  "textContent": "Through stroke control whereby the stroke of a piston 1 is detected and controlled to be equal to a target stroke, the piston 1 is prevented from colliding with a displacer 2, and the refrigerating performance of a Stirling refrigerator 40 is enhanced. Different target strokes corresponding to different operation conditions of the Stirling refrigerator 40 are stored in a storage portion 111 in a control box 30, so that a linear motor 13 can be driven with a target stroke that suits the current operation condition. Thus, the piston 1 is prevented from colliding with a displacer 2, and the refrigerating performance of a Stirling refrigerator 40 is further enhanced.",
