  • Patent number: 10974361
    Abstract: A machine tool includes a mounting table, a tool, a shade detector, and a tool controller. A workpiece is placed on the mounting table. The tool includes a tip. The shade detector is fixed on the mounting table, provides an optical path of a laser light, and detects a shade state of the laser light. The tool controller is connected to the mounting table via a supporting structure and controls an orientation and a position of the tool. A reference point associated with the tool is provided to the tool controller. The tool controller corrects a position of the tip based on a difference between a position obtained by calculation of the reference point in the case where the tip is matched with a measurement position P of a laser light and a position of the reference point when the tip portion is actually matched with a measurement position while keeping the orientation of a tool.

  • Publication number: 20210014956
    Abstract: An X-ray generator includes an X-ray tube, a blower fan having a motor and configured to provide the X-ray tube with air, a motor control unit configured to control a rotation speed of the motor, and a casing to which the X-ray tube and the blower fan are attached. The motor control unit shifts the rotation speed of the motor from a resonance frequency of a structure including the X-ray tube and the casing. According to this configuration, a resonance phenomenon caused by vibration generated by the motor is avoided. Therefore, influences of vibration on the X-ray tube are reduced. As a result, the X-ray generator can be operated in a highly stable manner.
