Patent number: 6938495Abstract: 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.Type: GrantFiled: July 24, 2001Date of Patent: September 6, 2005Assignees: Osaka Gas Company Limited, Liquid Gas Co., Ltd.Inventors: Akira Hirano, Masahide Tsujishita, Hisao Ohnishi, Masashi Nishigaki, Masamichi Ippommatsu, Tsuyoshi Tsurutani

Patent number: 5376347Abstract: 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.Type: GrantFiled: July 15, 1992Date of Patent: December 27, 1994Assignees: Osaka Gas Company, Limited, Liquid Gas Co., Ltd., Suzuki Yushi Industrial Co., Ltd.Inventors: Masamichi Ipponmatsu, Masashi Nishigaki, Akira Hirano, Tsuyoshi Tsurutani
