  • Patent number: 11059301
    Abstract: An inkjet printing apparatus is provided with a tank that stores ink, a print head that performs print operation by ejecting ink supplied from the tank, a circulation unit that establishes a circulating state to circulate ink in a circulation path if print operation is performed and establishes a stopped state to stop circulation of ink if print operation is terminated, and a deaeration unit that performs deaeration operation to deaerate ink inside the circulation path. The apparatus includes an estimation unit that estimates a dissolved gas amount in ink inside the circulation path based on dissolved gas amounts increased in the circulating state and in the stopped state, respectively, and a control unit that causes the deaeration unit to execute deaeration operation after completion of print operation if the dissolved gas amount estimated by the estimation unit exceeds a predetermined threshold.

  • Patent number: 10399481
    Abstract: A vehicle lamp system includes a high-beam lamp unit that can form a high-beam light-distribution pattern, a leveling mechanism that vertically adjusts an optical axis of the high-beam lamp unit, and a control unit that controls on/off of the high-beam lamp unit and controls the leveling mechanism. Upon the engine being started, the control unit controls the high-beam lamp unit to turn on for a predetermined period of time in a state in which the leveling unit adjusts the optical axis of the lamp unit to aim more vertically downward than in normal operation.

  • Patent number: 10246004
    Abstract: A vehicle headlight control apparatus controls headlights of a vehicle including LEDs. The vehicle headlight control apparatus includes: drivers and each of which gradually changes a luminance of the LEDs between a predetermined on state and a predetermined off state over a switching time period; and a lamp ECU that determines the switching time period in a changeable manner.

  • Patent number: 10059252
    Abstract: A lamp ECU acquires, from a sensor, a position of a target light source of a forward vehicle when viewed from a sensor mounting position, calculates, on a basis of an amount of position deviation between a lighting fixture mounting position and the sensor mounting position, a parallax-corrected direction of a target position, based on the acquired position of the target light source, when viewed from the lighting fixture mounting position, and outputs a light shielding range on a basis of the calculated parallax-corrected direction.

  • Patent number: 9156397
    Abstract: A lighting apparatus for a vehicle includes headlamps configured to be switchable between high beam and low beam, wherein a direction of an optical axis of each of the headlamps is variable in a substantially horizontal plane by use of a swivel actuator and a controller configured to control the headlamps, wherein if the controller detects a forward vehicle in projection areas of the headlamps, the controller temporarily switches from the high beam to the low beam, then drives the swivel actuator toward a target swivel angle according to a position of the detected forward vehicle and, after finishing driving toward the target swivel angle or during driving toward the target swivel angle, starts projection by the high beam.
