Title: Floating-point numerical arithmetic unit
Inventor: IDE YUKIHIRO
IPC: G06F7/76
Filed: 1990-03-30
Abstract: PURPOSE:To obtain a floating-point numerical arithmetic unit capable of executing the operation of a single precision numerical data at twice the speed of a conventional arithmetic unit by adding the comparatively small number of hardware to a computing element capable of directly processing double precision numerical data. CONSTITUTION:In the 1st operation mode for computing double precision numerical data, a floating-point value is computed by the 1st code computing means 59, the 1st exponential part computing means 2 and a mantissa part computing means 1. In the 2nd arithmetic operation mode for computing single precision numerical data, a floating point is computed by either one of the 1st and 2nd code computing means 59, 60 and the means 1. In a 3rd arithmetic operation mode for simultaneously computing two different single precision numerical data, two floating point values are computed by the 1st and 2nd means 59, 60 and the means 1. This constitution makes it possible to execute single precision numerical arithmetic operation at twice the speed of the conventional arithmetic unit only by adding the comparatively small number of hardware.

Title: Electric-power control apparatus for induction motor
Inventor: HATANAKA TAKESHI
IPC: H02P27/06
Filed: 1993-03-08
Abstract: PURPOSE:To always operate an induction motor at an optimum power factor by a method wherein a pulse-width modulation signal is modulated by a modula tion parameter which has been compensated by the function of a supply voltage. CONSTITUTION:A function generator 48 responds to the supply voltage of a motor, and it generates many power-factor compensation functions which are changed on curve patterns which are different for every frequency. A function selector 50 responds to a frequency instruction signal 24a, and it selects an arbitrary function from the power-factor compensation functions. A multiplier 52 multiplies the output of a reference power-factor instruction device 46 by the output of the function generator 48, and it generates the pattern of an optimum power factor for the motor 12. The optimum power factor 52a is compared with a detection power factor 36a by a comparator 40, and a deviation is supplied to a multiplier 44 as a parameter 42a for modulation via an integrator 42. The multiplier 44 multiplies it by a reference voltage signal 28a, and it outputs a multiplied value as a modulation-reference-voltage signal 28'a. Since the pulse-width modulation signal of a pulse-width modulation circuit 32 is modulated by the signal, the induction motor 12 can be operated at a highest power factor.
