  • Patent number: 11427088
    Abstract: A movable structure driving unit is a movable structure driving unit used for a movable structure, including: an electric motor that is electrically connected to a power supply and that drives a front wheel; a rear-side motive power source that drives a rear wheel; a jump detector that detects a jump of the front wheel from ground; and a motor controller that controls driving of the electric motor. The motor controller stops supply of a driving current from the power supply to the electric motor when the jump of the front wheel from the ground is detected in a state in which driving of the front wheel and the rear wheel is instructed.

  • Publication number: 20210402760
    Abstract: An ink discharge operation adjustment method includes the following, recording a halftone image in which the ink is discharged to form a predetermined halftone pattern and a solid image in which the ink completely covers a surface of the recording medium; obtaining a first reading result by a reader reading a non-recording region in which an image is not recorded on a recording medium; obtaining a second reading result of the halftone image and the solid image so that a difference of an elapsed time from a start of the curing to the reading is within a predetermined reference difference; obtaining coverage rate information based on the reading results; and performing setting regarding adjustment of a droplet amount of the ink based on the coverage rate information.

  • Patent number: 10871178
    Abstract: A transaxle includes a braking unit disposed in the transaxle casing, the braking unit configured to brake the axle. The braking unit includes an operating shaft projecting from one side of the transaxle casing. A link mechanism of the transaxle is includes a relay arm rotatably pivoted on a shaft provided on the one side of the transaxle casing, a brake arm fixed to the operating shaft, the brake arm being configured to rotate between a braking position and an unbraking position of the braking unit together with the operating shaft, a first link configured to manipulate the relay arm, and a second link configured to join the relay arm to the brake arm. The link mechanism constrains motion of the brake arm through the second link such that an external force on the braking unit cannot cause an unexpected release from the braking state.

  • Patent number: 10711887
    Abstract: A transaxle includes a continuously variable transmission including a speed control arm and a neutral return spring allowing a biasing force to act on the speed control arm toward a neutral position, the speed control arm configured to operate from the neutral position to a forward position or a backward position to perform a continuous speed variation. The biasing force does not act on the speed control arm when the neutral return spring ranges from the neutral position to a predetermined speed position on a forward movement side, and the biasing force acts on the speed control arm when the neutral return spring ranges from the predetermined speed position to a maximum speed position on the forward movement side.

  • Patent number: 10591036
    Abstract: A compact transaxle is provided with a multi-speed transmission mechanism having transmission shafts extended in a longitudinal direction so that the transaxle can be combined with an engine having a crankshaft in the longitudinal direction. A bevel gear serving as an output member of the multi-speed transmission mechanism having the transmission shafts meshes with a bevel gear provided on a speed-reduction intermediate shaft extended parallel to a pair of differential yoke shafts of a differential mechanism extended in a lateral direction. A single transaxle casing incorporates the multi-speed transmission mechanism, the differential mechanism, and a speed-reduction mechanism including the speed-reduction intermediate shaft, thereby constituting the transaxle.
