    摘要： A speech synthesis method subjects a reference speech signal to windowing to extract an aperiodic speech pitch wave from the reference speech signal. A linear prediction coefficient is generated by subjecting the reference speech signal to a linear prediction analysis. The aperiodic speech pitch wave is subjected to inverse-filtering based on the linear prediction coefficient to produce a residual pitch wave. Information regarding the residual pitch wave is stored as information of a speech synthesis unit and a voiced period in the storage. The speech is then synthesized using the information of the speech synthesis unit.

    摘要： A pressure sensor includes a first diaphragm having a first surface receiving pressure, a first thermal detection section located opposite a central section of the first diaphragm, and a second thermal detection section having little displacement by pressure, and located opposite the first diaphragm The pressure sensor amplifies and outputs a difference between the first thermal detection section for pressure measurement and the second thermal detection section for reference output. Since the diaphragm to which the second thermal detection section is opposed is equal in thickness to the diaphragm to which the first thermal detection section is opposed, pressure can be accurately measured relative to a sudden change in atmospheric temperature.

    摘要： A pressure transmitter apparatus having a unitary body portion, separate diaphragms and flange elements and disposed within the body, a first and second normally vertical pressure passage. The first and second pressure passageways communicate respectively between first and second pressure openings extending normally horizontally through the body portion, and a transducer mounting element. The mounting element, coupled to the body portion and located above the pressure passageways, mounts a transducer that generates a differential pressure signal. One or a pair of diaphragm elements are configured to form first and second process diaphragms, closing first and second pressure openings. The flange element overlies the diaphragm element and is removably and replaceably secured to the body portion. The pressure transmitter also includes a flame retardation element that is disposed within at least one of the pressure passageways, and an overrange protection element, integrally arranged with the unitary body portion, that protects the transducer from overrange pressure fluctuations. Special flange plane geometries optimize size and sensitivity of isolation diaphragms.

    摘要： A pressure differential measuring transducer has measuring membranes arranged side by side on one side of a membrane disk and a common fluid space allocated to them. To obtain a measured electric quantity which is proportional to a pressure difference and is independent of changes in static pressure with such a measuring transducer, a part of the membrane disk carrying a first measuring membrane is accommodated from the side in the interior of a tube with a seal, said tube being acted upon by a first pressure at its one end and at its other open end. Another part of the membrane disk having a second measuring membrane extends into an interior space of a container adjacent to the tube to which a second pressure can be applied.
