  • Patent number: 11798780
    Abstract: The scanning charged particle beam microscope according to the present application is characterized in that, in acquiring an image of the FOV (field of view), interspaced beam irradiation points are set, and then, a deflector is controlled so that a charged particle beam scan is performed faster when the charged particle beam irradiates a position on the sample between each of the irradiation points than when the charged particle beam irradiates a position on the sample corresponding to each of the irradiation points (a position on the sample corresponding to each pixel detecting a signal). This allows the effects from a micro-domain electrification occurring within the FOV to be mitigated or controlled.

  • Patent number: 11707678
    Abstract: A non-limiting example game system includes a processor incorporated in a main body apparatus, and the processor makes a player character hit a ball according to an operation of a player. A movement gauge is displayed in a parameter determination screen, and the movement gauge includes a belt-shaped basic area and a risk area outside the basic area. A first index image is moved inside the basic area, and a hitting power is determined at a position that the movement is stopped by an operation of the player. The hitting power affects a flight distance of a ball. After the hitting power is determined, a position of a deviation indication image displayed along the first index image is determined at random. A deviation amount is made larger as the deviation indication image is moved away from the center of the first index image. The risk area is enlarged toward an upper end of the movement gauge. That is, if the flight distance of the ball is made longer, the deviation amount may become larger.
