  • Patent number: 11530911
    Abstract: An optical measuring device includes: an emission device configured to emit a scanning light, of which an optical axis parallelly moves, to an object; a light receiving element configured to perform photoelectric conversion with respect to the scanning light after passing over the object; a calculation device configured to calculate, from a voltage wave obtained from time change of an electrical signal that is output by the light receiving element, a distance corresponding to a time range from a first edge with respect to a voltage value where the scanning light is not interrupted by the object and a second edge with respect to a voltage value where the scanning light is interrupted by the object, when a part of the scanning light is interrupted by the object for the time range.

  • Patent number: 9958263
    Abstract: A correction device for an optical measuring apparatus obtains correction data for each scanning position of a light beam from an optical measuring apparatus that includes a light beam scanner which scans with a light beam a measuring region where a measured object is placed, and a light receiver which receives a transmitted light beam from the measuring region. The correction device includes a translucent scale having scale marks arranged at a predetermined pitch, and a support to mount the scale in the measuring region so that an arrangement direction of the scale marks is a scanning direction of the light beam.

  • Patent number: 5357439
    Abstract: The present invention relates to a manufacturing system which accepts a custom order of product from a customer and custom manufactures a product without sacrificing manufacturing efficiency. The manufacturing system includes the featuring steps of inputting the required specification of a product, creating the product design based on the design information of the product transmitted from a designing department, status data from the production department, and the input required specification, showing the created product design to the customer, selectively indicating a product to be purchased, transmitting the specification of the selected product to the production department, and producing a product based on the selected product specification.

  • Patent number: 5197846
    Abstract: A six-degree-of-freedom articulated robot mechanism includes a three-degree-of-freedom translation unit for adjusting the position. The translation unit includes an orientation maintaining mechanism which has a rotation articulation of the direct drive type connecting a drive motor directly to an arm, and a link mechanism. A three-degree-of-freedom rotation unit for adjusting the orientation includes three rotation articulators of the direct drive type connecting a drive motor directly to a table, and the axes of the three rotation articulators intersect one another at one point.
