Abstract: A shot treatment apparatus ejects shot material from a nozzle towards a workpiece, and has the nozzle; a nozzle moving mechanism; and a three-dimensional information obtaining sensor; a pattern storage portion storing a nozzle reference operation pattern when the workpiece is installed at a reference position and a reference pose within the treatment compartment; a model data storage portion storing workpiece three-dimensional model data; a position/pose displacement calculating portion comparing the position and pose information and reference position and pose data when the three-dimensional model data is at the reference position in the reference pose to calculate a displacement in a position and pose of the workpiece from the reference position and pose data; and a nozzle movement control portion correcting the pattern based on the displacement in the position and pose, and controlling the nozzle moving mechanism to move the nozzle based on the corrected pattern.

Abstract: A memory system includes a nonvolatile semiconductor memory and a controller. The controller controls the nonvolatile semiconductor memory. The controller selects whether to use the nonvolatile semiconductor memory in a first read mode or in a second read mode having shorter access intervals than the first read mode.
