Title: Musical sound synthesizer
Inventor: MASUDA HIDEYUKI
IPC: G10H7/08
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To enhance the reality of musical sounds at a physical model sound source. SOLUTION: 101 to 10n are the string models constituted by the loop circuits having delay circuits 11 to 14 which simulate the propagation delays of string vibration and a terminating filter 15 which simulates the acoustic losses of the strings. An exciting waveform generating section 4 inputs the exciting signals, equivalent to the exciting vibrations caused by string hitting or flipping operations, into the loop circuits. Moreover, a sounding board system is simulated by the loop circuit consists of an adder 31, multipliers 32 and 33 and a sound board 30 having a transfer function F. The string models and the sounding board system are connected by a waveguide junction section. A prescribed weighting is added to the output of each loop circuit and is synthesized in an adder 35 and is again inputted to each loop circuit.  Thus, faithful simulation including the sound radiated from the board 30 is realized.

Title: Polarity switching type josephson driver circuit
Inventor: TAWARA SHUICHI
IPC: H03K17/92
Filed: 1986-09-30
Abstract: PURPOSE:To obtain a wide operational margin by disposing driver gate circuits on the both ends of a circuit to be driven in order to obtain driving currents of both polarities, and impressing the respective bias currents of gate circuits when respective input signals are impressed. CONSTITUTION:The bias currents that flow through the second and the fourth Josephson gate circuits 2, 4 to drive the circuits to be driven 16, flow only when input signals are supplied to the input lines 7, 9 of first and third Josephson gate circuits. Accordingly, even when one of second and fourth Josephson gate circuits 2, 4 is switched and the other receives a driving current, since the bias current hardly flows through the latter, the gate circuit does not switch. As a result, a polarity switching type drive circuit whose operational margin is about same wide as a single Josephson gate circuit can be obtained.
