Title: Video signal converter
Inventor: NAKAYAMA TADAYOSHI
IPC: H04N5/91
Filed: 1987-11-16
Abstract: PURPOSE:To facilitate the parallel processing of a memory by specifying a conversion frequency in a circuit applying A/D and D/A conversions to a high- definition video signal having a horizontal scanning frequency being twice the horizontal scanning frequency of a standard TV signal. CONSTITUTION:A matrix circuit 12 receiving high-definition analog R, G, B signals converts them into a luminance signal and a color difference signal. The output is written in a frame memory 18 via an LPF 14 and an A/D converter 16. When the stored picture in the memory 18 is displayed on a high- definition television monitoring device 38, switches 26, 28 are connected to the position of contact (a). Then the read of the memory 18 is implemented according to the reference clock of frequency 1560fH (fH is 31.5kHz) generated from a reference clock generating circuit 30. The video signal read from the memory 18 is converted into the three primary color signals R, G, B by the matrix circuit 32 and converted by the reference clock at a D/A converter 34. The output is fed to the monitoring device 38 via an LPF 36.

Filed: 1987-11-16
Abstract: PURPOSE:To reduce a line operation time by providing a talking party designation means, a storage means of voice source and a voice synthesizing means or the like and outputting a designated destination call voice to send a voice element data in a short time without using a high speed MODEM. CONSTITUTION:When a called party is designated by a talking party designation means 115 in a caller telephone set 110, a telephone number is read by a storage means 117 and a call is given according to the number by a network control means 119. After the detection of line connection, the data communication is started with a receiver side telephone set 150 and a voice transmission time data is sent from the device 110 to the device 150. Then the line is switched from a data communication means 113 to the voice synthesizing means 121 and the means 121 sends the voice signal for calling designated opposite. Thus, the device 150 switches the line from the data communication means 153 to a loudspeaker means 165 for a voice transmission time length and outputs designated opposite call voice signal. Thus, the voice element data is transferred in a short time without using a high speed MODEM to reduce the line operating time.

Title: Output circuit
Inventor: MAKABE TAKAYOSHI
IPC: H03F3/30
Filed: 1985-12-23
Abstract: PURPOSE:To improve the input/output transmission characteristic by adjusting a control voltage of a drain follower and a control voltage of a current source transistor (TR) based on a potential difference produced in a differential amplifier circuit receiving an input signal and a drain signal of the drain follower so as to expand the dynamic range. CONSTITUTION:When an input signal voltage rises and an output signal voltage does not follow the change in the input signal voltage, a potential difference is produced between differential input terminals of differential amplifier circuits 14 and 15. Since the gate voltage of a PMOS TR 9 and an NMOS TR 10 falls down and a sufficiently larger current flows from the PMPS TR 9 to a load resistor 3, the output signal voltage follows the change in the input signal voltage in a sufficiently wider range. When the input signal voltage falls down, the gate voltage of the PMOS TR 9 and the NMOS TR 10 rises and a sufficiently large current flows from the load resistor 3 to the NMOS TR 10, then the output signal voltage follows the change in the input signal voltage in a sufficiently wide negative range.
