  • Publication number: 20200055489
    Abstract: The present invention comprises an AS-side wiper motor 40 including an AS-side output shaft 83 that is rotated in forward and backward directions and a link mechanism 60 constituted by a four-bar link. The AS-side wiper member 50 is configured to wipe in a first AS-side wipe range 11b by a pivotal movement of the AS-side output shaft 83 in a first angular range SA1, and wipe in a second AS-side wipe range 11c by a pivotal movement of the AS-side output shaft 83 in a second angular range SA2 that differs from the first angular range SA1. The wipe range of the AS-side wiper member 50 can thus be switched between the first AS-side wipe range 11b and the second AS-side wipe range 11c by controlling an angular range, in which the AS-side output shaft 83 is pivotally moved, to be in the first angular range SA1 or the second angular range SA2 that differ from each other.

  • Publication number: 20190383240
    Abstract: Occlusion diagnosis of a vent passage is executed with high accuracy based on an estimated value of the volume of a sealed space. An occlusion diagnosis device includes a diagnosis unit for the diagnosis. An occlusion diagnosis unit of the diagnosis unit executes the occlusion diagnosis, based on whether or not an estimated volume of a sealed space of a fuel-vapor sealing system exceeds a volume threshold. The occlusion diagnosis determines that the vent passage is suspected of being occluded if the estimated volume is equal to or less than the volume threshold, while diagnoses that the vent passage is not occluded if the estimated volume exceeds the volume threshold. If it is determined that the vent passage is suspected of being occluded, the occlusion diagnosis unit suspends the occlusion diagnosis of the vent passage until a cumulative exhaust amount of fluid at least exceeds an exhaust amount threshold.

  • Patent number: 10481251
    Abstract: There is provided a radar device that calculates an angle of a target based on a phase difference between reception signals obtained by receiving reflected waves from the target. A transmitting unit alternately transmits first and second transmission waves having different beam patterns. A calculating unit calculates reception levels of the reception signals, and an estimate angle at which the target is estimated to exist. A first determining unit determines a degree of reliability of a level difference between the reception levels, on the basis of a comparison between the level difference with a reference value which is associated with the estimate angle in advance. A second determining unit determines whether the target exists at the estimate angle, on the basis of a determination result and the reception level based on the first transmission wave.

  • Patent number: 10477848
    Abstract: The spool brake device is equipped with a brake unit, a detector, and a controller. The controller controls the braking force by the brake unit based on the variation of the rotational speed of the spool detected by the detection unit. When the rotational speed is increasing, the controller controls the braking force by the brake unit in the regular braking mode. In the regular braking mode, the controller changes the braking force by the brake unit according to the rotational speed of the spool. In addition to it, when the rotational speed of the spool stops, the controller is to control the braking force by the brake unit in the first braking mode, during a period of predetermined time. In the first braking mode, the controller makes a braking force by the brake unit that is less than the braking force in the regular braking mode.
