  • Patent number: 10371820
    Abstract: An observation data screening unit (103) executes least squares method positioning using, as an observation amount, n (n is an integer of 3 or larger) number of single difference amounts of an L1-wave pseudorange obtained from n pieces of observation data from n number of positioning satellites and n pieces of correction data corresponding to the n pieces of the observation data. The observation data screening unit (103) calculates a sum of squares of n residuals obtained for each positioning satellite by executing the least squares method positioning and normalizes the n residuals. The observation data screening unit (103) then evaluates the sum of squares of the residuals and the n normalized residuals.

  • Patent number: 10269613
    Abstract: A substrate conveying robot has left and right arms having a common pivot axis line, an arm drive unit for driving the left and right arms, and a control unit for controlling the arm drive unit. A pulley ratio between a turning pulley, a first pulley, a second pulley, and a third pulley is set so that a moving locus of the substrate holding members when the first link member is rotated about the pivot axis line by the first drive portion so as to extend and contract the arm in a state that the turning pulley is fixed is substantially linear. Thereby, the moving locus of the substrate holding member when extending and contracting the arm can be substantially linear.
