Title: Sampling frequency converter
Inventor: OZAKI MINORU
IPC: H04B14/04
Filed: 1982-08-09
Abstract: PURPOSE:To simplify a constitution, by performing the conversion of a sampling frequency by the combination of a digital circuit and an analog circuit. CONSTITUTION:An analog waveform (a) in the fig. A is obtained by passing a PCM signal at an input terminal 1 through a D/A converter 6 and an LPF7, a signal waveform (b) after delay is obtained at delay lines D.L. from an analog output signal of the converter 6. Thus, a waveform (c) in the fig. B is outputted from a difference signal arithmetic circuit 9. The waveform (c) is sampled with a sampling clock signal of a receiving side PCM device at an A/D converter 10, where the A/D conversion is attained. A PCM signal outputted from the converter 10 and a PCM signal delayed at a digital delay circuit D at the input terminal 1 are fully added digitally at an adder 11 and reduced to an output PCM signal to be fed to the receiving PCM device. Since the difference signal of adjacent sampling levels is A/D-converted, the required bit number of the converter 10 is less than that of the PCM signal, the accuracy required for the A/D converter is mitigated, and an inexpensive A/D converter is usable.

Filed: 1992-06-01
Abstract: PURPOSE:To eliminate the need for a level converter and to prevent a damage to a device through mis-connection by attaining the connection between interfaces with a different signal level. CONSTITUTION:An input level detection circuit 10 is made up of a comparator circuit to detect an input level of a signal inputted from an external device. The input buffer circuit 11 switches a signal level of the input circuit by switching its threshold level in response to the level detected by the level detection circuit 10. An output driver circuit 12 selects an output level in response to a level detected by the level detection circuit 10. For example, the signal level is selected by the output driver circuit 12 to switch the supplied power to the output circuit by an analog switch.

Title: Driving method for plasma display panel
Inventor: MAKINO MITSUYOSHI
IPC: G09G3/288
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To enhance the emission luminance, reduce the power consumption, and improve the display quality by setting an inter-electrode pulse shape generating one maintenance discharge into a shape combining a short-period high potential difference and a long-period low potential difference. SOLUTION: An inter-electrode pulse shape generating one maintenance discharge is formed by combining a short-period high potential difference and a long-period low potential difference. After a short-period high voltage, e.g. t1 =200 ns, V1 =200 V, is applied, a long-period low voltage, e.g. t2 =4 μs, V2 =130 V, is applied to form the pulse shape. The first point of the pulse shape is that the applying time t1 of the preceding high voltage is shorter than the period until the discharge current wave-form becomes a peak after a pulse is applied. The second point is that the long-period low voltage of the applying time t2 and voltage V2 can maintain an electric discharge with no high voltage applied. The pulse of this shape is utilized for a discharge maintaining pulse.

IPC: H04N5/945
Filed: 1988-06-10
Abstract: PURPOSE: To attain the error coverage in the case of calculation of a substitute value using an FIR filter even when an adjacent sampled value scheduled to be used for the calculation includes an error by replacing the sampled value including the error used for calculation of a substitute value with an auxiliary value. CONSTITUTION: When an error evaluation circuit 3 detects it that there is any error in one or a plurality of sampled values required for calculating a substitute value, while the sampled value required for the calculation is fed to a filter (FIR filter) 11 having a finite pulse response, a 2nd switch 10 is thrown to an upward position. Then a corresponding sampling value of a preceding scanning line is used for the FIR filter 11. A switch 14 is thrown to the upward position corresponding to a delay time of the FIR filter 11 and a substitute value calculated by the FIR filter 11 is given to an output side 12 and to an input side of a memory 13. Thus, the error is covered in the case of reproducing a digitally recorded video signal.

IPC: H04N9/896
Filed: 1988-06-10
Abstract: PURPOSE: To block the signal having an error from overwriting the signal hating no error by using error flags to be stored together with video data and write flags. CONSTITUTION: An error flag EF to be supplied together with the video data including an error is similarly stored together with the video data at the time of a writing and moreover, addresses in which the video data are written are added with signs by write flags WFs. In a read mode, the error flag EF is similarly read out to be supplied to another error correcting circuit and another error hiding circuit via an output side 23. Further, when the write flags WFs are erased during the read mode, the error flag EF is supplied from an output side 23. That is, the digital video data are scrambled before a recording. As a result. faults to be concentrated in one area can be hidden by distributing them to larger parts of a screen.
