摘要： A linear actuator has inner yokes, outer yokes forming gaps between themselves and the inner yokes, and a movable body provided with planar magnets in the gaps. Eight pieces each of the inner yokes and the outer yokes are arranged at equal angular intervals in a circumferential direction with planar faces of each of the inner yokes and the of the outer yokes being opposed to each other. The movable body has magnet retaining portions having a substantially triangular shape and placed between adjacent inner yokes and between adjacent outer yokes. A linear actuator having high magnetism usability can be structured using magnetic parts suitable for mass production.

摘要： A Stirling engine is provided with a piston and a displacer. When the piston is made to reciprocate inside a cylinder by a linear motor, the displacer reciprocates inside a cylinder with a predetermined phase difference relative to the piston. In parts of the displacer and the cylinder that receives the displacer, the parts facing a compression space are made of metal, and the parts facing an expansion space are made of a low-thermal-conductivity material. In the metal part, the fitting accuracy is defined.

摘要： With spacers (30, 31) held between the central portion and the circumference of two plate springs (61, 61), a fixed shaft (67) erected on a fixed block (70) is inserted in a through hole (64) in the periphery of the plate spring (61) and also in the spacer (31), and nuts (68, 68) are applied for tightening from above and below (step #1). Thereby, a displacer supporting spring (6) is fixed to the fixed block (70). And the threaded portion (2b) of a rod (2a) is inserted in a through hole (63) in the center of the plate spring (61) and also in the spacer (30) from the upper surface side of the upper plate spring (61), and a nut (32) is attached to the threaded portion (2b) projecting from the lower surface of the lower plate spring (61) so as to fix the displacer (2) to the upper surface side of the upper plate spring (61) (step #2). In this state, small vibration is applied to the displacer supporting spring (6) (step #3). And the resonance frequency is detected (step #4) and on the basis of this result, the spring constant of the displacer support spring (6) (the combined spring constant of the two plate springs (61, 61)) is calculated, and then an additional weight ΔWd reaching the target resonance frequency is calculated (step #5).
