    摘要： A method of producing uniform inorganic microspheres with a particle size of 0.01 to 500 .mu.m by injecting an aqueous solution containing a particle-forming material into an organic solvent. The method includes injecting the aqueous solution into the organic solvent through a macromolecular membrane having a hydrophobic surface and having pores substantially uniform in pore size and extending in the direction of thickness of the membrane, substantially straight through the membrane, so that a path length of each of the pores corresponds substantially to a thickness of the membrane, to form, in said organic solvent, a large number of emulsion particles substantially uniform in size and then producing uniform inorganic microspheres from said emulsion particles on a one emulsion particle-to-one microsphere basis. The pores in the membrane are formed by either a corpuscular or laser beam.

    摘要： In the method for measuring the velocity of fluid or visualizing the distribution of fluid by feeding tracer particles to the fluid, irradiating the fluid with light and observing return light from the tracer particles, tracer particles containing a fluorescent substance are fed at least partially to the fluid and the fluid is irradiated with exciting light to cause the tracer particles to output fluorescent emissions. A filter which does not transmit the exciting light is used to substantially selectively observe the fluorescent emissions of the tracer particles. This method results in a remarkable improvement in the accuracy of flow velocity measurement or visualization of fluid distribution. Moreover, in a mixed fluid system consisting of two or more different fluids, the pattern of behavior of each fluid and the intermingled state of the fluids can be observed by using a plurality of different tracer particles.

    摘要： In the method for measuring the velocity of fluid or visualizing the distribution of fluid by feeding tracer particles to the fluid, irradiating the fluid with light and observing return light from the tracer particles, tracer particles containing a flourescent substance are fed at least partially to the fluid and the fluid is irradiated with exciting light to cause the tracer particles to output flourescent emissions. A filter which does not transmit the exciting light is used to substantially selectively observe the flourecent emissions of the tracer particles. This method results in a remarkable improvement in the accuracy of flow velocity measurement or visualization of fluid distribution. Moreover, in a mixed fluid system consisting of two or more different fluids, the pattern of behavior of each fluid and the intermingled state of the fluids can be observed by using a plurality of different tracer particles.

    摘要： A nitride semiconductor ultraviolet light-emitting element is formed by laminating at least an n-type cladding layer configured of an n-type AlGaN semiconductor layer, an active layer including an AlGaN semiconductor layer having band gap energy of 3.4 eV or larger, and a p-type cladding layer configured of a p-type AlGaN semiconductor layer. A p-type contact layer configured of a p-type AlGaN semiconductor layer that absorbs ultraviolet light emitted from the active layer is formed on the p-type cladding layer. The p-type contact layer has an opening portion penetrating through to a surface of the p-type cladding layer. A p-electrode metal layer that makes Ohmic contact or non-rectifying contact with the p-type contact layer is formed on the p-type contact layer so as not to completely block the opening portion. A reflective metal layer for reflecting the ultraviolet light is formed at least on the opening portion and covers the surface of the p-type cladding layer that is exposed through the opening portion either directly or through a transparent insulating layer that allows the ultraviolet light to pass therethrough.
