Title: Digital filter
Inventor: KIKUCHI ATSUSHI
IPC: G10L19/00
Filed: 1990-06-07
Abstract: PURPOSE:To realize a calculation for apporximating the amplitude characteristic with high accuracy at high speed by converting a cut-off frequency and a maximum frequency in a digital region into a correction frequency subject to correction of distortion by bilinear s-z conversion, a correction transfer function whose amplitude characteristic is coincident with an analog region transfer function, and applying the bilinear s-z conversion to the function so as to obtain a digital region transfer function. CONSTITUTION:A cut-off frequency and a maximum frequency in a digital region are converted into a correction frequency subject to correction of distortion by bilinear s-z conversion respectively, and a correction transfer function whose amplitude characteristic is coincident with an analog region transfer function at the correction frequency is obtained. The correction transfer function is converted into a digital region transfer function by the bilinear s-z conversion. A digital filter having the said transfer function is easily realized by adjusting coefficients of multipliers 2 - 5,8,9. Thus, the amplitude characteristic of the transfer function in the analog region is approximated with high accuracy from a low frequency region to a high frequency region and the transfer function in the digital region is calculated at high speed.

Title: Phase locked loop circuit
Inventor: INATOMI SHOICHI
IPC: H03L7/085
Filed: 1984-07-19
Abstract: PURPOSE:To reduce restriction of output pulse width of an edge detecting circuit by using a phase comparator that compares phase of output of an input signal edge detecting circuit and output of a clock edge detecting circuit. CONSTITUTION:The edge detecting circuit 1 detects edge of rise and fall of input signals and gives detected pulse D to a phase comparator 5. The comparator 5 generates pulse K of pulse width that changes between 0-1 clock and pulse L of 1/2 clock width according to phase difference between clock C from VCO3 and detected pulse D. An LPF2 integrates pulses K, L and controls the VCO3 by the output. Thus, pulse of the clock C is changed and phase locked loop with the input signal I is realized. Thus, it becomes not necessary to make output pulse width of the edge detector 1/2 clock accurately, and restriction can be lowered.

IPC: G03B21/00
Filed: 1977-12-14
Abstract: PURPOSE: To rapidly carry out how to manage the trouble by automatically displaying how to manage the occurrence of process trouble in the order of priority.  
     CONSTITUTION: Process input/output device 2, central processing unit 1, slide projector 4, operator console 5, and memory 6 are combined together. Thus, if trouble signal S1 from the actual spot is inputted, the central processing unit 1 deduces the picture number by making the picture number in the memory 6, priority order data D, and trouble signal S1 correspond one another. Then the presence or absence of automatic display prohibition number S4 of the slide projector is judged. When the prohibition signal S4 shows prohibition, watch-and-wait lamp L is lighted, and one waits till the signal S4 is released. When the signal S4 is released, one outputs the picture selection signal S2 for trouble to the slide projector 4 so as to show the trouble. In addition, when plural signals of trouble occur, the high priority signal is shown.

Digital data of these signals constitute their own DCT block of a horizontal pixel x vertical eight pixels in a DCT black constitution part 2, and the block is outputted to a DCT part 3. The DCT part 3 outputs a DCT coefficient that it an operation result, which is quantized to constitute a macro block at a quantization part 4. A variable length encoding part 5 sequentially inputs a code word which is acquired by encoding the DCT coefficient with variable length from a low frequency component to buffer memories 6 and 7 and a bit number counter 8. A SYNC and ID addition part 10 adds a SYNC and an ID to the code word, and an error correction encoding pat 11 adds an error correction code to it.  Recorded data which is encoded in a record channel encoding part 12 is sent from an output terminal 13.

Title: Automatic gain controlling system
Inventor: ARAI RIYOUJI
IPC: H04N1/407
Filed: 1981-09-22
Abstract: PURPOSE:To obtain a stable AGC operation even for picture information having continuous black pictures, by performing a periodical forced discharge of a capacitor in a charge/discharge circuit controlling the gain of a picture signal amplifier, with use of a forced discharge circuit. CONSTITUTION:A pulse signal which is generated at a pulse signal generating circuit 11 at the outside of effective screen and synchronized when a scanning point is at the outisde of the effective screen, is applied to a force discharge circuit 12, and a charge stored in a capacitor of a charge/discharge circuit 7 is periodically discharged while this pulse signal is applied. Since a charge amount per one period is more than the amount of discharge at first, the capacitor potential is gradually increased but when the potential rises to a certain value, the amount of charge/discharge is balanced and the charge/discharge is repeated around a prescribed value. Thus, since the gain of an amplifier 10 keeps increasing until it attains the maximum value, a defect that the balck level exceeds a white/black discriminating level can be eliminated.
