  • Patent number: 10583579
    Abstract: A field-pole magnet manufacturing apparatus fractures a magnet fixed on a die serving as a lower tool by causing a punch of an upper tool to press the magnet while in contact with the magnet. At least one projection is formed in the punch of the upper tool symmetrically with respect to the central position of the magnet in the width direction of the magnet.
    Type: Grant
    Filed: September 20, 2012
    Date of Patent: March 10, 2020
    Assignee: NISSAN MOTOR CO., LTD.

  • Patent number: 9796150
    Abstract: A field-pole magnet manufacturing apparatus manufactures magnet pieces that constitute a field-pole magnet arranged in a rotary electric machine by fracturing the magnet. This manufacturing apparatus includes: a support unit on which the magnet is placed; a fracture unit that is arranged opposite to the support unit across the magnet and is configured to fracture the magnet by pressing the magnet while in contact with the magnet; and a powder removal unit that is configured to remove crush powder produced by fracture of the magnet.

  • Publication number: 20060267980
    Abstract: The CAD system includes primary-geometric data extraction means for extracting primary geometric data from a CAD object selected; primary-geometric-condition determination means for deriving a geometric condition from the primary geometric data; automatic recognition means for performing automatic recognition of a CAD object that satisfies the geometric condition with respect to the selected CAD object; secondary-geometric data extraction means which extracts secondary geometric data from the additionally selected CAD object; and secondary-geometric-condition determination means for deriving a geometric condition from the secondary geometric data. The automatic recognition means performs automatic recognition of a CAD object that satisfies the geometric condition derived by the secondary-geometric-condition determination means with respect to the first selected CAD object, the automatically recognized CAD object that satisfies the first derived geometric condition, and the additionally selected CAD object.
