Abstract: PURPOSE:To improve the quality of speech of a loudspeaking telephone for conference, by estimating the damping coefficient of an echo line from an impulse response, and judging, whether or not an echo signal is to be suppressed by nonlinear signal processing from the damping coefficient. CONSTITUTION:The square of a sampled value row is smoothed and a damping coefficient alpha is found by means of a damping coefficient estimating circuit 13. The damping coefficient alpha is sent to a nonlinear process controlling circuit 14 and, if the damping coefficient alpha is smaller than a set threshold beta, a nonlinear processing circuit 12 is by-passed. When the damping coefficient alphais larger than the threshold beta, the nonlinear processing circuit 12 is actuated and a suppressing quantity is given. When an above-mentioned operations are made, the initialization is completed. After the speech is started, receiving speech signals x(t) arrive and, when an objective signal to be give to a microphone 3 is interrupted, transmitting speech signals z(t) are regarded as echo signals y(t). Then the output of a subtractor 10 is regarded as an estimated error signal and correction to the fluctuation of the echo line of an impulse response is performed by an estimation circuit 7.

Title: Semiconductor memory
Inventor: NAKASE YASUNOBU
IPC: G11C11/414
Filed: 1988-10-11
Abstract: PURPOSE:To shorten access time by flowing a current to one of first and second bit lines connected to a memory cell selected in accordance with write data given from an external. CONSTITUTION:At the time of write, a transistor TR QDD is made non- conductive because the base potential of the TR QDD in a word line discharging circuit WDIS is in the low level. As the result, the current of a constant current source IH does not flow to memory cells M11 and M12 connected to selected word lines WP1 and WN1, and a word line discharging current prescribed by a constant current IWDCS does not flow there. That is, the bit line discharging current prescribed by a constant current source BTDSCS is supplied to a pair of bit lines BP2 through TRs QBD21 and QBD2R having a signal TSD1 from a Y decoder YD as the base potential because the signal TSD1 and a signal YSD2 are in the low level and the high level respectively at the time of selecting the memory cell M11. Consequently, the potential difference between selection and non-selection of the memory cell is reduced. Thus, the access time is shortened.

Title: Ink jet printer
Inventor: SAITO ATSUSHI
IPC: B41J2/01
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To detect whether ink is emitted with high accuracy by arranging the optical axis of the light emitting element and photodetector of a photosensor at a predetermined angle with respect to the arranging direction of the nozzles of a recording head. SOLUTION: The detection optical axis between the light emitting element and photodetector of a photosensor is relatively set to an angle θ with respect to the arranging direction of the ink emitting orifices of a recording head. By this constitution, a tolerance range given in width W is generated and a problem from an aspect of accuracy is solved. That is, only one row is formed heretofore but, by the structure of this form, a tolerance range can be taken up to the range shown by the width W. Since a peak value being the output signal of the photosensor lowers when the angle θ is made large, the angle θcan not be increased. This angle is affected by the accuracy of the photosensor, the number of recording nozzles, the distance between nozzles or the diameter of the nozzles but, in this case, the angle θ is 3 deg..
