摘要： A heat-pipe type solar collector comprises as its principal portion a plurality of heat pipes arranged in parallel with each other and having vaporizing portions and condensing portions, and a plurality of heat collector plates traversing the heat pipes and arranged in parallel with each other, the vaporizing portion of each heat pipe penetrating through and fixedly mounted to the collector plates in intimate heat conductive relation therewith, and each collector plate having a lower portion bent substantially perpendicular to the remaining portion to cover a space between itself and an adjacent collector plate.According to this arrangement, solar heat can be effectively collected by the collector plates and transmitted to the heat pipes with a negligible heat loss. Thus the heat collecting efficiency of the water heater can be remarkably enhanced.

摘要： A method of fabricating an optical waveguide structure includes the step of introducing light into a photo-curable liquid resin. The liquid resin can be a mixture of two types of photo-curable liquid resins having different curing initiation wavelengths and different refractive indexes. The method can include dipping one end of a fiber into the liquid mixture. Light having a wavelength &lgr;1 can be radiated from the tip end of the optical fiber in order to cure one of the photo-curable liquid resins thereby forming a waveguide. Light having a different wavelength &lgr;2 can be radiated from an area surrounding the waveguide so as to cure the liquid mixture and form a cladding portion around the waveguide.

摘要： A plasmid and a DNA fragment each of which contains a gene for tetracycline resistance derived from a glutamic acid-producing coryneform bacterium, and a coryneform bacterium containing said DNA fragment. The gene for tetracycline resistance derived from a glutamic acid-producing coryneform bacterium is a useful selective marker in effecting the breeding of a glutamic acid-producing coryneform bacterium by genetic recombination. Using the plasmid, the DNA fragment or the coryneform bacterium of the present invention, breeding of the glutamic acid-producing coryneform bacterium can be easily and effectively conducted by means of recombinant DNA technique.
