  • CONVEYOR TABLE TRANSFER APPARATUS, TRANSPORT SYSTEM AND CONVEYOR TABLE TRANSFER METHOD
    Publication number: 20230055255
    Abstract: A conveyor table transfer apparatus includes a link mechanism connects the drive member driven by a motor (drive source) and a movable member supporting the movable linear conveyor. The link mechanism has one or more degrees of freedom. The degree of freedom of the link mechanism causes the link mechanism to bend in response to a degree of parallelization between the linear-motion guide rail and the linear-motion guide rail, making it possible to suppress load to be applied to the drive member or the movable member. As a result, it becomes possible to move the movable linear conveyor smoothly without requiring precise adjustment in mounting of the drive member and the movable member on the linear-motion guide rail and the linear-motion guide rail respectively.

  • Outboard motor
    Patent number: 11584497
    Abstract: An outboard motor includes an outboard motor body that, when located in a full trim-in position, an upper connecting pin is located in a lower limit position below a tilt shaft. When the outboard motor body is in a full tilt-up position, the upper connecting pin is located in the upper limit position above the tilt shaft. The upper connecting pin rotates around the tilt shaft at a first rotation angle from the lower limit position to a horizontal position at the same height as the tilt shaft. The upper connecting pin rotates at a second rotation angle around the tilt shaft from the horizontal position to the upper limit position. The second rotation angle is larger than the first rotation angle.

  • Straddled vehicle
    Patent number: 11541959
    Abstract: A straddled vehicle has a plurality of modes for engine brake controlling. The straddle vehicle includes a mode setter that selectively sets one of at least a normal mode and a first reduced mode that are included in the plurality of modes. An engine controller controls an electronic throttle valve and a fuel injector so that a torque of an internal combustion engine is equal to a target torque. When the torque of the internal combustion engine is less than zero while in the first reduced mode, an engine brake controller corrects the target torque by adding a first additive torque to the target torque. The first additive torque is set so as to be smaller as an amount of operation of an accelerator grip becomes larger so that an opening of the electronic throttle valve increases as the amount of operation of the accelerator grip increases.
