Title: Multi-input echo canceller
Inventor: KAWADA SHINICHI
IPC: G10L25/00
Filed: 1993-06-01
Abstract: PURPOSE:To maintain respective echo canceller parts in a state capable of removing echo signals well even when plural input sound signals simultaneously sound. CONSTITUTION:The input sound signals are converted to the sound signals for respective speaker parts by corresponding sound processing parts 31-3n. The sound signals for the same speaker part are synthesized by synthesis means 20r and 20l and sound-outputted from the speaker parts Sr and $1 and the sound reaches to a microphone part M as an echo. Transmission signals including echo components are successively passed through the plural echo canceller parts 11-1n to which the corresponding input sound signals are supplied as reference signals, the echo components are removed and transmission is performed. In this case, based out output from plural sound/silence detection parts 61-6n, a reception condition monitoring and controlling part 70 stops the adaptive operations of at least the echo canceller parts 11-1n to which the input sound signals of the sound are supplied as the reference signals when more than two input signals sound.

Filed: 1981-08-20
Abstract: PURPOSE:To improve the accuracy of tracing, through the decrease in a teaching correction time, by correcting the content of memory through the summing of a difference between an objective value and an output of a position detector to the content of memory. CONSTITUTION:Job information taught by the operator is stored in a memory 32.

Title: Terminal equipment and point of sales
Inventor: KAWAGUCHI MASAMITSU
IPC: G07G1/14
Filed: 1989-05-24
Abstract: PURPOSE:To prevent sales accumulation data from being erased and to improve the exactness of sales control by a controller by inhibiting the transmission of sales accumulation data to a radio unit when the radio parameter of the radio unit is different from the radio parameter of his own unit directly connected to the radio unit. CONSTITUTION:If a power supply in a POS terminal is turned on when the radio unit 3 directly connected to the POS terminal is replaced by a stand-by radio unit 3 due to its failure or the like, the radio parameter in the memory 28 of the radio unit 3 is automatically read out to the POS terminal side and compared with the radio parameter in a memory 12. When both the parameters are different from each other, the transmission of sales data to the radio unit 3 is inhibited and the sales accumulation data accumulated in the storage part 12 are not sent to the radio unit 3 by inspection or accurate calculation operation. Consequently, the sales accumulation data can be prevented from being erased and the exactness of sales control by the controller can be improved.

Abstract: PURPOSE:To suppress the temperature rise of a chip resistor by generated heat so as to improve the reliability of the resistor by preventing the deterioration of the resistance body of the resistor caused by the heat by providing a dummy electrode for heat radiation on the rear of the resistor. CONSTITUTION:A dummy electrode 6 for heat radiation is provided on the rear of this rectangular chip resistor and a conductor pattern 8 is formed on a wiring substrate 7 fitted with the resistor in a state where the pattern 8 is brought into contact with the electrode 6. Accordingly, when the resistor is soldered to the wiring substrate 7, the temperature rise of the chip resistor is suppressed lower, because the dummy electrode section 6 is brought into close contact with the substrate 7 and the heat generated from the chip resistor is radiated into the substrate 7. Therefore, a chip resistor which is improved in reliability and reduced in size can be obtained with a simple constitution. In addition, large power can be obtained with the chip resistor in spite of its small size.
