Abstract: A developing apparatus has a developer support 2 to which a developing bias VB with an AC component VAC superimposed on a DC component is applied for visualizing a latent image on a latent image support 1 in a dual component developer G supported on the developer support 2. It includes a use history estimation 5 for estimating a use history of the developer G or a use history detection device 6 for detecting a use history of the developer G and a developing bias power supply 3 provided with a peak-to-peak voltage changing device 4 for changing a peak-to-peak voltage Vp-p of the AC component VAC based on information from the use history estimation device 5 or the use history detection means 6.

Abstract: A word shape token-based document classification system prepares a plurality of sets of training data degraded by image quality and selects the optimum training data set by examining scores from a relevance measurement. The system achieves high accuracy from a wide range of image quality.

Abstract: A system and method for pipelined data processing emulates multi-tasking pipelined data processing in a single tasking environment. A host application running in the single tasking environment creates a pipeline of linked data processing tasks to process data from a data source and to provide the processed data to the host application. As each data processing task of the pipeline is created, the task calls an external procedure to obtain header data indicative of the data to be received by the task. Each task alters the obtained header data to reflect the data processing operation to be performed by the task, then the task creates an external procedure callable by other tasks or the host application. The external procedure provides the processed header data from within a task to the calling task or host application. After all tasks of the pipeline are created the host application invokes the pipeline to obtain processed data from the pipeline.

Abstract: A method and device for describing a complex color raster image as a collection of objects in a hierarchical and device independent format. The purpose of structured imaging (SI) is to expand the scope of a raster image to a collection of individually manipulable component objects. An SI is a hierarchical description of a single output image raster which may be used as one component of a page in a structured document. Objects contributing to the output raster may originate from text, graphics, other rasters or a combination thereof, and all maintain their heritage for selectability and modification. The SI describes not only the source data but also the image processing operations required for rendering the output raster. SI technology supports re-editability, customization and enhancement, automatic image assembly and high performance imaging. Thus, such a model has implications not only in an image editing and processing arena, but also in the filing and printing services used for image handling.

The fluorescent printer head includes dot-like anodes constituting a luminous area, control electrodes having apertures formed at positions corresponding to the dot-like anodes, and at least one filamentary cathode stretched above the control electrode extending along the middle portion of the luminous area.

Abstract: A dynamic memory device comprises a dynamic memory circuit, an input buffer circuit for temporarily storing data each time it is received from a source external to the device; an output buffer circuit for temporarily storing data each time it is read out from the dynamic memory circuit and for outputting the stored data in a unit of a predetermined number of words each time a request for reading is made; and a control circuit for controlling the input and output buffer circuits so that reading and writing operations can be performed independently of a refreshing operation.

Abstract: An electronic device of the element row type, and a wiring method of its electrode pattern, is characterized by the disposition of a plurality of the elements being arranged in a longitudinal array which is divided into a plurality of blocks. A pair of driver devices are employed to drive the elements, and wiring patterns interconnect the elements to the driver devices. In accordance with the present invention, the wiring patterns include first portions which extend in a direction perpendicular to the longitudinal extent of the element array, and second portions which extend parallel to the longitudinal extent of the element array, with the parallel portions defining substantially the same width dimension regions, and wherein further, such width regions are overlapped with respect to each other such that the overall width of the wiring pattern for the electronic device may be substantially reduced as compared to those of prior art devices whereby miniaturization of the electronic device may be achieved.

Abstract: An image sensor comprises a plurality of photoelectric converting elements of the sandwich type arranged on a substrate in which a photoelectric conversion layer is sandwiched between upper and lower electrodes and a light shielding film having a window for controlling the quantity of incident light is formed so as to correspond to each of the photoelectric converting elements, wherein, noting the fact that a photoelectric current can be dervied from a wider area than the actual area of a photoelectric converting region, an overlapped region of lower and upper electrodes in each of the photoelectric converting elements is made smaller in area than that of the window.

Abstract: A method for the formation of a multi-nozzle ink jet is herein disclosed. In this method a single crystal silicon plate is masked and impurities are diffused upon its surface, creating regions of echant resistance. A second single crystal silicon plate is then grown onto the first, and is masked and etched. Due to the unisotropic etching properties of single crystal silicon plates, a groove is formed in the second plate, and a plurality of nozzles is formed in the first plate. This process yields a multi-nozzle ink jet of greater overall strength and utility, while eliminating the waste due to etching run common in the manufacture of conventional ink jets.
