Filed: 1984-01-13
Abstract: PURPOSE:To attain a large capacity and high speed by using a dummy cell structured in the same way as a memory cell and by generating a reference voltage used at the time of reading on the basis of a current flowing in this dummy cell. CONSTITUTION:A reference voltage generation circuit is configured by an element Q66 (dummy cell) which has the same structure and characteristics as the memory cell where a gate is connected to a power source and the source is connected to a grounded potential, a push-pull inversional amplifier IV4, IGFETQ65 and feedback resister Rfs. If a gate length is greater than designed values and the current flowing in the memory cell becomes less than the designed values, in case of selecting the memory cell under a ''1'' condition, the difference between output Vout of the push-pull inversional amplifier IV3 and a reference voltage VREF becomes [Von6-VREF6], which is almost not different from a voltage difference [Von5-VREF5] where the gate length is made according to the size of the designed values, thereby giving no trouble to a comparison detector at the next step when the detector detects. When the gate length becomes shorter than the designed values, results can be obtained in the same way as stated above.

Filed: 1978-01-19
Abstract: PURPOSE: To make integration easier by using excellent temperature characteristics at high vootage gain and also amplifier amplicable at power source.  
     CONSTITUTION: By using a differential amplifier consisting of the front stage differential amplifier 17 having the resistors 19 and 20 as the amplifier portion and the rear stage differntial amplifier 18 having current mirror 25 as constitutional element which is connected with the amplifier 17 by two-stage connection, the arrival of differential input voltage at a predetermined value is detected and then output signal is switched.

Abstract: PURPOSE:To obtain fixed braking effectiveness alway at fixed pedaling force, by a method wherein pressure from a pressure source is controlled by a control signal based on a data processing device to which a brake control signal is applied and auxiliary force to an output piston acting upon a master cylinder is controlled. CONSTITUTION:When an input shaft 25 of a brake booster 20 is moved leftward by pedaling of a brake pedal, and a piston 24, an output shaft 26 and a primary piston 51 of a master cylinder 21 are moved unitarily leftward, brake liquid pressure is generated by the master cylinder 21, through which a brake is energized and braking is carried out. In this instance, a reduced speed read out according to an output of a control input sensing sensor 47 detecting the size of pedaling force in braking is compared with actual reduced speed sensed by a reduced speed sensing sensor in a data processing device (not illustrated hereupon). Then an increase of the brake liquid pressure is contrived as the piston 24 is moved leftward by controlling a solenoid valve 38 and making pressure in a pressure chamber 34 increase according to a result of the above comparison.
