Abstract: PURPOSE:To control the occurrence of a blind sector so as to attain accurate positioning by correcting the absolute value of the digital driving quantity of an operating piece by means of the addition of the minimum digit of the digital driving quantity required for the movement of a body to be controlled. CONSTITUTION:In a range when a position deviation DELTAx is -a<DELTAx<a with respect to + or -a forming + or -1 digit in the digital quantity of the position deviation DELTAx, a computer 1 sets the relation of input and output in a D-A conversion with respect to the position deviation DELTAx for preventing a conversion output voltage Vc from coming to be Vc=0 and the occurrence of the blind sector. Namely, a minimum voltage value required for slightly rotating a servo motor 5 as an actuator on which a table 9 as the body to be controlled is loaded is obtained, the minimum number of bits, which corresponds to the minimum voltage value, is added to a conversion output voltage digit in an area where the position deviation DELTAx is positive, and it is subtracted from the conversion output voltage digit in an area where the position deviation DELTAx is negative. Thus, the blind sector does not occur in actuator driving output and position control precision can be improved.

Title: Semiconductor capacitance element
Inventor: YASUE TADASHI
IPC: H01G4/06
Filed: 1989-06-14
Abstract: PURPOSE:To improve the integrity of a semiconductor device by a method wherein first electrodes are formed into column shapes. CONSTITUTION:First electrodes 2 made of polycrystalline silicon are formed on a semiconductor substrate 1 into column shapes. Further, a second electrode 4 made of polycrystalline silicon is formed on the first electrodes 2 with a dielectric film 3 between. The capacitance of such a semiconductor capacitance element is proportional to the facing area between the two electrodes. The facing area is the summation of the area of the parts where the first electrodes and the second electrode overlap each other vertically and the area of the parts where the first electrodes and the second electrode overlap each other horizontally. Further, the area of the parts where the first electrodes and the second electrode overlap each other horizontally is proportional to the number of columns of the first electrodes. As the number of columns is determined in accordance with a design rule which determines the widths of the first electrodes or the spacings between the columns, by employing a fine design rule, the capacitance of a unit area can be increased and the element area can be reduced. With this constitution, the integrity can be improved.
