Abstract: 5 n7 Disclosed is a method and apparatus for mixing internally generated or stored video with an external video and driving an LCD display device. External video is clocked into a dual port external frame store. Internal video is either internally generated or read from an internal mass store device and stored in an internal frame store and in a preferred embodiment, the internal video data includes an embedded code which serves to select on a pixel by pixel basis the appropriate frame store signal, either external or internal for display on the LCD panel. By adjusting the start number on row and column counters for reading out data from the external frame store, panning of an external video image can be accomplished. By repeating the readout of the external frame store selectively, a "zoom" of the image can be provided to an LCD display device. By reversing either the direction in which the external video is stored in the frame store or the direction in which columns of information are read out, the displayed image can be reversed permitting rear projection of an accurate image.

Abstract: A hierarchical encoding/decoding apparatus corresponds to imaging systems having mutually different resolutions. The apparatus constitutes an entire band width apparatus by using two encoding/decoding devices each for a low band width processing. In the low band width, the apparatus sub-samples a signal only in a vertical direction, while the apparatus sub-samples the signal only in a horizontal direction in a high band width. Accordingly, since sampling numbers are the same each other both in the low and high band widths, a processing amount in the high band width becomes similar to a processing amount in the low band width.

Abstract: Two addresses of an integrated circuit are selected to define a portion of the die which is functional and the portion of the die which will not be used. An input structure for addresses, which may be added to part of the electrostatic discharge (ESD) input structure of a pin, allows an address signal to be set to a predetermined logic level and to not be bonded out to the package. Additionally, another input structure allows the mapping of a signal pin to be changed. The function of a pin may need to be changed to accommodate a pinout for a different density device. This is useful when a die is put into a smaller density device package which has a pin out that does not accommodate the die. In this way, partially functional die that previously were discarded may be utilized, thereby recouping potential losses during manufacturing.

Abstract: A comb-shaped electrode and a planar electrode are formed on a surface and a bottom face of a substrate. Then, a DC voltage on which a pulse voltage is superimposed is applied to the electrodes using a DC power source and a pulse power source so as to apply a DC electric field on which a pulse electric field is superimposed to the substrate. As a result, periodic domain-inverted regions are formed by applying even a small pulse electric field. Since the applied electric field is highly uniform in a face of the substrate, the domain-inverted regions having a uniform periodic structure are formed. Alternatively, after the comb-shaped electrode is covered with an insulating film, the pulse voltage is applied to the electrodes using the pulse power source so as to apply the pulse electric field to the substrate. As a result, since movement of free charges in the surface of a crystal is restrained so as to inhibit the spread of domain inversion in a horizontal direction, a uniform short-periodic domain-inverted structure is formed. According to the present invention, deep short-periodic domain-inverted regions are uniformly formed over a large area of the substrate. As a result, an optical wavelength conversion device having a short wavelength with high efficiency can be manufactured.

Abstract: A process for preparing a solidified material containing a coal ash comprises a first step of mixing the coal ash with a calcium compound to obtain a mixture, a second step of molding the mixture to obtain a molded article, and a third step of subjecting the molded article obtained in the second step to a hydrothermal treatment at a temperature of 120°C or more under a high pressure. In the first step, 40 to 95 parts by weight of the coal ash is mixed with 60 to 5 parts by weight of the calcium compound, and the coal ash to be used has a bulk density of 0.8 g/cm³ or more, an average particle diameter of 5 to 40 µm and an aluminum content of 35% by weight or less in terms of Al₂O₃. By the use of a blowing agent or the like, it is also possible to obtain a porous light-weight solid. In consequence, there can be obtained the solid containing the coal ash and having a high mixing ratio of the coal ash, an excellent dimensional stability to water, a high strength and a decreased unevenness of the strength, and this kind of solid can be applied to many fields as building materials, construction materials, artificial aggregates and the like. Furthermore, a laminated solid having not only the above-mentioned characteristics but also weight reduction properties can also be obtained, and this solid can be suitably applied to building materials such as panels, blocks, bricks and boards for accoustic use, artificial light-weight aggregates and the like. Accordingly, the coal ash which is an industrial waste can be effectively utilized in large quantities, so that the conventional hard and troublesome problem of treating the coal ash can be solved or relieved.

Abstract: In the case where the free area of a memory (170) in a printer is insufficient when one-page's image data from a host computer (110) are converted into intermediate codes so as to be stored into the memory (170), the intermediate codes are converted into real image data, that is, bit map data, and the real image data are compressed and stored in the memory. If compressibility is insufficient in spite of the compression of the real image data, the real image data are converted into data of a data format higher in compressibility and then the converted data are compressed. A plurality of data formats different in compressibility are prepared so that an optimum data format is selected. Further, when the number of times of compression carried out to the one page's image data or the time required for compression is larger than a threshold, a user is informed of this fact and given a proposal to extend the memory (170).

Abstract: The present invention provides an optical parametric circuit for separating four-wave-mixing wave(s) (FWM wave(s)) from signal wave(s) and/or pump waves without using a wavelength filtering device, and optical circuits using the same. The optical parametric circuit of the present invention is made by connecting two output ports of a 2x2 optical directional coupler (20) to a nonlinear optical medium (12) via dispersive optical media (21, 22), each of which has a specific length and a specific propagation constant. By inputting signal waves having carrier angular frequencies ω Sj  (j=1, 2, ..N) and pump waves having carrier angular frequencies ω P1 , ω P2  into the first input port (20a) of the optical directional coupler, the FWM waves, generated in the nonlinear optical medium, having carrier angular frequencies of ω f  j (=ω P1 +ω P2 -ω S ) are output from the second input port (20b) of the optical directional coupler. By inputting the signal waves and the pump waves from different input ports of the directional coupler, it is possible to separate amplified signal waves and the FWM waves from the pump waves. By adjusting the lengths and the propagation constants of the dispersive optical media, the amplified signal waves are separated from the pump waves and the FWM wave. The optical parametric circuit is used for wavelength conversion of optical signals, parametric amplification of optical signals, optical phase conjugation (spectral inversion) and for all-optical switching and for optical circuits using the same, for example, optical logic circuits, optical time-division multi/demultiplexers and/or optical sampling circuits.
