Abstract: A non-reducing dielectric ceramic contains Ca, Zr and Ti as metallic elements and does not contain Pb. In a CuK&agr; X-ray diffraction pattern, the ratio of the maximum peak intensity of secondary crystal phases to the maximum peak intensity at 2&thgr;=25° to 35° of a perovskite primary crystal phase is about 12% or less, the secondary crystal phases including all the crystal phases other than the perovskite primary crystal phase. The non-reducing dielectric ceramic exhibits superior insulating resistance and dielectric loss after firing in a neutral or reducing atmosphere and high reliability in a high-temperature loading lifetime test and is useful for producing compact high-capacitance monolithic ceramic capacitors.

Abstract: A nonreducing dielectric ceramic contains a tungsten-bronze-type crystal phase including at least Ba, RE and Ti as elements, and a pyrochlore-type crystal phase including at least RE and Ti as elements, where RE is at least one rare-earth element. The relationship 0.10≦b/(a+b)≦0.90 is satisfied, where a is the maximum peak intensity assigned to the tungsten-bronze-type crystal phase and b is the maximum peak intensity assigned to the pyrochlore-type crystal phase determined by X-ray diffractometry. A ceramic electronic component includes an electronic component body composed of the nonreducing dielectric ceramic and a conductor in contact with the nonreducing dielectric ceramic.

Abstract: A nonreducing dielectric contains a main-component having a perovskite crystal phase and satisfying the formula (Ca1-a-b-cSraBabMgc)m(Zr1-w-x-y-zTiwMnxNiyHfz)O3 and a compound oxide represented by the formulae (Si, T)O2—MO—XO and (Si, T)O2—(Mn, M′)O—Al2O3. The ratio of the intensity of the maximum peak of a crystal phase not of the perovskite crystal phase to the intensity of the maximum peak assigned to the perovskite crystal phase appearing at 2&thgr;=25 to 35° is about 5% or less in a CuK&agr; X-ray diffraction pattern.

Abstract: A tool changer for machine tools is capable of transferring a tool transfer pot with a stroke smaller than the transfer distance of the tool transfer pot. The tool changer for a combined machining lathe includes a tool magazine having a multiplicity of tools and serving for transferring and indexing a next-process tool to a specified tool takeout position. A tool transfer mechanism transfers the next-process tool positioned in the tool takeout position or the tool delivery position to a tool changing position. A tool changing mechanism changes a process-completed tool loaded on a tool post body with the next-process tool positioned in the tool changing position. The tool transfer mechanism comprises a transfer arm pivotally disposed between the tool delivery position and the tool changing position. A tool transfer pot is coupled to a front-end portion of the transfer arm and serves to support the next-process tool.

Abstract: The digital image output apparatus comprises a digital image decoder (1a) for decoding encoded digital image data and outputting image data update information (V2); an image data transfer area control unit (7) for determining a portion of the image data which has been updated in encoding according to the image data update information (V2) and outputting a result of the determination (VCT); an image data transfer unit (2a) for transferring digital image data (V1A) from the digital image decoder (1a) to an LCD memory (4) on the basis of the output signal (VCT) from the image data transfer area control unit (7); and the LCD memory (4) for storing the digital image data (V1A). A low-power digital image output apparatus is implemented by transferring image data depending on whether the image data has been updated in encoding of a digital image.

Abstract: In order to reduce the power consumed by the circuit when the image data is transferred to a memory in a display means, a write region detecting means 8 is provided to detect the address region in the graphics memory 2 accessed for writing by the image data writing means 1, and only such data that is within the region including the addresses accessed by the writing means 1 is transferred to the memory 5 in the display means 4. The region including the accessed addresses may for example a rectangular region of from the minimum vertical direction address to the maximum vertical direction address Y among the accessed addresses, and from the minimum horizontal direction address to the maximum horizontal direction address among the accessed addresses.

Abstract: In an on screen display apparatus and an on-screen display method, the number of scanning lines of an input signal is detected. In accordance with the result of the detection, a vertical dot number of a character to be displayed is determined and font data is read from a memory device after adjusting a dot number of a blank portion of the font data. Hence, even if the number of the scanning lines changes, the number and positions of characters displayed in one screen remain constant.

Abstract: An immunological assay method, wherein the concentration of a substance to be assayed is calculated from a calibration curve, which is formed in the preparation of a reagent or in the assay of a sample based on parameter(s) determined in the preparation of the reagent, without the need of forming any additional calibration curve each time, is disclosed. By the immunological assay method of the present invention, the concentration of the substance to be assayed can be efficiently and discontinuously determined, when compared with conventional ones. The method of the present invention is particularly suitable for quantitatively determining an antigen or an antibody.
