Abstract: A semiconductor acceleration sensor comprises: a frame having an opening inside thereof; flexible beams extending from the frame to the inside of the opening of the frame; a weight suspended from and supported by the beams so that the weight can freely move; piezoresistors to be mounted on the beams and to vary the resistance values in response to accelerations which work on the piezoresistors. The frame comprises damper plate portions, each of which covers a part of the opening spanning from a corner portion of two neighboring sides of the frame on the side of the opening to the inside of the opening, and each of which serves serve as a stopper to limit movement of the weight. The weight has corner portions which face the corner portions, respectively, and each of which is chamfered to have a shape of arc or a polygonal line consisting of at least three sides as seen in plan view. Thereby, the breaking strength of each stopper is increased, and hence a semiconductor acceleration sensor having superior shock resistance can be obtained.

Abstract: A document-managing-apparatus includes a storage unit which stores file-managing-information on a file of data constituting a document, which is a managing-target, and a storage unit which stores, by arranging in a particular order, document-managing-information on plural documents stored in the storage unit, position-information showing a display-position in a searching-screen of the display-unit being stored in the storage unit while related to the document when the storage unit receives a direction to search the document to display the documents in the arranged order in the searching-screen. When the apparatus receives a search refinement direction that narrows down the document from the plural documents, the apparatus searches the document, included within a previously set display-position in the display-positions shown by the position-information, from the plural documents. The apparatus displays only the document searched by a document-searching-unit on the searching-screen according to a direction to change the document display on the searching-screen.

Abstract: An object of the present invention is to realize almost the same transmission characteristic in all wavelengths at a transmission rate of 10 Gb/s or more. An optical transmitter 10 outputs WDM signal light multiplexed with signal light of a plurality of wavelengths toward an optical transmission line 12. The optical transmission line 12 comprises an optical transmission fiber 14, an optical repeating amplifier 16 and a dispersion compensating fiber 18. The gain characteristic of the optical repeating amplifier 16 is set so that the gain becomes the maximum at the effective zero dispersion wavelength of the optical transmission line 12 and that lowers inversely proportional to the distance from the effective zero dispersion wavelength. The whole optical transmission line 12 is set so that the peak power deviation between the effective zero dispersion wavelength &lgr;0 and the wavelength &lgr;1 or &lgr;n on both end becomes approximately 4 dB.
