    • An expansion unit (4) for converting an expansion energy of pressure-increased steam into a rotation energy of an output shaft, wherein a cover member (26) is provided on the casing outer surface of the expansion unit (4). The cover member (26) has a function of sealing the end section of an output shaft (23) protruding beyond the casing outer surface against the outside and a function of recovering steam led out from the casing and has its pressured reduced after the conversion. The end section of the output shaft (23) provided inside the cover member (26) and a driven-side transmission shaft (119) disposed outside the cover member (26) are coupled with each other via a magnet type shaft coupling (120) so as to be able to transmit power, whereby the output shaft (23) and the driven-side transmission shaft (119) can be coupled without steam in the expansion unit leaking outside.

    • A Rankine cycle system is provided in which, with regard to a given relationship between the pressure (Pevp) and the temperature (Tevp) of a vapor that is taken into an expander (4) that includes a cylinder chamber in a first stage and a vane chamber in a second stage, the chambers being disposed in line, the expansion ratio of the vapor that the expander (4) takes in and discharges is set at a predetermined expansion ratio (ε) according to the given relationship so that the pressure (Pexp2) and the temperature (Texp2) of the vapor that is discharged from the expander (4) coincide with target values, thereby making the expander (4) and the condenser (5) exhibit maximum performance. Since the vapor within the cylinder chamber in the first stage is in a superheated vapor region and contains no water, the phenomenon of water hammer will not be caused in the cylinder chamber. Furthermore, since the vapor at the exit of the vane chamber is in a saturated vapor region and contains water, the vane chamber can be lubricated and sealed by means of the water.

    • For grinding one of axially spaced journal sections of a workpiece each having a cylindrical surface and a pair of shoulder surfaces extending radially outward from the opposite end portions of the cylindrical surface, a rotating grinding wheel is advanced to grind the shoulder surfaces of one journal section and then to grind the cylindrical surface of the one journal section. At the end of the cylindrical surface grinding, the grinding wheel is retracted by a fixed distance at a slow feed rate and is further retracted at a rapid feed rate. A rest shoe provided on the side opposite to the grinding wheel with the workpiece therebetween is advanced to an advanced position where the rest shoe contacts with another journal section axially spaced from the one journal section to decrease the flection of the workpiece caused by grinding resistance and is retracted away from said another journal section when the fixed-distance retraction of the grinding wheel is completed.
