Title: Pitch detection circuit for sound signal
Inventor: TEJIMA ISAO
IPC: G10L25/90
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To shorten the processing time and save the power consumption by using an analong circuit capable of executing sum-of-product operation at a high speed for correlation operation and speeding up pitch detection. SOLUTION: An input sound signal is converted into a digital signal by an A/D converter 1 and the digital signal is inputted to shift register circuits 31, 32, delayed and outputted as plural tap outputs. Delayed digital signals outputted from the taps of the shift registers are inputted to a weighting synthetic circuit 4 to execute the weighted synthetic operation of the analog input sound signal. The initial value of the operation output is held in a sampling/ holding circuit 5 and its peak value is stored in a maximum value storage 6. The sampled/held value and a judgement threshold are mutually multiplied by a multiplier 7 and the multiplied result is compared with the peak value by a judging device 9, and when the peak value is larger than the threshold, a silence/voiced sound changing switch 10 is switched to the voiced sound side.  A sound pitch can be detected by measuring delay time from the initial time of the output of the weighted synthetic operation up to the peak value by a counter 8.

Title: Switching method for optical connector
Inventor: KAMIKO KAZUO
IPC: G02B26/08
Filed: 1987-12-25
Abstract: PURPOSE:To switch connectors at two distant positions speedily in a short time by performing the switching at both points synchronously. CONSTITUTION:A driving signal is sent from the CPU of a master device 20 to a slave device 21 through a transmission circuit 12 at the stage wherein the driving part 1 of the master device 20 becomes ready for switching. When the driving part 1 of the slave device 21 is also ready for switching at this time, a driving signal is sent from the CPU of the slave device 21 to the transmission circuit 12 of the master device 20. At the same time, the slave device 21 sends the driving signal to its driving part 1 through its timer 10. A specific delay time is set in the timer 10 of the slave device 21, so the driving signal sent from the slave device 21 to the driving part 1 of the master device 20 is delayed by said delay time. The driving part 1 of the master device 20 and the driving part 1 of the slave device 21 switch the optical connectors on receiving the driving signal from the slave device 21. Consequently, two switching devices 3 and 4 switch the optical connectors at almost the same time in synchronism.

Title: Video intermediate frequency signal detection circuit
Inventor: NISHIZAWA YUKIO
IPC: H04N5/455
Filed: 1988-12-27
Abstract: PURPOSE:To improve the voice or character multiplex performance by applying phase control of a PLL generating a reference signal of phase detection based only on a part not changed by the video content in a video intermediate frequency signal. CONSTITUTION:A current source 68 is connected to the emitter of a phase detection circuit 60 and a blanking line command pulse representing a blanking period is inputted thereto. When the video signal is within the blanking period, a blanking line pulse is theoretically at H, a collector current flows to a transistor(TR) 16 and the phase detection circuit 60 is active. Thus, the detection output or the phase error signal of a phase detection circuit 10 is not affected by a change in the content of the video signal. Since the signal is smoothed by an LPF 200 and inputted to a VCO 208, the oscillation frequency of the VCO 208 is unchanged by the content of image, and the oscillation phase is made coincident with the video carrier phase in an excellent way.
