Title: Driving method for stepping motor
Inventor: ENAMI KATSUYA
IPC: H02P8/32
Filed: 1985-02-15
Abstract: PURPOSE:To obtain an accurate stopping angle position of a rotor by connecting a resistor with one side winding group when exciting in two phases, thereby applying a displacement to the stopping position of the rotor. CONSTITUTION:A resistor 16 for limiting a current, for example, to approx. 3-20% is connected between the second phase and fourth phase windings B, D and a power source terminal 13. Thus, when exciting in the 2 phases, one voltage of two phase windings to be simultaneously excited becomes lower than the other voltage, and a difference occurs in the exciting currents. Thus, a deviated magnetic flux distribution occurs, and the stopping position of a rotor becomes displayed state. Even if the rotating direction of the rotor is different, the displacement of the stopping position becomes extremely small.

Title: Method and apparatus for performing range change with digital circuit
Inventor: SUREN IRUKURA
IPC: G06F1/02
Filed: 1986-02-13
Abstract: The invention relates to a range transformation method for transforming the normalized divisor in a division calculation to a range wherein the transformed value differs from one by no more than the quantity 2<-n>. The method and apparatus generate the transform multiplier value from a first high order "q" digits of the divisor and generate an out-of-range indicator signal from at least those same digits. The thus generated multiplier value is modified in response to the out-of-range indicator signal when an out-of-range condition is indicated. The apparatus employs a read-only-memory for enabling the generation of the transform multiplier value without requiring either large table look-up storage or multiplicative functions. As a result, various division methods requiring an initial transformation to provide a divisor which approaches one in value can be efficiently implemented.
