  • Publication number: 20220160320
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, an X-ray variable diaphragm, an X-ray detector, and processing circuitry. The X-ray tube irradiates X-rays. The X-ray variable diaphragm limits an irradiation region of the X-rays. The X-ray detector detects the X-rays that have passed through an object. The processing circuitry controls a movement of the X-ray tube, the X-ray detector, and an aperture of the X-ray variable diaphragm such that, when the irradiation region on the X-ray detector moves within an imaging range, a movement velocity of the irradiation region relative to the imaging range is maintained constant.

  • 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: 9151691
    Abstract: Methods and apparatus for detecting machine tool window airtightness includes an airtight state detector, having a sensor detecting the pressure in a space of the window, and a judging section for determining appropriateness of the airtight state of the space based on a pressure value from the pressure sensor and outputting a judgment result. Pressure in the window space, which initially may be pressurized or pressure-reduced, is detected intermittently by the pressure sensor, and the judging section determines appropriateness of the airtight state of the window on the basis of a variation state of the detected pressure.

  • 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.

  • Patent number: 8922332
    Abstract: Electronic equipment, including a GPS dongle and a PC, compares an acquired current location position of the electronic equipment with an acquired planned installation position of a machine tool to determine whether or not the current location position is within a predetermined range from the planned installation position. Further, the electronic equipment determines, if it is determined that the current location position is within the predetermined range from the planned installation position, whether or not a predetermined condition has been satisfied. The electronic equipment also performs, if it is determined that the predetermined condition has been satisfied, information input processing on the machine tool to remove activation restriction on the machine tool. In this manner, the electronic equipment can prevent illegal removal of activation restriction on the machine tool.
