Abstract: The present invention provides an ink jet recording apparatus which can prevent problems such as image defects caused by shortage of ink, and decreases in the printing speed from occurring. When execution of a print job is instructed, a printing processing for the print job is started. The number of pixels which have been actually printed is added to a current pixel count C1, and it is determined whether or not the print job is finished. When it is determined that the print job is finished and the pixel count C1 exceeds a predetermined number of pixels X1, an ink supply unit is controlled so that ink of a predetermined proportion A (%) of the amount of ink used, which amount corresponds to the pixel count C1, is supplied to a sub-ink tank.

Determinations of failure modes of the toner sump are made and basic principles for replenishment are presented for implementation in a control system operable to enhance ink sump performance and to extend the ink sump lifetime.

Abstract: Opposing piezoelectric elements bordering a boundary between neighboring nozzle groups have point symmetry. Hence, even if a gap is opened up between actuator units due to necessity in assembly, rows of the nozzles are not offset. Accordingly, even a series of nozzle groups are combined in a conveyance direction of a recording medium, width of an inkjet recording head is not increased. Further, because the rows of nozzles are not offset, there is no requirement to offset discharge timings for each actuator unit, and output of image data does not become complex. Thus, lengthening can basically be implemented with two piezoelectric plates. Consequently, production yields can be improved.

Abstract: When an activity event conducted by user object in the work space is detected by the detection server according to the detection of the activity event ID tag, the activity event is saved for each object by the work space server and the individual activity history server while the activity event can be referred. When the thus saved activity event is traced referring to the other objects, the computer for displaying an overview can display the saved activity event by the display of the object.

Abstract: An architecture and manufacturing method for photosensitive chips, such as used in office equipment and digital cameras, involves creating grooves between chip areas in a wafer, and then placing a light-transmissive planar layer over the main surface of the wafer. The planar layer, which may be acrylic-based, creates a substantially planar surface over both the photosites in the chip areas and the grooves. The planar layer in turn supports one or more light-transmissive filtering layers. The arrangement avoids damage to the filtering layers when the wafer is diced along the grooves.

Abstract: Methods and systems for romanizing Chinese ideograms allow a user to create a personalized spelling dictionary that converts a user's desired roman-alphabet spelling to an equivalent Chinese character. A phonetic combination from a standard Chinese dialect is selected. The user defines a roman alphabet equivalent of the selected phonetic combination that fits the way the user pronounces the phonetic combination in the user's own dialect or idiolect.

Abstract: A method includes forming a plurality of test patches in an array of orthogonal rows. The test patches are formed by using at least one printhead in an imaging machine.

Abstract: During the operation of an electronic system, such as a document processing system, machine and job data of the electronic system are collected by a diagnostic system for automated diagnosis or prognosis. Optionally, machine data and population based data are acquired from a database or server.

Based on the initial diagnosis, a determination is made whether a remote transmission is needed. If so, the data is sent via a distributed network to a remote diagnostic system for analysis. At least part of the collected machine data may be a signature waveform of a part of the electronic system. In such a case, at least the analysis by the remote diagnostic system includes signature analysis of the waveform. Based on the analysis of the data by the remote diagnostic system, a communication is sent.
