Abstract: A channel wafer has a plurality of nozzle flow channels and a common ink reservoir. Pits communicating with the ink reservoir from above heating elements are formed in a polyimide layer on a heater wafer. Each of the pits has a throttled portion in the rear of the heating element and the terminal of a nozzle flow channel is situated on the throttled portion so as to form the minimum sectional area portion of the flow channel. Stable ink discharge characteristics are attained by means of the flow channel resistance of the minimum sectional area portion and bubble pressure is prevented from being relieved toward the ink reservoir. The pressure propagated to the ink reservoir is made to attenuate internally, so that no crosstalk is produced.

Abstract: A method of providing a polymeric film with optical anisotropy by applying a polarized light to a polymeric film is disclosed. In the method, a photoisomerizable group or a photoisomerizable molecule has a T (thermal) type photochromic property capable of being isomerized by a thermal back reaction after the isomerization by light. The method includes two successive steps, that is, a step of applying a polarized light to the polymeric film and a step of shutting off a polarized light and leaving the film as it is, and controls the temperature of the polymeric film for enhancing the orientation of the photoisomerizable group or the photoisomerizable molecule induced by the thermal back reaction. An apparatus for practicing the method and an optical anisotropic medium having the polymeric film with high optical anisotropy obtained by the method are also provided.

Abstract: A marking apparatus is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Marking material, such as ink, toner, etc., is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. At sufficient velocity, and with appropriate marking material, the marking material may be kinetically fused to the substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

Abstract: A graphical user interface widget includes a vertically-oriented slider portion. The slider portion includes a slider pointer that indicates a current value of the slider and a slider bar that indicates the default value of the slider. The bottom and top edges of the slider portion are labeled with the extreme values of the range for the variable associated with the slider portion. The slider pointer divides the slider portion into two subportions. An appearance of a bottom subportion of the slider portion is altered to reflect the value currently indicated by the slider pointer relative to the extreme values of the range represented by the slider. A numerical portion can be provided along with the slider portion. The numeral portion includes a value display portion and a pair of buttons that are used to increase or decrease the numerical value in the value display portion.

Abstract: A composite higher resolution image of an object can be obtained by combining or patching together multiple low-resolution camera images to form a composite image having a higher resolution. Each low-resolution camera image represents a subsection of an object (also referred to as “object subsection”) to be scanned. For example, each subsection may represent a quadrant of a document page. With the use of a periscope, the image visible to the camera can be shifted to capture images of the various object subsections. Mosaicing techniques are used to combine these camera images into a composite image of the object. This approach to scanning improves the resolution of documents scanned while using existing low cost video cameras.

Abstract: An operational sequence including a cleaning of a processing device shifting to the standby state in the process of shifting from a printing operation to a standby state of a liquid electro-photographic device of a tandem type is performed well. A processing device has a squeeze roller for performing removal of residual liquid developer from an image formed on a photoconductive belt 2 and for forming an image into a film and is removed in order that the squeeze roller 6 shifts from the state having a clearance from the photoconductive belt 2 to the state being pressed against the photoconductive belt 2 for performing a removal of the liquid developer remaining on the squeeze roller 6 to the photoconductive belt 2 in sequence when the image forming operation is finished after cleaning the liquid developer adhered on the squeeze roller 6, and the removal proceeds sequentially from a processing device on a downstream side of a traveling direction of the photoconductive belt 2.

Abstract: A method of outputting a recording medium on which forgery-inhibited data of a certificate of residence, securities, or the like which is obtained through a communication network such as a computer network and is inhibited to be forged by copying is printed directly from a printer without using a copy forgery preventing sheet. A recording medium outputting system of the invention is constructed by connecting a LAN having a DB server managing transmission/reception of data to/from a database disposed in a city office or the like, and a number of LANs each having a terminal and a printer installed in stores such as convenience stores via a communication line and the internet.

Abstract: Techniques for determining user types based on multi-modal clustering are provided. The topology, content and usage of a document collection or web site is determined. The user paths are identified using longest repeating subsequence techniques and a multi-modal information need vector is determined for each significant user path. Multi-modal vectors for each document in the significant path, content, uniform resource locators, inlink and outlink multi-modal vectors are determined and combined based on path position and access frequency. Multi-modal clustering is performed based on a multi-modal similarity function and a specified measure of similarity using a type of multi-modal clustering such as K-means or wavefront clustering. The identified clusters may be further analyzed based on changes to the weighting of the corresponding content, url, inlinks and outlinks multi-modal feature vectors.

Abstract: A feedback mechanism usable with graphical user interface systems that do not have a cursor improves the usefulness of such graphical user interfaces. Locating, identifying and/or selecting hyperlink targets or active areas within a displayed image map or within a Web page is facilitated by providing distinctions to the hyperlink targets or active areas or by providing other locational indicators for a designated time period in response to a single user gesture. The distinctions or locational indicators may be provided in combination with other distinctions or locational indicators to further aid the hyperlink target or active area location, identification and/or selection process. After a designated time period expires, the distinctions, locational indicators, or their combination, are removed from the display without any additional user gesture. This increases the efficiency and convenience of locating, identifying and/or selecting hyperlink targets or active areas in a graphical user interface system.

Abstract: A method of creating an authenticatable sheet of material, includes measuring at least one physical property of the sheet of material; marking an edge of the sheet of material with indicia arranged to form a unique code identifying the sheet of material, wherein the sheet of material includes a first surface, a second surface disposed opposite the first surface and an edge extending between the first surface and the second surface and peripherally about the sheet of material; and recording the measured physical property in a measure database indexed by the edge code. To verify the validity of a sheet of material, the edge code is read, the same physical property is measured and the measured value is compared with the previously stored value extracted from the measure database. If the two are substantially equal, the sheet of material is authentic.
