    • A multiple valve engine for a watercraft includes an improved construction that contributes in balancing the weight of the engine between the port and starboard sides of the watercraft hull. The hull defines a center plane extending generally vertically from bow to stern. The engine includes a cylinder body defining at least one cylinder bore. An axis of the cylinder bore is inclined from the center plane. At least two intake passages communicate with a combustion chamber. Intake valves are arranged to selectively connect and disconnect the intake passages with the combustion chamber. At least one exhaust passage communicates with the combustion chamber. In one mode of the invention, the number of exhaust passages in the engine is less than the number of intake passages. At least one exhaust valve is arranged to selectively connect and disconnect the exhaust passage with the combustion chamber. The intake valves lie closer to the center plane than does the exhaust valve(s).
    • 用于船舶的多阀引擎包括改进的结构,其有助于平衡船舶船体的端口和右舷之间的发动机的重量。 船体定义了一个从弓到船尾垂直延伸的中心平面。 发动机包括限定至少一个气缸孔的气缸体。 气缸孔的轴线从中心平面倾斜。 至少两个进气通道与燃烧室连通。 进气阀布置成选择性地连接和断开具有燃烧室的进气通道。 至少一个排气通道与燃烧室连通。 在本发明的一个模式中,发动机中排气通道的数量小于进气通道的数量。 至少一个排气阀布置成选择性地连接和断开与燃烧室的排气通道。 进气门比排气阀更靠近中心平面。

    • An optical transmission system is provided in which a plurality of Raman amplifiers are combined so that the wavelength band of a first Raman amplifier in the form of an upward convex curve including the maximum gain value and the wavelength band of a second Raman amplifier in the form of a downward convex curve including the minimum gain value overlap with each other, and that the wavelength band of the first Raman amplifier in the form of a downward convex curve including the minimum gain value and the wavelength band of the second Raman amplifier in the form of an upward convex curve including the maximum gain value overlap with each other. This arrangement also applies to cases where three or more amplifiers are used. Due to this arrangement, an optical transmission system is realized in which it is possible to attain a reduction in Raman gain flatness without using any means such as an equalizer.
    • 提供一种光传输系统,其中组合多个拉曼放大器,使得以包括最大增益值和第二拉曼放大器的波长带的向上凸曲线的形式的第一拉曼放大器的波长带的形式 包括最小增益值的向下凸曲线彼此重叠,并且以包括第二拉曼放大器的最小增益值和第二拉曼放大器的波长带的向下凸曲线的形式的第一拉曼放大器的波长带的形式 包括最大增益值的向上凸曲线彼此重叠。 这种布置也适用于使用三个或更多放大器的情况。 由于这种布置,实现了一种光传输系统,其中可以在不使用诸如均衡器的任何装置的情况下实现拉曼增益平坦度的降低。
