Patent number: 8268017Abstract: Provided are a method of stabilizing a leuco dye storable as a liquid for a long time, a method of reducing nonspecific color development thereof at a time of a color development reaction, and a stable liquid reagent composition using the methods. The inventors of the present invention found that coexistence of the leuco dye with a specific reducing agent resulted in suppression of self color development and its remarkably improved stability in a solution, and that when a color development reaction of the leuco dye with hydrogen peroxide was performed, coexistence of the leuco dye, in a reaction solution, with another dye which had an absorption spectrum not influencing a measurement wavelength of the leuco dye and did not react with hydrogen peroxide suppressed nonspecific color development and lowered a reagent blank value, which was applied to an analytical reagent.Type: GrantFiled: February 21, 2008Date of Patent: September 18, 2012Assignee: Asahi Kasei Pharma CorporationInventors: Shigeru Ueda, Takeshi Matsuoka, Akihiko Kan

Patent number: 7262877Abstract: An image input-output apparatus is provided with a printing function for printing an image specified by print data from an external device and a reading function for reading an original image. The apparatus includes a printing function realizing unit, a discrimination unit, and a control unit. The printing function realizing unit operates in a first mode for realizing the printing function with a relatively small memory capacity and operates in a second mode for realizing the printing function with a relatively large memory capacity. The discrimination unit discriminates whether printing of the image specified by the print data is to be realized by the first mode or the second mode. If it is discriminated that printing is to be realized by the first mode, the control unit is adapted to allow parallel execution of the printing function and the reading function. Otherwise, parallel execution is inhibited.Type: GrantFiled: March 9, 2005Date of Patent: August 28, 2007Assignee: Canon Kabushiki KaishaInventor: Shigeru Ueda
