Abstract: PURPOSE:To attain listening without no listening problem even with the reception by a conventional monaural receiver and also bringing the occupied band of a side band wave within a band being a similar degree to that of a conventional AB broadcast reception by transmitting a low frequency as the sum of left/right sound signals and a high frequency as a square mean value of the difference between the sum and the subtraction of the left/right sound signals. CONSTITUTION:The left/right sound signals L, R applied to input terminals 1, 1' are added/subtracted by a matrix circuit 2 and converted into a sum signal (L+R) and a difference signal (L-R). The sum signal (L+R) is modulated into a signal of (1+L+R)cosomegat at an amplitude modulator 3 and the difference signal (L-R) is modulated into a -(L-R)sinomegat at a balanced modulator 4. Outputs of the amplitude modulator 3 and the balanced modulator 4 are synthesized at an adder 5.

Title: Output buffer circuit with latch function
Inventor: MATSUBARA KIYOSHI
IPC: H03K5/02
Filed: 1979-01-26
Abstract: PURPOSE:To simplify the constitution of circuits by letting one circuit function as an inverter constituting a latch circuit and that constituting an inverted push-pull output circuit. CONSTITUTION:With control signal phic at a low level, MISFETQ1 is ON and MISFETQ2 is OFF, so that inverter circuits IN1 and IN2 will take reads prescribed by the input signal level. With control signal phic at a high level, FETQ1 if OFF and Q2 ON, so that circuits IN1 and IN2 will perform holding operation through a positive feedback loop. Since outputs of those circuits IN1 and IN2 are out of phase mutually, they can be used as input control signal for a push-pull output circuit and a latch function provides the constitution of an output buffer circuit. Further, substituting FETQ2 with a high resistance makes it possible to omit inverter circuit IN3 generating control signal phic.

Title: Electronic stringed instrument
Inventor: TAKABAYASHI YOJIRO
IPC: G10H1/00
Filed: 1988-01-14
Abstract: PURPOSE:To change the pitch of a musical sound only at the time of a bend execution by a performer by providing an inhibiting means for inhibiting the change of a pitch of a musical sound, when the movement of a string by picking the string is detected. CONSTITUTION:When a performer presses a string 3 against a sound pitch designating part 1, a position discriminating means 4 decides its constant position and sends out information related to the contact position to a musical sound generating means 6. On the other hand, when the string is picked, a string picking detecting means 5 detects string picking and sends out information related to string picking to the means 6. The means 6 generates the musical sound of a sound pitch corresponding to the contact position as long as the performer does not execute a bend operation. Thereafter, when the performer moves the string in the direction being different from the time of designating a sound pitch in order to give a bend effect, a bend sensor 7 detects it and instructs to vary the pitch of a musical sound to the means 6. On the other hand, the movement in the direction being different from the time of designating a sound pitch is generated in the string at the time of picking the string, as well, but this string movement is detected by an inhibiting means 9 and even if an instruction by a bend giving means 8 is given, the pitch variation of a musical sound is inhibited.
