摘要： PURPOSE:To heat exchange fluids of different temperatures to each other and secure the heat exchange quantity by allowing the angles of a first fluid tube to protrude toward the angles of a second fluid tube, and allowing the troughs of the second tube to protrude toward the troughs of the first tube. CONSTITUTION:Since a first passage 41 in which one of high and low temperature fluids flows is brought into contact with a second passage 43 in which the other flows only via a first fluid tube 42, the one fluid can be heat exchanged with the other fluid. Further, since the first angles 42b of the tube 42 protrude toward the second angles 44b of a second fluid tube 44 and the second troughs of the second tube 44 protrude toward the first troughs of the first tube 42, the passage 43 becomes wavy to obtain its length, and the heat exchange quantity of the fluids of the different temperatures flowing in the passages 41, 43 is obtained.

摘要： PURPOSE:To expand the range of a strength possible to measure by providing a magnetic sensor, magnetism isolation unit with a variable shape and device to process a signal received from the magnetic sensor, and making an isolation level of the magnetic sensor to be adjustable. CONSTITUTION:Along with that an SQUID7 in a magnetism measuring apparatus is shielded from magnetic noise by a magnetism shield 9, a shielding device for a detecting coil 10 is constituted of a sliding cylinder 13 of 'Permalloy(R)', iris diaphragm 14 and iris control ring 15. The magnetic signal received from a measuring object is conducted to a signal input coil 8 through a coil 10 and outputted by passing through a high frequency amplifier 16 and an electronics device 7 for the detection. Then an opening aperture diameter of the iris 14 and a length of the cylinder 13 are adjusted in accordance with the signal strength of a magnetic signal source 18 which is arranged under the iris. The range of the strength for the object signal possible to measure can be thus expanded.

摘要： PURPOSE:To prevent an eccentric load from being exerted on the bearing of a crank shaft, by a method wherein two sets, each formed by a pair of expansion pistons and a compression piston, are provided, and each piston is coupled, in particular phase relations, to a crank shaft. CONSTITUTION:A stirling engine S is provided with two compression pistons 2 and 3 driven by a crank shaft and four expansion pistons 4-7. Four expansion cylinders 32-35 horizontally extending in a reverse direction to each other and two compression cylinders 30 and 31 extending in a vertical direction are formed in series to a housing. Connecting rods 13, 10 and 9 of the expansion pistons 4 and 5 and the compression piston 2, respectively, are coupled to a plurality of crank pins 14 and 15 mounted to a crank shaft. This constitution causes reciprocation of the expansion pistons 4 and 5 in an iso-phase and reciprocation of the compression piston 2 in a further delay phase than that in which the expansion pistons 4 and 5 is reciprocated.

SOLUTION: The GM type pulse tube refrigerating machine is constituted of at least three sets of refrigerating units 110, 120, 130, a common buffer tank 150 connected to respective refrigerating units, buffer side opening and closing valves 116, 126, 136 interposed respectively between the common buffer tank and the high-temperature ends 113H, 123H, 133H of respective pulse tubes for the refrigerating units and opening and closing valves V12, V23, V31 for communicating or intercepting the high-temperature sides of respective pulse tubes for respective refrigerating units mutually. Three sets of the refrigerating units are provided whereby the phase differences of operation among respective refrigerating units can be specified so as to be 120 deg. while a pressure difference between the high pressure opening and closing valves and the low pressure opening and closing valves can be reduced by approaching the pressure of the refrigerating units to a high pressure or a low pressure much more upon opening the high pressure opening and closing valve and the low pressure opening and closing valve.

摘要： PROBLEM TO BE SOLVED: To provide a pulse pipe refrigerator that a device is mountable from even either of the upper or lower part of the device and refrigeration capacity is equal even in a case of either of them being mounted. SOLUTION: A first room temperature end part 4a of a pulse pipe 4 is held at an under surface 1b of a room temperature plate 1. Thereby, a low temperature end part 4b having a lower temperature is positioned in a level lower than that of a room temperature end part 4a having a higher temperature and natural convention is prevented from occurring in the pulse pipe 4. When the pulse refrigerator is mounted on the device from below, a cold head is mounted on the second low temperature end part 2b side, and when the refrigerator is mounted from above, the device is mounted on the first low temperature end part 4b side. This constitution mounts the device both from above and from below and provides equivalent refrigeration efficiency even in a case of the device being mounted from either of them.
