摘要： A tandem-type color image forming apparatus forms a toner pattern and toner markers on an intermediate transfer member. Tone levels in the toner pattern vary in a sub scanning direction, and the toner markers which are a same color with the tone pattern each oppose, in a main scanning direction, a different one of the tone level portions in the toner pattern, each tone level portion representing a different one of the tone levels. Positions of the toner markers in the sub scanning direction are determined to detect densities in the toner pattern corresponding to the determined positions. Tone of image data is corrected in an image formation based on a relationship between the densities and the tone levels corresponding to the determined positions.

摘要： A clean environmental actuator is less in weight, height in transverse section and compact in construction, even with ensuring accurate position control and conformable to high speed operation and high acceleration/deceleration. Both a bed and a slider are stowed in an enclosure and packings are in T-slots in side walls of the bed to seal clearances between the bed and the enclosure. The enclosure is composed of an end bracket to cover one end of the bed, a motor bracket to cover another end of the bed, a pair of side coverings to enclose the side surfaces and tops of the side walls of the bed, a sealing panel to cover an upward opening between the side coverings, and a table covering to overlay an area of the sealing panel lying on the slider and side areas of the table bulging out from side edges of the sealing panel.

摘要： Techniques for unsupervised management of a question and answer (QA) forum include labeling of answers for quality purposes, and identification of experts. In a QA thread, a ranking of answers may include an initial labeling of the longest answer in each thread as the best answer. Such a labeling provides an initial point of reference. Then, in an iterative manner answerers are ranked using the labeling. The ranking of answerers allows selection of experts and poor or inexpert answerers. A label update is performed using the experts (and perhaps inexpert answerers) as input. The label update may be used to train a model, which may describe quality of answers in one or more QA threads and an indication of expert and inexpert answerers. The iterative process may be ended upon convergence or upon a maximum number of iterations.
