Title: Fm demodulator through carrier direct injection and synchronization
Inventor: OOSAKI MASASHI
IPC: H03D3/06
Filed: 1979-01-26
Abstract: PURPOSE: To reduce distortion and noise while simplifying circuit constitution by branching a FM signal by a hybrid and then injecting one signal into an injecting- synchronizing oscillator and applying the other to a phase detector for a phase comparison with an oscillator output after locking.  
     CONSTITUTION: A FM signal inputted to hybrid 1 is made adequately out of phase (normally 90°) with injecting-synchronizing oscillator 2 by a line and then level- adjusted before being sent to phase detector 3. At this time, a phase shift synchronizing with the FM signal and in proportion by modulating is caused at the output of oscillator 2, and consequently the demodulated signal of a FM wave appears at the output of phase detector 3. Thus, receiving conversion for FM-wave demodulation, receiving local oscillation, IFAMP, AGC, AMP, LIM, synchronizing oscillator, etc., are unneeded.

Title: Accepting device for storage access
Inventor: TSUKIZOE KOUICHI
IPC: G11C11/406
Filed: 1981-01-26
Abstract: PURPOSE:To minimize the influence of refreshment upon another device, such as a processor, by varying the acceptance priority level of a refreshment access request with time and by inhibiting a refreshment access request for a constant time. CONSTITUTION:The delay circuit 15 of a priority circuit 1 delays a processor access acceptance inhibition signal 161 by time TW behind a refreshment access signal 103, so the access request signal 101 of a processor P has priority to the signal 103. Similarly, the signal 101, an access request signal 102 from a processor Q, and the signal 103 are accepted preferentially in this order in the time TW and the signals 103, 101 and 102 are accepted in order after the time TW. During two machine cycles of the time TW after the FF24 of an acceptance detecting circuit 2 is set by timing signals 104, 105 and 201 in every machine cycle, a refreshment acceptance inhibition signal 171 goes down to a 0 to inhibit the acceptance of refreshment. Consequently, the influence of refreshment upon a device such as the processor is minimized.
