  • Patent number: 11131621
    Abstract: An analysis device includes an optical disc drive, a gate information processing unit, a detection circuit, and a gate shift processing unit. The optical disc drive rotates a specimen analysis disc and detects a measurement radial position for an optical pickup. The detection circuit generates gate signals shifted by a gate shift amount in each measurement radial position in a rotating direction of the specimen analysis disc, and generates count values of the respective gate signals. The gate shift processing unit divides a gate signal-corresponding region of the corresponding gate signal by a unit gate shift amount in the rotating direction of the specimen analysis disc to define a plurality of divided regions and sets count values of the divided regions based on the count values of the gate signals.

  • Publication number: 20210258004
    Abstract: A gate drive apparatus includes a driver, a peak voltage detector and a drive capability controller. The driver drives a gate of a first switching element as one of two switching elements respectively in an upper arm and a lower arm of a half-bridge circuit. The peak voltage detector detects a peak voltage at a second switching element in a situation where the first switching element is turned on. The drive capability controller calculates a value of drive capability when the driver turns on the first switching element, in a condition that the peak voltage at the second switching element does not exceed a tolerance value of a voltage at the second switching element according to a specification of the second switching element, and modifies the drive capability when the driver turns on the first switching element, based on a calculated result of the value of the drive capability.
