Patent number: 7284899Abstract: Disclosed is an emulsification/dispersion system, which comprises an emulsification/dispersion apparatus, and a multistage depressurization module connected to the outlet side of the emulsification/dispersion apparatus directly or through a heat exchanger. The multistage depressurization module is provided with a plurality of depressurization cells arranged in a multistage manner through seals, and adapted to apply a given backpressure to the emulsification/dispersion apparatus and to reduce the backpressure in a stepwise manner through the series of depressurization cells so as to prevent the occurrence of bubbling even when an emulsified liquid is released to atmosphere. The present invention can prevent the occurrence of bubbling in both processes of forming an emulsified liquid and taking out the emulsified liquid as a product.Type: GrantFiled: January 9, 2003Date of Patent: October 23, 2007Inventor: Mitsuru Nakano

Patent number: 7284716Abstract: Disclosed is an agitating device (3) to be disposed in a batch-type vessel or the like. The agitating device (3) has an upper cover plate (5), a bottom cover plate (6), an impeller (7), an inner screen member (8), and first and second outer screen members (9, 10). When a mixed liquid including a dispersoid and a dispersion medium passes through liquid communication holes (19) of the inner screen member (8) and liquid communication holes (22, 25) of the outer screen members (9, 10) during the course where it flows outward from the impeller (7) to get out of an interplate space, the circumferential component of the flow vector of the mixed liquid is mostly eliminated to allow the mixed liquid to have substantially only the radial component. This prevents the generation of vortexes so as to apply a sufficiently high shearing force to the mixed liquid to effectively prevent the formation of macro bubbles in the mixed liquid.Type: GrantFiled: June 5, 2003Date of Patent: October 23, 2007Inventors: Mitsuru Nakano, Shoji Fukushima, Hisashi Kimura

Publication number: 20070161098Abstract: Lactic acid with high optical purity that has not previously been achieved is produced. It has been found that the optical purity of lactic acid is reduced as the racemization reaction of lactic acid proceeds when lactic acid coexists with glycerol. By reducing the amount of glycerol prior to concentrating lactic acid by heating, the optical purity of lactic acid after concentration by heating can be maintained at a high level.Type: ApplicationFiled: September 7, 2005Publication date: July 12, 2007Inventors: Ikuo Yamaguchi, Osamu Saotome, Shigeru Kuromiya, Tohru Ohnishi, Noriko Yasutani, Satoshi Saitoh, Makoto Mouri, Mitsuru Nakano, Arimitsu Usuki, Nobuhiro Ishida, Kenro Tokuhiro, Eiji Nagamori, Haruo Takahashi

Patent number: 7060735Abstract: A Polymer Electrolyte Membrane is formed by hot air drying of a membrane formed with an acidic main-polymer having proton conductivity and capability of forming an electrolyte membrane (S12), and then immersing it into a basic polymer solution to impregnate the membrane with the basic polymer (S14). The basic polymer is introduced in a large quantity into a site acting as a proton conduction pass of the main-polymer to take charge of the proton conduction. Since in the Polymer Electrolyte Membrane, a base polymer takes charge of proton conduction as compared with the case where proton takes charge of the proton conduction as a hydrate, the base polymer shows favorable proton conductivity even in a low humidity state at an elevated temperature exceeding boiling point of water.Type: GrantFiled: February 21, 2001Date of Patent: June 13, 2006Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takumi Taniguchi, Mitsuru Nakano, Masaya Kawasumi, Yu Morimoto, Naoki Hasegawa

Patent number: 5772929Abstract: The invention relates to a method of manufacturing microcapsules (fat emulsion or liposome) of high stability and smaller mean particle size with a smaller energy and in a shorter treating time. Prior to dispersing a phospholipid treating liquid in a high speed rotary dispersing machine, a treating tank of the high speed rotary dispersing machine is filled up with only the treating liquid. Dispersion of the treating liquid is conducted by rotating at high speed while the treating tank is pressurized to reduce cavitation generation. For precision dispersion of this treating liquid, it is transferred into a precision dispersion apparatus, such as high pressure homogenizer, without contacting with a gas phase. The method reduces the mean particle size of the microcapsules to increase their stability for a long time period.Type: GrantFiled: November 20, 1995Date of Patent: June 30, 1998Assignee: M Technique Co., Ltd.Inventors: Shinichi Enomura, Mitsuru Nakano
