| 20110079007 | HEAT ENGINE - A heat engine is provided which includes: a boiler unit including an evaporation chamber and a fluid-pool chamber, the evaporation chamber heating a working fluid by supplied heat and generating vapor of the fluid, and the fluid-pool chamber collecting the fluid supplied to the evaporation chamber; an output unit through which the vapor flows, and which converts energy of the vapor to mechanical energy; a condensation unit which condenses the vapor that has passed through the output unit, and refluxes the condensed fluid to the fluid-pool chamber; and a working fluid guide member which is disposed in the boiler unit, and which sucks the fluid in the fluid-pool chamber by using capillary force and supplies the fluid to the evaporation chamber. The evaporation chamber is separated from the fluid-pool chamber. Pressure in the evaporation chamber is higher than pressure in the fluid-pool chamber. The working fluid guide member satisfies (2σ/r)·cos θ>PH−PL. | 04-07-2011 |

| 20090231591 | Method, Apparatus, and Program for Measuring Wavelength Dispersion of Optical Waveguide - The invention is to provide a wavelength dispersion measuring method for an optical fiber capable of measuring a wavelength dispersion in a section extending from an incident end of the optical fiber to an arbitrary point along the way by using a scattering phenomenon in which a scattering coefficient at a local point on the optical fiber is independent of time. Incident light having a known spectral density function S(ω) is caused to be incident on the optical waveguide, and a wavelength dispersion of the section extending from the incident end of the optical waveguide to the arbitrary point along the way by a correlational function between a signal being proportional to a scattered light amplitude generated at a first halfway point and a signal being proportional to a scattered light amplitude generated at a second halfway point. | 09-17-2009 |
