Abstract: A matrix-addressed electroluminescent display panel has lower electrodes and back electrodes orthogonally provided with each other through a luminescent layer and the like. A passivation layer is formed on the back electrodes on an opposite side of the lower electrodes with respect to the back electrodes, and back electrode leading members are formed on the passivation layer on an opposite side of the back electrodes with respect to the passivation layer to be electrically connected to the back electrodes. The lower electrodes have ends arranged on one side of a substrate, and the back electrode leading members are formed to have ends arranged on the same side of the substrate as the ends of the lower electrodes. Accordingly, terminals of the lower and back electrodes can be arranged on one side of the substrate, thereby preventing increase of the size of the display panel.

Abstract: An analytical method capable of easily, rapidly, and accurately determining concentrations of a multi-component aqueous solution. Near-infrared spectra of a standard solution containing k components of known concentrations are measured n times within a range of 1,500 to 1,850 nm. A loading matrix of p columns by m rows and an intermediate matrix of k columns by m rows for an appointed factor number m are obtained from a response matrix of p columns by n rows consisting of p absorbance values of the respective spectra in a calibration stage and p absorbance values of a near-infrared spectrum within a wavelength range of 1,500 to 1,850 nm of a test liquid. The test liquid contains k components including pure water of unknown concentrations. The concentrations of the k components are determined from a group of absorbance values and the loading and intermediate matrices obtained in the calibration stage by a matrix operation in an prediction stage.

Abstract: An ID memory part memorizes an ID such as a telephone number that identifies a communicant, and a use frequency memory part memorizes a corresponding use frequency. When a communication apparatus takes a sending action, a writing part receives the ID from an addressee communicant and registers it in the ID memory part. In case the ID memory part does not have any unused memory region at this registering time, the least frequently used ID is deleted from the ID memory part and the memory region that becomes unused as the result registers the received ID. When a communication apparatus takes a receiving action, a comparison part receives the ID from an addresser communicant and sequentially compares the ID with each ID memorized in the ID memory part, and has the communication apparatus continue the receiving action only when a conformance is detected.

Abstract: A laser beam particle-detecting apparatus can automatically detect the position of minute particles on a substrate. A laser beam can be scanned across the substrate, and optical detectors can optically detect the laser beam after incidence with the substrate to define the position of any minute particles. Correction factors characteristic of the laser beam particle-detecting apparatus can be utilized to adjust the coordinates of the particle position, whereby any inaccuracies in the detecting apparatus can be compensated.

Abstract: An apparatus for detecting particles on a substrate incorporates a calibration system to correct any change in the angle of swing of a beam scanning mirror over a period of time. A pair of optical detectors can be positioned within the optical path between the scanning mirror and the substrate to provide a fixed reference point from which positional adjustments or calibrations can be made over the life of the instrument to eliminate any drifting of the positional signals of the actually detected particles on the substrate.
