Patent CA-2228122-A1 (CA)
Inventor: YADLOWSKY MICHAEL J
IPC: H04B10/17
Filed: 1998-01-28
Abstract: The variables and parameters previously understood to affect the gain spectrum of an optical amplifier 13 were: (1) the wavelengths to be amplified; (2) the input power levels at those wavelengths; (3) the characteristics of the amplifying medium 20; (4) the insertion loss spectra of the amplifier's components, including any filter(s) used for gain flattening; (5) the pump band chosen to pump the amplifying medium 20; and (6) the total amount of pump power supplied in the chosen pump band. An additional fundamental variable has been identified which can be used to control the gain spectrum of an optical amplifier 13, namely, the center wavelength of the spectrum of the pump's output power within the chosen pump band. Methods and apparatus for using this variable for this purpose are disclosed. For example a, transmission system is disclosed having a transmitter 11 and a receiver 10 connected by an optical fiber 12. A plurality of optical amplifiers 13 are located along the optical fiber 12 to amplify signal channels between the transmitter and receiver. Each of the amplifiers has a pump light source 21, the wavelength of which is such that contributions to differential gain due to pump light wavelength related effects is substantially reduced.     Also disclosed is a WDM transmission system having a transmission path including a concatenation of laser diode pumped optical amplifiers 13 wherein the gain spectrum of an amplifier is controlled at least in part by a feedback loop regulating the temperature of its laser diode pump 21. The feedback loop may for instance derive its control signal from a measure of the drive current applied to the pump, of the emission wavelength of the pump, or of the disparity between the power output from the amplifier in one of the multiplexed signal channels and that from at least one other of the channels.

IPC: F02B31/00
Filed: 1998-07-30
Abstract: The object of the present invention is to concentrate the intake air flowing into a combustion chamber of an internal combustion engine near the ignition point of a spark plug, and to form a strong swirl effect in this area.   A projection 16 is formed on an end surface 5a of a piston 5. Projection 16 is positioned near an intake port disposed on one side of the upper surface of a combustion chamber. A cavity 17 is formed at a position closer to an exhaust port than projection 16. An ignition point of a spark plug is disposed above cavity 17. The intake port points toward the outer perimeter of the combustion chamber. The portion of projection 16 on piston end surface 5a that lies in the direction of the intake port is cut away. An intake flow passage 19 is formed on end surface 5a of piston 5, extending from a cut-away section 18 toward the exhaust port via the outer perimeter of piston end surface 5a. The end of intake flow passage 19 toward the exhaust port forms a cavity entry 20 through which intake air flows into the cavity 17.  The intake air entering the combustion chamber from the intake port goes through cut-away section 18 of projection 16, through the outer perimeter portion of piston end surface 5a, and into cavity 17 from entry 20 toward the exhaust port. A  swirling effect is formed in cavity 17.
