  • Publication number: 20240149660
    Abstract: A drive unit for a vehicle may include a motor, a casing accommodating the motor, an electric pump unit attached to a lower part of the casing and configured to circulate heat medium within the casing and a filter unit attached to the lower part of the casing and configured to filter the heat medium. At least a part of the electric pump unit and at least a part of the filter unit each protrude outside the casing. Outside the casing, the filter unit is adjacent to the electric pump unit from a front in the vehicle.

  • Publication number: 20240136897
    Abstract: A magnet array method that can improve assemblability of magnets is provided. A magnet array method according to an aspect of the present disclosure is for arraying a plurality of magnetized magnets using a magnet array jig and includes disposing magnetic force parts of the magnet array jig at positions facing magnets to be arrayed, and arraying the magnets. The magnetic force parts are disposed so as to impart, to the magnets to be arrayed, a magnetic force for cancelling a force acting on the magnets to be arrayed.

  • Publication number: 20240120788
    Abstract: A magnet arrangement method capable of easily assembling magnets is provided. A magnet arrangement method according to one aspect of the present invention is a magnet arrangement method for arranging a plurality of magnetized magnets in a Halbach array, the method comprising: a process of forming a first magnet group by combining magnets in such a way that a direction of a magnetic force that acts on the magnets is oriented in a first direction; a process of forming a second magnet group by combining magnets in such a way that the direction of a magnetic force that acts on the magnets is oriented in a second direction that is opposite to the first direction; and a process of assembling a plurality of the first magnet groups and a plurality of the second magnet groups.

  • Patent number: 6742220
    Abstract: A nozzle unit for an electric vacuum cleaner has a body case with a nozzle open toward a surface to be cleaned, a first pipe coupled to the body case so as to be rotatable in the direction, and a second pipe coupled to the first pipe so as to be rotatable in the direction. A first and a second air flow passage, formed inside the first and second pipes respectively, are arranged substantially in a straight line as seen in a side view. The first pipe has a sliding portion that has an arc-shaped cross section and that slides along the inner surface of the body case, and this sliding portion is arranged inside the body case, which is substantially rectangular, as seen in a plan view.
