Title: Detecting circuit for special pattern signal
Inventor: SAGA RYOKICHI
IPC: H04L7/08
Filed: 1985-07-03
Abstract: PURPOSE:To decrease the number of circuit elements of high speed motion and the power consumption and to make the operation of the titled circuit speedy by providing N-pieces of pattern detecting circuits in parallel operation each of which operates with 1/N of the frequency of the clock signal of a reception signal. CONSTITUTION:The high-speed input signal data is converted to N-pieces of parallel low speed signals by a series-parallel convertor circuit 1 based on the output clock from a frequency divider 2. The N-pieces parallel low speed signals are inputted to an N-line shift register 3 that shifts with the 1/N clock. Among the outputs of the register 3, N groups of the M bits each of which is shifted one bit from each other are taken out at the high speed side and respectively inputted to the N-pieces of pattern detecting circuits 4-1-4-n, and the relative value in relation to a reference pattern is respectively calculated. Because the pattern detection is executed at every N-piece bit of the input signal, the detecting circuits 4-1-4-n operate at a 1/N speed, and the detection pulse outputted after the pattern detection has an N-bit width.

Title: Driving device for variable power optical system
Inventor: HOJO HAJIME
IPC: H04N1/107
Filed: 1985-07-03
Abstract: PURPOSE:To transfer an optical path length adjusting mirror and an image forming lens to the specified position of variable power within a short time by providing a drive control means which activates a stepping motor of the optical path length adjusting mirror in slow-up motion. CONSTITUTION:In case the stepping motors 19 and 26 are drive-controlled by a CPU 29 through respective drivers 30 and 31, three kinds of slow-up speed profiles are used. The first type is used for forcively stopping a mirror unit or the image-forming lens at the target position of variable power. The second type is used for moving the said components in slow-up motion then at specified rotational speed and then stopping at the target position by slow-down motion. And the third type is used for moving by slow-up motion, increasing the rotational speed and slowing down to stop at the target position i.e. a triangular driving. By executing the aforementioned control, the rotational speed of the motors 19 and 26 can be rapidly increased, and therefore, the mirror and the lens are transferred to the target position of variable power in a short time.

Filed: 1994-06-28
Abstract: PURPOSE:To detect a voice segment with high precision without being adversely affected by the change rate of a crest value by computing voice signal starting and stopping positions, which are buried in the noises, from inputted voice signals. CONSTITUTION:A first comparator 5 detects a position K1 at which the crest value of the input signals from a voice amplifying circuit 2 exceeds the signal level that is obtained by averaging the noise pattern from a noise recognition means 10 in an averaging circuit 12 and the input voice detection signals are transmitted to a waveform predicting circuit 13 and a noise pattern editing circuit 10a. The circuit 10a discriminates the voice signals, which are inputted prior to the input voice detection signals, as noises and a noise pattern memory 10b keeps the discriminated noise level. A region detecting circuit 10c, which discriminates the inputted voice signals become less than the noise level, detects that the input signals are reduced. The detection signal is checked whether the signal lasts longer than a prescribed time or not and if it lasts longer than the prescribed time, the circuit 10c outputs a voice input completion signal.

IPC: B01D53/38
Filed: 1988-06-16
Abstract: PURPOSE:To deodorize a gas contg. basic malodorous components as primary malodorous component and having high intensity of the malodorous components or large fluctuation of the intensity thereof by neutralizing and removing basic malodorous components in a first packed bed with acidic washing water generated in a second packed bed where malodorous components are decomposed by microorganisms. CONSTITUTION:Washing water sprayed through a spray water nozzle pipe 15 washes off decomposed products of malodorous components generated by the effect of microorganisms sticking to the surface of a second packed bed 13. Basic malodorous components in the gas 10 to be treated are neutralized and removed by allowing the gas to contact with the acidic washing water in a first packed bed 12. The gas to be treated freed of a major portion of the basic malodorous components is introduced into a second packed bed 13, where the gas is allowed to contact with microorganisms. Thus, residual malodorous components in the gas are decomposed, and discharged as odorless gas 10a into atmospheric air from the top of a deodorizing tower 1. Thus, the load of the second packed bed 13 is reduced and possibility for causing clogging is also reduced even if the intensity or fluctuation of intensity of the malodorous components is large.
