Title: Musical waveform amplitude controller for electronic musical instrument having complement generator of floating point binary digit
Inventor: RARUFU DOITSUCHIE
IPC: G06F7/38
Filed: 1988-06-17
Abstract: PURPOSE:To obtain an envelope control circuit employing a binary digital logic circuit with the use of the complement of a binary floating point, by obtaining directly said complement with no intervention of an intermediate stage where the conversion is performed into a fixed point binary digit. CONSTITUTION:A mantissa counter 112 is provided with a mantissa counter of a modulo 8. An exponent counter 113 performs an adverse counting action with an underflow pulse received from the counter 112 and stores the component of a floating point number. Then the counter 112 starts an adverse counting action in response to a clock pulse received from a timing clock 114. When the music is produced, an ADSR control circuit 118 opens a gate 116 and the decimal point data received from a floating point complement circuit 50 is transferred to a high-speed multiplier 200. Thus the counter 113 performs an adverse counting action. When the counter 113 is set at 0, the circuit 118 starts a decay part of the ADSR curve calculation.

Title: Color noise suppression device
Inventor: YAMAMURA SOUHEI
IPC: H04N9/68
Filed: 1978-12-04
Abstract: PURPOSE: To secure suppression of the color noise at the dark area by providing both the resistance and the diode to the device and thus decreasing the amplification factor for the carrier chrominance signal of the band amplifier circuit in case the  luminance signal level changes from the prescribed value to the black level side.  
     CONSTITUTION: Resistances 16, 18 and 20 are selected along with setting of the voltage at joint C between resistances 16 and 18 in order to secure conduction for diode element 19 in case the luminance signal applied to the emitter of transistor 8 within video amplifier circuit 2 changes from the prescribed value to the black level side. The voltage at C features a fixed level when element 19 conducts and then lowers down according to the luminance signal to be cut off finally. The voltage at joint B between resistances 16 and 20 becomes higher than the voltage at C by the amount equivalent to the overlap voltage of constant voltage diode 17, and the overlap voltage difference of variable resistor 16 is kept at fixed value E and then lowered by the amount equivalent to the voltage to the earth point. At the same time, the control voltage is formed through the voltage division via the sliding terminal of resistor 16 to give control to the amplification factor. As the noise is conspicuous at the black areas on the screen, the above mentioned procedures are taken to obtain a good picture image.
