Filed: 1994-06-29
Abstract: PURPOSE:To reduce the influence of an address due to noise and to prevent false operation by generating a control signal for each read and write cycles by a row operation control circuit for controlling the high-speed access of a semiconductor storage. CONSTITUTION:One-shot pulse CAST is generated by the trailing edge of a column address latch signal CAL created by the delay of /CAS in a first page mode and an ATD signal which becomes a trigger for read operation is generated from the signal. In this case, CDE, PAE, and DOT signals are generated regardless of the presence or absence of the address change in a cycle 2 to activate a column decoder, a preamplifier, and an OEM circuit and an address which is the same as that of a previous cycle can be accurately read, thus preventing illegal data from being outputted even if noise is superposed on the address signal.

IPC: G11B5/82
Filed: 1981-09-22
Abstract: PURPOSE:To eliminate the adsorption to the surface of a medium at the queuing position of a magnetic head and to reduce the damage of the head and the medium, by limiting the queuing position of the head to a queuing zone where no lubricant is applied, when the revolution of the medium is stopped. CONSTITUTION:In a queuing mode, a carriage 2 moves down by its empty weight, and a magnetic head 1 is set at a queuing zone 4 at the outer circumference part of a medium 3. A lubricant is applied on the surface of the medium 3 to decrease the wear which is caused by the head 1, and the lubricant is left removed at the zone 4. Therefore no adsorption is produced between the head and the media regardless of the queuing for a long period. When the medium starts its revolution, the carriage 2 moves up from the queuing position by energizing a voice coil 5. As a result, a magnetic head 2 moves onto a CSS zone 6 of the inner circumference part of the medium 3. Thereafter the medium 3 turns.

Title: Pwm signal output circuit
Inventor: KANEAKI TETSUHIKO
IPC: H03K7/08
Filed: 1989-06-12
Abstract: PURPOSE:To suppress secondary distortion without increasing a noise level by applying the output of a pulse width modulator to one inverter for output as it is and applying the output to the other inverter while inverting a polarity. CONSTITUTION:A pulse width signal to be outputted by a pulse width modulator 1 is directly applied to an output inverter 3 and simultaneously applied to an output inverter 4 while inverting the polarity of the pulse width signal by an inverter 5. Then, the output inverters 3 and 4 invert the polarity of the input signal again. The output of a negative-phase-adder 6 is taken out as a pulse width modulation(PWM) signal output. Thus, since the outputs of the output inverters 3 and 4 are the negative phases, the vertical asymmetricity of since wave, which is outputted by each output inverter, is canceled and the generation of the secondary distortion can be suppressed. The change points of the respective output inverters are made coincident and the frequency to generate the spike-shaped noise is decreased to be half. Then, the noise can be suppressed to be increased.

Abstract: PURPOSE:To improve the quality of signal communication by providing a transmission/reception level adjusting means and always variably adjusting a transmission/reception level corresponding to a reception signal. CONSTITUTION:When a line is connected with an opposite station, a CPU 1 switches a line switching relay 10 and applies a signal from the opposite station through a matching transformer 12, 2-line/4-line convertion circuit 12, reception filter 14 and reception equalizer 15 to a MODEM 8. Next, automatic gain control data in the MODEM 8 are sampled and the reception level of the signal is measured and compared with a reference signal level set in advance. Then, the degradation state of the signal caused by the distance or the fault of the line is predicted. Based on a predictive result, a desired adjusting signal is outputted from an I/O port 9 and a frequency compensating value in a transmission equalizer 17 and the reception equalizer 15 or the attenuation rate of an attenuator in a transmission filter 16 is automatically adjusted. Thus, since the level of the transmission/reception signal can be always corrected optimumly, the quality of the signal communication can be improved.
