摘要： A three-dimensional-measuring-apparatus inspection gauge includes a plurality of targets to be measured with which a tip of a probe of a three-dimensional measuring apparatus comes into contact; and a frame member that supports the plurality of targets. The plurality of targets are arranged in positions corresponding to each vertex of a triangular prism.

摘要： A workpiece holder is configured to hold a workpiece and is utilized in a metrology system which includes a sensing configuration for obtaining 3-dimensional surface data for the workpiece. The workpiece holder includes at least three reference features (e.g., spherical reference features extending from sides) that are configured to be sensed by the sensing configuration when the workpiece holder is in different orientations (e.g., as rotated 180 degrees between first and second orientations for presenting front and back sides of the workpiece towards the sensing configuration). A determination of 3-dimensional positions of the reference features for each orientation enables a combining (e.g., in a common coordinate system) of 3-dimensional surface data that is acquired for the workpiece in each orientation. Interchangeable workpiece holding portions may be provided that fit within the workpiece holder for holding workpieces with different characteristics (e.g., having different sizes and/or shapes).

摘要： There is provided a measuring tool attachment cover that combines ease of holding and performance (for example, heat insulation). An attachment cover includes a front face layer 110, a rear face layer 120 and an intermediate layer 130. The front face layer 110 and the rear face layer 120 are compact layers with low porosity, and the intermediate layer 130 is a hollow structural layer with higher porosity than the front face layer 110 and the rear face layer 120. The hollow structural layer includes two or more layers with different porosity, and a layer of the two or more layers closer to the front face has higher porosity than a layer closer to the rear face. A direction from the rear face layer 120 to the front face layer 110 is a thickness direction, and a direction orthogonal to the thickness direction is a width direction. The hollow structural layer has elastic modulus distribution in the width direction, and an elastic modulus of a certain area is different from an elastic modulus of an area surrounding the certain area.

摘要： A caliper measurement force detecting device includes a fixed unit that is securely attached to a slider so as not to displace relative to the slider; a movable unit that is provided to allow a slight displacement relative to the fixed unit along a direction parallel to a displacement direction of the slider; and pressure detectors that are arranged between the fixed unit and the movable unit and are provided so as to detect pressure applied in the direction parallel to the displacement direction of the slider. The movable unit includes an alternative finger hook that is arranged near a finger hook of the slider and serves as an operator that pushes and pulls the slider instead of the finger hook of the slider.

摘要： An illuminator includes: a light emitter including a light-emitting diode; a temperature sensor configured to detect a current temperature of the light emitter; and an illumination controller configured to adjust a drive voltage being supplied to the light emitter in accordance with the current temperature. The illumination controller includes a reference temperature storage in which a reference temperature is stored in advance and is configured to adjust the drive voltage by detecting the current temperature from the temperature sensor on a constant time cycle and comparing the current temperature with the reference temperature.
