  • Publication number: 20150371920
    Abstract: Semiconductor elements work for power conversion and generate heat. A plurality of heat-radiating fins are juxtaposed at intervals to form a passage in a first axis direction, receive the heat from the semiconductor elements, and expel the heat into the air flowing through the passage. A first protective fin has an end face having an equal length in the juxtaposition direction to and mutually facing the end face on the first axis positive side of at least some of the heat-radiating fins, and extends in the first axis positive direction from that end face. A second protective fin has an end face having an equal length in the juxtaposition direction to and mutually facing the end face on the first axis negative side of at least some of the heat-radiating fins, and extends in the first axis negative direction from that end face.

  • Publication number: 20120147175
    Abstract: A method for producing composite material components is provided with a process of laminating fiber-reinforced plastic tape. The method includes, at a plurality of sites from an attachment starting site to an attachment ending site of a first fiber-reinforced plastic tape, determining an attachment state of the first fiber-reinforced plastic tape during lamination of the fiber-reinforced plastic tape. The lamination is stopped when it is determined that the first fiber-reinforced plastic tape overlaps with a second fiber-reinforced plastic tape at a first site of the plurality of sites and that a gap exists between the first fiber-reinforced plastic tape and the second fiber-reinforced plastic tape at a second site of the plurality of sites. And, the lamination is continued when it is determined that the first fiber-reinforced plastic tape overlaps with the second fiber-reinforced plastic tape at all of the plurality of sites.
