally bent portion P, and a step of bringing ends of the flange portions 16 into contact with each other.

    摘要: The semiconductor device is formed in the form of a GaN-based stacked layer including an n-type drift layer 4, a p-type layer 6, and an n-type top layer 8. The semiconductor device includes a regrown layer 27 formed so as to cover a portion of the GaN-based stacked layer that is exposed to an opening 28, the regrown layer 27 including a channel. The channel is two-dimensional electron gas formed at an interface between the electron drift layer and the electron supply layer.
