Filed: 1987-09-28
Abstract: PURPOSE: To stop emitting sounds without producing an unnatural noise even in varying the musical interval by storing an attenuation flag, which stops emitting sounds, in preliminarily stored waveform data and successively reading out it. CONSTITUTION: An attenuation flag discrimination part 9 detects the attenuation flag from waveform data successively outputted from a waveform control part 8; and if its value is one, an attenuation indication signal to attenuate the envelope is outputted to an envelope control part 10.

Hereafter, the envelope control part 10 successively reads out envelope data for attenuation from the envelope memory part 4 while the attenuation indication signal is outputted, thereby attenuating envelope data outputted to the multiplier 6 with time. Thus, emitting sounds is stopped.

Title: On-delay circuit
Inventor: YOMOGIHARA KOICHI
IPC: H03K17/292
Filed: 1985-10-31
Abstract: PURPOSE:To improve the fail-safe performance of an on-delay circuit which is equipped with an oscillator operating with an input voltage as a power source and an AND circuit by applying the gate voltage of PUT or the base voltage of UJT to one input terminal of the AND circuit. CONSTITUTION:If a resistance R4 impressed with the gate voltage of PUT or the base voltage of UJT is broken before the output pulse P1 of an oscillator 3 is generated after the input voltage Vin is impressed, an input to an input terminal of the AND circuit 5 is ceased. Therefore, even if the oscillator generates the output pulse owing to the wiring breaking of the resistance R4, the delay output V0 of the resistance R4 is held at zero V and the fault mode of the side where an on-delay time Td1 is extended is entered, so that the fail- safe performance is obtained. Namely, a capacitor C3 is connected to the gate G of PUT through a diode D3, so no input is impressed to the input terminal A of the OR circuit 5. Therefore, the AND condition is not satisfied, so the output V0 of the AND circuit 5 is not generated, so fail-safe operation is carried out.
