  • Patent number: 11884272
    Abstract: There is provided a motorcycle-drive assistance apparatus that makes rapid deceleration by an engine brake possible so that braking control unintended by a rider can be avoided. The motorcycle-drive assistance apparatus is configured in such a way that a deceleration-start inter-vehicle distance calculation unit calculates a deceleration-start inter-vehicle distance, by use of an acceleration value read from an engine-brake acceleration value storage unit, based on an own-vehicle speed calculated by an own-vehicle speed calculation unit and a road-surface gradient angle calculated by a road-surface gradient angle calculation unit and in such a way that when the inter-vehicle distance between an own vehicle and another vehicle, detected by an object detection unit, becomes smaller than the calculated deceleration-start inter-vehicle distance, deceleration of the own vehicle through the engine brake is started.

  • Patent number: 10071631
    Abstract: An automatic two-wheeled vehicle display device is such that, while warning information is being displayed in a second display region, a CPU changes a background color gradation of the second display region to a first gradation (for example, white) for a first setting period t1, gradually increases backlight luminosity to reach a maximum value (100%) in a third setting period t3 that is shorter than the first setting period t1, and maintains the backlight luminosity at the maximum value (t1=t3+t4) for a fourth setting period t4. Subsequently, the CPU changes the background color gradation of the second display region to a second gradation (for example, black) for a second setting period t2, and adjusts the backlight luminosity to a luminosity the same as that in a normal mode (for example, 20%).

  • Publication number: 20050199337
    Abstract: A continuous band-shaped film is guided to a predetermined transport path by a guide roller while separating a protective film, and a single polarizer is supplied to a space between the guide roller and a liftable joining roller disposed above the guide roller so as to face the guide roller while separating a separator. In a state where the joining roller is lifted to create the space between the rollers, the polarizer is supplied to the space between the rollers. When the tip end of the polarizer reaches a predetermined position in the created space between the upper and lower rollers, the joining roller is lowered and the polarizer supplied synchronously with transportation of the film is pressed against the film and joined.
