    摘要： The invention relates to the technical field of aircraft delivery, and discloses a delivery device, a set of delivery assembly and an aircraft. The delivery device includes a mounting part (1), a biasing part (2) and a blocking part (3). The mounting part (1) is provided with a mounting slot (11) of which the opening extends upward. The object to be delivered (100) can be hooked into the mounting slot (11). The biasing part (2) is configured to deform under the gravity of the object to be delivered (100) when it is lifted, which resets to drive the object to be delivered (100) out of the mounting slot (11) when the object to be delivered (100) falls to the ground. The blocking part (3) is configured to seal the opening of the mounting slot (11) when the object to be delivered (100) is not lifted and to open the opening of the mounting slot (11) when the object to be delivered (100) is lifted. The delivery device can realize the automatic dropping of the object to be delivered (100). It can limit the position of object to be delivered (100) which is prevented to fall out of the mounting slot (11). It can open the opening of the mounting slot (11) after lifting to enable the automatic unhooking of the object to be delivered (100) after they fall to the ground, which makes the delivery device easy to use and efficient in transporting the to-be-dropped object.

    摘要： Increase in weight of a rotary electric machine including a low-speed rotor in which a spacer made of metal is provided between a plurality of magnetic pole pieces, can be suppressed. The rotary electric machine includes a stator (10), a first rotor (20) provided so as to be rotatable with respect to the stator, and a second rotor (30) provided coaxially with the first rotor. The first rotor includes a plurality of magnetic pole pieces (21) disposed so as to be arranged in the circumferential direction, a plurality of spacers (22) respectively disposed between the plurality of magnetic pole pieces, two clampers (24) respectively disposed at both end portions in the axial direction, and a fastening tool (26) for fastening each spacer to a corresponding clamper. The spacer has a cavity portion (22a). The spacer and the fastening tool are electrically insulated from each other.

    摘要： Provided are a stage device, a charged particle beam device, and a vacuum device with which it is possible to increase the speed and acceleration of positioning and to suppress leakage of a magnetic field. To achieve this purpose, this magnetic levitation stage device is equipped with a levitating part, a non-levitating part, a horizontal thrust motor that imparts horizontal thrust to the levitating part when a coil current flows in a horizontal thrust coil, and a vertical thrust motor that imparts vertical thrust to the levitating part when the coil current flows in a vertical thrust coil, wherein: on the lower section of the levitating part, a vertical thrust assist yoke 6ZA is provided at a position facing the end section of the horizontal thrust coil protruding from a horizontal thrust yoke; and when the coil current flows in the horizontal thrust coil, simultaneously with the generation of horizontal thrust by the horizontal thrust yoke, vertical-direction assist thrust FZA is also generated by the vertical thrust assist yoke.

    摘要： The invention relates to a magnetic bearing assembly comprising a first magnet assembly (34) for generating a first quadrupole magnetic field on a first plane and a second magnet assembly (36) for generating a second quadrupole magnetic field on a second plane. The second plane is parallel to the first plane. Each of the quadrupole magnetic fields has a magnetic field axis, said axes being arranged at an angle to one another on the planes between four poles. A longitudinal axis (A) is defined by the centers of the quadrupole magnetic fields perpendicularly to the magnetic field axes. At least one diamagnetic element (44) is arranged on the longitudinal axis (A). The first and second magnet assembly (34, 36) are arranged relative to each other such that the first and the second quadrupole magnetic field are rotated relative to each other about the longitudinal axis (A) by an angular amount which is not a whole-number multiple of 90°. Such a bearing assembly can be used in particular in a magnetic levitation assembly with a lifting assembly.
