  • Patent number: 7181688
    Abstract: The retrieval condition acquisition unit receives a logical operation expression of the keywords as a retrieval condition from a user. The matching document retrieval unit acquires a list of the document IDs corresponding to the keywords inputted, from the word index of the document information storage unit, and applies a specified logical operation to the result to acquire the matching document IDs. The related keyword calculation unit acquires the keywords extracted from the matching documents retrieved by the matching document retrieval unit as the related keywords, and calculates the degrees of relatedness of each of the matching documents. The related part extraction unit accumulates the degrees of relatedness of the related keywords as to each of the matching documents, and extracts the sentences with the appearance orders in the text kept, in the order of the sentence having a higher accumulated value, until the total length of the sentences extracted becomes longer than a predetermined length.

  • Patent number: 7177572
    Abstract: Electrodes are embedded in a biased charge roller of a xerographic device. The electrodes, which may run the length of the roller, are deposited on an insulating substrate. A semi-conductive conformable layer of a flexible elastomer covers the electrodes. The semi-conductive conformable layer limits current flow between electrodes and relaxes charge deposited on the roller surface. Stationary pre-nip and post-nip contacts apply the bias to the imbedded electrodes. The electrodes in the post nip region are biased to VPOST. The electrodes positioned in the pre-nip regions are either grounded or biased to VPRE<VPOST. The electroded biased charge roller may generate air breakdown in the post nip region, resulting in highly uniform charging.

  • Patent number: 7176952
    Abstract: A fixing device to be installed in an image forming apparatus includes a housing for defining the fixing device. In the housing, a heating member which heats a recording medium onto which a toner image is transferred to fix the image and a pressing member which is brought into press contact with the heating member are provided. In the housing, a first conveyance path and a second conveyance path which has a path different from the first conveyance path is formed. A switching member which switches a destination of the recording medium to the first conveyance path or the second conveyance path is arranged in the housing. As a result, when the image recording medium is sent to a paper reversing device installed in the image forming apparatus, the length of a conveyance path extending to the switching member can be shortened.
