  • Patent number: 9266106
    Abstract: A convenient technique allows detecting fluorescence emitted in the channel with a uniformly high detection sensitivity and a good reproducibility. On the front face side of a plate-like body 11, a groove-shaped introduction channel 12 and separation channel 14 are formed. In this micro-channel chip 10, on the inner faces of a groove constituting the separation channel 14 formed in a surface of the plate-like body 11, there is formed a fine particle layer 20 provided by sintering fine particles having an average particle diameter of 10 to 500 nm mainly composed of zinc oxide (ZnO) or titanium oxide (TiO2).
    Type: Grant

  • Patent number: 8509657
    Abstract: A two component developer storage product to replenish a two component developer containing at least toner and carrier includes: a cylindrical container having an opening at one end thereof; a lid to close the opening; a toner layer stored in the cylindrical container; and a carrier layer stored in the cylindrical container; wherein the toner layer and the carrier layer are stacked, and the cylindrical container has a spiral projection on an inner spherical surface thereof, and is configured such that when the cylindrical container is rotated, the toner layer and the carrier layer are conveyed by the spiral projection and toner and carrier are discharged from the opening.

  • Patent number: 7962070
    Abstract: Provided is a replenisher developer cartridge for a trickle developing system image forming apparatus producing no image problem such as image density unevenness, image roughness or the like. Not only an image forming apparatus by which high quality images are stably output, and a replenisher developer cartridge for the image forming apparatus were possible to be provided, but also durability of a two-component developer used in the image forming apparatus was possible to be improved, by replenishing the image forming apparatus with a replenisher developer in the carrier concentration range of 5-30% by weight in terms of the mean value, and in the carrier concentration deviation range of 10% by weight or less, based on the replenisher developer.
