This is a proposal of a measurement system that performs a useful three-dimensional visualization of airflow temperature distribution in the development of energy-saving equipments. You can visualize the temperature distribution by melting and spraying a fluorescent dye disolved in a glycol-based solvent and irradiateing with a laser in the atmosphere.
We have the ERF actuator using a sheet , focusing on the mesh size of the sheet, the surface roughness of the electrode and the material of the electrode. As a result of experiments related with these factors and resistance force, we have obtained a larger resistance force than ever before.
Auscultation has been used for various diagnoses since ancient times, however the accuracy is depend on doctor's proficiencies. Therefore there is a need for an alternative system to this auscultation or a supporting system. In this presentation, we introduce a vascular stenosis diagnosis supporting apparatus using sounds of the shunt blood flow in patients with renal failure. We also introduce examples of fault or defect diagnosis in the industrial applications.
A new method for low-temperature nitridation of oxides at ca. 250 oC was developed. This technique has the advantage of limitting the use of toxic ammonia gas and organic solvants, and allows us to produce nano-sized oxynitrides and nitrides.
We investigate about thermoelectric properties of tungsten bronze-type and Spinel-type oxides. We obtained enhanced properties by reducing under controlled-condition or extracting constituent metal ions.
The technique to reduce the manufacturing cost of n-type silicon crystals. The modified technique using the merits of the zone melting method that long single crystals with uniform dopant distribution can be grown even if the segregation coefficient of the dopant is too small. The technique to enlarge the diameter of the grown crystals.
Polymer particles were prepared by a CO2 laser supersonic atomizing process. The CO2 laser supersonic atomizing was carried out by irradiating the laser to fiber in a supersonic jet and obtained micro- and nano-particles with the high particle sphericity. This technique is a novel method for producing polymer particles.
