Title: Period coincidence judging circuit
Inventor: NAGANO YASUSHI
IPC: H02P7/28
Filed: 1992-04-28
Abstract: PURPOSE:To make the circuit configuration compact by judging the coincidence of the period based on a 1st clock signal and a command signal so as to eliminate the need for a magnitude comparator. CONSTITUTION:When a pulse to be measured (1st clock) PLS is generated, a reference period N is loaded on a count means 20. The count means 20 counts down the value N by -1 each by one clock CLK. Then the count means 20 outputs a binarizing signal (command signal) ZERO at an H level when the value N is equal to 0 on the occurrence of a succeeding pulse PLS and at an L level in other cases. A judging means 21 judges the coincidence of the pulse period based on the binarizing signal ZERO and the pulse PLS. Output signals SHORT and LONG of flip-flops FF1, FF2 both go to an L level when the period of the pulse PLS is coincident with the reference period N. For example, when the period is shorter than the reference period N, only the output signal SHORT goes to an H level.

Title: Interface device
Inventor: SAKAMOTO HIROSHI
IPC: H04L29/08
Filed: 1991-04-15
Abstract: PURPOSE:To enable data transmission from a peripheral device side to a data processor by successively transmitting comparing data from the data processor side to the peripheral device, comparing these data with desired transmitting data on the peripheral device side and returning a coincidence signal when the both data are coincident. CONSTITUTION:A CPU 1 on the side of the data processor such as a personal computer, etc., and a CPU 2 on the peripheral device side are connected by the signal line of centronics specification. By using ports D0-D7, the data for comparison of one byte are successively transmitted from the CPU 1 to the CPU 2 together with a STROBE signal. At the CPU 2, the transmitted data for comparison are successively compared with the data to be transmitted to the CPU 1 side. When the both data are coincident, a BUSY signal rises from a low level to a high level. Thus, the CPU 1 can recognize the data to be transmitted by the CPU 2. Therefore, the data are transmitted from the CPU 2 to the CPU 1.

IPC: H04M1/60
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To provide an echo cancellation method that employs especially two filters used for a telephone system. SOLUTION: This system uses two adaptive filters, that are, a main filter 10 and a background filter 50. The purpose of the background filter 5 is to ensure a model of the main filter 10 to be in a correct state. A main filter coefficient and a background filter coefficient are updated by various conditions and residual signals (L- RES1, LRES2) generated by each filter are compared. A set of filter coefficients used to generate an output signal (S- OUT) of an echo canceller is selected based on the comparison of the residual signals. The set of the filter coefficients is selected by copying a background filter coefficient to the main filter 10 or replacing a function of the background filter 50 with a function of the main filter 10.

Filed: 1981-07-13
Abstract: PURPOSE:To perform convergence adjustment quickly, by providing a correction data increase/decrease discrimination register for a cursor movement discrimination circuit and writing the correction data directly to a memory storing the amount of correction as nonvolatile information. CONSTITUTION:An adjusting point is selected at a cursor key of a control panel 1 and the address of the adjusting point is stored to a cursor counter 9. A write key changes a reversible counter 2 and writes the amount of convergence cor- rection to a frame memory 4 for the correction of the correction data. When the movement of the cursor is detected at a cursor movement discrimination circuit 21, the amount of correction from the frame memory 4 is transferred and stored in a memory 3 storing as nonvolatile information in the setting state of a correction data increase/decrease discrimination circuit 22. Thus, the convergence state is quickly pictured and the adjustment of the convergence can quickly be done.

Title: Coding/decoding processing control system
Inventor: KURIHARA HIDEAKI
IPC: H04N19/423
Filed: 1988-05-07
Abstract: PURPOSE:To prevent noise due to fluctuation of synchronization of a received coded data by transferring a coded data from a reception buffer to a 1st data area if the 1st data area is not in use and transferring the coded data from the reception buffer to a 2nd data area when the 1st data area is busy. CONSTITUTION:When an interruption flag is set before the start of coding processing, a coded data is transferred from the reception buffer 3 to the 1st data area 4. When an interrupt flag is set before decoding processing, if the 1st data area 4 is idle, the coded data is transferred and transferred to the 2nd data area 5 when not idle and the coded data is transferred from the 2nd data area 5 to the 1st data area 4 by the end of decoding processing. Thus, the memory capacity is saved and the fluctuation of frame synchronization of the received coded data due to the state change of a transmission line is absorbed by the 1st and 2nd data areas 4, 5, then the generating of noise is prevented.
