  • Publication number: 20060033040
    Abstract: A radiation detecting apparatus includes a sensor panel 100, a phosphor layer 111 formed on the sensor panel 100 to convert a radiation into light, and a phosphor protecting member 110 covering the phosphor layer 111 to adhere closely to the phosphor protecting member 110. The phosphor protecting member 110 includes a phosphor protecting layer 116 made of vapor deposition polymerization polyimide formed by vapor deposition polymerization, a reflecting layer 113 reflecting the light converted by the phosphor layer 111, and a protecting layer 117 made of vapor deposition polymerization polyurea formed by the vapor deposition polymerization. By such a configuration, a polymerization reaction of the phosphor protecting layer 116 is performed on the substrate. Thereby, the generation of by-products is suppressed to make it easy to acquire the uniformity of film quality.

  • Patent number: 6795669
    Abstract: A first control member is disposed in a drum shaft away from a photoconductive drum, and a second control member is disposed in a roller shaft away from a transfer roller. The first and second control members abut on each other at their circumferential surfaces. This helps reduce an amount of displacement resulting from an impact caused by insertion of a recording paper sheet in between the photoconductive drum and the transfer roller, and thereby reduce vibrations in the photoconductive drum. Consequently, a toner image formed on the photoconductive drum and an unfixed toner image transferred onto the recording paper sheet are not affected by vibrations, so that a high-quality image is obtained that is free from blurriness or irregularities.

  • Publication number: 20040022566
    Abstract: An image forming apparatus, determining in sorting recording sheets whether or not recording sheet transport interval is shorter than a first predetermined value, sets the longest time settable as a delay time when the interval is longer than the first value. When the interval is shorter than the first value, the apparatus, determining whether or not the interval is shorter than a second predetermined value, sets the shortest delay time settable when the interval is shorter than the second value, and sets a reference delay time when the interval is longer than the second value. The apparatus prevents sheet jam before a sheet eject mechanism by ensuring that the mechanism returns to an initial position before the front end of a following sheet reaches sheet eject rollers after the rear end of a preceding sheet passes through the rollers.
