Title: R/d converter
Inventor: TAKEHARA TAKAO
IPC: H03M1/22
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To provide the R/D converter which can respond fast. SOLUTION: An AD converter 10 converts the sine wave output and cosine wave output of a resolver from analog to digital when the exciting sine wave of the resolver has a plus (or minus) maximum value and inputs the results to a DSP(digital signal processor) 13, which calculates a digital value according to the input data and outputs the digital value to a DA converter 11, etc. The DSP 13 calculates the angle of a rotor shaft, so the rotor shaft angle can be calculated faster than conventional technology (tracking type R/D converter) which includes a closed loop composed of a demodulating circuit, a voltage- controlled oscillator, etc., and performs a sort, of PLL control, so that a fast response can be made.  The rotor shaft angle is found through digital operation, so the need for a compensating circuit for a temperature drift which was needed before for the conventional technology is eliminated, and consequently the whole constitution is therefore simplified to lower the cost.

Abstract: PURPOSE:To perform a cloth-quantity detection with high accuracy and to set the optimum water level and water flow strength by constituting an apparatus of a motor for driving a washing and dehydrating tub and an agitating blade, a feed valve, a level switch part, a motor characteristic detector for detecting a change of motor voltage or current, and a control circuit part. CONSTITUTION:A control circuit part 8 inputs a detected output given by a level switch part 6 and raises a water level by a specified quantity when the value of the detected output is larger than a first threshold value corresponding to the upper limit of a proper cloth quantity range. Further, when the value of the detected output is less than the first threshold value and larger than a second threshold value corresponding to the lower limit of the proper cloth quantity range, a value detected by a motor characteristic detector 7 is compared with a reference value as to whether the detected value is larger or smaller than the reference value. Then, if the detected value is larger than the reference value, a water flow is weakened and if the former is smaller than the latter and a detected water level is less than the second threshold value, the detected output of the level switch part 6 is inputted again while the water level and water flow strength are left as they are. The power application to a motor 2 and the opening and closing motion of a feed valve 5 are controlled so that the operation of weakening and inputting continues until the end of an agitation process.
