Abstract: An equalization apparatus and equalization method capable of reducing power consumption and minimizing degradation in reception performance even when changes occur in the reception environment. Channel response estimator 101 estimates a channel response from a reference signal and a received signal and outputs the result to control circuit 102. In addition, error corrector and detector 104 detects error from a soft decision value after equalization processing of the received signal in equalizer 103 and outputs an error detection signal to control circuit 102. Control circuit 102 detects a response having the largest delay and larger power than the power level threshold among the channel responses, determines the number of trellis states by making channel responses up to that channel response having the largest delay valid, determines the number of taps necessary for equalization processing in accordance with the number of trellis states determined, controls the power level threshold from an error detection result, and, in the same way, determines the number of taps in channel response estimator 101.

Abstract: A failure-data register unit receives failure data from a failure detecting module. Based on the failure data, a test-execution instructing unit instructs each module to execute access tests for the module accessed when the failure detecting module detected the failure. When a test-result receiving unit receives results of the access tests, a failure-location identifying unit identifies the failed module based on the results. A server-request control unit suspends server I/O while the access tests are performed.

Abstract: An electrophotographic image forming apparatus in which an electrostatic latent image is formed on a charged surface of a photoconductive drum. The image is developed with toner into a toner image and the toner image is transferred to a recording medium. A charging roller is in contact with the photoconductive drum and charges the photoconductive drum when the charging roller receives a high voltage. A detector detects a characteristic such as an electrical resistance of the charging roller and outputs a signal indicative of the characteristic. A charging power supply applies a high voltage to the charging roller, the voltage having a value in accordance with the signal. A neutralizing device neutralizes the charged surface of the photoconductive drum before the detector detects the characteristic of the charging roller but does not neutralize the charged surface of the photoconductive drum when the electrostatic latent image is being formed.

Abstract: A standardized user interface that can handle a system for cooperatively performing various tasks. Session contents display sections display information concerning sessions using display forms that are consonant with session types. The list of the session contents display sections is displayed by a session list display section, and information concerning the sessions can be displayed for each session. Since the session contents display sections detect the input of instructions for session operations, various types of sessions can be held using a standardized user interface. In addition, the generation and extinguishing of sessions can be performed by the session operation unit, and contents of the session information that is collectively managed by the session information update detecting unit can be reflected in the session contents display section of an individual terminal. Furthermore, all of the events initiated by a user can be handled by a control unit.

Abstract: An image retrieval method and apparatus for searching a plurality of images stored in an image file for a desired image are disclosed. When a designated image for designating an image to be retrieved is input, and its color is designated, the sizes and colors are compared between description information which stores the feature of each of regions obtained by dividing each of images to be searched stored in the image file, and feature data of the designated image. In this manner, the regions, which are determined to be included in the designated image, of image data are obtained, and the similarities between the obtained regions of image data and the designated image are calculated. Image data having higher similarities are read out from the image file, and are displayed while being sorted in the descending order from the highest similarity.
