Title: Electronic musical instrument
Inventor: OKAMOTO SEIJI
IPC: G10H7/02
Filed: 1993-06-07
Abstract: PURPOSE:To provide the electronic musical instrument which can employ a system that compresses and efficiently stores waveform data on a musical sound waveform without altering the conventional constitution of a musical sound generating mechanism. CONSTITUTION:This electronic musical instrument is equipped with a waveform ROM 21 which stores the waveforms of various sounds as the form of compressed waveform data, a sound source system 13 having a waveform reproduction part 31 which expands the compressed waveform into normal PCM waveform data, and a waveform RAM 23 which temporarily stores the waveform expanded by the waveform reproduction part 31. When a key is pressed in this electronic musical instrument, the compressed waveform data are expanded as the PCM waveform data in the waveform RAM 23. Consequently, even when an optimum digitization system is used corresponding to a timbre, the musical sound generating mechanism generates a musical sound on the basis of the PCM waveform data at all times. Therefore, the storage efficiency of the waveform data is improved without altering the constitution of the musical sound generating mechanism, and many kind of timbres and a reproduced sound of higher definition can be generated.

IPC: H04J3/06
Filed: 1980-10-01
Abstract: PURPOSE:To restore rapidly synchronization for input data. CONSTITUTION:A frame pattern detected by a frame pattern detecting circuit 1 is inputted to collating circuits 2-1-2-n in parallel. A clock control circuit 3 inputs a clock signal to a reference pulse generating circuit 4, and the reference pulse generating circuit 4 generates reference pulse (1)-(n) on a basis of this clock signal. Reference pulse (1)-(n) are inptted to collating circuits 2-1-2-n respectively and are collated with frame pulses inputted from the frame pattern generating circuit 1. Each of collating circuits 2-1-2-n generates a coincidence signal and inputs this signal to a corresponding protection circuit if the inputted frame pulse and the reference pulse coincide with each other. If this coincidence signal is inputted three times continuously, each of protection circuits 5-1-5-n outputs a signal indicating coincidence of synchronization; and otherwise, it outputs a signal indicating step out.

Title: Controller for color demodulator
Inventor: NAKASE YOSHIMORI
IPC: H04N9/465
Filed: 1980-10-02
Abstract: PURPOSE:To avoid the permanent stop of a multi-vibrator even in case of phase shift of a reference subcarrier, by providing a burst pickup circuit separately, and detecting the output with the reference subcarrier and giving it to a voltage controlled oscilltor. CONSTITUTION:When a signal is produced from a line identifying signal generating circuit 4, the output of a control circuit 3 is at low level and the output of an AND circuit 10 is also at low level, and a burst pickup circuit 5 makes no burst pickup operation. Thus, the DC component of the output of an unidirectional circuit 6 is lost and the circuit 4 stops the production of the reset signal. A burst pickup circuit 8 operates the circuit 5 independently, the burst output of the circuit 8 is detected with the reference subcarrier at an APC phase detector 9 and the output is given to a voltage controlled oscillator 11 for PLL circuit operation. Thus, even if the phase of the reference subcarrier has an error, no multivibrator stops permanently.
