|20110063609||Spectroscopy method and spectroscope - A spectroscopy method, includes guiding pulse laser light to an optical fiber, which mutually reacts with a sample to be measured of a light absorptance characteristic, outputting ring down pulse light obtained through light absorption of the sample, measuring an absorptance characteristic of the sample based on an attenuation characteristic of the ring down pulse light, and setting the pulse laser light as wide-spectrum laser light, setting the optical fiber as a strong dispersive optical fiber, and increasing a pulse width of the ring down pulse light to measure a wavelength absorptance characteristic based on a ring down attenuation constant of a pulse train with respect to a time sequence corresponding to a wavelength.||03-17-2011|
|20110042008||PLASMA GENERATOR - To provide a plasma generator having a plasma-generating zone of an increased volume.||02-24-2011|
|20100258247||Atmospheric pressure plasma generator - According to the present invention, a long electric discharge path is formed, and a workpiece is irradiated with an atmospheric plasma of a long rectangular area. An argon flow at a first gas outlet forms argon plasma by high-frequency electric power between the first and second electrodes, and the plasma is jetted as an auxiliary plasma in the longitudinal direction from the left end of a primary plasma-generating zone. Another argon flow at a second gas outlet forms argon plasma by high-frequency electric power between the third and fourth electrodes, and the plasma is jetted as an auxiliary plasma in the longitudinal direction from the right end of the primary plasma-generating zone. When high-frequency electric power is applied to the first and third electrodes, electric discharge occurs between two argon plasmas flowing from both ends of the primary plasma-generating zone. Through the electric discharge, the discharge state is maintained in the entire primary plasma-generating zone. Then, oxygen and argon are supplied through gas mixture (argon and oxygen)-supplying pipes to the plasma-generating zone, oxygen plasma is generated. The oxygen plasma is jetted through 170 second holes disposed at the bottom side wall of the cylindrical section to the outside in a direction normal to the side wall, whereby a workpiece is irradiated with oxygen plasma in a long belt-like area having a length of 50 cm.||10-14-2010|
|20090237667||Particle density measuring probe and particle density measuring equipment - Disclosed is a particle density measuring probe for measuring the density of atoms or molecules in a plasma atmosphere by absorption spectroscopy. The probe has a cylindrical light guiding member provided in the plasma atmosphere. At the front end of the light guiding member, there is provided a reflection plate for reflecting light that has propagated through the cylindrical light guiding member. Behind the reflection plate, in a cross section perpendicular to the longitudinal direction of the light guiding member, a part devoid of a portion of wall surface is provided by a predetermined length in the longitudinal direction. A plasma introducing portion allows mutual contact between light passing through this part devoid of a portion of wall surface and atoms or molecules in the plasma atmosphere. The probe has a main body that guides light in an axial direction by total reflection by a side wall, and that is located behind the plasma introducing portion.||09-24-2009|
|20080239312||Atomic analyzer - [Object] To identify and quantitate an atom of a solid element contained in sludge, waste fluid, or soil.||10-02-2008|
