Patent JP-H0377968-B2 (JP)
IPC: H01S3/06
Filed: 1983-08-08
Abstract: An optical fiber bidirectional amplifier includes a pair of small diameter optical fibers (12a, 12b), arranged in a side- by-side configuration, the first fiber (12a) providing a pumping source and the second fiber (12b) doped with a material which will lase at the frequency of the signal to be amplified. The signal to be amplified propagates through the second fiber (12b) to stimulate emission of coherent light from the lasing material, resulting in amplification of the signal. The refractive index of the first and second fibers (12a, 12b) is substantially identical, but the coupling characteristic provided by the geometrical relationship between the pair of fibers (12a, 12b) yields a wavelength dependent coupling efficiency. Specifically, the coupling efficiency at the wave- lenght of the pumping source is relatively high, while the coupling efficiency at the wavelength of the signal to be amplified is relatively low. Thus, the pumping illumination is coupled from the first fiber (12a) to the second fiber (12b) to stimulate the doping material in the second fiber (12b), while the signal to be amplified remains relatively uncoupled, and is amplified by the coherent light emitted by the lasing material.

Abstract: Energy normalization in speech synthesis systems is achieved by a look-ahead adaptive normalization procedure, wherein energy is adaptively tracked, and the adaptive energy-tracking value is used to normalize a much earlier frame's energy value. In another aspect, silence suppression in speech synthesis systems is achieved by detecting and processing only segments of voice activity. A segment is classified as "speech" if the energy of the signal is greater than an adaptively adjusted threshold. The adaptively adjusted threshold is preferably defined as the maximum of scaled values of two separate envelope parameters, which both track the variation in energy over the sequence of frames of speech data. One contour is a slow-rising fast-falling value, which is updated only during unvoiced speech frames, and therefore tracks a lower envelope of the energy contour. This parameter in effect tracks an ambient noise level. The other parameter is a fast-rising slow-falling parameter, which is updated only during voiced speech frames, and thus tracks an upper envelope of the energy contour. (This in effect tracks the average speech level.)

Abstract: The invention relates to a tape suitable for use in fuel cells, to an electrode suitable for use in a fuel cell, to a method for sintering an electrode of this type and to a fuel cell which contains an electrode of this type. The invention provides a tape with improved properties, which is characterised in that said tape contains LiCoO2. A tape of this type can be produced in a manner known per se using LiCoO2 and a binder. Expediently, a plasticiser and/or dispersant and/or anti-foam is used together with the binder, as is known per se for the preparation of tapes. Platelets can be produced from such a tape, which platelets can then be sintered, optionally after stack-ing. Sintering is expediently carried out in an atmosphere consisting of 60 to 80% air and 40 to 20% carbon dioxide, in particular 68 to 72% air and 28 to 32% carbon dioxide. A suitable temperature programme is chosen for sintering. Good results are obtained by heating to 250 DEG C at a heating rate of 100 DEG C per hour, then heating to 450 DEG C at a heating rate of 50 DEG C per hour, then heating at a heating rate of 100 DEG C per hour to the desired sintering temperature of 800 to 1000 DEG C and finally, after sintering, cooling to room temperature at a rate of 100 DEG C per hour. Of course, the invention also relates to fuel cells which are provided with a material according to the invention. <IMAGE>

Abstract: PURPOSE:To decide a fact that a pitch exists in one of a positive or negative signal and to extract the pitch in a voice period by driving a signal into a positive signal part and a negative signal part by a positive/negative deciding part, binarizing the positive signal or the negative signal in accordance with an energy level of the signal is large or small by a binarizing part, and deriving an auto-correlation of each signal which is binarized. CONSTITUTION:A signal from a voice input terminal 1 passes through an LPF 2 and inputted to a positive/negative deciding part 3, a waveform peak level of every unit time of the signal is detected, and thereafter, the signal is divided into a positive signal part and a negative signal part, and the positive signal part is inputted to a binarizing part 4. In this binarizing part 4, a prescribed level of the waveform peak level is set to a clip level, and binarized by determining '1'.'0'. Subsequently, a correlation of each signal which is binarized is derived by a correlation arithmetic part 5, and inputted to a pitch existence deciding part 6. Next, when the correlation exists in one of the positive signal part and the negative signal part, it is decided that a pitch exists by the deciding part, the pitch is extracted in a voice section, and an erroneous extraction of the pitch in other signal section than the voice section is decreased.

Abstract: A method and device for removing solid or liquid particles contained in suspension in a gas stream by an electric field, wherein the gas stream flow is directed past ion sources which simultaneously act as field electrodes. The suspended particles are thereby changed in a bipolar manner, such that approximately half of the particles are positively charged and the other half negatively charged, and are forced by the electric field to migrate across the gas stream into a preferred neutralization zone where they are concentrated, discharged, partially agglomerated and coagulated. Subsequently, the particle-enriched and particle-depleted partial gas stream thus formed are separated and treated further in accordance with operating requirements. Thereby the remaining gas stream maximally loaded with particles is fed into a particle-removal device where their withdrawal occurs. The device results in a considerable reduction in the gas volume carried along up to the fine-cleaning stage, and a decrease in cost of the electrofilter by a factor of two or more.

Abstract: A method for producing expandable thermoplastic microspheres by polymerisation in a reaction vessel of an ethylenically unsaturated monomer or a mixture of monomers in an aqueous suspension in the presence of a condensed propellant. In the method, the monomer or monomer mixture is suspended in the aqueous medium in the presence of a powder stabiliser which consists of a salt or hydroxide of any of the metals Ca, Mg, Ba, Fe, Zn, Ni or Mn. The powder stabiliser is insoluble in the aqueous medium at the pH the aqueous medium has at the polymerisation. The aqueous medium may also contain a co-stabiliser. The method further comprises the step of washing off the powder stabiliser from the microspheres after the polymerisation by lowering the pH of the aqueous medium by the addition of acid. Alternatively, amphoteric hydroxides can also be dissolved by a pH increase. The invention also relates to microspheres produced according to the method of the invention, and to the use thereof.
