Title: Data access controller
Inventor: JII DAA TAI
IPC: G11C7/00
Filed: 1990-11-28
Abstract: PURPOSE: To execute a high speedy access processing for data by generating plural control signals from a reading signal and writing signal with a control circuit and outputting one of either external incoming data or data from a memory in accordance with the state of control signal with an output data latch circuit. CONSTITUTION: Plural control signals 22 are made of the reading signal 18 and writing signal 20 with the control circuit 12 and received with both the memory 16 and the output data latch circuit 14, and also incoming data DIN 24 fed from the external side are directly received with both the output latch circuit 14 and the memory 16 and further also accessed to data stored in the memory 16 with the output data latch circuit 14.

Title: Pulse width modulating amplification circuit
Inventor: TOKUGE AKIO
IPC: H03F3/217
Filed: 1988-12-28
Abstract: PURPOSE:To lower sprious interference to be inflicted on a radio, etc., by applying frequency modulation to a carrier signal for converting an input analog signal into pulse width by a random signal having no periodicity. CONSTITUTION:A control circuit 32 applies the FM modulation with demodulation width of about + or -20kHz to the fundamental wave of 200kHz from a fundamental wave oscillator 33 by a signal from a random signal oscillator 34. As a result, the levels of this fundamental wave and of a higher harmonic wave are shown in a figure. Accordingly, a peak is lowered to the original signal level for the fundamental wave and higher harmonic wave by spread spectrum of about + or -20kHz and lowering width is about 10dB. Thus, the sprious interference inflicted on the radio, etc., is reduced. Further, even when a modulated signal or higher harmonic wave is outputted to the acoustic output of the radio, etc., by any cause, the modulated signal is made hardly conspicuous since the periodicity is not obtained.
