摘要： A moving turbine blade apparatus has a plurality of moving blades (5) adapted to be mounted on a rotor shaft, a plurality of snubber covers (6) formed on outer ends of the moving blades (5), respectively, so as to be arranged successively in a circle having its center on the axis of the rotor shaft, and a plurality of ribs (10) projecting from outer surfaces of the snubber covers (6), respectively, so as to extend in a circle having its center on the axis of the rotor shaft. At least one of the opposite end portions of the rib (10) has a thickness measured in a direction of the axis of the rotor shaft greater than that of a middle portion of the same rib (10). Steam loss attributable to the leakage of steam through gaps around the outer ends of the moving blades (5) is reduced.

摘要： In a turbine blade, for a snapper cover provided on the top blade portion of the effective blade portion of the turbine blade and a snapper cover provided on the top blade portion of the effective blade portion of a turbine blade neighboring to the above-described turbine blade, contact surfaces composed of plural side-surfaces are formed in a crank shape, respectively. In these surfaces constituting the contact surfaces, a contact-friction surface of the snapper cover which is brought into contact with a contact-friction surface of the other snapper cover has a positive angle of inclination in the rotation direction of the effective blade portion. According to this structure, there is provided a turbine blade in which the contact surfaces of the snapper cover and the neighboring snapper cover are maintained in the contact-state during the driving of the turbine, and the same vibration mode as that in the rotational direction of the effective blade portion can be sufficiently controlled.

摘要： A memory bandwidth control device is capable of significantly improving efficiency of data transfer between an external device and a memory. This invention provides a memory 80 used for temporarily storing and outputting data to be communicated with external devices being connected via input/output ports, and an I/O buffer 2 for dynamically assigning memory bandwidth to external devices requesting data transfer when receiving the data transfer requests from the external devices to the memory 80. As compared with a case of assigning fixed memory bandwidth, efficiency of data transfer to the memory 80 can be significantly improved without wasting memory bandwidth.
