Abstract: PURPOSE: To adjust the sensitivity difference of each microphone in advance by subjecting the analog output of an output level adjusting means to A/D conversion, configurating an automatic gain control circuit and adjusting the level according to the deviation from a reference signal. CONSTITUTION: After the output signal of a microphone 1 via a gain fixing amplifier 2 is amplified up to prescribed gain by a level adjusting means 3, a D/A conversion is performed by a converter 4, this digital signal and a reference signal are compared by a microcomputer 5, the D/A conversion is performed for the deviation between the both of the signals by a converter 6, the deviation is made the control voltage of the level adjusting means 3, and an automatic control circuit 8. Therefore, before a microphone with the difference in sensitivity characteristic is used in its normal state mode, the sensitivity difference of each microphone can be adjusted in advance. On a manufacturing line, the dispersion of the sensitivity of the microphone can be exactly corrected and the initial value of an AGC circuit can be preliminarily matched with each microphone.

Abstract: PURPOSE:To provide a video/audio signal recording and reproducing device with high cost performance for sharing a teletext broadcasting signal processing circuit as the processing circuit of teletext information by turning a character code system in the case of recording the teletext information to teletext broadcasting interchangeable codes. CONSTITUTION:In the case of receiving, decoding and displaying teletext broadcasting signals, reception signals from a circuit 1 are supplied to an equalization circuit 4 and a separator circuit 6, character signals are separated and character data are decoded by a CPU 10, stored in memories 14 and 15, matrixed, outputted from a mixing/switching circuit 18 to a receiver and displayed. In the case of reproducing and displaying the teletext information recorded on a video tape, after reproducing signals from the tape are processed, the character data are tentatively stored in the memory 27. Since the character data and the teletext broadcasting interchangeable codes, the CPU 10 decodes them by using the same hardware and soft ware as in the case of the teletext broadcasting signals and output for display is outputted from the mixing switching circuit 18.

Abstract: PROBLEM TO BE SOLVED: To provide a multilayer interconnection board and manufacturing method thereof in which a press-fitting part is mounted and a fine wiring pattern is formed precisely. SOLUTION: A wiring pattern W is formed on front/rear outermost layers L1 and L8 of a multilayer interconnection board in which a plurality of both- sided wiring boards 1, 3, 5, and 7 where a copper foil Ma is formed on both surfaces of insulating substrates I1, I3, I5, and I7 are laminated, with a via hole formed across front-rear conductive layers of at least one both-sided wiring board among them. Here, the conductive layers L1 and L8 comprising the copper foil Ma which are formed on the surface of both front/rear insulating substrates of the outermost layers L1 and L8 are removed. The surfaces of the exposed insulating substrates I1 and I7 are applied with electroless plating to form a conductive layer N while electrolytic plating to form a conductive layer M on the surface.

Abstract: PURPOSE:To transmit digital data without adding additional information for protecting data of a parity code, CRC and ECC or the like which raise cost, and to take measures against noise without increasing a circuit scale at all. CONSTITUTION:In a digital data transmission method for transmitting a parameter corresponding to an instruction by following instruction data transmission from a transmission-side and transmitting instruction data and the parameter from a reception-side to the transmission-side as echo back, instruction data setting an address and the address as the parameter are transmitted from the transmission-side before write instruction data is transmitted, and address setting instruction data and the address are transmitted from the reception-side as echo back. The transmission-side compares whether the transmitted address coincides with the received address or not so as to recognize whether the address is accurately transmitted or not.

Abstract: PROBLEM TO BE SOLVED: To improve functionality by forming recorded data corresponding to a digital recording format for a first magnetic tape, successively forming each track obliquely along the longitudinal direction of a wide second magnetic tape, and continuously recording the two track portions of the recorded data of the digital recording format against each track. SOLUTION: A video audio signal of the data format in the digital video method is recorded while a rotary drum 11 having the same diameter as in the analog 8 mm method is rotated in the direction of the arrow a3 against an 8 mm video tape 10. The rotary drum 11 is provided with two magnetic heads 12A, 12B having a different azimuth angle at positions oppositely facing each other. The magnetic heads 12A, 12B successively form tracks 13 obliquely along the longitudinal direction of the 8 mm video tape 10. In this case, the two track portions of the data in the digital video method are continuously recorded against one track 13, with the data pattern in the digital video method unchanged.

Abstract: PROBLEM TO BE SOLVED: To take out digital data and superimposed signal by one set of A/D conversion circuits. SOLUTION: The transmission signal from a transmitter 1, in which an optional weak low frequency signal is superimposed to e.g. digital data subjected to I-NRZI modulation, is transmitted. The noise of wide band is generated 2 and added 3 to the transmission signal, and this signal added with the noise is received by a receiver 4. This received signal is supplied to the A/D conversion circuit 7 through an amplifier 5 and an equalizer circuit 6, then the digitization by the optional over-sampling is performed. This digitized signal is supplied to a digital signal detecting circuit 9 such as e.g. a Viterbi decoder through e.g. PR4 (partial response class 4) equalizer circuit 8, then the transmitted digital data are taken out. Also, the signal from the A/D conversion circuit 7 is supplied to a digital filter 11 for extracting the weak low frequency signal, and this extracted signal is supplied to a signal detecting circuit 12, then the weak low frequency signal is taken out.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head capable of suppressing an effect due to adjacent cross talk. SOLUTION: An azimuth angle is given to a magnetic gap (g), and deviation in the track width direction is given to a confronting position between magnetic gap forming projecting parts of respective magnetic core half bodies. In this case, the deviation is the one in the direction that the angle θ1 between a center line F between the confronting surface of the magnetic gap forming projecting part and a wall surface of a track width control groove 10 opposite to that and the azimuth direction of an adjacent recording track TB becomes larger than the angle θ between the magnetic gap g and the azimuth direction of the adjacent recording track TB.
