    摘要: The moving blades are configured so as to meet a condition: (L+3D)×f≧14,500 or L×(L+D)×f2≧1.55×107, where L is an effective length of the moving blade measured in inches, D is a blade root circle diameter of the moving blades measured in inches, and f is the rated operating speed of the turbine measured in Hz. The moving blades are formed of a titanium alloy. The dovetail has an Christmas-tree shape, and is a curved-axial-entry. The moving blades are configured and arranged so as to meet a condition: 3.5≦P/W≦7.0 or 0.8≦P/C≦1.0, where W is a width of a section of a tip of the moving blade measured along an axis of the rotor wheel, P is pitch of the moving blades, and C is a chord length of the tip section of the moving blade. Adjacent moving blades are connected to each other in such a manner that the adjacent moving blades being capable of relative movement while the adjacent moving blades being connected to each other.

    摘要: A memory bandwidth control device for improving efficiency of data transfer between an external device and a memory. A memory is used for temporarily storing and outputting data to be communicated with external devices being connected via input/output ports, and an I/O buffer dynamically assigns memory bandwidth to external devices requesting data transfer when receiving the data transfer requests from the external devices to the memory. When compared to assigning fixed memory bandwidth, efficiency of data transfer to the memory 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.
