An arrayed waveguide grating includes: at least one input waveguide; an input slab waveguide connected to the input waveguide; a plurality of output waveguides; an output slab waveguide connected to the output waveguides; and an arrayed waveguide. The arrayed waveguide includes: M channel waveguides connected between the input slab waveguide and the output slab waveguide; and a phase correcting portion configured to provide a predetermined phase to at least a part of the M channel waveguides by a form of the at least the part of the M channel waveguides being changed.

The present invention is to provide a safe antidiarrheal agent and a method for suppressing diarrhea by which an efficient antidiarrheal effect is achieved without using antibiotics or synthetic antibacterial agents that have been conventionally used against infections in livestock and poultry. Antibiotic-resistant pathogenic infections an also invented aid treated by the present invention. The antidiarrheal agent for livestock and poultry comprising heat-killed bacteria of Enterococcus faecalis EC-12 (FERM ABP-10284) or a treated product thereof as an active ingredient is orally administered to livestock and poultry, particularly to breast-feeding sows and piglets around the weaning period.

The dynamic gain equalizer for flattening a gain profile of an optical amplifier includes: an optical waveguide circuit having multistage optical couplers, demultiplexing and multiplexing, each formed by connecting optical couplers arranged at a plurality of stages; and optical connecting circuits including optical phase shifters each capable of changing a phase of propagating light and optical delay lines each for adding a predetermined delay time to the propagating light, said dynamic gain equalizer in which at least one of the optical couplers in the two multistage optical couplers are provided with variable optical amplitude means, respectively, and each of the multistage optical couplers are formed asymmetrically with respect to an extension of a line which connects a center arranged position of optical outputting ends of the demultiplexing multistage optical coupler with a center arranged position of optical inputting ends of the multiplexing multistage optical coupler.
摘要:
The present invention is to provide an agent for preventing and treating drug-resistant bacterial infection for livestock/fowls or fish and shellfish, using particular microbial agents as active components, without using synthetic antibacterial substances or antibiotics, and a method for preventing and treating its infection. By using lactic acid bacteria, their dead bacteria or treated substances thereof, or Mygasphaera elsdenii as active components, for an agent for preventing and treating drug-resistant bacterial infection for livestock/fowls or fish and shellfish carrying or being infected by drug-resistant bacteria such as Vancomycin, particularly by using Enterococcus faecalis, Enterococcus faecium as lactic acid bacteria, the above mentioned object was resolved.
