  • Publication number: 20190326091
    Abstract: An electromagnet control device includes a current value determining circuit configured to execute a second process for determining, based on a second function, a value of the current, in the case that the magnetic flux density is to be decreased from that in a first magnetization state, and a fourth process for expanding or reducing the second function by use of a first scaling ratio for transforming it to a fourth function, and determining, based on the fourth function obtained after above transformation, a value of the current, in the case that the magnetic flux density is to be decreased from that in a third magnetization state. The current value determining circuit is further configured to determine the first scaling ratio in such a manner that the second function fits measured data that are obtained in advance by decreasing the magnetic flux density from that in the third magnetization state.

  • Patent number: 10264658
    Abstract: A lighting device which can produce various fade operations without significantly consuming memory capacity is provided. Duty ratios for a plurality of steps are recorded in a ROM of a slave ECU. The slave ECU sets an interval time for 1 step, reads out from a map brightness of a next step at each set interval time, and outputs a pulse with the read out duty ratio to a LED. A change duty ratio, a pre-change interval time and a post-change interval time are recorded in the ROM. The slave ECU sets the interval time for 1 step to the pre-change interval time before the duty ratio of the LED reaches to the change duty ratio, and changes the setting by setting the interval time for 1 step to the post-change interval time after the duty ratio of the LED has reached to the change duty ratio.
