    摘要: A hull configuration for a small personal watercraft having a hull configuration that permits the watercraft to be ridden and leaned like a motorcycle and which will preclude excess spray from passing upward beyond the gunnel. A ventilating cover assembly is provided for accessing the engine compartment and a forwardly positioned fuel tank is incorporated having a filler neck that is accessible at one side of the deck.

    摘要: In an address translation device having a main address translation unit (20) with a main access time that translates an input virtual address into a main real address, a subsidiary address translation unit (30) is connected to the main address translation unit (20). The subsidiary address translation unit (30) has a subsidiary access time shorter than the main access time and translates the input virtual address into a subsidiary real address. Connected to the main address translation unit (20) and the subsidiary address translation unit (30), an output address production unit (40) selectively produces one of the main real address and the subsidiary real address as an output real address. The subsidiary address translation unit (30) has an access/real address register (31) holding a buffer access address of the input virtual address and the main real address as a held access address and a held real address, respectively.

    摘要: The wear-resistant compound roll is constituted by a shell portion made of an iron-base alloy having the composition consisting essentially of 1.0-3.5 weight % of C, 3.0 weight % or less of Si, 1.5 weight % or less of Mn, 2-10 weight % of Cr, 9 weight % or less of Mo, 20 weight % or less of W, 2-15 weight % of V, 0.08 weight % or less of P, 0.06 weight % or less of S, 300 ppm or less of B, the balance being substantially Fe and inevitable impurities, and a shaft portion made of steel. The iron-base alloy of the shell portion has a structure containing by an area ratio 5-30 % of granular carbides and 5 % or less of non-granular carbides, an alloy matrix of the shell portion having a Vickers hardness (Hv) of 550 or more. This compound roll has excellent wear resistance and resistance to surface roughening.
