摘要： In a compressor, a yoke constituting a linear drive section together with a driver coil, through which magnetic fluxes from a permanent magnet pass, is integrated with a cylinder and a container. A piston inserted into the cylinder is supported by springs, and the other end thereof faces an operating-gas-compressing space. The linear drive section is arranged parallel to the piston in a diametrical direction thereof. This construction reduces the longitudinal dimension of a piston portion. Further, a plurality of parts is combined together in a main body block, thereby reducing the number of parts required and improving the assembly accuracy.

摘要： A pulse tube cryocooler where conditions under which a difference in refrigeration output due to an installation posture can be reduced as compared with conventional pulse tube cryocoolers and where the refrigeration efficiency of the cryocooler is improved, and the refrigeration output can be raised. The pulse tube cryocooler may have a regenerator coupled to a compressor through a heat radiation part and an internal regenerating agent, with the compressor repeatedly feeding and suctioning a working gas, a pulse tube coupled to the regenerator through a cooling part, and a buffer tank coupled to the pulse tube through a heat radiation part and an inertance tube. A ratio of a space volume of the pulse tube to a space volume of the regenerator may be between 0.75 to 1.5. When a diameter of a circle having an area equal to an inner cross section of the regenerator is made an inner diameter, a value obtained by dividing a length of the regenerator by a square of the inner diameter may be between 0.11 to 0.26. A ratio of an inner cross section of the pulse tube to an inner cross section of the regenerator may be between 0.1 and 0.35.
