IPC: H04B3/20
Filed: 1988-05-13
Abstract: PURPOSE:To enhance a speaking quality by making variable the voice recognizing threshold of the input voice detecting part of an echo cancellor according to the rise elapsed time of an AGC circuit at the time of the speaking start, and decreasing the extreme unbalance of AGC circuit gain generated after the start of service. CONSTITUTION:When a speaking person on a B side starts speaking, an output voice detecting part 2 on the B side recognizes an echo cancellor EC as a voice in the same way as on an A side, and simultaneously, the ON-signal of a comparator in the detecting part 2 counts a timer 6. Then, the deciding threshold corresponding to a counted value is generated, and it is applied to an input voice detecting part 1 on the A side. When the moving mean power of the input signal exceeds the deciding threshold, the detecting part 1 makes the signal into the voice and sends the moving mean power to a turn-around canceled quantity detecting part 4. The detecting part 4 decides whether or not the output cancelor EC signal of the detecting part 2 is <= a decision level, and the input signal to the cancelor EC of the deciding part 1 is >= the decision level, and when both conditions are satisfied, a gain control part 5 controls the gain of an AGC circuit on the A side.

Title: Coordinate input device
Inventor: KANEKAWA MAKOTO
IPC: G06F3/0488
Filed: 1994-05-30
Abstract: PURPOSE:To detect a state other than a one-point contact state and to correct a coordinate position in case of multiple-point contact by detecting variation in electric characteristics of a resistance film which is caused by the multiple- point contact. CONSTITUTION:When the X-directional coordinate of a depression point is inputted, switching circuits are brought under switching control so that the switching circuit A is set to the side of a power source X1 and the switching circuit B is set to the side of a power source X2. Then, an A/D conversion part 14 detects the potentials of electrodes Y1 and Y2 and a multiple-point contact detection part 18 detects the potential difference between the electrodes Y1 and Y1 and judges that there is a multiple-point contact when the potential difference is larger than a specific value. Once the multiple-point contact is judged, the multiple-point contact detection part 18 informs the user by an indication part 20 that the multiple-point contact operation is executed and coordinate input is inhibited without coordinate detection by a digital processing part 16. When it is judged that the multiple-point contact operation is not executed, the X coordinate is detected and inputted as usual. Those precessing are performed similarly when the Y coordinate is inputted.

IPC: H03M13/00
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To attain the reduction of the circuit scale by performing decoding operation with a decoding operation input parameter, performing correcting operation with a generated decoding operation output parameter and selectively storing the decoding operation input and output parameters. SOLUTION: While input data concerning a C1 code are inputted/outputted in a scratch pad memory 305 of the memory block 302, its syndrome (S) and erasure position (X) are calculated. At such a time, a decoding operation processing part 304 executes G2 decoding, and a register 314 is operated as a working register. After C2 decoding is completed, an error value (E) and an error position (X') are inputted to the register 314 as decoding operation output parameters for the correcting operation of the C2 code. Then, when the decoding operation input parameter of C1 is completely inputted and C2 decoding is finished, switches 310 and 315 are changed over, and respective data are exchanged. Thus, a register 313 is shared for decoding operation input and output parameters.

IPC: G02F1/29
Filed: 1983-06-30
Abstract: PURPOSE:To decrease aberration by disposing plural optical deflecting means in such a way that plural deflected light pass substantially through one point. CONSTITUTION:An IDT (comb-shaped electrode) 21 has a min. central frequency and is so inclined to conducted incident light 20 that an SAW surface acoustic wave 25 satisfies Bragg conditions. The SAW 25 intersects with the light 20 at the point C and diffracted light 29 is emitted but the diffraction angle is small. The IDT 21 is so disposed that the central light of the light 29 passes through the central point B of a lens 33. Like the IDT 21, IDTs 22-24 have successively increasing central frequencies at which SAWs 26-28 are inclined with respect to the light 20 so as to satisfy the Bragg condition and intersect with the light 20 at D, F and F thus generating diffracted light 30-32. The central rays of the diffracted light 29-32 are all passed substantially through the central point B of the lens 33 in the above-mentioned way, by which the diffracted light after passage through the lens 33 is kept practically free from the influence of the error in the manufacture of the lens over the entire operating frequency band of the IDTs.
