  • Patent number: 8263305
    Abstract: Provided is a method for producing a toner having excellent particle size distribution and storage stability. The method set forth in the present specification is a method for producing a toner by aggregating and fusing base microparticles whose main component is a binder resin including anionic groups, wherein an aggregate is produced by aggregating the base microparticles in a base microparticle suspension, in a presence of a non-ionic surfactant such that a surface tension of an aqueous solution thereof is not lower than 45 mN/m at any concentration at or above a critical micelle concentration, and the toner is produced through fusion of the aggregate. According to this method, drops in a glass transition temperature of the toner can be curbed, and the toner having excellent storage stability and good particle size distribution can be obtained.

  • Patent number: 8119319
    Abstract: The present teaching provides a method for producing a positive charging toner that can exhibit stable charge characteristics. According to the present teaching, a positive charging toner is produced by preparing a base particle suspension having a conductivity not higher than 70 ?S/cm and comprising base particles that are obtained by mixing and emulsifying an aqueous medium and a resin solution containing the polyester resin; producing toner base particles by mixing the base particle suspension with a charge control resin microparticle suspension containing charge control resin microparticles; causing the charge control resin microparticles to adhere to the surfaces of the base particles; and washing the toner base particles.

  • Patent number: 5808449
    Abstract: A method for detecting islanding operation of a rotating-machine type dispersed generator. The dispersed generator is interconnected with a main electric source through a circuit breaker to constitute an electric power system. The estimating method is implemented as follows: (a) changing electric power of the electric power system; (b) detecting frequency component of the electric power; and (c) deciding that an islanding operation of the dispersed generator is executed if the change of the frequency component becomes greater than a predetermined value. With this method, it becomes possible to detect the islanding operation of the dispersed generator even if the power flow at the interconnecting circuit breaker is generally zero.
