Title: Puffer type gas circuit breaker
Inventor: KOJIMA OSAMU
IPC: H01H33/91
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To improve circuit breaking performance by providing gas flow blasted from a puffer chamber to flow smoothly without generating a turbulent flow or staying, and increasing a blast of insulating gas to an arc by increase of density and flow speed of the insulating gas. SOLUTION: A gas communication passage 8 formed in a partition wall 7 between a puffer chamber 6 and a nozzle 3 is formed to provide a component of flow directing from the outer circumferential side toward the center side, and a component of flow which turns in the circumferential direction. Because gas blasted from the puffer chamber spirally turns to flow toward an arc, linearity of gas flow is improved, so the arc is rolled into a turn of the gas flow to increase an arc length, and that peripheral gas is rolled into the turn of gas flow to increase gas density and gas flow speed. As a result, circuit breaking performance of a puffer type gas circuit breaker is improved.

Title: Light guide
Inventor: KORUNERIUSU KUREEMAA
IPC: G02B6/12
Filed: 1990-09-17
Abstract: PURPOSE: To generate a plasmon by forming a layered or stripped optical waveguide from a waveguide layer having a refraction factor step to the surroundings so as to reduce the difference between the propagation speed of TE mode polarization and the propagation speed of TM mode polarization inside the waveguide layer. CONSTITUTION: Concerning the layered or stripped optical waveguide provided with a waveguide layer 2 of a dielectric, a metal layer 3 is arranged proximately to the waveguide layer 2. Therefore, the propagation speed of a photon polarized in the TM mode among the photons polarized in the TE mode and TM mode so as to be propagated inside the waveguide layer 2 is decelerated by the metal layer 3. Thickness t3 of the metal layer 3 is selected thin so as to still propagate the photons polarized in the TE mode and TM mode inside the waveguide layer 2.  On a metal boundary face, the surface plasmon existent only in the TM mode polarization can be propagated so that only one polarizing direction can be suitably affected by the metal layer and the propagation speed of plasmons can be mainly applied by the layer thickness of metal, the relative dielelctric constant of metal and the relative dielectric constant of the surrounding dielectric.
