Patent JP-S58139205-A (JP)
Title: Plant controlling method
Inventor: NOMURA MASAHIDE
IPC: G05B13/00
Filed: 1982-02-12
Abstract: PURPOSE:To control a control variable stably and safely, by operating an operation variable not subject to the manipulated value limit in addition to the ratio of the optimum manipulated value to said limit value, if the optimum manipulated value computed in using a model exceeds the manipulated value limit value. CONSTITUTION:An optimum control system 100 incorporating a model computes the optimum value of correction signals for fuel, spray, and each flow demand of recirculating gas with the other method based on the input of a load demand rate of change LDR from a master controller 200. The correction demand signal of each operation is computed by using a demand correction signal of each manipulated value to check whether or not each value is subject to an upper/ lower limit, and the optimum value is outputted to the master controller 200 when the value is within the upper/lower limit values. When the value exceeds the limit, the corrected optimum maniplated value is obtained by multiplying the absolute value of the ratio of the manipulated value limit value of the operation variable subject to the limit to the optimum manipulated value with the optimum manipulated value of the operation variable not subject to the limit.

Title: Cross coil moving-magnet type measuring instrument
Inventor: ARAKI FUJIO
IPC: G01D13/22
Filed: 1988-01-30
Abstract: PURPOSE:To prevent a needle deflection phenomenon for a low input frequency from an object to be measured by driving a needle with a low torque in case of a prescribed indication angle or smaller in a needle indication range. CONSTITUTION:A signal having a frequency proportional to the rotative speed of an engine or the like is converted to a voltage proportional to the frequency by an F-V converter 1, and this voltage is converted to a digital signal (a) by an A/D converter 2 and this signal is inputted to a ROM 3. Output numerical signals of X component and Y component to respective coils corresponding to the signal (a) are outputted from the ROM 3, and these signals are converted to analog quantities by a D/A converter 4 to supply power to cross coils X and Y. At the time of storage in the ROM 3, the output value reference of a range alpha smaller than the prescribed needle indication angle is set to a value smaller than the others. Thus, the needle driving torque is smaller in the range alpha, and needle deflection is difficult to occur though the input frequency is low.

Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce the number of required processes, by lapping the surface of a silicon wafer with a lapping material, cleaning the surface of the wafer with a H2 O2 water solution, and drying it to provide the dried surface of the wafer with a resistance to contamination. SOLUTION: A wafer is held between and lapped by the rotary iron discs to which a load of several thousand pounds is applied. The surface of the lapped wafer is contaminated by Al2 O3 water slurry and silica and hence is treated with a diluted H2 O2 solution. The wafer is dipped in the H2 O2 water solution and then is dried by air or rotation. After the wafer is dried, the wafer need not to be cleaned after lapping, and a preparation for a laser marking and a pre-etching cleaning is finished. Therefore, the surface of the wafer can tightly be coated with a SiO2 layer having a uniform thickness and a high density.
