  • Publication number: 20220310316
    Abstract: In the multi-layer coil component, the hole portion is provided in the vicinity of the side surface of the element body, and the distance from the tip position of the external electrode to the hole portion is shorter than the distance from the tip position of the external electrode to the coil. Therefore, when a crack is generated starting from the tip position of the external electrode on the mounting surface, the crack progress toward the hole portion located at a distance closer than the coil. Therefore, in the multi-layer coil component, splitting of the coil due to the crack can be prevented.

  • Patent number: 11454674
    Abstract: If a charging quantity charged to a battery pack since switching from discharging to charging is more than or equal to a reference charging quantity, an ECU estimates the SOC from the OCV by referring to a charging OCV. If a discharging quantity discharged from the battery pack since switching from charging to discharging is more than or equal to a reference discharging quantity, the ECU estimates the SOC from the OCV by referring to a discharging OCV. If the electric quantity is less than the reference charging quantity or if the electric quantity is more than the reference discharging quantity, the ECU estimates the SOC from the OCV using a straight line for supplementing SOC-OCV characteristics in a region enclosed by the charging OCV and the discharging OCV.

  • Publication number: 20220294377
    Abstract: An estimation device includes a phase current determination unit, a time difference calculation unit, and an estimation unit. The phase current determination unit performs a determination process for determining values of phase currents based on the value of the bus current detected by a bus current detection unit and states of gate pulse signals. The time difference calculation unit calculates a difference between a detection time of the bus current used in a previous determination process and a detection time of the bus current used in a present determination process. The estimation unit estimates at least one of a position and a speed of an AC motor based on the values of the phase currents determined by the phase current determination unit and the difference calculated by the time difference calculation unit.

    Abstract: A method includes: forming a titanium nitride base film containing silicon by alternately repeating: precipitation of titanium nitride by alternately and repeatedly supplying a titanium-containing gas, and supplying a nitriding gas to a substrate on which a recess is formed; and precipitation of silicon nitride by alternately and repeatedly supplying a silicon-containing gas, and supplying a nitriding gas to the substrate; and subsequently, forming a tungsten film so as to bury tungsten in the recess in which the titanium nitride base film is formed, by alternately and repeatedly supplying a raw material gas containing a tungsten raw material and a reaction gas reacting with the raw material gas, to the substrate. A supply flow rate of the silicon-containing gas is adjusted so that a content of the silicon in the titanium nitride base film is high on an opening side rather than on an inner side of the recess.
