  • Patent number: 7002315
    Abstract: A servo control device comprises a current supply unit for supplying a drive unit with a drive current for driving a target to be controlled, a first detector for detecting at least the drive current value, and a logical arithmetic section. The logical arithmetic section introduces a current command determining the drive current for controlling the drive speed of the drive unit to move the target to a predetermined position, and introduces the drive current value fed back from the first detector. The logical arithmetic section outputs the current command to the current supply unit after converting the current command by a digital logic process on the basis of the drive current value by using a custom LSI.

  • Publication number: 20050051840
    Abstract: A high withstand-voltage semiconductor device has a gate electrode in a semiconductor layer of one conductivity type, a drain diffusion layer and a source diffusion layer, a thick gate insulating layer between the drain diffusion layer and the gate electrode, and a low-concentration offset diffusion layer of the opposite conductivity type in a region including the drain diffusion layer. A buried layer of the one conductivity type, which has a higher concentration than the semiconductor layer, is provided directly under the gate electrode at approximately the same depth as the depth of the offset diffusion layer. The buried layer disperses field concentration at the drain junction to thereby ensure a higher withstand voltage.
