Patent JP-H0137194-B2 (JP)
IPC: C02F1/20
Filed: 1984-09-26
Abstract: The problem of rising sludge in biological wastewater treatment secondary clarifiers is overcome by minimizing entrainment of nitrogen gas with mixed liquor entering the transfer pipe to the clarifier such that the level of dissolved nitrogen in the biomass settling in the clarifier remains less than that in equilibrium with nitrogen gas at the pressure prevailing in the biomass. This invention is most efficacious in cases where soluble oxides of nitrogen are present and are reduced by the biomass to elemental nitrogen. In accordance with one described embodiment the excess nitrogen is removed by degassing of the mixed liquor in the effluent pit of the system by deepening and widening the usual pit in such manner that the rate of descent of mixed liquor therein to a discharge outlet is less than 0.4 feet per second and the depth is greater than 4 feet, thus permitting the gas-containing macrobubbles to rise to the surface of the pit where these are degassed. The mixed liquor thus freed of macrobubbles is then passed through a hydraulic pressure zone enroute to the clarifier in which pressure zone the nuclei microbubbles are caused to dissolve.

Abstract: A stereo panoramic view is provided through the use of multiple virtual optical centers. A reflective polyhedral element (40), such as a pyramid, redirects the field of view of each camera in a first set of cameras (52,54,56,58) to form a group of substantially co-located virtual optical centers (90) at a first location within the pyramid. The pyramid also redirects the field of view of each camera in a second set of cameras to form a group of substantially co-located virtual optical centers at a second location within the pyramid. Panoramic images from the first and second virtual optical centers provide a stereo panoramic view when one panoramic image is provided to a user's left eye and the other panoramic image is provided to the user's right eye. <IMAGE>

Abstract: PURPOSE:To estimate the required precision by segmenting a short section of a signal in a time base, performing a spectrum analysis, detecting the candidates (approximate values) of pitch frequencies and only increasing the frequency resolution in the vicinity of the approximately values. CONSTITUTION:An input signal S(t) 20 is multiplied by an appropriate window function W(t) 21 to segment a short section. The data I(t) are frequency converted by a frequency converter 22, and spectrum analyzed by a spectrum analyzer 23 to perform an approximate value detection 24. At this stage, a filter process 26 is performed against the data in the frequency domain, an inverse conversion 27 is performed in a data computation section to put the signals back into a time domain and a down sampling 28 is performed. The data which are down sampled are made I(t) and are again fed back to the frequency converter 22 and the spectrum analysis 23 and a pitch frequency estimate 25 are performed to double the pitch frequency estimation precision. Should these processes are repeated for (n) times, the estimation precision is improved by a factor of 2<n>.

Abstract: PROBLEM TO BE SOLVED: To provide a front/rear wheel drive vehicle controller which can properly prevent the delay of the power generation of a generator driven by an engine from causing delay in assisted driving by an electric motor. SOLUTION: In addition to a generator 24, which is driven to rotate by an engine 10 for supplying electrical energy to an MG 28, a capacitor (power storage device) 48, is provided. When the MG 28 is driven in order to assist a pulling force at starting of a vehicle, electrical energy is supplied to the MG 28 from the generator 24 and the capacitor 48 simultaneously by a cooperative feeding means 84, so that the driving torque of the MG 28 becomes obmpf in its rise. With this constitution, the delay of the assistant driving of the MG 28 which is caused by the delay of the power generation of the generator 24 can be avoided properly, and the slippage of main drive wheels (front wheels 20) can be suppressed properly.

Abstract: A liquid charging nozzle plate (10) comprising a plate body provided with a plurality of through holes (11). This liquid charging nozzle plate (10) is used by fixing the same to a lower end opening of a liquid charging tube (67). The outflow of a liquid with which the liquid charging tube (67) is filled is prevented owing to the surface tension of the liquid in the through holes (11) of the liquid charging nozzle plate (10). On an inner circumferential surface (13) of each through hole (11), projections (15) are provided which extend in the circumferential direction so that the inner diameter of the through hole (11) decreases. Owing to the cross-sectional shape of this through hole (11), the dripping of the liquid from the through hole (11) can be prevented effectively. Even when the through holes (51) are formed cross-sectionally to an elongated slit-like shape, the dripping of a liquid therefrom can also be prevented effectively.   <IMAGE>

Abstract: At a smoothing spectrogram calculation portion (10), a triangular interpolation function having a frequency width twice that of the fundamental frequency of a signal is obtained based on information on the fundamental frequency of the signal. The interpolation function and a spectrum obtained at an adaptive frequency analysis portion (9) are convoluted in the direction of frequency. Then, using a triangular interpolation function having a time length twice that of a fundamental period, the spectrum interpolated in the frequency direction described above is further interpolated in the temporal direction, in order to produce a smoothed spectrogram having the space between grid points on the time-frequency plane filled with the surface of a bilinear function. Using the smoothed spectrogram, a speech sound is transformed. Therefore, the influence of periodicity in the frequency direction and the temporal direction can be reduced.   <IMAGE>

By encrypting the software employing a key (k1) which is different from that key (k2) which is employed in the decryption, better protection is obtained against unauthorized utilization when the decryption key is kept secret to the user. Further improved security is achieved by additionally executing scrambling-descrambling of the communication between the computer in which the software is utilized and the external unit in which the decryption key is stored. Also, the external unit is arranged such that it returns to the host computer, the result from its processing of data received from the host, the result then being utilized in the further execution of the respective program. <IMAGE>
