    摘要： In a drive system, there is provided a waste heat recovering device forming a Rankine cycle by an evaporator for heating water with waste heat of an internal combustion engine to generate high-pressure vapor, the internal combustion engine being connected to a transmission, a displacement-type expander for converting high-pressure vapor generated by the evaporator to an output with constant torque, a condenser for liquefying low-pressure vapor discharged from the expander, and a feed pump for supplying water liquefied by the condenser to the evaporator. The expander is connected to a power generator/motor via a planetary gear mechanism, and the expander is connected to an output shaft of the internal combustion engine via the planetary gear mechanism and a belt-type continuously variable transmission. A change gear ratio of the belt-type continuously variable transmission is controlled such that a rotational speed of the internal combustion engine and a rotational speed of the expander are matched with each other and are transmitted to the transmission. Hence, it is possible to effectively drive the driven portion by using the output of the expander of the waste heat recovering device.

    摘要： A heat- and abrasion-resistant aluminum alloy having a grain size of the matrix of .alpha.-aluminum in the alloy not more than 1,000 nm; a grain size of an intermetallic compounds contained in the alloy of not more than 500 nm; and 0.5 to 20% by volume of ceramic particles in the range of 1.5 to 10 .mu.m in particle size and dispersed in the alloy. By this composition, the stress concentration due to the ceramic particles is reduced. Furthermore, because the powders bind well with each other, the heat resistance and abrasion resistance are compatibly improved without decreasing toughness and ductility.

    摘要： A connecting rod as a shaft clamping member includes a rod member and cap, each of which has mating faces at circumferentially opposite ends of a semi-circular recess and which are fastened to each other by bolts by matching the opposed mating faces to each other to define a crank pin hole by the two semi-circular recesses. The rod member and the cap are forgings formed from an aluminum alloy and simultaneously produced by forging powder preforms of the rod member and cap in a cavity having the desired shape of the connecting rod. After forging, the opposed mating faces have an infinite number of recesses and projections which are formed from the flow of the material during the forging and which are in a matched and fitted relation to each other. Thus, any misalignment between and in a direction parallel to the mating faces can be prevented to avoid the generation of a situation that only the rod member receives a stress. This achieves a prolongation in the life of the connecting rod of the aluminum alloy. The composition of the most desirable aluminum alloy includes, by weight, 7% .ltoreq.Fe
