摘要： A compressor for a refrigeration machine is provided without any problems of reduction in the life of a thrust bearing structure even when a substitutive coolant not containing any chlorine is used. In the compressor for a refrigeration machine having a thrust bearing made of steel for supporting a thrust load applied to a drive shaft, a thrust bearing surface made of a material different from that of the drive shaft is formed in the thrust bearing by means of a surface treatment. Alternatively a washer defining the thrust bearing surface may be surface treated to provide a material different from that of the drive shaft. The washer may also be made of a material different from that of the drive shaft. According to the the present invention, even when a boundary lubricating state is produced between the drive shaft and the thrust bearing surface sticking is prevented. As a result, the life of the thrust bearing structure of the drive shaft can be made longer and a problem of reduction in the life of the thrust bearing structure can be avoided even when a substitutive coolant not containing any chlorine is utilized.
摘要翻译：提供一种用于制冷机的压缩机，即使使用不含氯的替代冷却剂，也不会产生推力轴承结构的寿命降低的问题。在具有用于支撑施加到驱动轴上的推力负载的由钢构成的推力轴承的制冷机的压缩机中，由推力轴承形成的与驱动轴不同的推力轴承表面形成在推力轴承中表面处理。或者，限定止推轴承表面的垫圈可以被表面处理以提供与驱动轴不同的材料。垫圈也可以由与驱动轴不同的材料制成。根据本发明，即使在驱动轴与推力轴承面之间产生边界润滑状态，也能够防止粘着。结果，即使使用不含氯的替代冷却剂，驱动轴的推力轴承结构的寿命也可以更长，并且即使使用不含氯的替代冷却剂，也能够避免推力轴承结构的使用寿命的问题。

摘要： A closed rotary compressor includes a generally cylindrical sealed vessel having an oil sump defined therein for accommodating a quantity of lubricating oil, a drive unit housed within the sealed vessel and having a drive motor and a shaft driven by the drive motor, and a compressor mechanism housed within the sealed vessel. The compressor mechanism is provided with at least one set of compression elements. This set of compression elements is made up of a cylinder having a compression compartment and a refrigerant intake port both defined therein in communication with each other, first and second bearings secured to the lower and upper end surfaces of the cylinder, respectively, for rotatably supporting the shaft, a crank provided on the shaft for rotation together therewith, a ring-shaped roller encircling the crank and capable of undergoing a planetary motion in contact with the crank during rotation of the crank, and a radial vane slidably accommodated in the cylinder for reciprocating movement in a direction radially of the cylinder. The radial vane has a radial inner end held in sliding contact with an outer peripheral surface of the ring-shaped roller, to thereby divide the compression compartment into a suction chamber and a compression chamber. An oil passage is provided in the compressor mechanism to place the oil sump in communication with the refrigerant intake port. The oil passage has a throttled portion at a location adjacent to the refrigerant intake port.

摘要： In a hermetic type compressor, a sliding part (11) between a main shaft (4) and a lower end plate (8) is large in wear, and it is not allowed to operate stably for a long period. By communicating between the sliding part (11) and an oil feed pump (9) through an oil feed port (12), refrigerating machine oil (2) is supplied by force into the sliding part (11), and hence the lubrication is improved and the reliability is enhanced. In particular, it is preferably applied to the hermetic type compressor using HFC derivative refrigerants.

摘要： The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semiconductor or an antiferromagnetic material against the magnetic layers, and the magnetoresistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a current flows in the intermediate layer. The film surfaces of all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.

摘要： DC bias currents are applied to a conducting wire of a thin film magnetic head to be inspected. When the DC bias currents (I.sub.0, I.sub.1, I.sub.2) are supplied to the conducting wire, the impedances (Z.sub.0, Z.sub.1, Z.sub.2) corresponding to the DC bias currents are measured. When a ratio (.vertline.Z.sub.1 -Z.sub.0 .vertline./.vertline.Z.sub.2 -Z.sub.0 .vertline.) corresponding to an overwrite characteristic (OW) reaches to a predetermined value by lapping tip portions of an upper magnetic layer and a lower magnetic layer of the magnetic head, the lapping process of the magnetic head is finished.
