  • Patent number: 12682495
    Abstract: An automatic measuring system includes a measuring sensor tool that detects a surface of an object to be measured to measure a dimension or a shape of the object to be measured, a moving mechanism that relatively moves the measuring sensor tool with respect to the object to be measured, and an observation camera that images the object to be measured. A position and an orientation (posture) of a point to be measured are acquired from image data obtained by imaging the object to be measured by the observation camera, the measuring sensor tool is caused by the moving mechanism to approach the point to be measured, taking into account a position and posture offset between the observation camera and the measuring sensor tool, and a measurement value of the point to be measured is acquired by the measuring sensor tool.

  • Patent number: 12681029
    Abstract: There is provided an automatic measuring system that can automate measurement and a control method for automatic measurement. An automatic measuring system includes a measuring sensor tool that detects a surface of an object to be measured with a probe to measure a dimension or a shape of the object to be measured, and a multi-axis moving mechanism that relatively moves the measuring sensor tool with respect to the object to be measured. The measuring sensor tool includes a cover part to protect the probe. In an approaching step in which the moving mechanism causes the measuring sensor tool to approach a point to be measured of the object to be measured, the cover part accommodates the probe inside the cover part. After the approaching step is completed, the probe is exposed from the cover part to detect the surface of the object to be measured.

  • Publication number: 20260027751
    Abstract: A method for manufacturing a master mold for imprinting, with which structures formed in a desired forward taper can be formed on a base material. This method comprises a coating step in which a resist having a predetermined film thickness is coated on a base material, an exposure step in which the resist coated on the base material is exposed through a mas, and a development step in which the exposed resist is developed, the exposure step involving setting the exposure amount to be equal to or less than twice the minimum exposure amount (Df) at which the resist coated on the base material undergoes solarization across the entire thickness of the resist, and exposing predetermined portions of the resist, so that the side surface shape of the structure constituted of the resist formed by development in the development step is a forward taper.

  • Patent number: 11336107
    Abstract: [Object] To achieve both prevention of overcharging of the battery and convenience of the user. [Solution] An information processing device includes: a charged capacity detection unit configured to detect a charged capacity of a battery; a charging control unit configured to control a charging circuit; and a specification unit configured to specify when discharge of the battery starts. The charging control unit performs charging suppression control on the charging circuit such that the battery is charged to a preparatorily charged capacity that is lower than a fully charged capacity of the battery, on the basis of the charged capacity detected by the charged capacity detection unit, the charging of the battery stops when the charged capacity of the battery reaches the preparatorily charged capacity, and the charging of the battery restarts from the preparatorily charged capacity before discharge of the battery starts.
