    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.

    摘要: A blade for an axial fluid machine comprises an effective blade portion having a root portion and a tip portion and projecting blade portions. The projecting blade portions are defined by axis reference lines extending to an upstream side with respect to a fluid flow from at least one of the root portion and the tip portion of the effective blade portion and by axes obliquely extending from ends of the axis reference lines toward a leading edge of the effective blade portion. The projecting blade portions are formed continuously to and integrally with the leading edge of the effective blade portion so that the effective blade portion and the projecting blade portions have substantially the same maximum blade thickness.
