  • Patent number: 10693362
    Abstract: A switching power supply includes an insulated transformer, a full-bridge circuit which converts input DC power into AC power and outputs the AC power to a primary-side coil, an output circuit which converts AC power input from secondary-side coils into DC power and outputs the DC power, and a control circuit which controls the full-bridge circuit by using a phase shift method based on voltage output by the output circuit. When a measured value of the amount of phase shift determined from at least one of the voltage and current output by the output circuit is smaller than a theoretical value of the amount of phase shift corresponding to the switching power supply operating in a continuous current mode, the control circuit prolongs dead time used in the full-bridge circuit in accordance with the difference between the measured value and the theoretical value.

  • Patent number: 10636620
    Abstract: By switching between a plurality of image transfer units based on a state of a stage and using the switched image transfer unit, traceability of stage movement and tolerance to communication failure can be improved. A first image transfer protocol is a protocol of which reliability is higher than reliability of a second image transfer protocol, and a switch unit may select a first image transfer unit in a case where it is determined that a state of a stage is a state in which the stage is stopping. A second image transfer unit is a protocol of which a transfer speed is higher than a transfer speed of the first image transfer protocol, and the switch unit may select the second image transfer unit in a case where it is determined that the state of the stage is a state in which the stage is moving.

  • Patent number: 8957959
    Abstract: A charged particle microscope corrects distortion in an image caused by effects of drift in the sampling stage by measuring the correction reference image in a shorter time than the observation image, making corrections by comparing the shape of the observation image with the shape of the correction reference image, and reducing distortion in the observation images. The reference image for distortion correction is measured at the same position and magnification as when acquiring images for observation. In order to reduce effects from drift, the reference image is at this time measured within a shorter time than the essential observation image. The shape of the observation image is corrected by comparing the shapes of the reference image and observation image, and correcting the shape of the observation image to match the reference image.
