Patent number: 6328886Abstract: The invention concerns a gas diffuser constructed and arranged to disperse gas into a aeration vessel of a water treatment assembly from a blower. The gas diffuser includes main pipes, branch pipes extending between the main pipes and containing gas discharge ports, wherein the branch pipes have a smaller cross-sectional area than the cross-sectional area of the main pipes. The gas discharge ports are further sized, constructed and arranged to reduce the possibility or likelihood of sludge from blocking the ports or entering the branch pipes. This object is achieved either by placement of the ports on the bottom sides of the branch pipes or, alternatively, by construction of the ports to include conduit members, themselves having an arrangement of openings or coverings to prevent or reduce the likelihood of sludge from blocking the ports or entering the branch pipes.Type: GrantFiled: July 7, 2000Date of Patent: December 11, 2001Assignees: Mitsubishi Rayon Co., Ltd., Mitsubishi Rayon Engineering Co., Ltd.Inventors: Satoshi Miyashita, Kenji Honjyo, Osami Kato, Kenji Watari, Takamitsu Takashima, Masanori Itakura, Hiroyuki Okazaki, Ikuo Kinoshita, Noriko Inoue

Patent number: 6325938Abstract: A method for cleaning separating membranes uses a uniquely formulated detergent. The detergent includes a percarbonate-containing, material, existing in the condition in which hydrogen peroxide is adducted in carbonate and is desirably an alkali metal salt. The percarbonate decomposes the organisms deposited on the membrane surfaces while being environmentally desirable. The detergent preferably also includes at least one bivalent iron salt, which improves the cleaning capability of the percarbonate via the so-called Fenton's reaction in which hydrogen peroxide adducted in the percarbonate reacts with the iron ions to form OH— radicals which have a very high oxidative reactivity. The detergent may also contain other oxidizers, a surfactant, a chelating agent, an acid and a pH regulator. The detergent is dissolved in water prior to use.Type: GrantFiled: July 7, 2000Date of Patent: December 4, 2001Assignees: Mitsubishi Rayon Co., Ltd., Mitsubishi Rayon Engineering Co., Ltd.Inventors: Satoshi Miyashita, Kenji Honjyo, Osami Kato, Kenji Watari, Takamitsu Takashima, Masanori Itakura, Hiroyuki Okazaki, Ikuo Kinoshita, Noriko Inoue

Patent number: 6280626Abstract: A membrane separator assembly for separating solids from water includes opposing enclosure wall structures, a membrane module unit, and a gas diffuser disposed below the membrane module unit. The membrane module unit includes a plurality of membrane modules respectively having at least one separating membrane extending between at least two membrane fixing members. At least one of the membrane fixing members has a main passage which is in fluid communication with a membrane passageway. The membrane passageway is accessible to water via permeation through the separating membranes and is inaccessible to solids which are impermeable relative to the separating membranes. The membrane separator assembly is preferably used with a detergent containing percarbonate, preferably sodium percarbonate. The assembly also includes a gas diffuser with two opposing main pipes and branch pipes extending therebetween to avoid undesired pressure differentials when cleaning the assembly.Type: GrantFiled: August 11, 1999Date of Patent: August 28, 2001Assignees: Mitsubishi Rayon Co., Ltd., Mitshubishi Rayon Engineering Co., Ltd.Inventors: Satoshi Miyashita, Kenji Honjyo, Osami Kato, Kenji Watari, Takamitsu Takashima, Masanori Itakura, Hiroyuki Okazaki, Ikuo Kinoshita, Noriko Inoue

Patent number: 5208065Abstract: A process is described for the formation of an undercoat which is in turn useful in forming a CRT metal back layer. According to the process, a pretreatment composition is coated on a glass panel having a fluorescent layer overlaid thereon, so that a water film is formed. The pretreatment composition is composed of 2-20 wt. % of an alkyl monoalcohol having a C.sub.1-3 alkyl group, 0.05-1 wt. % of a water-soluble, high molecular compound and 79-97.95 wt. % of water. An undercoating composition is then coated on the water film by a wet-on-wet coating method, whereby a coating layer is formed. The undercoating composition is composed of 1-7 parts by weight of an acrylic resin, which has been obtained by polymerizing 90-100 wt. % of an alkyl methacrylate having a C.sub.1-4 alkyl group other than tertbutyl methacrylate and 0-10 wt. % of an ethylenically unsaturated monomer copolymerizable therewith, and 99-93 parts by weight of a solvent containing at least 80 wt. % of toluene.Type: GrantFiled: July 17, 1991Date of Patent: May 4, 1993Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Norihisa Osaka, Yukihiro Ikegami, Kiichiro Ishiguro, Shuichiro Tokuda, Masanori Itakura
