  • Publication number: 20160194214
    Abstract: Provided are: an alkali metal titanium oxide having a uniform composition and that is such that there are no residual by-products having a different composition or unreacted starting materials; and a method for producing a titanium oxide and proton exchange body obtained by processing the alkali metal titanium oxide. The method produces an alkali metal titanium oxide by firing the result of impregnating the surface and inside of pores of porous titanium compound particles with an aqueous solution of an alkali metal-containing component. The alkali metal titanium oxide is subjected to proton exchange, and with the proton exchange body of the alkali metal titanium oxide as the starting material, the titanium oxide is produced through a heat processing step.

  • Publication number: 20160190574
    Abstract: Provided are an alkali metal titanium oxide and titanium oxide that have a novel form and are industrially advantageous. The alkali metal titanium oxide is obtained by firing the result of impregnating the surface and interior of pores of porous titanium compound particles with an aqueous solution of an alkali metal-containing component, and has the form of secondary particles resulting from the aggregation of primary particles having an anisotropic structure. The titanium oxide is obtained using the alkali metal titanium oxide as a starting material. The secondary particles can further assume a clumped structure, have a suitable size, and are easily handled, and so are industrially advantageous. In particular, the H2Ti12O25 of the present invention is an electrode material that is for a lithium secondary battery, has a high capacity and a superior initial charging/discharging rate and cycling characteristics, and has an extremely high practical value.

  • Patent number: 8448917
    Abstract: To reduce invasion and adhesion of foreign matters into and onto the gating-member retreat room in the transition from the gate-open state to the gate-close state including retreat and on-shutting-movement of the gating-member. The shutter, being moved in the shuttering movement room, shuts the entrance aperture by making the shutter sealing contact with the stationary seal by such movement of the shutter itself when the gating-member is accommodated in the gating-member retreat room, and, also being moved in the shuttering movement room, shuts the entrance aperture by making the shutter sealing contact with the second gate seal by such movement of the shutter itself when the gating-member, being moved in the shuttering movement room, shuts the exhaust port by making the first gate seal contact with the stationary seal by such movement of the gating-member itself.

  • Publication number: 20090128590
    Abstract: For controlling the tone of the printed matter, the measurement data is stably obtained against various error factors and the ink supply is precisely controlled. The process data 11 is used as target data of the print matter. The dot area rate in the process data is calculated along the paper transport direction within the ink key width. Then, the selective integral and averaging 23 is executed on the calculated dot area rate greater than a prescribed threshold and the dot area rate in the actually printed matter at points corresponding with each other. The tone is controlled on the basis of the control quantity such as the ink key opening and the ink source opening obtained on the basis of the dot area rate and the spectral reflection rate as calculated by the selective integral and averaging.

  • Publication number: 20080127846
    Abstract: A color measuring unit measures color tone of an image printed on a test sheet. An arithmetic unit compares color tone set based on print production format (PPF) data with the color tone measured by the color measuring unit to set a color-adjustment amount. An operator selects an ink key zone for color adjustment while viewing the image using an operating unit, and sets a corrected color-adjustment amount for the ink key zone. Based on the color-adjustment amount and the corrected color-adjustment amount, an ink- supply amount is adjusted for the ink key zone.

  • Publication number: 20080072778
    Abstract: An image is created from PPF data and the image is displayed. An operator inputs a pre-set value of color adjustment from a color-adjustment-quantity operation screen. The color-adjustment-quantity operation screen includes a print display unit that displays a print color in a print measured by a calorimeter, a color-sample display unit that displays a target color in a color sample measured by the calorimeter, and a corrected-color display unit that displays a corrected color corresponding to a deviation between a calorimetric value of the print and a calorimetric value of the color sample.
