A portion of the syngas is fed to C02 removal (122) to obtain the recycle C02 and cold box (130) to obtain a hydrogen stream (131) and a CO stream (135). The remaining syngas, hydrogen stream (131) and C02 from an associated process are fed to methanol synthesis (140), which produces methanol and a purge stream (124) supplied to the C02 removal unit. The methanol is supplied to an acetic acid unit (13)6 with the CO (135) to make acetic acid, which in turn is supplied to a VAM synthesis unit (148). Oxygen for both the ATR and VAM synthesis can be supplied by a common air separation unit (116), and utilities such as steam generation can further integrate the process. ® KIPO & WIPO 2007

Filed: 2005-01-10
Abstract: One or more programming operations are performed on a set of non-volatile storage elements. For example, the programming operations may include applying a set of programming pulses. A verify process is performed to determine which of the non-volatile storage elements have reached an intermediate verify threshold but have not reached a final verify threshold. One additional programming operation at a reduced level is performed for the non-volatile storage elements that have reached the intermediate verify threshold but have not reached the final verify threshold, and those non-volatile storage elements are then inhibited from further programming. Non-volatile storage elements that have not reached the intermediate verify threshold continue programming. Non-volatile storage elements that reach the final verify threshold are inhibited from programming.

Abstract: A method for calibrating error of sensor output voltage according to the error of power output voltage is provided to calibrate the sensor output voltage automatically by storing a calibration value to a memory linked with a CPU and referring to the stored calibration value. A CPU receives reference voltage through a communicator and stores the reference voltage to a non-volatile memory(S101), and the CPU receives power output voltage of a power supply unit from a voltage measurer(S102). The controller calculates a voltage difference between the power output voltage and the reference voltage, and calculates calibration data by using the voltage difference as a variable(S104). The CPU calculates an average of the calibration data by repeatedly calculating the calibration data(S105). The CPU stores the average calibration data to the non-volatile memory106. The CPU reads the average calibration data from the non-volatile memory. The CPU receives sensor output voltage from a sensor unit and generates sensor data by converting the sensor output voltage into a digital signal. The CPU calculates a value of sensor data by using a conversion formula using the average calibration data and the sensor data as the variable.
