摘要： An optical repeating system includes an optical transmitter and an optical amplifying repeater. The optical transmitter transmits a supervisory command and a control command to the optical amplifying repeater as a first sub-signal. The supervisory command is a command to supervise internal circuits of the optical amplifying repeater, and the control command is a command to control the optical amplifying repeater. The optical amplifying repeater includes multiple sub-modules each for amplifying and repeating main signals on multiple sets of optical transmission lines. When receiving the supervisory command via the optical transmission line, each sub-module transmits a supervisory signal indicating the supervisory result associated with the supervisory command to an optical receiver as a second sub-signal. In addition, when receiving a predetermined control command via the optical transmission line, each sub-module initializes another sub-module of the multiple sub-modules in response to the predetermined control command. The optical amplifying repeater can restart its control program even when it has fallen into a state where it is difficult to continue to execute the normal operation in accordance with the control program because of some exception or the like.

摘要： The present invention regenerates optical signals in an intact optical state according to a low-speed optical clock. In one embodiment, an optical splitter applies a portion of optical pulse signals to a clock recovery circuit and the rest to an optical splitter. The optical splitter applies half of the input signal to an optical regenerator and the rest to another optical regenerator. The clock recovery circuit regenerates an electric clock signal with half the frequency of the input optical pulse and applies the clock to an optical clock pulse generator. The optical clock pulse generator generates an optical clock signal with half the frequency of the input optical pulse whose phase matches with that of the optical signal at the optical regenerator. An optical regenerator regenerates the optical signal from the optical splitter in an intact optical state. A polarization combiner combine the optical signals from the optical regenerators in mutually orthogonal polarization.

摘要： A piston slidably fitted in a cylinder is connected to an auxiliary piston slidably fitted in an auxiliary cylinder coaxial with the cylinder through a first connecting rod. The left and right crankshaft halves are disposed outside of a piston sliding range of the cylinder with respect to the radial direction thereof. The increase of the volume of a combustion chamber corresponding to the increase of the crank angle with reference to top dead center of the piston is suppressed, and it is therefore possible to enhance the equal volume degree at the time of combustion of a mixture gas and to enhance thermal efficiency. This arrangement also enhances thermal efficiency, and simplifies the structures of intake systems and valve mechanisms when employed in horizontally opposed type internal combustion engine.

摘要： To increase thermal efficiency by increasing the degree of constant volume of a fuel-air mixture at the time of combustion in an internal combustion engine. In an internal combustion engine, a piston slidably fitted in a cylinder is connected to a crankshaft via a connecting rod, and a cylinder head in which a combustion chamber is defined is disposed between the piston and the crankshaft. As compared with a background art internal combustion engine in which a combustion chamber is disposed opposite to a crankshaft with a piston located therebetween, a ratio of an increased amount of the volume of the combustion chamber to an increased amount of a crank angle of the piston from the top dead center position can be suppressed at a small value.

摘要： An object of this invention is to improve transmission characteristics in WDM transmission. An optical transmitter (10) wavelength-multiplexes signal lights of wavelengths &lgr;1 through &lgr;n and outputs them onto an optical transmission line (12). Optical powers of the signal lights of the respective wavelength &lgr;1 through &lgr;n are identical or become smaller proportional to the wavelength. One repeater span of the optical transmission line (12) is composed of an optical fibers (20, 22) and an optical amplifier (24), and a gain equalizer (26) is dispersed every several repeater spans. The optical amplifier (24) in the repeater span amplifies each signal light so that optical power of a signal on the shorter wavelength side becomes smaller than that of a signal on the longer wavelength side. The gain equalizer (26) equalizes optical powers of the respective signal lights.

摘要： To realize an optical demultiplexer with a constant chromatic dispersion value, an optical signal of wavelength (&lgr;1) enters a port (A) of an optical circulator (10), and an optical signal of wavelength (&lgr;2) enters a port (A) of an optical circulator (12). A port (B) of the optical circulator (10) connects to a port (X0) of an interleaved optical filter (14), and a port (B) of the optical circulator (12) connects to a port (X1) of the optical filter (14). A port (Y0) of the optical filter (14) connects to a port (Y1) of the optical filter (14) through an optical isolator (16). The optical isolator (16) allows the optical propagation from the port (Y0) to the port (Y1) of the optical filter (14) and refuses the optical propagation from the port (Y1) to the port (Y0). An optical coupler (18) combines the input lights of the input ports (X0 and X1) from ports (C) of the optical circulators (10 and 12) and outputs from the output port (Y0). The optical filter (14) transmits wavelength (&lgr;1) in the straight propagation between the ports (X0, Y0) and between the ports (X1, Y1) and transmits wavelength (&lgr;2) in the cross propagation between the ports (X0, Y1) and between the ports (X1, Y0).
