Abstract: The present invention provides an ink jet recording head in which the degree of freedom in the design of the arranged position of an electric signal input-output terminal is enhanced, its manufacturing method and an ink jet recording device, the invention is characterized as follows. The ink jet recording head is formed by laminating a heater element substrate in which a heater element and others are arranged and a passage substrate in which nozzles and others are formed. When the nozzles and others are formed by etching in the passage substrate, a cut-out portion for exposing an electric signal input-output terminal of the heater element substrate is also formed. Therefore, the degree of freedom in the design of the shape and the position of the cut-out portion in the head chip is enhanced.

Abstract: A method of fabricating and a wafer having a plurality of photosensor Arrays thereon. And, a method of testing the wafer before the wafer is diced and assembled to form a Silicon photosensor Array which may be combined with other like photosensor arrays to form a full page width image sensor bar. The invention allows checking of every V-groove on every chip. An implanted or diffused region is placed across the V-groove, with electrical connections on both ends of the diffusion. If the V-groove is formed, the diffused region will be broken and the electrical path will be open. A deeper diffusion can be also used to check for incomplete V-grooves. If one end of the electrical path is tied to an existing I/O pad on the chip and the other end to ground, this path will have no effect on the input resistance if the V-groove is formed. There will be a small, but acceptable, increase in input capacitance.

Abstract: There will be provided an image processing apparatus made available irrespective of the mechanism and the like of an output device to be connected thereto. A configuration control unit sets connection patterns and output systems of a first to a fourth output control units depending upon configuration, a connecting method and image data to be inputted of an output device. Also, a processing order control unit is interlocked with this configuration control unit, and constitutes data for each band from image data inputted so as to have sequence responsive to configuration of a first to a fourth rendering processors controlled by the configuration control unit. Thus, data for each band is controlled so as to be inputted into the first to fourth rendering processors in accordance with the processing order. In this way, it is possible to cope with any case where various output devices are connected.

Abstract: A color conversion table designed to produce 0% under-color removal and a 100% under-color removal TRC are configured as a matched pair and are used to render an image from fuzzy detected color signals, including providing variable under-color removal to obtain fuzzy black conversion. The output of the color conversion table and the TRC are multiplied by a weighted value which depends on a value of a received neutral tag. The weighted outputs of the color conversion table and TRC are added such that a varying weighted output is generated. The generated output is used in image rendering to produce a smooth transition from a full color to monochrome, where variable amounts of under-color removal are obtained using the color correction table and TRC.

Abstract: In a system where two types of data are to be compressed using hierarchical vector quantization (HVQ), it would be typical for there to be two compression tables, one optimized for each type of data. A boundary between the two types may occur within a block to be compressed. In this case, a third table, optimized for a block having both types of data, is used.

Abstract: Widgets are annotated with freeform digital ink. Rather than annotating the data displayed by widgets, annotations are made “on” the widgets themselves and stored in relation to the application and/or window they are associated with. These annotations allow users to interact with widgets without having to keep a separate hardcopy set of notes or instructions explaining how to use the widgets.

Abstract: A method and apparatus prevents banding defects caused by drop mass variations in an ink jet printer. The ink jet printer uses different pre-pulse sequences for drop ejection depending on print head temperature. Each of the different pre-pulse sequences is associated with a corresponding temperature range. Boundaries between adjacent temperature ranges are separated by critical temperatures. A determination is made as to whether a change in the print head temperature constitutes, or is part of, a temperature change that exceeds a predetermined threshold change amount, prior to determining whether to change the pre-pulse sequence.

Abstract: A surface emitting semiconductor laser that is easy to manufacture and has a high-intensity fundamental lateral mode optical output power. The surface emitting semiconductor laser has a semiconductor substrate on which are sequentially laminated a lower n-type DBR layer, an active layer region, an upper p-type DBR layer, a p-side electrode that is an upper layer of the upper n-type DBR layer and functions as an upper electrode provided with an aperture that forms an emission region for a laser beam, and a current confinement portion formed by oxidization. On the basis of the reflectance of a cavity in a region corresponding to the p-side electrode, a metal aperture diameter (Wmetal) of the aperture and a diameter (Woxide) of the current confinement portion are determined such that the difference between an optical loss of a cavity in a higher-order lateral mode of a laser beam and an optical loss of a cavity in a fundamental lateral mode of a laser beam becomes larger.

Abstract: A satisfactory bonding is implemented at low cost. In a step, a resin layer is formed on a bonding surface side of a silicon wafer on which portion are formed electro-thermal transducers. In a later step, the silicon wafer and another silicon wafer are aligned and fixed temporarily, then the atmosphere is set at a pressure of 10−3 mbar or lower and the temperature is set at 300° C. or higher, and voltage is applied across the both wafers while pressure is applied to the wafers. When the value of an electric current flowing across the wafers has reached a level of a certain current value or lower, the application of the voltage is stopped and the atmosphere is opened to the atmospheric pressure while reducing the temperature.

Abstract: A system for generating a warped contone image that compensates for beam scan trajectory distortions. The system includes an image buffer for storing a portion of a received contone image. An interpolation coefficient generator provides interpolation coefficients associated with a warped pixel within the warped contone image in response to an input identifying the warped pixel. A pixel interpolator is coupled to the image buffer and the interpolation coefficient generator and provides an output signal that identifies the warped pixel within the warped contone image. The pixel interpolator further retrieves pixels from the contone image stored in the image buffer using the interpolation coefficients and generates the warped pixel by combining the retrieved pixels into a single pixel value.

Abstract: Efficient methods are disclosed for fabricating metal plated spring structures in which the metal is plated onto the spring structure after release. A conductive release layer is deposited on a substrate and a spring metal layer is then formed thereon. A first mask is then used to form a spring metal finger, but etching is stopped before the release layer is entirely removed. A second mask is then deposited that defines a release window used to remove a portion of the release layer and release a free end of the spring metal finger. The second mask is also used to plate at least some portions of the free end of the finger and selected structures exposed through the second mask. Remaining portions of the release layer are utilized as electrodes during electroplating. The resulting spring structure includes plated metal on both upper and lower surfaces of the finger.

Abstract: A method for calibrating a VCO within a phase locked loop circuit is disclosed. First, a DAC output voltage is set to its minimum, and a counter M is adjusted until a comparator is its threshold voltage. Next, the DAC is set to another voltage, and counter M is again adjusted to the comparator threshold. This process is repeated for as many steps as desired. When the phase locked loop circuit requests an instantaneous frequency, an interpolation of the requested frequency against the curve created by the above-described method gives the value required by the DAC.
