摘要： PROBLEM TO BE SOLVED: To provide a capacity control mechanism capable of shortening a time taken until a discharge capacity is increased after the start of a variable displacement compressor and ensuring a refrigerant discharge flow rate suitable for lubrication and capacity control. SOLUTION: A first control valve 32, a second control valve 46, a third control valve 73, and a fourth control valve 47 are assembled into a rear housing 13. A valve element 49 of the second control valve 46 partitions a back pressure chamber 52 in a valve housing 48. When the first control valve 32 is in an opened state, the pressure of a discharge chamber 132 spreads to the back pressure chamber 52 and the second control valve 46 is closed. When the first control valve 32 is closed, the second control valve 46 is opened. The third control valve 73 is shifted to an opened state in a process in which a difference between the pressure of a control pressure chamber 121 and the pressure of a suction chamber 131 is increased from a closed state. The fourth control valve 47 is shifted to an opened state from a closed state in a process in which a difference in pressure is further increased. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive steel shoe securing the excellent slidability characteristic by limiting the heat treatment applied to the shoe, and to manufacture the steel shoe easily and inexpensively. SOLUTION: The shoe is molded nearly in the shape of a finished product in the molding process, and ground to adjust the shape and dimension. Then, the shoe is treated with the nitriding process without being subjected to hardening. If the nitriding process is performed after hardening, the shoe may be deformed in the nitriding process. As hardening is not performed, the deformation of the shoe is prevented and the grinding process after the nitriding process can be omitted. Further, since other heat treatments will not be performed after the molding, the shoe can be manufactured speedily. In addition, by finishing and molding the shoe to be shaped as the finished product in the molding process, the grinding process can also be omitted, so that the shoe can be manufactured more inexpensively and speedily.
摘要翻译：要解决的问题：提供一种便宜的钢鞋，其通过限制施加到鞋的热处理来确保优异的滑动性，并且容易且廉价地制造钢靴。解决方案：鞋子在成型过程中几乎成型成一个成品的形状，并研磨以调整形状和尺寸。然后，用氮化处理对鞋进行处理而不进行硬化。如果在硬化后进行氮化处理，则在渗氮过程中，鞋可能会变形。当不进行硬化时，防止鞋的变形，并且可以省略在氮化处理之后的磨削过程。此外，由于在成型后不进行其他热处理，所以可以快速制造鞋。此外，通过在成型工序中精加工成型成为成品的鞋，也可以省略磨削加工，可以更廉价，更快速地制造鞋。
