Publication number: 20080193379Abstract: It is intended to provide a radioactive diagnostic imaging agent comprising a radioactive halogen-labeled compound as an active ingredient, in which the active ingredient is prevented from radiolysis and its stability is improved. This is achieved by adding a biologically-acceptable sugar or sugar alcohol to the radioactive diagnostic imaging agent in an amount effective to prevent radiolysis. The amount of the sugar or sugar alcohol to be added is preferably 10 (mmol/L)/GBq/mL or more, and more preferably 50 (mmol/L)/GBq/mL or more. The sugar is preferably selected from the group consisting of erythrose, threose, ribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose, talose, erythrulose, ribulose, xylulose, psicose, fructose, sorbose, and tagatose. The sugar alcohol is preferably selected from the group consisting of erythritol, xylitol, sorbitol, and mannitol.Type: ApplicationFiled: June 8, 2006Publication date: August 14, 2008Applicant: Nihon Medi-Physics Co., Ltd.Inventors: Takayuki Shimada, Akira Nakatani, Keietsu Takahashi

Patent number: 7250991Abstract: A signal line and a pixel capacitor wire that doubles as a pixel capacitor electrode are fabricated parallel to each other from the same electrode layer through patterning thereof. Therefore, no additional steps are required to form the pixel capacitor wire. In such an arrangement, the pixel capacitor wire and the signal line are disposed parallel to each other; therefore, delays of signal transmission in the signal line and crosstalk between pixels are prevented from occurring. The active matrix substrate incorporating this arrangement is suitably used in liquid crystal display devices, image sensors, and the like. Similar advantages are available with an arrangement in which the signal line and the pixel capacitor wire are disposed parallel to each other, and the storage capacitor electrode, which will constitute a storage capacitor with the pixel electrode therebetween, and the scanning line are fabricated from the same electrode layer through patterning thereof.Type: GrantFiled: March 10, 2004Date of Patent: July 31, 2007Assignee: Sharp Kabushiki KaishaInventors: Hisashi Nagata, Yoshihiro Izumi, Takayuki Shimada

Patent number: RE40771Abstract: A liquid crystal display device is formed by arranging a plurality of scanning lines 31, 32, . . . to which scanning signals are successively applied and a plurality of signal lines 41, 42, . . . to which data signals are successively applied to intersect at right angles. Mounted in the vicinity of each of the intersections of the scanning lines 31, 32, . . . and signals lines 41, 42, . . . are a TFT 5 electrically connected to both of the lines, and a pixel electrode 6 connected to the TFT 5. A common electrode is placed to face the pixel electrode 6 with liquid crystals 2 therebetween. One of electrodes of a pixel capacitance formed by the pixel electrode 6 is connected to a common line 9 for supplying a common signal to the common electrode 7. A dummy scanning line 30 for forming a capacitance is arranged outside of the scanning line 31 located at the outermost position on a scanning start side of scanning signal.Type: GrantFiled: February 2, 2001Date of Patent: June 23, 2009Assignee: Sharp Kabushiki KaishaInventors: Shinya Tanaka, Takayuki Shimada, Takashi Ochi, Yuzuru Kanemori, Mikio Katayama
