  • Patent number: 7839473
    Abstract: In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix (6) is made larger above the region between adjacent ITO transparent electrodes (3) and is made smaller above the region between adjacent Al reflective electrodes (4). This enables a transmissive portion to offer a display with high contrast that does not suffer from afterimage or the like by shielding light from the domain lying between the adjacent pixels, and the reflective portion to offer a brighter display by increasing the aperture ratio thereof by making the black matrix width as small as possible or forming no black matrix.

  • Patent number: 7836639
    Abstract: There is provided a structure mounting and supporting device that can facilitate mounting a structure on a roof. The device allows a plurality of fixing members to be fixed to sheathing, which underlies a roofing material, perpendicularly, while allowing a supporting member fixing and supporting the structure and the fixing members to be fixed together at their respective side portions. More specifically, the supporting member to be carried by the plurality of fixing members has one end initially connected to one fixing member. The supporting member thus has the other end pivotably to provide a degree of freedom to a position at which the other fixing member and the supporting member are secured together, in mounting and fixing the fixing member and the supporting member together. The structure mounting and supporting device is thus applicable to a roof having a plurality of pieces of sheathing inclined at different angles.

  • Patent number: 7840999
    Abstract: An image processing apparatus authorizing the use thereof by carrying out user authentication prevents fraudulent use of the processor and/or a data leak due to a user's forgetting invalidation of authentication or other reason. When a user is authenticated, whether the user is authorized to use a DMFP is determined by comparing the user's input information with the information of an access-authorized person stored in the DMFP. When both information matches, a range of functions available for the user are specified, and the user is authenticated. Subsequently, for example, operation of copy setting is carried out in making setting on the DMFP. When the setting operation is over, whether authentication on the user is invalidated is determined to execute processes of copy setting, etc. In response to a trigger of invalidation of authentication on the user, the processes of copy setting, etc., are started.

    Abstract: An image forming apparatus for stabilizing image densities of a high-density image by devising shapes of test patches is provided. A test pattern image is created by adhering toner to a plurality of test patches having respectively different line area rates of 100% or less. An amount of adhering toner for a line area rate of 100% is calculated by detecting the amount of the toner adhering to the test pattern image. Then, process conditions are controlled so that the calculated amount of the adhering toner reaches a predetermined value. By doing so, the amount of the adhering toner of the high-density image is accurately controlled.
