摘要： A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety or sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.

摘要： A belt driving controller is disclosed. The belt driving controller executes driving control of a belt that is wound around plural sustaining rollers by controlling a driving sustaining roller that transmits driving force to the belt. The belt driving controller executes the driving control of the belt by controlling the driving sustaining roller so that a moving velocity fluctuation of the belt caused by a PLD (pitch line distance) fluctuation in the belt circumference direction becomes small, based on rotation information of rotation angle displacement or rotation angle velocities of two sustaining rollers in the plural sustaining rollers, in which two sustaining rollers, the diameters thereof are different from each other and/or the degrees to which the PLDs of parts of the belt which wind around the two sustaining rollers influence the belt moving velocity and the rotation angle velocities of the two sustaining rollers are different from each other.

摘要： A rotational speed of a first roller and a time required for a second roller to make one rotation are measured. A controller calculates an amplitude and a phase of fluctuation in a rotational speed in one rotation period of the first roller while the first roller is rotated by a predefined angle based on the speed and the time. The controller corrects measured speed of the first roller based on the amplitude and the phase, and controls a driving roller based on corrected speed.

摘要： An image forming apparatus of the present invention includes at least one rotatable image carrier, an image forming device for forming different images on the image carriers, a first image transferring device for transferring the images from the image carriers to a first image transfer body driven to move via a first image transfer position where it faces the image carriers, and a second image transferring device for transferring the resulting composite image from the first image transfer body to a second image transfer body driven to move via a second image transfer position where it faces the first image transfer body. The moving speed of each image carrier is equal to the moving speed of the second image transfer body. A period of time necessary for the surface of the first image transfer body to move from the first image transfer position to the second image transfer position is a natural number multiple of the period of speed variation occurring on the above surface.

摘要： In a control method of an optical disk unit, it is judged by performing a tentative tracking operation of an optical pickup in a constant region of an optical disk whether a tracking position of the optical pickup is located in a land or groove portion. After a correct tracking control condition is judged, an access operation according to command information is executed. The optical disk unit has a two-divisional light receiving element for receiving diffracted light caused by a pregroove and a prepit of the optical disk, and a differentiator for generating a difference signal between signals of this light receiving element. The optical disk unit further has an adder for generating a sum signal of the signals of the light receiving element, and a tracking signal selector for selecting the difference or sum signal when the tracking operation is performed in a pregroove or prepit region, respectively. An optical information recording medium and a method for recording and regenerating information by using this optical information recording medium are also shown.
