  • Patent number: 10618458
    Abstract: A vehicle headlight control device is provided with: a pedestrian detection unit which detects a pedestrian; and a headlight control unit which controls an irradiation state of a headlight. When the pedestrian detection unit detects a pedestrian within an irradiation range of the headlight, the headlight control unit executes dimming control for controlling the irradiation state of the headlight so that a periphery of the pedestrian is dimmed. The pedestrian is irradiated with a part of a high beam or a low beam, or marking light emitted from a dedicated light source. A dimming region is formed around the pedestrian by the dimming control, and contrast in brightness between the pedestrian and his/her surroundings can be raised.

  • Patent number: 10520396
    Abstract: A tire uniformity testing apparatus (1) measures uniformity of a tire (T) by measuring a load generated on the tire (T) pressed against a rotating rotary drum (2). A load model used to control a pressing position of the rotary drum (2) and express a relation between the pressing position of the tire (T) against the rotary drum (2) and a tire load generated in the tire (T) is configured to successively measure the tire load, while changing the pressing position of the tire (T) against the rotary drum (2), and to estimate the tire load using the measured value of the measured tire load.

  • Patent number: 10473556
    Abstract: In a tire uniformity testing apparatus which measures uniformity of a tire by measuring a load applied to the tire pressed against a rotary drum, a load estimation model is generated which is used to control a pressing position of the rotary drum, and generates a load estimation model indicating a relation between the pressing position of the tire with respect to the rotary drum and the load applied to the tire. The load estimation model is generated by: holding the tire in which uniformity has already been measured for each characteristic value; acquiring a nominal model depending on the characteristic value of the tire; and generating based on the acquired nominal model.

  • Patent number: 7511727
    Abstract: The present invention employs novel phase control for a fixing heater, which uses first and second heaters, to reduce the generation of a higher harmonic wave current and a power line terminal noise. With four consecutive half wavelengths (two cycles) of a power supply voltage employed as a period, two half waves are used for phase control and other two half waves are made full ON or full OFF for each of the first and second heaters and, at the same time, the phase control is performed complimentarily to both the heaters. That is, for each half wave, when the power is turned on with the phase control of one heater, the other heater is made full ON or full OFF. This causes turn-on switching to occur only on at most one heater in a half wave period. As a result, as compared with usual phase control, a power-supply higher-harmonic-wave current and a power line terminal noise are reduced.

  • Patent number: 6301454
    Abstract: There are provided three periods of time immediately after an AC power-supply voltage is started to be applied to fixing heaters when the heater temperature falls below a target temperature: a first period for driving only a first heater; a second period for driving only a second heater following the first period; and a third period for driving the first and second heaters following the second period. During the first and second periods, the first and second heaters are thinning-controlled, respectively. At this time, at a cycle of 3 half-waves of the AC voltage applied to each fixing heater, a thinning frequency is changed from a large value to a smaller one. The third period includes first and second sub periods which are alternately repeated. In at least one of the first and second sub periods, the first and second heaters are thinning-controlled and the relation of the thinning controls of the two heaters is such that they are complementary to each other on the time axis.
