  • Publication number: 20230119388
    Abstract: In the coil component, the external terminal and the metal magnetic powder-containing resin constituting the element body are not in direct contact with each other, and thus high ESD resistance is obtained. That is, even when a high transient voltage is applied between the pair of external terminals, insulation breakdown is less likely to occur, and an improvement in breakdown voltage with respect to the transient voltage can be realized.

  • Patent number: 11519501
    Abstract: A transmission includes a shift drum, an angular sensor, and a control unit. The control unit has reference values of the output values at a first rotation angle and a second rotation angle of the shift drum. The control unit is configured to obtain the output values at the first rotation angle and the second rotation angle as a first output value and a second output value, respectively. The control unit is configured to correct the output value output between the first rotation angle and the second rotation angle based on a difference between the first output value and the reference value at the first rotation angle and a difference between the second output value and the reference value at the second rotation angle.
