Abstract: To realize image coding/decoding device that can compress an input multivalued image with high compression efficiency, the following measures are taken. First and second predictors predict the value of a target pixel based upon image data according to respective predetermined methods and respectively generate predicted value data. A run counter compares the image data and the predicted value data and if prediction hits and run continues to a pixel immediately before a count value of the run of the corresponding predictor is incremented by one. If there is no predictor the prediction of which hits and the runs of which continued to a pixel immediately before, the runs are sent to a selector together with the identification number of the predictor as run data. The selector selectively outputs a run value and an identification number or prediction error data from a prediction error calculator and outputs after the selector encodes it (them).

Abstract: The present invention provides an ink jet recording head that enables stable high-speed continuous printing, its manufacturing method and an ink jet recording device. A bubble generated in a common liquid chamber is moved to the side of an ink tank via a communicating port formed in a sufficient size and a supply passage. That is, a bubble generated inside a common liquid chamber is exhausted satisfactorily from the common liquid chamber by forming the communicating port in a shape which the bubble can pass, resulting in the supply of ink to the common liquid chamber and an individual passage (nozzle) prevented from being blocked by the bubble. As a result, even if high-speed continuous jetting (printing) is performed, stable printing is enabled.

Abstract: Software in a computer which accesses one or more software-intensive devices, such as a digital copier or printer, is organized in a set of layers. A device-dependent layer converts data transferred over various means, such as a modem or network, to a uniform data format. A protocol layer converts data from a particular accessed machine to a set of function calls. A system interface associated with the computer restricts a user of the computer to seeing only a subset of function calls, depending permissions granted to a particular user. The modular architecture of the software enables a system administrator to restrict a user to viewing machine status for a specific set of machines on a network, or limits the user to viewing only a certain set of functionalities from a particular machine.

Abstract: An image display medium provided with a pair of substrates both of which are substantially transparent, and a gas enclosed in space defined between them. Each of the pair of the substrates is provided with transparent electrodes (ITO). The space defined between the substrates encloses two types of particle groups having colors different from one another, have a negative charge polarity, and have different adhesiveness from each other with respect to the substrates. A white particle group having a positive polarity is further enclosed in the space. A voltage is applied to the electrodes 28 and 30 so as to apply an electric field determined in response to the types of particles to be transferred. Thus, a plurality of colors are selectively developed via the particle groups enclosed in the space for displaying different colors.

Abstract: Methods are disclosed for fabricating spring structures that minimize helical twisting by reducing or eliminating stress anisotropy in the thin films from which the springs are formed through manipulation of the fabrication process parameters and/or spring material compositions. In one embodiment, isotropic internal stress is achieved by manipulating the fabrication parameters (i.e., temperature, pressure, and electrical bias) during spring material film formation to generate the tensile or compressive stress at the saturation point of the spring material. Methods are also disclosed for tuning the saturation point through the use of high temperature or the incorporation of softening metals. In other embodiments, isotropic internal stress is generated through randomized deposition (e.g., pressure homogenization) or directed deposition techniques (e.g., biased sputtering, pulse sputtering, or long throw sputtering). Cluster tools are used to separate the deposition of release and spring materials.

Abstract: Personality traits displayed on a workbench are grouped into a character profile that is utilized in determining the personality and/or specific actions of a synthetic character. The personality traits are selectable by an operator from graduated dials. The personality traits may also be displayed in the form of selectable attributes or trait indicative behaviors that, when selected, are mapped into predetermined amounts of each trait in the character profile. The character profile is utilized to compute activation levels for primary behaviors, which are selected to influence or direct behavior of the synthetic character. Secondary behaviors are also selected, but discarded if conflicting with the selected primary behaviors. When behaviors are selected, the corresponding behaviors are translated into classes of ‘personality effectors’ that modulate the synthetic character's behavioral expression to reflect the desired set of traits.

Abstract: The present disclosure relates that by modifying chip die dicing methodology to a U-groove profile from a V-groove profile by modifying the second etch step to be a dry etch instead of a wet etch results in a direct cost savings by eliminating a more expensive process step, as well as the need for stripping the developed photoresist layer. Furthermore, going to a U-groove profile accomplishes additional indirect and greater cost savings resulting from increased process throughput, improved yield, and reduced metal layer defects.
