摘要： The exhaust gas purification device includes: a substrate including an upstream end through which an exhaust gas is introduced and a downstream end through which the exhaust gas is discharged; a first catalyst layer containing a rhodium-containing catalyst containing a metal oxide carrier and rhodium particles supported on the metal oxide carrier, the first catalyst layer extending across a first region; and a second catalyst layer containing palladium particles and a material having a basicity higher than a basicity of the metal oxide carrier, the second catalyst layer extending across a second region. A mean of a particle size distribution of the rhodium particles is from 1.5 nm to 18 nm.

摘要： [Subject] To provide laser Doppler blood flow measuring method and device which achieve multi-dimensional measurement efficiently at a high degree of accuracy over a wide range with a simple optical system and device.[Solving Means] Laser light from a semiconductor laser 12 is split and formed into sheet lights Ls using a cylindrical lens 22, and the sheet lights Ls are crossed with each other at a predetermined position. A lens system 30 configured to form an image of scattered lights into a linear shape at a linear irradiation site Lx where the sheet lights Ls cross with each other is provided. An optical fiber array 32 having a plurality of optical fibers 34 is provided at an image-forming position of the lens system 30. Avalanche photodiodes 42 configured to convert the scattered lights which are shifted in frequency by the Doppler effect caused by the blood flow into electric signals for the each optical fiber 34 are provided. The blood flow velocity in a tissue of a biological body at the linear irradiation site Lx is calculated from the scattered lights transformed from the laser light by being shifted in frequency by the Doppler effect and is scanned for the each optical fiber 34, whereby the blood flow velocity in the blood vessel in a predetermined area in the biological body is calculated.
