  • Patent number: 10622864
    Abstract: An electric motor unit includes an electric motor and a connection module. The electric motor includes motor coils, a stator and a rotor. The electrical connection module includes a power feed bus bar and a neutral bus bar. The power feed bus bar includes power feed collars for each phase, in which terminal portions for each phase are arranged. The neutral bus bar includes a neutral collar in which neutral terminal portions are arranged. When viewed in a direction intersecting with a second cross section, which intersects with a first cross section containing all the neutral terminal portions, the minimum distance between a second cross-section neutral terminal row on the second cross section and a second cross-section power feed terminal row on the second cross section is greater than zero.

  • Patent number: 10334090
    Abstract: An electronic device includes a first housing, a second housing, a first hinge that is flexible and connects the first and the second housings, and a display panel that is continuously flexible. The first hinge overlaps with a first housing wall of the first housing and a second housing wall of the second housing. The first housing includes a first magnetic body. The second housing includes a second magnetic body. When the first hinge is in an open state, causing the first housing and the second housing to be disposed side-by-side, a magnetic force in a first direction is produced between the first magnetic body and the second magnetic body.

  • Patent number: 9680254
    Abstract: A connector includes a holding member which is formed with two accommodation portions, a middle portion and regulating portions. Flat plate portions which form a mid-plate are accommodated by the accommodation portions, respectively. Each of the flat plate portions has a base portion, a press-fit portion, a spring portion, a lock portion and a regulated portion. The press-fit portion protrudes from the base portion in a pitch direction and is pressed against the holding portion. The spring portion extends forward from the base portion and has resilience. The spring portion is apart from the regulating portion in the pitch direction. The lock portion is supported by the spring portion and protrudes outside the mating portion in the pitch direction. The regulated portion extends forward from the base portion and is situated inward of the regulating portions in the pitch direction.

  • Patent number: 9233608
    Abstract: When both a left rear wheel and a right rear wheel are driven by first and second electric motors, and acceleration slippage occurs at either the left wheel or the right wheel, the acceleration slippage is reduced by decreasing the command motor torque (power drive torque) of the first or second electric motor connected to the wheel at which acceleration slippage was generated. The command motor torque of the first or second electric motor connected to the other wheel (wheel on the other side) on the right or left side that is opposite the wheel at which slippage occurred is increased, thereby making it possible to supplement the decrease in the driving torque of the wheel at which slippage occurred.
