Abstract: To provide a method for producing a fluorinated copolymer, whereby it is possible to efficiently produce a fluorinated copolymer in which coloration and foaming are suppressed during heating. A method for producing a fluorinated copolymer, comprising a step of producing a fluorinated copolymer by polymerizing tetrafluoroethylene and other monomer other than the tetrafluoroethylene in the presence of a hydroperoxide, at least one selected from the group consisting of a sulfite, a hydrogen sulfite, a dithionite, and a metabisulfite, at least one selected from the group consisting of an acidic substance and a substance that generates an acid by hydrolysis, and an aqueous medium.

Abstract: A method for manufacturing a semiconductor device includes forming, on first and second impurity layers on a termination region side, an insulating layer, forming a first metal film and a second metal film in this order on the insulating layer and a drift layer, performing dry etching on the first and second metal films all together so that a position of a first end of a metallized layer, which is a remaining part of the first metal film, in the interface region on the termination region side and a position of a second end of an electrode, which is a remaining part of the second metal film, in the interface region on the terminal region side are the same in plan view. The first and second ends are closer to the active region than an end of the second impurity layer on the termination region side in plan view.

Abstract: A vehicle frame structure includes a bumper reinforcement, a side structure that includes a first side wall on an outer side of the side structure in a vehicle width direction and a first protruding structure, and a crush box that is arranged between the bumper reinforcement and the side structure and includes a second side wall on an outer side of the crush box in the vehicle width direction, the second side wall having a second protruding structure. An edge line of the first protruding structure and an edge line of the second protruding structure are provided to be continuous in a vehicle front-rear direction, and a width in a vehicle up and down direction of the first protruding structure becomes wider farther away from the second protruding structure, in the vehicle front-rear direction.
