JOURNAL FREE ACCESSIn recently, mesh nozzle nebulizer was caused problems of such as nebulizer disorder(Liquid leaking, not in spray). This work used various kinds of metallic nozzles for neburizer. Several liquid, such as skin lotion and solution for cleaning air, were sprayed by these nebulizers. The elution of metals in sprayed solution was analyzed. We show the obtained results with some elucidations.View full abstractDownload PDF (442K)

JOURNAL FREE ACCESSRecently, air bearings are used in high speed and light weight machinery because of their low friction, low environmental load, maintenance-free and so on. On the other hand, the air bearings have low resistant against the outer vibration. Therefore it is important to enhance the stiffness of the bearing. Under the back ground, the authors proposed the high stiffness air bearing which is designed by using the newly developed geometrical optimization method and we conclude the reason for obtaining the high stiffness as generating the negative pressure in the outer vicinity of bearing surface. However, the negative pressure has not been confirmed experimentally yet. In this study, the pressure distribution and load carring capacity of the optimized thrust air bearing are measured under several film thickness conditions by using the high speed experimental setup and then, the reason why the high stiffness is obtained in the optimized bearing was discussed.View full abstractDownload PDF (872K) -

JOURNAL FREE ACCESSElectrically conductive composite film was prepared from dispersion fluid of carbon nanotubes (CNT) and fluorine resin paint (Navaron). This composite film was applied to the bipolar plates of the fuel cell. The fuel cells assembled from the bipolar plats coated with the composite film showed output power of 2.5W, which was 1.8 times higher than that of uncoated biplar plates. The coating of the composite film reduced the contact resistance between the bipolar plate and the membrane electrode assembly (MEA).View full abstractDownload PDF (449K)
