  • Publication number: 20240123405
    Abstract: A solid type nano-pore sequencer is arrayed easily. In a liquid column separation device including first and second base materials, a liquid feeding unit supplies fluids to a gap between the two base materials. Hydrophilic and hydrophobic regions are disposed on a surface of the second base material, and the hydrophilic region is disposed to oppose a predetermined position of the first base material where a substance to be measured is made to pass through. Also, a flow passage space includes at least one inlet and outlet through which fluids can flow in and out. A representative length of the hydrophilic region is made larger than a distance between the first and second base materials, and thereby a liquid column capable of connecting the first base material and the second base material is formed by making two or more immiscible fluids to flow by the liquid feed unit.

  • Patent number: 7630654
    Abstract: A plurality of chambers are adapted to accommodate a plurality of cartridges each containing toner to be used for printing. A mode changer is operable to change an operation mode of the printing apparatus in accordance with a combination of respective colors of toner in the cartridges accommodated in the chambers. A first detector is operable to detect a residual amount of toner in each of the cartridges. A second detector is operable to detect the respective colors of toner in the cartridges when the operation mode is changed. A controller is operable to generate an image data including a plurality of first identifiers each indicative of the residual amount of toner in one of the cartridges and a plurality of second identifiers each indicative of one of the colors of toner and associated with one of the first identifiers. A display is adapted to display the image data.

  • Patent number: 7447459
    Abstract: The present invention provides an image formation device having a plurality of startup modes in dependence upon the toner cartridge installed, with which the user can perform alteration of the startup mode in a simple and easy and moreover accurate manner. This image formation device is one to which a development unit containing toner is installed in a removable manner and which performs image formation using the toner contained in the development unit, and having a plurality of startup modes depending upon the installed development unit; the device including: a reception portion which receives an alteration request for the startup mode; a decision portion which, upon receipt of the alteration request, determines the development unit that is required to be operated, in order to startup in the requested startup mode; and an output portion which outputs guide information to the user, so that the determined development unit is operated.

  • Patent number: 7236725
    Abstract: An image formation device has an image carrier in which are formed latent images, and a development device into which development units housing toner are detachably installed. When development units with a plurality of colors are installed in respective installation positions of the development device, the image formation device operates in color printing mode, and when at least one black development unit is installed in any among the plurality of installation positions, and at least one among the development units with the colors other than black is not installed, even if at least one development unit in the plurality of colors other than black is installed, the image formation device operates in monochrome printing mode. When any of the C, M, and Y development units is removed from color mode state, the image formation device operates in monochrome printing mode.
