  • Patent number: 10369746
    Abstract: A three-dimensional data generation device includes a data division unit, a detection unit, an output command unit, and a data correction unit. The data division unit divides sectional shape data on one layer of a shaped object into mark data for shaping a mark for correction of sectional shape data on a different layer to be output as superposed on the one layer and post-removal data obtained by removing the mark data from the sectional shape data on the one layer. The detection unit detects an amount of misregistration of the mark output using the mark data from a position determined in advance. The output command unit commands output using the post-removal data so as to form the one layer of the shaped object together with the mark. The data correction unit corrects the sectional shape data on the different layer using the amount of misregistration of the detected mark.

  • Publication number: 20190226181
    Abstract: A hydraulic excavator (1) includes a controller (40) for generating, when the tip of a work implement (1A) is approaching a target surface (60) due to the pilot pressure output from an operating device (45a, 45b, 46a), a control signal for a boom cylinder (5) such that the tip of the work implement moves along the target surface and controlling the work implement (1A) by outputting the generated control signal to the flow control valve (15a) of the boom cylinder (5). The controller calculates the positional information of a finished shape (97) formed by the work implement, based on the topographic information input from a topographic measurement device (96) that measures the topography near the work machine and corrects the control signal based on the positional information of the finished shape such that the finished shape gets closer to the target surface.

  • Publication number: 20180172982
    Abstract: A mirror with a reflective layer formed thereon is supported within a frame-shaped support by two U-shaped arms. A plate-like arm connects fixation points (Q1, Q2), and a plate-like arm connects fixation points (Q3, Q4). A pair of piezoelectric elements (E11, E12) disposed along a longitudinal axis (L1) on an upper surface of an outside bridge of the arm, and a single piezoelectric element (E20) disposed along the longitudinal axis (L2) on the upper surface of an inside bridge. Similarly, a pair of piezoelectric elements (E31, E32) disposed on an upper surface of an outside bridge of the arm, and a single piezoelectric element (E40) disposed on the upper surface of an inside bridge. When a positive drive signal is applied to the piezoelectric elements (E11, E20, E31, E40) and a negative drive signal is applied to the piezoelectric elements (E12, E32), the mirror is displaced efficiently.
