| 20090082332 | PURINE DERIVATIVES FOR THE TREATMENT OF VIRAL OR ALLERGIC DISEASES AND CANCERS - The present invention provides compounds of formula (I) | 03-26-2009 |
| 20090114426 | Wired circuit board - A wired circuit board includes a conductive pattern, and an insulating layer covering the conductive pattern and having a transmittance of not more than 30% with respect to a wavelength in a range of 600 to 680 nm. | 05-07-2009 |
| 20090242506 | Wired circuit board and method for manufacturing wired circuit board and mounting electronic component thereon - A wired circuit board is provided having a high-reliability conductive pattern formed thereon and mounting an electronic component thereon with high accuracy, and a method is provided for manufacturing the wired circuit board and mounting the electronic component thereon. An insulating layer including a mounting portion is formed on a metal supporting layer having a specular gloss of 150 to 500% at an incidence angle of 45°. A conductive pattern is formed on the insulating layer. By a reflection-type optical sensor, a defective shape of the conductive pattern is inspected. Then, an opening is formed by etching the portion of the metal supporting layer which is overlapping the mounting portion such that the mounting portion of the insulating layer exposed by etching has a haze value of 20 to 50%, whereby a TAB tape carrier is obtained. Thereafter, an electronic component is aligned with the mounting portion by a reflection-type optical sensor such that the electronic component is mounted on the mounting portion. | 10-01-2009 |
| 20100277835 | PRINTED CIRCUIT BOARD AND MAGNETIC HEAD DRIVING DEVICE INCLUDING THE SAME - A plurality of wiring traces are formed on a base insulating layer, and a metal layer is formed on the opposite surface of the base insulating layer. Two adjacent wiring traces constitute a transmission line pair. The width of the wiring trace is set to not more than 250 μm, and the distance between the adjacent wiring traces is set to not less than 8 μm. The thickness of the base insulating layer is selected to cause differential impedance of the transmission line pair to be not less than 10Ω and not more than 50Ω. | 11-04-2010 |

| 20080212991 | Image forming apparatus - An image forming apparatus which causes a long recording medium carrying a toner image thereon to pass between a fixing roller and a pressure roller to fix the toner image onto the long recording medium by means of the action of heat and pressure. The temperature of the fixing roller is prevented from being significantly reduced during operation of fixing the toner image, and thereby the occurrence of a toner image fixation failure is prevented. When the temperature of the fixing roller is reduced, in addition to a main heating member of heating means, electric power is also supplied from an auxiliary power source to an auxiliary heating member to cause the auxiliary heating member to generate heat. Furthermore, before print operation is started, it is determined, from the temperature of the fixing roller and the pressure roller and the remaining amount of electric power supplied from the auxiliary power source, whether the toner image can be fixed or not over the entire length of the long recording medium, and the print operation is started only when the toner image can be fixed. | 09-04-2008 |
| 20090121423 | Roll sheet conveyance device and image forming apparatus incorporating same - An image forming apparatus includes an image forming device forming an image on a recording medium wound into a roll, and a roll sheet conveyance device unwinding and conveying the medium to the image forming device. The roll sheet conveyance device includes a roll sheet feed device, a torsion detector, and a control device. The roll sheet feed device includes a drive device including upstream and downstream shafts in a drive transmission direction to rotate the medium, and a feed device to feed the medium. The detection device includes a torsion coil spring provided between the upstream and downstream shafts, and a pair of an encoder and an encoder sensor detecting the torsion amount at the opposite ends of the torsion coil spring. The control device controls the torsion amount on the basis of a signal from the detection device, and applies a given back tension to the medium. | 05-14-2009 |
