Hygienic tissue paper

A circuit for determining whether a digital circuit clock is operating normally. It includes a monitoring clock receiver for receiving a monitoring clock signal, a counter reset generator which generates a first reset signal in response to the monitoring clock signal, and a reset signal receiver for receiving a second reset signal and synchronizing the second reset signal with the monitoring clock signal. The second reset signal is also used to initialize a digital circuit pack upon power-on. The circuit further includes a monitoring counter circuit for sampling and counting a reference clock signal in response to the first and second reset signals to monitor the monitoring clock signal. The reference clock signal has a frequency twice that of the monitoring clock signal. A NAND logic unit is provided for outputting the monitored result in response to an output signal from the monitoring counter circuit so that the user can determine a clock error according to the monitored result. An output hold circuit is further provided for holding the monitored result from the NAND logic unit when the monitoring clock signal is abnormal.

A primary color video output circuit for limiting an input video signal. The circuit includes a clipping circuit, a reference voltage generating circuit and an amplifier. The clipping circuit limits the level of the input video signal based on a reference voltage generated by the reference voltage generating circuit. The amplifier is then used to amplify the clipped video signal.

PURPOSE:To obtain a demodulation circuit with excellent linearity in the FM demodulation range by inserting a group delay characteristic correcting device making group delay characteristics in a desired demodulation range flat to an output of a delay line connected to an output of a limiter, inputting said output to a multiplier and using an LPF so as to extract a DC component of the output as a result of the multiplication with the limiter output. CONSTITUTION:An output of the limiter 2 converting an FM modulation signal into a rectangular wave with a prescribed amplitude is fed to the delay line 3 and a group delay characteristic correcting device 7 making the group delay characteristics of the FM demodulation band flat in this order, the output of the limiter 2 is multiplied (4) with the output of the device 7, and the result of multiplication is given to a low.pass filter 5, from which a demodulated output is extracted. The group delay characteristics of a wide FM demodulation band are made flat by combining the group delay correcting device having a characteristic possible for compensating the group delay characteristics of the delay line therewith, the linearity of the FM demodulation characteristics is improved, a DG is improved to output a signal without waveform distortion.

PURPOSE:To control smoothly profile correction of a picture signal by providing a slice circuit where slice quantity is variable thereby controlling an amplitude of a profile correction signal so as to reduce noise. CONSTITUTION:A video signal inputted to an input terminal 1 is inputted to a profile generating circuit 2, from which the profile correction signal is obtained. The profile correction signal is fed to a slice circuit 6 having an input/output characteristic shown in figure and a small amplitude portion of the signal is eliminated at the circuit 6. In the slice circuit 6, the amplitude is controlled from no slicing state up to the maximum amplitude of the profile correction signal having the maximum slice quantity by using a control signal fed to a terminal 7. The signal from which the noise is eliminated by the slice circuit 6 is added to the original video signal at an adder circuit 4, and the signal whose profile is emphasized is obtained at an output terminal 5.

PURPOSE:To constitute the entire circuit with standard digital circuits by providing a counter reset by the 1st clock, a memory storing a part of bits of the said counter every time the 2nd clock is inputted and a detector detecting the coincidence between the memory value and the bit of the counter. CONSTITUTION:A bit number (n) of the counter 11 and a bit number (m) of the memory are selected as m=n=3 in convenience. The clock in figure (a) is inputted from an input point 16 to the counter 11 and the count-up is repeated by using a reference clock in figure (e) from an input point 14. The memory 12 stores the value of the counter 11 every time the 2nd clock is inputted in figure (f) from an input point 15. Figures h, i, j show a memory value corresponding to 3-bit of the counter 11 and the value at the trailing of the clock shown in the figure (f) is stored. The value and each bit of the counter 11 are compared by a coincidence circuit 13. The circuit 13 outputs a signal when all the corresponding bits are coincident. Thus, the said output signal has a period of the reference clock and is a signal whose phase is matched with the said 2nd clock. The large scale integration is facilitated.

PURPOSE:To execute the comb-line filter at a whole band with a low cost by dividing a wide band video signal into a high frequency signal (YH signal) and a low frequency signal (YL), frequency-converting the YH signal to a low frequency and using a narrow band general-use CCD.1H delaying circuit. CONSTITUTION:A wide band video signal reproduced from recording medium divides a video signal into two bands by a high pass filter 14 (HPF) and a low pass filter 15 (LPF). A YH signal separated by the HPF 14 is balance- modulated at a frequency fc of N1 times of fH by a balanced-modulator 16 (BM). The YH signal frequency-shifted to a low frequency is inputted to a general-use 1H delaying CCD circuit 18, 1H-delayed, inputted to an adder with the signal before 1H delaying, constitutes a YH comb-line filter and is converted to an original frequency by a BM 20. To an adder 31, the output signal of a YHcomb-line filter and the output signal of a YL comb-line filter timing- synchronized by a delaying line 25 are inputted.

PURPOSE:To maximize a contour correction effect without applying a malfunction to a synchronizing signal sampling by comparing the amplitudes of a luminance signal and a contour correction signal from a contour correction signal generating circuit, selecting the signal of the smaller amplitude and adding to the luminance signal. CONSTITUTION:The luminance signal is inputted from an input terminal 11. The luminance signal is transmitted to the contour correction signal generating circuit 12 and a contour signal component is sampled. A level comparison circuit 13 compares the direct current component of the luminance signal with the contour correction signal and removes whiskers generated below a pedestal level. The output of the circuit 13 from which the whisker signal is removed is added to an original luminance signal in an adder circuit 14. In such a way, the contour correction signal generated below the pedestal level is effectively removed and the effect in the contour correction of the luminance signal can be maximized.
