A sensor having at least the sensor material and an optical waveguide is also provided. Furthermore, provided are a detection method for a bio-substance using the sensor material in which a change in tone is detected on the basis of swelling or shrinking of the stimulus-responsive high polymer gel, and a detection method for transmitting light using a sensor material in which transmitting light is detected on the basis of swelling or shrinking of the stimulus-responsive high polymer gel.

Abstract: Nozzle groups are arranged in a staggered pattern such that dead space does not occur. However, gaps are opened up between actuator units so that the actuator units can be joined to flow channel units. Further, piezoelectric elements are formed at each of the actuator units, and thus piezoelectric plates are consequently shorter. Therefore, when an inkjet recording head is lengthened, there is no need to form the piezoelectric elements by processing from a single long piezoelectric plate, implementation with a plurality of short piezoelectric plates is possible, and thus production yields do not deteriorate. Further, as the actuator units can be associated and arranged in a staggered pattern, an increase in width of the inkjet recording head can be minimized.

Abstract: Media removal apparatus having a stripper finger structure for separating the lead edge of an imaging media such as plain paper from a heated fuser roll and a stripper baffle for separating the portion of the imaging media beyond the lead edge of the imaging media from the heated fuser roll.

Abstract: A collection vessel 124 has a shutter 138 for opening and closing collection ports 136. A rotation shaft 140 of the shutter 138 is provided with an opening/closing piece 144. The opening/closing piece 144 abuts a protrusion on an image formation apparatus main unit and opens the shutter 138 largely so that a discharge section inserted into the collection port 136 does not abut. The collection port 136 is made a long hole so as to allow the discharge section to move. Further, the shutter 138 is formed integrally with a plurality of door parts 142 so as to open or close the collection ports 136 by one operation.

Abstract: For each page set contained in a hypertext and with reference to access history information, a hyperlink transition frequency acquiring unit calculates a transition frequency between the pages (i.e., a hyperlink) of the page set. An attribute extracting unit extracts an attribute from each page in the hypertext. In a correlation analyzing unit there is calculated a correlation between the transition frequency of the hyperlink and the attribute. When a predetermined page set is given as an object of analysis, the attribute extracting unit extracts an attribute, and in an attribute analyzing unit the attribute is compared with a multiple regression expression stored in a correlation data storing unit. The resulting correlation expression is displayed in a display unit. According to this configuration it is possible to show a cause of a problem involved in the page configuration of a hypertext system, present a remedial measure, and improve the page configuration easily.

Printer diagnostic data, which may include usage information and printer status information collected over a period of time, is parsed into individual components. The components are then input into a set of rules. Each rule compares each component with a corresponding reference value to generate a comparison result, correlates the comparison result with a set of actions including solutions, and if there is a correlation between the comparison result and a solution, providing the solution.

Abstract: An improved nanotip structure and method for forming the nanotip structure and a display system using the improved nanotip structure is described. The described nanotip is formed from a semiconductor having a crystalline structure such as gallium nitride. The crystalline structure preferably forms dislocations oriented in the direction of the nanotips. One method of forming the nanotip structure uses the relatively slow etching rates that occur around the dislocations compared to the faster etch rates that occur in other parts of the semiconductor structure. The slower etching around dislocations enables the formation of relatively high aspect ratio nanotips in the dislocation area.

Abstract: The present invention is a method and apparatus for improving the appearance of electronic images, and more specifically, to the efficient use of template rotation within a template matching process to enhance such images. The invention reduces the number of entries that are stored in a look up table by eliminating identical patterns that differ only by the angle at which they are output. The appropriate templates are then rotated it by the required angle for output subsequent to their retrieval from the lookup table.

Abstract: An input image is subjected to transform by a DCT transforming unit 20. A coefficient analyzing unit 30 compares a predetermined coefficient and coefficient data 120, and obtains low-frequency image data 150 of the input image by a high-frequency coefficient masking unit 50 and an inverse DCT unit 60 on the basis of a result of that comparison. A pixel subsampling unit 70 receives this low-frequency image data 150, and generates a subsampled image on the basis of the aforementioned result of comparison. The subsampled image and coefficient information are transmitted to a decoding side. A decoding apparatus decodes an image on the basis of the subsampled image and the coefficient information.

Communication is attempted to the network address, sequentially using each of a plurality of port numbers. If none of the plurality of port numbers is successful in initiating communication to the network address, communication to the network address is attempted using an LPR port number, sequentially using each of a plurality of LPR queue names.

Abstract: A method for color cast removal in a scanned image in L*a*b* space includes generating a first color cast correction curve for mapping L* to a first color correction, &Dgr;a*, (or &Dgr;b*) wherein the first correction curve provides a desired a* shift in midtone regions and is modulated as a function of L* such that black and white points are unaffected; for each pixel n in the scanned image, passing L*n through the first color cast correction curve for obtaining a value of &Dgr;a*n; and adding the value of &Dgr;a*n to the scanned image's original a*n component. To ensure that the color corrected a* remains within gamut, a second correction curve for applying a clipping factor to the mapped &Dgr;a* may be generated with the a*n passing through the second correction curve for obtaining a clipping factor Cn; and modifying the a*n value by Cn(&Dgr;a*n).
