A process of producing a sintered compact comprises filling a cup with a powdered material to be sintered, putting on an opening of the cup a covering member consisting of a lid and solder so as to permit ventilation between the interior and exterior of the cup to form a cup assembly, applying heat as well as vacuum to the cup assembly to degas the powdered material, melting the solder by the continuation of heat to air-tightly seal the cup with the lid to obtain a closed cup compressible under high pressure at high temperature while maintaining the air-tight seal, and hot-pressing the closed cup to obtain a sintered compact.The covering member may include a porous lid closing the cup and a solder put on the porous lid.

A fixing structure for a generator shaft of a wind driven generator of outer rotor coreless type prevents deformation of the generator shaft even in strong wind and has less factors causing failures. In the fixing structure for a wind driven generator (1) of outer rotor coreless type, a screw thread (13) is formed on an end of a generator shaft (13) projecting from a generator body (10) of the wind driven generator (1), the generator shaft (13) projecting from the generator body (10) is fitted in a shaft support body (11) so as to be rotatably supported thereby, and a nut (62) is engaged to the screw thread (13a) of the generator shaft (13) to fasten the generator shaft (13) to fasten the generator shaft (13) to the shaft support body (11).

Each prefetch buffer has a tag register for storing a branch address and a data register for storing instruction data. Each of the prefetch buffers is assigned to either a first prefetch buffer rewritable during a normal operation period and a second prefetch buffer to be disabled for rewrite during the normal operation period. The second prefetch buffer can thus be prevented from being rewritten even if a central processor outputs branch addresses frequently. This realizes an improvement in the instruction fetch efficiency of the central processor and an improvement in the entire system performance. The fetch efficiency can be improved particularly in such systems that branch addresses occur frequently and some of them occur repeatedly.

摘要:
A disk-shaped coaxial inversion generator in which, on the basis of the driving force of a driving source utilizing a natural energy, a housing main body and a coil body housed therein are coaxially inverted in noncontact relationship by magnetic force, so that the relative velocity between a flux linkage magnet within the housing main body and a coil portion within the coil body is greater than the rotating velocity of the housing main body per se, thereby realizing a large generated power output. In the provided disk-shaped coaxial inversion generator, mechanical contact areas can be reduced, so that the mechanical loss, such as wear, can be reduced; a low-noise structure attributed to the reduction of mechanical contact areas can be realized; and the maintenance can be facilitated.
摘要:
A power-generating wind turbine has a plurality of streamline-wing-shaped blades provided every predetermined angle around a rotation shaft, and the blades have lift coefficients of 1.0 or larger. Apertures are provided within a range of 55 to 95% from a front rim for a length of a chord on a rear face being the rotation shaft side to the chord. Thus, the turbine can be activated with a gentle breeze by drag on the apertures. Since the apertures are provided at a position of 55 to 95% for the chord length distant from the front rim of the rear face of the blade, in a high wind speed region where the turbine rotates by the lift of the blades, less disturbance of the wind flow is observed on the rear faces to be resistance, and thus high rotation torque can be obtained.

An integrated circuit device having a send/receive macro for serially transferring addresses and data to or from an external device via a serial transfer bus, the integrated circuit device includes: a CPU for performing predetermined processing. The send/receive macro includes a send/receive buffer accessed by the CPU, for storing a plurality of units of data to be transmitted or received over the serial transfer bus; an acknowledge detection unit for detecting a data acknowledge signal transmitted from a receiving device in response to transmission of predetermined units of data; and a data send unit for transmitting data stored in the send/receive buffer, in response to detection of the data acknowledge signal by the acknowledge detection unit, without generating any interrupt to the CPU. And the acknowledge signal detection unit generates a data acknowledge signal non-detection interrupt to the CPU if the acknowledge detection unit does not detect a data acknowledge signal transmitted from the receiving device in response to transmission of the predetermined units of data.
