Title: Subband type echo canceler
Inventor: AMANO FUMIO
IPC: H04B15/00
Filed: 1990-02-21
Abstract: PURPOSE:To improve an echo suppressing characteristic by outputting respective band signals from a dividing/tinning processing part as complex signals and using a complex signal area for executing echo erasing operation by an echo canceler group in each band. CONSTITUTION:The dividing/thinning processing part 1 divides a received signal into the band signals of N channels through a filter bank 11 and then thins the sample point of each band signal to 2/N by a thinning part 12. An output signal from the thinning part 12 is outputted as a complex signal in addition to a real part component based upon convensional technique. A dividing/thinning processing part 2 also is similarly constituted of a filter bank 21 and a thinning part 22 and an output signal from the thinning part 22 is outputted as a complex signal. An echo canceler group 4 forms pseudo echos of respective channels through adaptive digital filters 411' to 41n' based upon respective band signals obtained by dividing the received signal by the processing part 1 and subtracts the pseudo echos from respective band signals obtained by dividing a transmitted signal by the processing part 2 to obtain a residual signal in each channel.

Filed: 1980-03-31
Abstract: PURPOSE:To detect the input signal level of front end of superregenerative system, by detecting the frequency shift in quenching frequency of the quenching oscillating circuit, in the superregenerative receiver. CONSTITUTION:The reception input received at the antenna is amplified at the buffer amplifier 2a of superregenerative system front end, and it is mixed with the quenching output voltage, it is converted into a low-frequency output with the low pass filter 2c. After it is amplified at the next low-frequency amplifier, the alarm device is driven via the rectifying, wave shaping and identifying circuits. The output of the quenching oscillation circuit 2b is fed to the band pass filters 121-12n having the frequency characteristics of f1<f2<...<fn and the frequency shift detecting means consisting of the signal level discriminating output 3. Since the frequency shift of the quenching output is proportional to the level of the electromagnetic wave signal, an output is generated only to the filter 121 when the electromagnetic wave signal level is e1, and an output is generated at the discriminating output D1, allowing to measure the signal level.

IPC: C01B13/11
Filed: 1978-04-11
Abstract: PURPOSE: Electrode attached with dielectric which generates a large amount of heat contains a low temperature boiling cooling agent in its inside. The electrode is cooled by cooling medium heat transmission by phase change boiling, thereby treating substantially all of heat generated in O 3  production.  
     CONSTITUTION: In silent discharge, O 3  generation heat causes a low temperature boiling cooling medium 14 such as fron to boil which is sealed in the internal metal electrode 7. The vaporized medium vapor is collected in the upper space and cooled by the fins 15 and water 12, and condensed. The condensate is returned to the lower pool and this process is cycled to efficiently expel the heat generated in silent discharge. The discharge heat generates substantially within the dielectric 13, and as such, maintaining the dielectric below a specific temperature keeps the discharge gap 8 at about same temperature, or the boiling point of the cooling medium 14. The process eliminates the need of cooling pipe installation inside the electrode, resulting in easy assembling and a compact O 3  generator.
