摘要： A propulsion apparatus for synchronizing the revolution speeds of a plurality of engines, each engine having a screw propeller shaft. A single regulator lever synchronously adjusts a revolution speed of the propeller shafts of the engines. When an output rpm of one of the engines has dropped, a control means lowers the revolution speed of the propeller shafts of the remaining engines to a revolution speed which is synchronized to the revolution speed of the propeller shaft of the engine whose rpm has dropped. Synchronization of revolution speeds of the remaining engines with the engine having reduced output rpm is terminated if the output rpm of that engine falls below a predetermined threshold.

摘要： A fuel control method which recognizes a revolution of a crankshaft based on the cylinders before the combustion cycle of a cylinder in question. When the supply of fuel by injection from an injector to a certain cylinder of the six cylinders has become impossible, then control is performed to change the number of cylinders targeted by the rotation recognition means so as to recognize the revolution of the crankshaft for all six cylinders whose combustion cycles are consecutive prior to the combustion cycle of the cylinder in question, and to stop the supply of fuel from the injectors for supplying fuel to cylinders whose combustion cycles are equally spaced from the cylinder to which the supply of fuel is not possible, so that the spacing between the combustion cycles in the cylinders whose combustion cycles come before and after and sandwich the cylinder to which the supply of fuel is not possible becomes uniform.

摘要： A fuel injection start timing is determined based on the engine revolution or the engine load, and a common rail pressure is detected simultaneous to this fuel injection start timing. The fuel injection duration is then calculated based on the detected value of the common rail pressure. By doing this, it is possible to obtain a fuel injection duration that is suited for the common rail pressure at the actual fuel injection start time, resulting in an appropriate injection amount.

摘要： A demultiplexer device is used in a wavelength-division multiplexed optical fiber communication line to achieve efficient dispersion compensation and loss compensation as well as a reduction of active devices such as optical amplifiers. The demultiplexer device has a series of couplers disposed in multi-stages from the input of the demultiplexer. Each coupler has two branches with one branch of each coupler connected to a separate optical filter and the other branches are series connected to a subsequent stage of the couplers through equalizing fibers, except for the final stage which has its second branch connected to an optical filter for the shortest wavelength transmitted. The equalizing fibers are thus serially connected between couplers and act to perform a cumulative dispersion compensation. The quantity of the equalizing fibers can thus be reduced as a whole, and as a result the attenuation amount also decreases, so that the number of optical amplifiers can be reduced.
摘要翻译：解复用器装置用于波分复用光纤通信线路中，以实现有效的色散补偿和损耗补偿以及减少诸如光放大器之类的有源器件。多路分解器装置具有从多路分解器的输入端以多级布置的一系列耦合器。每个耦合器具有两个分支，每个耦合器的一个分支连接到单独的滤光器，并且其它分支通过均衡纤维串联连接到耦合器的后续阶段，除了最后一级，其第二分支连接到滤光器对于最短的波长传输。均衡纤维因此串联连接在耦合器之间并用于执行累积色散补偿。因此，均匀纤维的量可以整体上减少，结果衰减量也减小，从而可以减少光放大器的数量。
