Abstract: PURPOSE:To recover Pt from a used phosphoric acid type fuel cell contg. Pt supported on C by a dry process without using aqua regia or a reducing agent or requiring the treatment of waste water by heating the combustion residue of the cell. CONSTITUTION:Pt, P, Si, Al, Fe, Ca and Mg have been detected in part of a used fuel cell as a sample by a spectroscopic qualitative analysis, and about 2.41wt% Pt content and about 2% ash content have been given by a quantitative analysis. The sample is burned at about 900 deg.C for about 5hr in an electric furnace while a small amount of O2 is blown. The resulting combustion residue is slowly cooled and put in an alumina crucible, and while O2 is blown from the top of the crucible at about 10ml/min rate, high frequency induction heating is carried out in the air to melt Pt. SiO2, Al2O3, CaO, Fe2O3 and MgO rise to the upper part of the crucible by the difference in specific gravity between the oxides and Pt, so the oxides can be separated from the molten Pt.

Title: Crystal-orientation measuring method of lightguide-type nonlinear optical element
IPC: G01N21/63
Filed: 1992-03-23
Abstract: PURPOSE:To measure the crystal orientation of a core accurately, positively and simply by casting laser light on the core of a lightguide-type nonlinear optical element from the direction, which is perpendicular to the advancing direction of light, generating the higher harmonic wave, and measuring the intensity of the higher harmonic wave. CONSTITUTION:Laser light 6, which is polarized with a polarizer (r), is cast on a core 41 from the direction, which is perpendicular to the advancing direction of a fiber-type nonlinear optical element 4. The second higher harmonic wave, which is generated from the nonlinear optical material of the core 41, is transformed into the parallel light by a lens 2. After the laser light is removed with a filter F, the intensity of the higher harmonic wave is measured with a photomultiplier P. At this time, the higher harmonic wave 5 is generated in the direction of a dielectric main axis (i), which is perpendicular to an dielectric main axis (j) of a crystal, becomes the maximum value when the polarization of the laser light 6 agrees with the main axis (j) and becomes the minimum value when the polarization agrees with the main axis (i). Therefore, the orientation of the dielectric main axis of the crystal in the core 41 can be directly measured by turning the polarizing direction of the laser light with the polarizer (r) and measuring the intensity of the generated higher harmonic wave 5.

Filed: 1993-03-24
Abstract: PURPOSE:To reduce air resistance by setting a car body external surface form so that an air flow velocity on the upper surface of a car body is approximately equal to that on the side surface thereof. CONSTITUTION:A car body external form is set so that an air flow velocity on the upper surface of a body 2 becomes approximately equal to that on the side surface of it. Also the body external form is set so that the air flow on the upper surface of the body is separated from that on the side surface. Instead the body external form is set so that air flow at the fore body part of the body 2 becomes a two-dimensional flow, and that at the after body part produces a closed separation type wake. By setting the form like this, occurrence of vertical vortex between the upper and side surface flows on the body 2 is suppressed, and a separation flow occurrence position on the after body part is moved backward of the body as far as possible by the two-dimensional flow at the fore body part. By their multiplied action, the closed separation type wake is generated to reduce air resistance.
