IPC: H03M1/14
Filed: 1990-03-12
Abstract: PURPOSE:To correct only the output of an A/D converter requiring correction by allowing the A/D converter to shift input and to add its output every time the converter goes to a low order, to the low order of k-bit, and outputting the result as a most significant digit of an A/D conversion data. CONSTITUTION:An analog signal (AS) fed to an input terminal 1 is AD- converted (ADC), a 16-bit digital signal (DS) is outputted to an output terminal 4. Each of conversion sections 23-20 has a 5-bit A/D converter 21, a 5-bit D/A converter 22, an amplifier 23, a memory 24, and an adder 25. The converter 21 AD-converts the signal AS to fed to an analog input terminal 20, the result is fed to the converter 22, which DA-converts the converted signal into an analog signal. The amplifier 23 subtracts the output of the converter 22 from the signal AS at the input terminal 20, amplifies the remainder at a multiple of 2<4> and the result is outputted at a subsequent input terminal 20. The adder 25 corrects the output of the converter 21 by a correction data stored in the memory 24 and outputs the result to a digital output terminal 27. The most significant bit location of the output of the conversion sections 23-20 is located at the MSB, 12th, 8th and 4th bit and adders 33-30 and the result is outputted at an output terminal 4.

Filed: 1986-03-18
Abstract: PURPOSE:To obtain a memory capable of executing high-speed electric discharging by discharging residual electric charge at the time of writing which is left on a connection line at the time of verify operation after writing information on a memory cell by a discharging means. CONSTITUTION:After the completion of writing on a cell, a signal D is activated to turn on a discharging transistor (TR) Q3.

After the completion of discharging, the signal D is inactivated to transfer the current operation mode to a verify mode. In said mode, a cell Q1 is kept at a selecting state by signals X1, Y1 and is in a reading mode, information written on the cell is transferred to a sense amplifier 6 through a TR Q2, amplified and extracted from an output terminal 7. The extracted information coincides with the information written on the cell without the influence of residual charge and precise verify operation can be attained.

Title: Coal saver for contact process sulfuric acid manufacturing apparatus
Inventor: AOKI KAZUO
IPC: C01B17/74
Filed: 1978-05-22
Abstract: PURPOSE: To enhance the recovery rate of waste heat as well as prevent the corrosion of heat- transmitting tube by heating in advance the water to be supplied to heat-transmitting tube inside  coal saver by a preheater to a temperature more than the dew point temperature of sulfuric acid.   
     CONSTITUTION: The SO 2 -containing gas 1 flows downwards from the upper inlet of the coal  saver body 2 and then goes out of the outlet of the lower side, and on the other hand, the boiler  supply water 4 sent through the boiler supply water pump 3 is heated by the preheater 5 for boiler  supply water, for example, and then supplied to the lower inlet (d) for boiler supply water of the  heat-transmitting tube 6, where the water is gradually heated by the gas 1 while ascending and  then goes out of the upper outlet (e) for boiler supply water to enter into the steam drum 7.  Thus, the surface temperature of the heat-transmitting tube 6 near the gas outlet becomes higher  than the dew point temperature of sulfuric acid all the time and the corrosion of the tube can  therefore be prevented because the boiler supply water 4 is heated in advance to a temperature  more than the dew point temperature of sulfuric acid, and also the recovery rate of waste heat  can be raised because the gas temperature at the outlet of coal saver can be lowered to 170 to  190°C.
